The aim of the final work was to describe the MIG / MAG PMC welding process and to examine the weld made by this process. In the introductory part, we talked briefly and in general about welding, and the history of welding. Through the theoretical part, the parameters and processes that the classical MIG / MAG procedure includes are described in detail. The description of the classic process was followed by a description of the pulsed MIG / MAG procedure, which includes the MIG-MAG PMC procedure. Through the description of the PMC procedure, it is possible to see how complex the procedure is, but also productive, while achieving quality results. In the last part of the paper, a complete description of the experimental part of this final work is given, which consists of PMC welding, cutting the cross section of the welded part, grinding, and hardness testing. By grinding the cross section of the weld, we obtained a clearly visible insight into the macrostructure. Then, studying the macrostructure, differences between the melting zone, zone of heat influence and base material were observed, and the weld height was measured, which had a value between 3 and 3.5 mm. At the very end, we measured the hardness by the Vickers method and concluded that there were no significant differences in the hardness in the weld and the base material.
