Research in welding at the Idaho National Engineering Laboratory (INEL) is currently concentrating on the development of sensing, modeling, and control schemes for GMAW [1,2]. In the GMAW process, a welding arc is struck between the workpiece and the tip of a consumable wire electrode. The electrode carries the welding current, sustaining the arc. The electrode melts, resulting in the detachment of metal droplets which supply filler metal to the joint [3]. The standard practice for achieving a desired rate and size of metal droplet is to set welding parameters based on past experience.
