Abstract
Technological peculiarities of 4.4 kW Nd:YAG laser welding of medium-carbon steel of the Fe-Cr-Mn-Si alloying system, 3.0 to 10.4 mm thick, in one pass with through penetration have been studied. Compared with argon-arc welding, the present welding method provides 6-12 times reduction of time of machine welding, 2.5-4.5 times decrease in power consumption and 12 times decrease in consumption of filler metal.
