ABSTRACT:
Interposing a coating-compatible strip material between a coated plate to be welded and a welding electrode that contacts that plate during the welding operation so that a coating-compatible film is applied to the plate during the welding process to prevent the removal of the protective coating of the plate. A device for performing the process includes support means for supporting a supply of strip material and guides for interposing the strip material between the plate and the welding electrode that contacts that plate during the welding operation. The strip material may be contained in a cassette which is adapted to be attached to the device.
