A lightweight, motorized travel carriage on which seam tracking equipment, a wire feed system and automatic head are mounted.
Straight or curved track sections are attached directly to the workpiece, either by suction cups or bolting. This permits movement of the welding carriage in a continuous path along the weld seam. The skate welder makes it possible to do precision welding on massive structures that cannot be handled on conventional rotating positioners and longitudinal seamers. Skate carriages can be operated in horizontal and vertical directions to make out-of-position welds.
