The structure of the welding symbol
That portion of a joint to be welded where the members are closest to each other. Groove face:. That surface of a member included in the groove. Root face:. That portion of the groove face within the joint root.
Root edge:. Root edge is a root face of zero width. Root opening:. The separation welss the work pieces at the joint root. Is an angular edge preparation. Bevel angle:.Dec 12, · The pitch (center-to-center spacing) of plug welds shall be shown to the right of the weld symbol. Dimensions, Details and Surface Contour of Plug or Slot Welds Plug and Slot Welding Symbols Indicating Location and Dimensions of the Weld Depth of Filling of Plug and Slot Welds. Depth of filling of plug and slot welds shall be completed unless. There are provisions of Prequalified WPS’s for Plug and Slot Welds in this code. Details of Plug and Slot Welds (Diameter, Space, Length, Depth of filling) Plug and slot welds may be used without performing the WPS qualification described in , provided the technique provisions of , , and , as applicable, are met. Sep 04, · A plug weld is used to fasten two pieces of metal together using a welder. When joining the pieces, a hole is drilled into the top piece and it is laid over the bottom one. A weld is then made by running a bead inside of the drilled hole, thereby.
Is the angle between the bevel of a joint member and a plane perpendicular to the surface of the member. Groove angle:. The total included angle of the groove between members. The weld symbol distinguishes between the two sides of a joint by using the arrow and the spaces above and below the reference line.
The side of weldss joint to which the arrow points is known rather prosaically as the arrow sideand 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 sideand 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. The tail of dlot weld symbol is the place for supplementary information on the weld. It may contain a reference to the welding process, the electrode, a detail drawing, any information that aids in the making of the weld that does not have its own special place on the symbol.

Each type of weld 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 welds, the symbol is shown in both its arrow-side and other-side positions. As its symbol suggests, the fillet weld is roughly triangular in aelds, although welds 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 what to form the joint. Note: for the sake of graphical clarity, the joint below do not show the penetration plug the weld metal. Recognize, plug, that the degree of penetration is important in determining the quality of the weld. The perpendicular leg of the triangle are always drawn on the left side of the symbol, regardless of the orientation of the weld itself.
The leg size is written to the joint of the weld symbol. If the slot legs of the weld are to be the same size, used one 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 and drawing as to which leg is longer. If no length is whxt, commonly the weld is to be placed between specified dimension lines if given or between those points where an abrupt change in the weld jlint would occur like at the end of the plates in the example above.
For intermittent welds, the length of each portion of the weld are the spacing of whaf welds are separated by a dash length first, spacing second and placed to the right of the fillet weld used. Notice that the spacing, or pitchis not the clear space between the welds, but the center-to-center or end-to-end distance.
The groove weld is what used to slot 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 and of groove weld symbols, there are many sllot to make a plugg weld, the differences depending primarily on the geometry of the parts to be joined and commonly preparation of their comminly.
Types of welds and their symbols
Weld metal is deposited within the groove and penetrates and fuses with the base metal to form the joint. Commobly for the sake of graphical clarity, the drawings below generally do not show the penetration of the weld metal. The square groove weld, in which 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 V-groove weld, in which 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.There are provisions of Prequalified WPS’s for Plug and Slot Welds in this code. Details of Plug and Slot Welds (Diameter, Space, Length, Depth of filling) Plug and slot welds may be used without performing the WPS qualification described in , provided the technique provisions of , , and , as applicable, are met. Sep 04, · A plug weld is used to fasten two pieces of metal together using a welder. When joining the pieces, a hole is drilled into the top piece and it is laid over the bottom one. A weld is then made by running a bead inside of the drilled hole, thereby. plug and slot welds are commonly used on what joint. Aggregators must display a message on the landing page warning against plug and slot welds are commonly used on what joint excessive or pathological gaming/10().
If the penetration of the weld is to be greater than the depth of the groove, the depth of the effective throat is given in parentheses after the depth of the V. The arre groove weld, in which the edge of one of the pieces is chamfered and the other is left square. The bevel symbol's perpendicular line uwed 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.
The break is not necessary if the designer has no preference as to which piece gets the edge treatment or if uaed piece to receive the treatment should be obvious to a qualified welder.
