Abstract

MIG/MAG welding is an assembly process very commonly used in different industries. It has the advantage of being faster, especially on thicker materials, economical and suitable for welding steels. Stainless steels are very well suited for metal assembly applications with an attractive compromise between strength and density, reasonable manufacturing cost and good MIG/MAG weldability. In this paper, the present work is oriented the use of the MAG welding process for the mechanical characterization of a welded lap joint for an assembly of 304L stainless steel sheets. The tensile shear tests show that the load/displacement curves (i.e. mechanical characteristics) are affected by the variation in currents of welding. The tensile strength increases with increasing in current of welding. The fracture strength is reduced from 200 A of the current of welding.
