Arc Welding: Arc welding uses a welding power supply to create and maintain an electric arc between an electrode and the base material to melt metals at the welding point. Aluminum parts have been largely been joined by means of MIG (Metal Inert Gas) welding In lightweight car manufacturing. This technique is principally used to make joints between castings and extruded sections, as well as sheet-metal parts.
Remote Laser Welding: Remote laser welding or, “welding on the fly”, combines a robot with either a fixed (shown) or scanning optic welding head to position the focused laser beam on the workpiece. It takes only a few seconds to join components, such as car doors, with high integrity laser welds.
Stud Welding: Stud welding is a technique similar to flash welding where a fastener or specially formed nut is welded onto another metal part, typically a base metal or substrate. Stud welding, also known as "drawn arc stud welding", joins a stud and another piece of metal together by heating both parts with an arc. The stud is usually joined to a flat plate by using the stud as one of the electrodes.
