The work is devoted to evaluation of the impact of lens focus scanning along the laser radiation axis in laser and laser-arc welding on welding-technological properties of the processes and physicomechanical characteristics of weld metal in joints of low-alloyed and high-alloyed steels. It is noted that the effectiveness of welding processes here can be increased by optimization of frequency and amplitude of focus scanning. 12 Ref., 2 Tables, 9 Figures.
Keywords: laser welding, hybrid laser-MIG welding, carbon steel, stainless steel, technological experiments, energy input
