The vector stencils library "Welding" contains 38 welding joint symbols to identify fillets, contours, resistance seams, grooves, surfacing, and backing. This is a complete penetration butt weld (compound butt weld placed first followed by a fillet weld). This is ideal for tee joints, as well as lap joints where the two pieces are parallel but not in the same plane. Edge. This welding joint is created by cutting or grinding your edges of the material to be joined into a V shape by creating a beveled edge of about 60 degrees into each side of the base material. Different types of groove weld as single side V-Groove, Double side V-Groove, J groove, U groove weld, etc. The elemen- tary symbols are shown in Table 1.
