Abstract
The effect of power modulation frequency and shape of laser radiation pulses on formation of weld metal structure in welding of austenitic steel of 18-10 type was investigated. It is shown that pulse laser radiation can affect solidification of weld metal and formation of fine-grained structure in it. Optimal range of modulation frequency was determined.
