It applies the welding symbols to common types of welds groove, fillet, plug, slot, spot, projection, seam, stud, and edge. Sometimes this symbol may also indicate the type of joint such as a lap joint, or corner joint, or tee joint, or corner joint or butt joint. In intermittent seam welding, the wheels advance to the desired position and stop to make each weld. They should be touching, but a small gap (approximately 1/16″ to 1/8″). For example, a weld symbol without a dimension and without CJP in its tail designates a weld that willAn abbreviation is always placed within the tail of the welding symbol to indicate the use of a specific weld process.
