Paper presents the analyses of high strength steels type of 22MnB5, widely used for auto-body passive safety parts. Different surface treatment towards to weldability optimization was subjects of performed experiments. Diffusion processes in surface layer due to variable heat treatment were observed as a substantial influence on strength of welding joints; prospective influence on microstructure and dynamic response outside heat affected zone was also examined.
