AnswerThis is a pretty common question and there is no way to answer it without some pictures. Hopefully this page will shed some light on the subject. A full or complete Full penetration weld symbol weld can be a really thick weld that has been beveled and then penetrated by being filled with multiple weld passes, or it could be a sheet metal joint that is. The weld symbols vary according to the type of joint. Here is an example: This could be a full penetration weld without any bevel. The weld symbol for a full Full penetration weld symbol weld could look something like this. It is full penetration because no depth of penetration is called for. Thats the rule.

As with the bevel, the perpendicular line is always drawn on the left side and the arrow with a break, if necessary points to the piece that receives the edge treatment. Commonly used to join two rounded or curved parts. The intended depth of the weld itself is given to the left of the symbol, with the weld depth shown in parentheses. Commonly used to join a round or curved piece to a flat piece. As with the flare-V, the depth of the groove formed by the two curved surfaces and the intended depth of the weld itself are given to the left of the symbol, with the weld depth shown in parentheses. The symbol's perpendicular line is always drawn on the left side, regardless of the orientation of the weld itself. Both symbols indicate that complete joint penetration is to be made with a single-sided groove weld. When a backing bar is used to achieve complete joint penetration, its symbol is placed across the reference line from the basic weld symbol. If the bar is to be removed after the weld is complete, an "R" is placed within the backing bar symbol. The backing bar symbol has the same shape as the plug or slot weld symbol, but context should always make the symbol's intention clear. Weld metal is deposited in the holes and penetrates and fuses with the base metal of the two members to form the joint. For plug welds, the diameter of each plug is given to the left of the symbol and the plug-to-plug spacing pitch is given to the right. For slot welds, the width of each slot is given to the left of the symbol, the length and pitch separated by a dash are given to the right of the symbol, and a detail drawing is referenced in the tail. The number of plugs or slots is given in parentheses above or below the weld symbol. The arrow-side and other-side designations indicate which piece contains the hole s. If the hole is not to be completely filled with weld metal, the depth to which it is to be filled is given within the weld symbol. More about weld symbols. Subscribe To This Site. Full penetration Weld and Weld symbol Question from reader "Whats a full penetration weld? Answer This is a pretty common question and there is no way to answer it without some pictures. For thin parts, it is possible to achieve full penetration of the weld. For thicker parts, edge preparation may have to be done to achieve the welding. There are nine different types of butt joints: They are shown in Fig. Welds are also classified according to their position into flat, horizontal, vertical and overhead. Flat welds are the most economical to make while overhead welds are the most difficult and expensive. The main use of butt welds is to connect structural members, which are in the same plane. A few of the many different butt welds are shown in Fig. There are many variations of butt welds and each is classified according to its particular shape. Each type of butt weld requires a specific edge preparation and is named accordingly. The proper selection of a particular type depends upon: Size of the plate to be joined; welding is by hand or automatic; type of welding equipment, whether both sides are accessible and the position of the weld. Butt welds have high strength, high resistance to impact and cyclic stress. They are most direct joints and introduce least eccentricity in the joint. But their major disadvantages are: Therefore, field butt joints are rarely used. To minimise weld distortions and residual stresses, the heat input is minimised and hence the welding volume is minimised. This reduction in the volume of weld also Indian Institute of Technology Madras. Hence for thicker plates, double Butt welds and U welds are generally used. For a butt weld, the root gap, R, is the separation of the pieces being joined and is provided for the electrode to access the base of a joint. The smaller the root gap the greater the angle of the bevel. The depth by which the arc melts into the plate is called the depth of penetration [Fig. Roughly, the penetration is about 1 mm per A and in manual welding the current is usually A. Therefore, the mating edges of the plates must be cut back if through-thickness continuity is to be established. This groove is filled with the molten metal from the electrode. The first run that is deposited in the bottom of a groove is termed as the root run [Fig. For good penetration, the root faces must be melted. Simultaneously, the weld pool also must be controlled, preferably, by using a backing strip. The symbolic representation includes elementary symbols along with a supplementary symbol, b a means of showing dimensions, or c some complementary indications. Elementary symbols represent the various categories of the weld and look similar to the shape of the weld to be made. Combination of elementary symbols may also be used, when required. Elementary symbols are shown in Table 3. Supplementary symbols characterise the external surface of the weld and they complete the elementary symbols. Supplementary symbols are shown in Table 3. In this case, the instruction is that you should perform the weld on-site, rather than doing it in a workshop. The other alternative is a circle, which indicates that you should weld all the way around the joint. In other words, you should start and stop at the same point, just as a circle does. If the leader line bends in the case of bevel or J-groove welds , this means that the arrow is pointing to an area which should be chamfered. At the face of the weld symbol, you may see a small arc or straight line. This is supposed to tell you the finish that your weld should be left with. A concave arc should result in a concave finish; a convex arc should result in a convex finish; a flat line should result in a flat finish. If a small box or rectangle can be found on the opposite side of the reference line to the weld symbol, this suggests that a backing strip should be placed on the other side of the joint. If a back weld is needed, it will be indicated by a small semi-circle on the other side of the reference line to the weld symbol. Flash and upset welds are depicted by a single vertical line crossing straight through the reference line. A row of asterisks or stars indicates that resistance spot welds should be used; resistance seam welds are pictured with a pattern that resembles overlapping zigzag lines or a row of small diamonds. If you see a flush contour symbol with one of these welds, then you should remember to make the exposed surface flush. These common joints are made when two members with flat surfaces over lap each other. The connection is normally made with fillet welds along the edges of the connected parts. Tee Joints: In this type of connection one plate element "T"'s into another. The joint can be made with fillet, partial penetration, or full penetration welds. Corner Joints: Corner joints are a special type of Tee joint. Edge joints: This type of connection joins the edges of two plate elements laid together has show in Figure 5. The connection is made with partial penetration welds. The edges are often times prepared with grooves so that the weld can penetrate deeper. Groove welds are generally used to fill the gap between the two pieces being connected. They are called groove welds because the edges of the materials being joined are prepared so that there is a groove of some shape formed when the pieces are first laid together. The weld metal fills the groove. A CJP weld completely fills the gap between the two pieces. Parts A, B, and C of Figure 5. CJP welds made with appropriate filler material are stronger than the base metals that they connect, so strength calculations are not necessary. A PJP weld only fills a portion of the gap as seen in Figure 5. PJP welds are used when it is not required to develop the full strength of the connected parts to transfer the load. Figure 5. Fillet welds do not penetrate the gap between the parts being connected. A fillet weld generally has a triangular cross section with one leg of the triangle being attached to each piece being connected..

Hotwife personals Watch Mature women bondage Video naked nani. If the engineer specifies a joint or weld that has not been prequalified it is necessary for the welders to go through the qualification process to develop a new qualified welding procedure. The certification process requires the welder to create the weld on a sample using the materials, procedure, and position that will be used for making the final connection. The sample is tested to insure that it meets specifications. Once a welder demonstrates that they can consistently create a weld that meets performance specifications then they are certified to make that particular weld. The SCM Table SCM pages through presents that design parameters for the most common prequalified welds used for structural building connections. A means for communicating the intent of the designer to the welder through standard weld symbols has been developed by the AWS. A table defining the weld symbols for prequalified welded joints is included in the SCM on page You should take some time to examine this table. Pay particular notice to the notes at the bottom of the table. As an engineer you need to understand the language of the symbols or you may not get the weld that you are expecting. Each AWS standard prequalified joint has a table associated with it. The table gives the geometrical and material parameters associated with the joint. Typically a figure is given to define the different dimensional quantities. The associated table gives the acceptable parameters associated with each dimensional quantity. The table also assigns a joint designation to each weld for each process. This designation directs the welder to the AWS welding procedure associated with the weld. As a design engineer you should be aware of the factors affecting weld quality, however it is not the responsibility of the designer to check the quality of the welds. There are quite a number of factors affecting the quality of a weld. A good quality control program will have procedures in place to ensure that welds are of appropriate quality. The elements of that program will include the use of prequalified welding procedures, performed by welders that have been certified to perform the designated weld, qualified welding inspectors present on the job, and the specification of specialized weld inspection techniques as required. Inspection of welds must be done by qualified individuals. Most engineers are not qualified to determine the quality of weld. The arrow-side and other-side designations indicate which piece contains the hole s. If the hole is not to be completely filled with weld metal, the depth to which it is to be filled is given within the weld symbol.

Learn how to read common welding symbols and their meaning. The structure of the welding symbol The horizontal line — called the reference line — is the anchor to which all the other welding symbols are tied. Types of welds and their symbols Each welding position has its own basic symbol, which is typically placed near the center of the reference line and above or below it, depending on which side of the joint it's on. Related Articles. Troubleshooting Weld Defects. The joint is reasonably strong, but its use is not recommended when the metals are subject to fatigue or impact loads. Prepa-ration of the joint is simple, since it only requires match-ing the edges of the plates together; however, as with any other joint, it is important that it is fitted together correctly for the entire length of the joint. It is also important that you allow enough root opening for the joint. Figure shows an example of this type of joint. The purpose of grooving is to give the joint the required strength. When you are using a grooved joint, it is important that the groove angle is sufficient to allow the electrode into the joint; otherwise, the weld will lack penetration and may crack. However, you also should avoid excess beveling because this wastes both weld metal and time. Depending on the thickness of the base metal, the joint is either single-grooved grooved on one side only or double-grooved grooved on both sides. As a welder, you primarily use the single-V and double-V grooved joints. The single-V butt joint fig. Each member should be beveled so the included angle for the joint is approximately 60 degrees for plate and 75 degrees for pipe. Preparation of the joint requires a special beveling machine or cutting torch , which makes it more costly than a square butt joint. It also requires more filler material than the square joint; how-ever, the joint is stronger than the square butt joint. But, as with the square joint, it is not recommended when subjected to bending at the root of the weld. The double-V butt joint fig. Compared to the single-V joint, preparation time is greater, but you use less filler metal because of the narrower included angle. Because of the heat produced by welding, you should alternate weld deposits, welding first on one side and then on the other side. This practice produces a more symmetrical weld and minimizes warpage. Remember, to produce good quality welds using the groove joint, you should ensure the fit-up is consistent for the entire length of the joint, use the correct groove angle, use the correct root opening, and use the correct root face for the joint. When you follow these principles, you produce better welds every time. Other standard grooved butt joint designs include the bevel groove, Jgroove, and U-groove, as shown in figure There are many types of butt welds, but all fall within one of these categories: A single welded butt joint is the name for a joint that has only been welded from one side. A double welded butt joint is created when the weld has been welded from both sides. With double welding, the depths of each weld can vary slightly. A closed weld is a type of joint in which the two pieces that will be joined are touching during the welding process. An open weld is the joint type where the two pieces have a small gap in between them during welding. Workpiece thickness limits per joint type[citation needed] Joint type Thickness Square joint Up to 14 in 0. Flag for inappropriate content. Related titles.

Margaret Xxx Watch Teasing girls pics Video Jamica Porn. Unless otherwise stated, the unit of measurement is usually the inch. A number located to the left of your weld symbol tells you the width of the weld, while a number on the right of the weld symbol indicates the length of the weld. If no length is given, then you should assume that it should continue for the entire length of the joint. Sometimes these numbers may be contained within parentheses, in which case they indicate uneven fillet weld lengths. Just as with the weld symbols, numbers below the reference line apply to welds on the same side of the joint as the arrow; numbers above the reference line apply to welds on the opposite side of the joint. With regards to intermittent fillet welds, the pitch will be placed to the right of the weld symbol. For chain intermittent fillet welding, the dimensions will appear on both sides of the reference line: Numbers placed to the right of arc spot and arc seam weld symbols indicate the distance that you should leave between the centers of each weld. Certain symbols will have numbers in parentheses either above or below the symbol, which means that a specific number of those welds should be completed. If you see a number placed within the actual weld symbol itself, this will refer to an angle between two beveled edges or the size of a root opening. However, if you see a whole number such as 45 , this refers to the total angle between two beveled edges. One possibility is a small flag symbol. If the two legs of the weld are to be the same size, only one dimension is given; if the weld is to have unequal legs much less common than the equal-legged weld , both dimensions are given and there is an indication on the drawing as to which leg is longer. The length of the weld is given to the right of the symbol. If no length is given, then the weld is to be placed between specified dimension lines if given or between those points where an abrupt change in the weld direction would occur like at the end of the plates in the example above. For intermittent welds, the length of each portion of the weld and the spacing of the welds are separated by a dash length first, spacing second and placed to the right of the fillet weld symbol. The groove weld is commonly used to make edge-to-edge joints, although it is also often used in corner joints, T joints, and joints between curved and flat pieces. As suggested by the variety of groove weld symbols, there are many ways to make a groove weld, the differences depending primarily on the geometry of the parts to be joined and the preparation of their edges. Weld metal is deposited within the groove and penetrates and fuses with the base metal to form the joint. The groove is created by either a tight fit or a slight separation of the edges. The amount of separation, if any, is given on the weld symbol. The edges of both pieces are chamfered, either singly or doubly, to create the groove. The angle of the V is given on the weld symbol, as is the separation at the root if any. If the depth of the V is not the full thickness — or half the thickness in the case of a double V — the depth is given to the left of the weld symbol. The edge of one of the pieces is chamfered and the other is left square. The bevel symbol's perpendicular line is always drawn on the left side, regardless of the orientation of the weld itself. The arrow points toward the piece that is to be chamfered. This extra significance is emphasized by a break in the arrow line. Hopefully this page will shed some light on the subject. The weld symbols vary according to the type of joint. Another example of a full penetration weld is this: Copyright WeldingTipsandTricks. Webster's defines welding as "to unite metallic parts by heating and allowing the metals to flow together The process of welding is quite complex and the strength of welds is highly dependent on metallurgy, welding procedure, and the skill of the welder. There are multiple processes and methods for accomplishing this complex task. There are a couple of points to emphasize. There are many welding processes, however we will focus on the two most common processes used in structural steel fabrication:. The SAW process results in more consistent weld an a strength bonus is given to some welds created with the SAW process. This specification is particularly important to welders for determining how to accomplish welds designed by engineers. Engineers need to have some familiarity with the material requirements of the AWS D1. Metallurgy has a strong influence on the ability to weld different types of steel. It is important to match weld materials to the base metals that are being connected. The primary reference for matching filler materials to base metals is AWS D1. The table is important for engineers when they specify the weld electrodes to be used for the connections that they design. In this basic text, we will use the following electrodes indicated in Table 5. While this table is basically adequate for most typical projects, for real projects, you should match the requirements of the AWS. There are five basic types of welded joints. The joints are depicted in Figure 5. They are:. Butt Joints: Butt joints are formed when two plates are butted together. The connection is normally made with a full or partial penetration weld. The edges of the plate are often prepared so that the weld can penetrate deeper into the butt joint. Some times the plates are held apart slightly for the same reason.

The weld locations are defined by specifying, a position of the arrow line, b position of the reference line, and c the position of the symbol. More details of weld representation may be obtained from IS For butt welds the most critical form of loading is tension applied in the transverse direction. It has been observed from tests conducted on tensile coupons containing a full penetration butt weld normal to the applied load that the welded joint had higher strength than the parent metal itself. The yield stress of the weld metal and the parent metal in the HAZ region was found to be much higher than the parent metal. The butt weld is normally designed for direct tension or compression. However, a provision is made to protect it from shear. Design strength value is often taken the same as the parent metal strength. For design purposes, the effective area of the buttwelded connection is taken as the effective length of the weld times the throat size. Effective length of the butt weld is taken as the length of the continuous full size weld. The throat size is specified by the effective throat thickness..

The effect of the stress concentration at the corner of the joint between two. To avoid stress concentrations due to abrupt changes of width, taper the wider plate. The depth of groove is measured Full penetration weld symbol the surface of the joint to the bottom of the preparation. The actual weld size is again measured from the surface of the groove through the bottom of the groove but now includes the expected penetration of the weld.

The root opening, when used, dimensions the space between the joint to be welded and visit web page placed inside the weld symbol. The groove angle is also placed inside the weld symbol and is given in degrees. J grooves angles may be detailed elsewhere on the drawing. The root opening and groove angle are separate elements and may or may not appear together depending on the joint requirements. On some drawings the root opening or groove angle will be covered in a note or specification on the drawing for all similar symbols, and does not appear on the symbol.

The elements for these are Full penetration weld symbol on the bottom of the reference line opposite the weld symbol or in the case of the spacer on the reference line.

If link backing bar is to be removed the symbol will contain an R for remove after welding. Since Full penetration weld symbol back and backing weld symbol look the same you must look for details to see which weld applies.

Common supplementary symbols used with groove welds are the melt-thru and backing bar symbols. Both symbols indicate that complete joint penetration is to be made with a singlesided Full penetration weld symbol weld.

However, you also should avoid excess beveling because this wastes both Full penetration weld symbol metal and time. If it is sitting below the reference line, then the weld should be placed in the exact position that the arrow is pointing to i. If the weld symbol is sitting on top of the reference line, the weld should be placed on the opposite side of the joint to the arrow. If — on the other hand — the symbol is located on both the top and the bottom of the reference line, then you should weld on both sides of the joint.

It is Full penetration weld symbol to have different symbols on the top and the bottom of the reference line, in which case two different types of welds should be performed on either side of the joint. Resistance spot, resistance seam, flash and upset weld symbols bear no significance with regards to on which side of the reference line they are placed, or on which side of the joint they should fall.

The horizontal line — Full penetration weld symbol the reference line — is the anchor to which all the other welding symbols are tied.

The instructions for making the weld are strung along the reference line. An arrow connects the reference line to the joint that is to be welded. In the example above, the arrow is shown growing out of the right end of the reference line and heading down and to the right, but many other combinations are allowed.

Quite often, there are two sides to the joint to which the arrow points, and therefore two potential places for a weld. For example, when two steel plates are joined together into a T shape, welding may be done on either side of the stem of the T. The weld symbol distinguishes between the two sides of a joint Full penetration weld symbol using the arrow and the spaces above and below the reference line. The side of the joint to which the arrow points is known rather prosaically as the arrow side, and its weld is made according to the instructions given below the reference line.

The other side of the joint is known even more prosaically as the other side, and its weld is made according to the instructions given above the reference line. The flag growing out of the junction of the reference line and the arrow is present if the weld is to be made in the field during erection of the structure. A weld symbol without a flag indicates that the weld is to be made in the shop. In older drawings, a field weld may be denoted by a filled black circle at the junction between the arrow and the reference line.

Each welding position has its own basic symbol, which is typically placed near the center of the reference line and above or below it, depending on which side of the joint it's on. The symbol is a small drawing that can usually be interpreted as a simplified cross-section of the weld.

In the descriptions below, the symbol is shown in both its arrow-side and other-side positions. Fillet Weld. Groove Welds. Huge ebony bbw azz Full penetration weld symbol and Slot Welds.

As its symbol suggests, the fillet weld is roughly triangular Full penetration weld symbol cross-section, although its shape is not always a right triangle or an isosceles triangle. Weld metal is deposited in a corner formed by the fit-up of the two members and penetrates and fuses with the base metal to form the joint. Recognize, however, that the degree of penetration is important in determining the quality of the weld.

The perpendicular leg of the triangle is always drawn on the left side of the symbol, regardless of the orientation of the weld itself. The leg size is written to the left of the weld symbol.

If the two legs of the weld are to be the same size, only Full penetration weld symbol dimension is given; if the weld is to have unequal legs much less common than the equal-legged weldboth dimensions are given and there is an indication on the drawing as to which leg is longer. The length of the weld is given to the right of the symbol.

If no length is given, then Full penetration weld symbol weld is to be placed between specified dimension lines if given or between those points where an abrupt change in the weld direction would occur like at the end of Full penetration weld symbol plates in the example above.

For intermittent welds, the length of each portion of the weld and the spacing of the welds Full penetration weld symbol separated by a dash length first, spacing second and placed to the right of the fillet weld symbol. Full penetration weld symbol groove weld is commonly used to make edge-to-edge joints, although it is also often used in corner joints, T joints, and joints between curved and flat pieces.

As suggested by the variety of groove weld symbols, there are many ways to make a groove weld, the differences depending primarily on the geometry of the parts to be joined and the preparation of their edges. Weld metal is deposited within the groove and penetrates Full penetration weld symbol fuses with the base metal Full penetration weld symbol form the joint. The groove is created by either a tight fit or a slight separation of the edges.

The amount of separation, if any, is given on the weld symbol. The edges of both pieces are chamfered, either singly or doubly, to create the groove. The angle of the V is given on the weld symbol, as is the separation at the root if any. If the depth of the V is not the full thickness — or half the thickness in the case of a double V — the depth is given to the left of the weld symbol. The edge of one of the pieces is chamfered Full penetration weld symbol the other is left square.

The bevel symbol's perpendicular line is always click on the left side, regardless of the orientation of the weld itself. The arrow points toward the piece that is to be chamfered. This extra significance is emphasized by a break in the arrow line.

The break is not necessary if the designer has no preference as to which piece gets the edge treatment or if the piece to receive the treatment should be obvious to a qualified welder.

Angle and depth of edge treatment, effective throat and separation at the root are described using the methods discussed in the V-groove section.

The edges of both pieces are given a concave treatment. Depth of edge treatment, effective throat and separation at the root are Full penetration weld symbol using the methods discussed in the V-groove section. The edge of one of the pieces is given a concave treatment and the other is left square. It is to the U-groove weld what the bevel groove weld is to the V-groove weld.

As with the bevel, the perpendicular line is always drawn on the Full penetration weld symbol side and the arrow with a break, if necessary points to the piece that receives the edge treatment. Commonly used to join two rounded or curved parts.

The intended depth of the weld itself is given to the left of the symbol, with the weld depth shown in parentheses. Commonly used to join a round or curved piece to a flat Full penetration weld symbol. As with the more info, the depth of the groove formed by the two curved surfaces and the intended depth of the weld itself are given to the left of the symbol, with the weld depth shown in parentheses.

The symbol's perpendicular line is always drawn on the left side, regardless of the orientation of the weld itself. Both symbols indicate that Full penetration weld symbol joint penetration is to be made with a single-sided groove weld.

When a backing bar is used to achieve complete joint penetration, its Full penetration weld symbol is placed across the reference line from the basic weld symbol. If the bar is to be removed after the weld is complete, an "R" is placed within the backing bar symbol. The backing bar symbol has the same shape as the plug or slot weld symbol, but Full penetration weld symbol should always make the symbol's intention clear. Weld metal is deposited in the holes and penetrates and fuses with the base metal of the two members to form the joint.

For plug welds, the diameter of each plug is given to the left of the symbol and the plug-to-plug Full penetration weld symbol pitch is given to the right. For slot welds, the width of each slot is given to the left of the symbol, the Full penetration weld symbol and pitch separated by a dash are given to the right of the symbol, and a detail drawing is referenced in the tail. The number of plugs please click for source slots is given in parentheses above or below the weld symbol.

The arrow-side and other-side designations indicate which piece contains the hole s. If the hole is not to be completely filled with weld metal, the depth to which it is to be filled is given within the weld symbol.

The edge of one of the pieces is given a concave treatment and the other is left square. It is to the U-groove weld what the bevel groove weld is to the V-groove weld. Welds have one tensile limit state and one shear limit state. Typically the SCM denotes the nominal capacities of each as R n. The connected parts are referred to as the "base metal". There are two base metal components associated with each weld. The strength of both base metals in the vicinity of the weld needs to be considered. The base metal with the least strength controls the base metal capacity. Introduction to Welding. Finding Forces in Welded Connections. Effective Areas and Size Limitations of Welds.

The welding process has been around for thousands of years. Welding Processes There are many welding processes, however we will focus on the two most common processes used in structural steel fabrication: A manual process that is typically used when welding in the field. It is also used frequently when welding in a fabrication shop. An automated welding process that frequently used when welding in a fabrication shop. Weldability of Metals Metallurgy has a strong influence on the ability to weld different types of steel. Hopefully this page will shed some light on the subject. The weld symbols vary according to the type of joint. Another example of a full penetration weld is this: Copyright WeldingTipsandTricks. Unless otherwise stated, the unit of measurement is usually the inch. A number located to the left of your weld symbol tells you the width of the weld, while a number on the right of the weld symbol indicates the length of the weld. If no length is given, then you should assume that it should continue for the entire length of the joint. Sometimes these numbers may be contained within parentheses, in which case they indicate uneven fillet weld lengths. Just as with the weld symbols, numbers below the reference line apply to welds on the same side of the joint as the arrow; numbers above the reference line apply to welds on the opposite side of the joint. With regards to intermittent fillet welds, the pitch will be placed to the right of the weld symbol. For chain intermittent fillet welding, the dimensions will appear on both sides of the reference line: Numbers placed to the right of arc spot and arc seam weld symbols indicate the distance that you should leave between the centers of each weld. Certain symbols will have numbers in parentheses either above or below the symbol, which means that a specific number of those welds should be completed. If you see a number placed within the actual weld symbol itself, this will refer to an angle between two beveled edges or the size of a root opening. However, if you see a whole number such as 45 , this refers to the total angle between two beveled edges. One possibility is a small flag symbol. If the backing bar is to be removed the symbol will contain an R for remove after welding. Since the back and backing weld symbol look the same you must look for details to see which weld applies. Common supplementary symbols used with groove welds are the melt-thru and backing bar symbols. Both symbols indicate that complete joint penetration is to be made with a singlesided groove weld. When a backing bar is used to achieve complete joint penetration, its symbol is placed across the reference line from the basic weld symbol. If the bar is to be removed after the weld is complete, an "R" is placed within the backing bar symbol. The backing bar symbol has the same shape as the plug or slot weld symbol, but context should always make the symbol's intention clear. The joint is reasonably strong, but its use is not recommended when the metals are subject to fatigue or impact loads. Prepa-ration of the joint is simple, since it only requires match-ing the edges of the plates together; however, as with any other joint, it is important that it is fitted together correctly for the entire length of the joint. It is also important that you allow enough root opening for the joint. Figure shows an example of this type of joint. The purpose of grooving is to give the joint the required strength. When you are using a grooved joint, it is important that the groove angle is sufficient to allow the electrode into the joint; otherwise, the weld will lack penetration and may crack. However, you also should avoid excess beveling because this wastes both weld metal and time. Depending on the thickness of the base metal, the joint is either single-grooved grooved on one side only or double-grooved grooved on both sides. As a welder, you primarily use the single-V and double-V grooved joints. The single-V butt joint fig. Each member should be beveled so the included angle for the joint is approximately 60 degrees for plate and 75 degrees for pipe. Preparation of the joint requires a special beveling machine or cutting torch , which makes it more costly than a square butt joint. It also requires more filler material than the square joint; how-ever, the joint is stronger than the square butt joint. But, as with the square joint, it is not recommended when subjected to bending at the root of the weld. The double-V butt joint fig. Compared to the single-V joint, preparation time is greater, but you use less filler metal because of the narrower included angle. Because of the heat produced by welding, you should alternate weld deposits, welding first on one side and then on the other side. This practice produces a more symmetrical weld and minimizes warpage. Remember, to produce good quality welds using the groove joint, you should ensure the fit-up is consistent for the entire length of the joint, use the correct groove angle, use the correct root opening, and use the correct root face for the joint. When you follow these principles, you produce better welds every time. Other standard grooved butt joint designs include the bevel groove, Jgroove, and U-groove, as shown in figure There are many types of butt welds, but all fall within one of these categories: A single welded butt joint is the name for a joint that has only been welded from one side. A double welded butt joint is created when the weld has been welded from both sides. With double welding, the depths of each weld can vary slightly. A closed weld is a type of joint in which the two pieces that will be joined are touching during the welding process. An open weld is the joint type where the two pieces have a small gap in between them during welding..
