Purpose: Main novelty and the aim of the paper is to analyses possibility of dissimilar AG welding of two various grades of steel with significantly different structure. Design/methodology/approach: Two various metals have been checked in welding in order to obtain a high-quality joint of car body elements. The properties of the joint were checked by NDT (Non Destructive Test) and DT (Destructive Tests). Findings: Relations between MAG welding process parameters and the quality of joint. Research limitations/implications: In the future, it can be tested the effect of micro addition of nitrogen or oxygen in gas shielding mixtures of the MAG process. Practical implications: Suggested materials and innovation will not cause problems in the production process provided that the technological regime will be respected. Social implications: Modifying the welding materials and method will not affect the environment and production management methods. Producing of dissimilar welds must translate into production savings. Originality/value: The paper is addressed to manufacturers of low-alloy and advanced high strenth steel for automotive industry.
