Vol. 76, nr 1

21--25

Purpose: In this study, DP 600 (Dual Phase) steel plates having 1 mm thickness were joined by copper-based (CuAl8) wire in gas metal arc brazing technique. Specimens were prepared in joining forms as overlap joint. Design/methodology/approach: Brazing operations were done with five different working angles of 45°, 50°, 60°, 70° and 80°. CuAl8 wires 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 DP 600 steel by gas metal arc brazing technique.

Purpose: In this study, the join ability of dual-phase automotive steel sheets by metal inert gas brazing method was aimed. DP 600 (Dual Phase) steel plate shaving 1 mm thickness were joined by copper-based (CuAl8) wire in gas metal arc brazing technique. Design/methodology/approach: Specimens were prepared in butt joint form. Brazing operations were done with nine different Brazing arc voltage of 10, 10.5, 11, 11.5, 12, 12.5, 13, 13.5and 14 V. A copper-based CuAl8 wire was used as filler metal. Having accomplished the brazing operations; tensile properties of joints were determined, and micro and macro-structures of joints were investigated in order to see the joinability of DP 600 steel by gas metal arc brazing technique. Originality/value: The tensile strength increased from 10 V to 12 V arc voltage and reached the maximum value as 640 MPa, and then decreased with increasing arc voltage.
