Özet

In this study, TRIP 800 (transformation induced plasticity) steel plates having 1.5 mm thickness were joined by copper-based (CuAl8) wire in gas metal arc brazing technique. Specimens were prepared in two different joining forms as butt joint and overlap joint. Both types of brazing operations were done with eight different arc voltages and weld currents as 45, 50, 55, 60, 65, 70, 75 and 80 A. S Cu 6100(CuAl8) wire composed largely of copper serves as the filler metal were used. Having accomplished the brazing operations; tensile properties of joints were detected, and micro and macro-structures of joints were investigated in order to see the joinability of TRIP 800 steel by gas metal arc brazing technique.
