Both the processes of welding and stamping are becoming increasingly more common in the construction of means of transport. Heavily loaded vehicle components should have good plastic properties so that cracks do not occur under operating conditions. Welded joints often crack, especially when they are subjected to additional treatments, such as stamping. In this article, the possibility of MAG welding (Metal Active Gas) of low-alloy steel using (MJC) micro-jet cooling was checked. Then, the made joints were subjected to a stamping test. Weld metal deposit (WMD) was carried out for the classic MAG process and compared with the modern method using MJC. Joint sand stamping tests of low-carbon and low-alloy steel were carried out. Welding with micro-jet-cooling could be considered promising due to the useful structure of WMD. This structure yields better mechanical properties, i.e. higher impact toughness for subzero service. For the first time, it was decided to check the pressure of the sheets welded with an innovative welding process. Then, the samples obtained by welding were subjected to the process of stamping. The result of stamping of welded sheets was investigated. The results of stamping show that only after correct welding process might the expected mechanical properties be achieved.
