The Particularities of the CMT Braze-Welding Process Between Ferritic Stainless Steel - Magnesium Alloy

Jointing of dissimilar materials with the CMT braze-welding process, ferritic stainless steel - magnesium alloy, offers important technical and economic advantages to the automotive industry. In the actual research paper we analyse the opportunity of realizing heterogeneous joints by the CMT process, using a layer of copper as a layer to be deposited firstly on ferritic stainless steel. Macro - and micrographic investigations, corroborated with hardness testing on (Cu-stainless steel, Mg - Cu) deposition by TIG, aim to highlight the process specificities and problems occurring in the interface areas of the joints made
