The edges are often times prepared with grooves so that the weld can penetrate deeper. Groove Welds 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.

A fillet weld generally has a triangular cross section with one leg of the triangle being attached to each piece being connected. Fillet welds are very common and are used for a variety of connections.

A typical fillet weld is shown in Figure 5. These welds fill a slot or hole in one of the pieces being connected with the connection being between the edge of the slot or hole on the one piece and the surface of the other piece.

The welds can be made in conjunction with fillet welds to shorten the lap of two pieces where space is limited. Before a welded joint can be made on a project, it must be proven that the weld can be made using the desired materials and attain the required strength and ductility. Once the joint has been proven, a welding procedure that details how the weld is to be made is published and the procedure is considered to be prequalified.

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 the welding process. Square butt joints[ edit ] The square-groove is a butt welding joint with the two pieces being flat and parallel to each other. This joint is simple to prepare, economical to use, and provides satisfactory strength, but is limited by joint thickness.

The closed square butt weld is a type of square-groove joint with no spacing in between the pieces. This joint type is common with gas and arc welding.

For thicker joints, the edge of each member of the joint must be prepared to a particular geometry to provide accessibility for welding and to ensure the desired weld soundness and strength. The opening or gap at the root of the joint and the included angle of the groove should be selected to require the least weld metal necessary to give needed access and meet strength requirements.

V-joints[ edit ] Single butt welds are similar to a bevel joint, but instead of only one side having the beveled edge, both sides of the weld joint are beveled. In thick metals, and when welding can be performed from both sides of the work piece, a double-V joint is used.

When welding thicker metals, a double-V joint requires less filler material because there are two narrower V-joints compared to a wider single-V joint. Also the double-V joint helps compensate for warping forces.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.
