Dependences of the depth and width of a welded joint on the displacement velocity of stainless steel and aluminium alloy samples irradiated by a 5-15-W repetitively pulsed Nd:YAG laser are obtained. It is shown that for pulse repetition rates of 25-50 Hz and an off-duty ratio of 150-300, the specific power losses on penetration are one-two orders of magnitude lower than in the case of welding by cw and repetitively pulsed CO{sub 2} lasers.
