Investigation of mechanical properties of MIG-brazed DP600 steel plates using different arc voltage
Journal Title: Journal of Achievements in Materials and Manufacturing Engineering - Year 2016, Vol 75, Issue 2
Abstract
Purpose: In this study, the joinability of dual-phase automotive steel sheets by metal inertgas brazing method was aimed. DP 600 (Dual Phase) steel plates having 1 mm thicknesswere joined by copper-based (CuAl8) wire in gas metal arc brazing technique.Design/methodology/approach: Specimens were prepared in butt joint form. Brazingoperations 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 brazingoperations; tensile properties of joints were determined, and micro and macro-structures of jointswere 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 reachedthe maximum value as 640 MPa, and then decreased with increasing arc voltage.
