The laser beam welding process has high power density resulting in small heat affected zones and high heating rate and cooling rate.. The laser spot size may vary from 0..2 mm to 13 mm.. Also, the depth of the penetration and the speed of welding are proportional to the amount of power supplied to the welding machine, but it also depends upon the ..
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)..
