Comparative Study Concerning the Mechanical Properties of Welded S355J2+N Steel Using MAG DC+ and Pulsed Mag

Abstract Currently, welded assemblies produced through fusion processes rank among the most widely used assembly methods in the industry. The welding process selection is based on several criteria, particularly those related to the mechanical resistance characteristics of the welded materials. This paper analyses the mechanical properties of a specific material used in creating welded assemblies via MAG DC+ welding technology and Pulsed MAG welding. The study involves applying mechanical tests for tension and bending to specimens of S355J2+N steel. The experimental results indicate that, due to effective heat transfer, initial cracks do not occur in the welded area but rather in regions that are not influenced by the weld joint. Consequently, other considerations related to the welding performed were established.
