Abstract
Welding apparatus is disclosed for collecting and disposing of the extraneous work piece particles thrown off during the machining and, in particular, the welding of the workpiece. The welding apparatus comprises a welding chamber for receiving the work piece and for establishing a welding environment about the work piece. The welding chamber has an opening and an input port for introducing a non-reactive gas into the welding chamber to establish the welding environment within the welding chamber. An output port is associated with its welding chamber for permitting the escape of the non-reactive gas therefrom. A manifold is disposed about the output port for receiving and collecting the non-reactive gas and the work piece particles suspended therein. A sealing assembly is associated with the opening for operating in a first mode for sealing the opening to prevent escape of the non-reactive gas except through the output port and the manifold means, and in a second mode to permit escape of the non-reactive gas through the opening.
