Research of laser welding of thin-sheet structural steels by pulsed laser radiation

© 2019 Trans Tech Publications Ltd, Switzerland. Specific features of the formation of welded metals under the pulsed action of laser radiation are described. It is shown that the quality of the technological process of welding depends on the energy characteristics of the laser technological complex, the temperature of the surface layer. The results of experimental studies on the effect of pulsed laser radiation on steel 08YU with the possibility of obtaining a welded seam with the required quality indices are presented
