Abstract
In this study, 1 mm thick DP800 (Double Phase) galvanized coated steel sheets used in the production of automotive body and chassis parts were combined with 1.5 mm thick Al 5182 series sheets. These connections were made using the cold metal transfer (CMT) method of gas arc welding. The applied welding position is determined as the overlap. This application was carried out in a fully automatic robotic system using 1 mm diameter aluminum-based ER4043 (AlSi5) filling wire. After joining processes with the cold metal transfer (CMT) method, tensile strength (MPa), bending test, hardness values (HV), macro and micro tests in the joining areas were examined. In conclusion, the maximum breaking strength was reached at 90 amps (Fm: 4.28 kN). It was observed that heat input affected the intermetallic (IMC) phase formation and thickness. In bending tests, the highest breaking force (295 N) was reached at 85 amperes. Negative effects of evaporative galvanization (incomplete melting, pore formation) were observed in Al-DP steel joints. It was observed that the melting of aluminum positively affected the wetting angle in galvanization.
