The CMT/CMTP braze-welding process is characterized by interruption of a short-arc at low welding current values, which is controlled by an invertor source. Thereby, the used energy is lowered by short time (about 1 μs) before reignition of the electric arc. Because of the offered benefits (joining of thin materials, the possibility of using large diameter wire electrode by low welding current, low heat input values, etc.) is facilitated the achievement of butt, corner and overlap welded joints, between dissimilar materials that have a low welding metallurgical behavior. In this paper is analysed the opportunity to produce heterogeneous braze-welded joints (galvanized steel – aluminum alloy) starting from a factorial experiment which considers three sets of technological parameters. Welded joints quality is evaluated by metallographic examinations and mechanical testing.Keywords: CMT/CMTP process, galvanized steel, aluminium alloy
