This study has been made in order to obtain the basic guide for MIG spot welding of commercial aluminum alloys. In this study the effects of welding parameters such as welding current, arc voltage and arc time on MIG spot welds were investigated together with argon gas flow rate and after flow time. And the welding parameter guide for various sheet thicknesses was also chosen. To lower variations in strengths of MIG spot welds the use of a mechanized torch which is regarded as a kind of pulldoi:10.2207/qjjws1943.33.8_654 fatcat:rwaikkpxpbhcrk5gj6npnkn5pm
