WELDER WITH POSITIONAL HEAT CONTROL AND METHOD OF USING SAME
摘要
An electric arc welder for producing a weave pattern across a workpiece with a succession of individual weld short runs or bead, each of which has a center portion extending between two transversely spaced edges. The welder comprising a power source, a wire feeder to direct a welding wire through a movable torch to the workpiece and a controller for creating a welding current between the wire and the workpiece. A mechanical device is used to move the torch along the bead and the controller has a program to perform a first weld process while the torch is moving along the center portion and a second weld process when the torch is adjacent the edges, where the first weld process has less heat input than the second weld process.
