Abstract (English):
A method of laser bonding aimed for the elimination of welding seam form defects is offered. The results of experiments confirming the impact of laser bonding on a flux layer upon the formation of a structure and quality of a welding seam are stated. The measurement results of metal hardness in welding joints obtained by an offered method and also by arc welding and laser bonding are shown. The results of the mechanical tests of welds obtained by laser bonding on a flux layer are pre-sented.
