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 physico-mechanical 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 focus frequency and amplitude. 12 Ref., 2 Tabl., 9 Fig.
