Abstract
An improved fusion welding system having a heating unit and welding device is adapted for increasing the efficiency of welding a plurality of workpieces. The system preferably presents a single-sided process, and includes first and second electrode wheels operable to heat a portion of the workpieces to a minimum temperature, and a translatable laser cooperatively configured to form a continuous weld within the heated portion. The preferred system provides the advantages of laser welding, such as precision, while enabling weld production at lower laser power outputs or faster welding speeds than conventional laser welding systems.
