Laser Beam Welding: Working, Equipments, Applications & [PDF]
Laser Beam Welding (LBW) is a welding process, in which heat is generated by a high energy laser beam targeted on the workpiece.. The laser beam heats and melts the edges of the workpiece, forming a joint.. The energy of a narrow laser beam is highly concentrated at 10 8 -10 10 W/cm 2, so a weak weld pool is formed very rapidly (for about 10 -6 sec)..
