ABSTRACT:
Non-continuous forms are welded on an automatic device using a continuous welding process (e.g., Tungsten Inert Gas Process (TIG) with a continuous welding arc. The noise level of the welding system is below that which is prescribed by the Operational Safety and Health Act (OSHA). The device includes apparatus for indexing and positioning the non-continuous forms relative to the welding electrode. The device further includes apparatus for chilling the non-continuous forms during the welding process, and apparatus for periodically shunting the welding arc away from the non-continuous forms so as to maintain a continuous welding arc.
