A durability assessment of a weld joint needs the knowledge of residual stresses and distortion (Ref. 1). Thermal cycle history during welding is a necessary input for simulation of residual stresses. Many investigators have studied heat flow during arc welding analytically, numerically, and experimentally (Refs. 2–6). Analytical methods developed are capable of computing temperature distributi...

Laser-enhanced gas metal arc welding (GMAW) is an innovative process recently proposed and developed at the University of Kentucky (Refs. 1–3), shown in Fig. 1. It adds a relatively low-power laser to conventional GMAW, and the objective is to provide an auxiliary force to help detach the droplet at a desired diameter with a desired welding current. In laserenhanced GMAW, the droplet size is a ...
