A scheme of comprehensive assessment of weld bead geometry

International Journal of Advanced Manufacturing Technology, 2015
Weld bead geometry is a complex multi-input multi-output system. The relation between every individual geometrical feature and welding process parameter of a weld bead is unique, like the weld width, reinforcement height, and penetration depth. A comprehensive assessment scheme for weld bead geometry is proposed.
