Investigation of Mechanical Properties of MIG-Brazed 304 Stainless Steel and EN 10292 Galvanized Steel Joints using Different Current Intensity

In this study, 304 stainless steel and EN 10292 galvanized steel plates having 1 mm thickness were joined by copper-based S Cu 6100(CuAl8) wire in gas metal arc brazing technique. Argon was used as shielding gas and brazing operations were done with gas flow speed as 12 L/min. Brazing operations were done with seven different weld currents as 40, 45, 50, 55, 60, 65, and 70 A. Having accomplished the brazing operations, tensile strengths of joints were tested, and micro and macro-structures of joints were investigated in order to see the joinability of 304 stainless steel and EN 10292 steels using different current intensity by gas metal arc brazing technique.
