A method of laser welding with simultaneous alloying of 2.4060 over the entire depth of the melt bath for connecting the crankcase and the steering knuckle of a truck chassis is described. The results of experimental studies of the macro and microstructure of various zones of laser welding of 35HGSA steel with steel 1.0570 are presented. A comparative analysis of the hardness of the melt zone and the heat affected zones for samples with and without alloying is carried out.
