Underwater welding test chamber
An apparatus is described which is capable of testing a small hand-held welding chamber for use in underwater welding. Specifically, the apparatus includes 2 interconnected chambers, one being elevated above the other. Within the lower chamber, there is a plate on which is positioned a workpiece to be welded. The welding chamber, a tubular welding housing having a side aperture through which the welding gun may be introduced, is positioned radially within the lower chamber with its axis directed to the workpiece. Shielding gas supplied through an inlet to the housing purges the housing of water and escapes into the lower chamber and from there to the upper chamber. By controlling the exhaust flow from the upper chamber, the water pressure in the lower chamber may be adjusted to any desired value, thereby duplicating underwater welding conditions. (16 claims)
