Welding Process: 10 Types of Welding Processes [Diagram, PDF]

 · Laser Beam Welding (LBW) Laser Beam Welding (LBW) is a welding process, in which heat is formed by a high energy laser beam targeted on the workpiece. The laser beam heats and melts the ends of the workpiece, making a joint. In laser welding (LBM) the joint is formed as a sequence of overlapped spot welds or as a continuous weld.

TIG Welding

 · The way these three things come together is pretty simple. First the welder turns on the gas flow, many times by a valve on the TIG torch itself. The gas begins to flow and starts protecting the weld area from the air. The torch is held over the weld joint just far enough for the torch not to touch the metal.
