Investigation of Mechanical Properties of Butt Joint Form in CMT-Brazed Joints of DP1000 Steel Plates Using Different Current Intensity

Abstract

In this study, DP 1000 (Dual Phase) steel plates having 1.2 mm thickness were joined by copper-based (CuAl8) wire in CMT-brazing (Cold Metal Transfer) technique. Specimens were prepared in joining forms as butt joint. CMT-Brazing operations were done with nine different CMT-Brazing current intensity of 40, 45, 50, 55, 60, 65, 70, 75 and 80 A. CuAl8 wire composed largely of copper serves as the filler metal were used. Having accomplished the CMT-brazing operations; tensile properties of joints were detected, and micro and macro-structures of joints were investigated in order to see the joinability of DP 1000 steel by CMT-brazing technique.
