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.

Purpose: The novelty and the aim of the article is to check the possibility of welding high 9 strength steels with a mixture containing 7000 ppm of nitrogen. Design/methodology/approach: A new welding material and method have been developed in order to obtain a high-quality joint for automotive industry and for antenna holders and towers. The properties of the joint were checked by NDT (Non Destructive test) tests and the strength and fatigue were tested. Findings: Relations between process parameters and the quality of welds. Research limitations/implications: In the future, it can be suggested to investigate the effect of micro addition of nitrogen in gaseous shielding mixtures of the MIG/MAG welding process. Practical implications: The proposed innovation will not cause problems in the production process. Only the innovate shielding gas with micro additives 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: It is to propose a new solution with its scientific justification. The article is addressed to manufacturers of high-strength steel for automotive industry and to manufacturers of antenna components and instrumentation.

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.
