ABSTRACT:
An improved fusion welding system having a perforating device and a heating combination is adapted for welding in tandem a set of adjacent overlapping workpieces. The system preferably includes a first laser that perforates the workpieces to produce an opening spaced from the edges; and the combination preferably includes a second laser and electrode for cooperatively melting fusible material into the opening.
