Purpose: Checking the quality of a joint made with a newly developed method. Design/methodology/approach: A new welding method has been developed in order to obtain a high-quality joint. The properties of the joint were checked by NDT (Non Destructive test) tests and the strength and fatigue strength were tested. Findings: Now, adding to the shielding gas mixture can improve the quality and properties of the weld. Research limitations/implications: In the future, it can be suggested to investigate the effect of nitrogen in other gaseous shielding mixtures of the MAG welding process. Practical implications: The proposed innovation will not cause problems in the production process. Only the shielding gas will be modified without affecting the technological process, management and economic aspects. Social implications: Modifying the welding method will not affect the environment and production management methods. Originality/value: What is new is to propose a new solution with its scientific justification. The article is addressed to manufacturers of structures made of HSS and AHSS steels.
