ABSTRACT:
Welding apparatus for simultaneously applying a number of parallel welding beads to workpieces for welding the workpieces along their intersecting edges into an assembly. A carriage is arranged for rectilinear motion along a path and holds a number of welding arms for movement with the carriage. The welding arms comprise welding stations and are arranged in a spaced apart relationship to one another and in proximity to workpieces held at the welding station so that the arms follow along the workpiece edges when the carriage moves along the path. A controller energizes and de-energizes a bi-directional motor and electric arc welding apparatus in response to signals provided by position sensing switches that sense the position of the carriage along the path and the controller causes the carriage to be automatically returned to its starting position after a welded assembly is removed from the welding station.
