Laser Welding

Laser welding is a fusion joining process that produces coalescence of metals with the heat generated by the absorption of a concentrated, coherent light beam impinging on the components to be joined. The laser beam is focused on a small spot for high power density and directed by optical elements such as mirrors or lenses. It is a noncontact process, with no pressure being applied. Most applications of laser welding can be grouped into one of four major categories: structural, assembly, sealing, and conduction welds. KEYWORDS for this process: hardening, electron beam welding
