A mass production technique is described which can join not only flat pieces, but also tubing, forgings, machined parts and complex metal stampings. In projection welding at least one of the work pieces to be joined receives a small embossment or projection, which is placed there by a previous operation. In projection welding it is not necessary for the two parts to have the same thickness or be of the same material. The shape, form, size and location of the projections varies according to the nature and form of the parts, stock thickness, design of the joints and manufacturing process of the parts. Projection shapes are simple, round dimples, elongated dimples and ringlike dimples. Round shapes are best both from functional and manufacture standpoints. Advice is given on the location of the projections and recommendations are presented for the design of various well components. Lap joints, cross joints, welding studs, machine studs, machined parts, natural projections and indirect fastening are considered.
