An induction welding system employs an induction welding apparatus with an induction welding power supply and a chiller in the same enclosure. An induction welding coil is powered by the induction welding power supply. A variable force press can press together work pieces and an actuator can move the induction welding coil lengthwise along a weld joint. The weld controller repeatably conducts induction welds by controlling the induction welding power supply to power the induction welding coil and controlling the induction welding tooling to at least one of press together work pieces to be welded and move the induction welding coil lengthwise along a weld joint between work pieces to be welded.
