Abstract
The purpose of this study is to examine the effect of double pulse Gas Metal Arc Welding (GMAW) and Gas Tungsten Arc Welding (GTAW) on metal droplet transfer, weld bead geometry, weld pool profile and to examine the mechanical properties of the Al 5754 alloy weld joints. Al 5754-Al 5754 aluminum alloy plates were welded with ER 5356 welding wire. No significant defects were found, and full penetration joints were created. The effect of arc welding parameters on the speed and appearance of welding were investigated by means of macrostructure and microstructure characterization of fusion zone. Also, the characters of tensility and micro-hardness being of the welded specimens were measured.
