Abstract
A resistance weld shielding control system includes a computer that is executed to control a fixture to receive and hold at least one part to be welded. The computer also controls one or more electrodes to apply electrical energy to the part for welding the at least one part, and controls a gas delivery system to direct an inert gas onto the part for shielding the part from the ambient atmosphere via a nozzle. The nozzle is configured in the fixture such that the fixture holds the nozzle in a fixed physical relationship to the part.
