The influence of gas metal arc welding on angular distortion of T-joint
Gas Metal Arc Welding (GMAW) or gas metal arc welding is one of the joining technologies and widely used in metal fabrication. The quality of a joint is greatly influenced by the selection of parameter setting of GMAW. One of the quality issues faced in welding is angular distortion. This research f...
