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.

In the paper results of metallographic analyses of joints made by MIG brazing on high strength galvanized steel sheets of H 340LAD + Z EN 10292 are presented. The quality of brazed joints made by SG CuAl8 braze with fluctuating welding rectifier CLOOS 303 MC4 was evaluated. Argon 4,80 was used as gaseous shield. Soldering joints quality was evaluated by destructive testing. The bearing capacity joints were evaluated by STN EN ISO 895 and STN EN 1321. Macrostructure and microstructure analyze of joints were realized too.
