Stud welding refers to a type of welding in which metal fasteners are applied to another piece of metal by a welding arc. Using a stud gun and arc welder, the welding stud is held in place and then forced into the melted area and held into place until the metals solidify again. The process is very quick and created strong bond between the parts. Welding studs are typically made of steel, copper alloy and sometimes plastic, and come in a multitude of thread sizes and lengths. Looking for other welding supplies?
