Welding apparatus and method for forming electrical connections

An exothermic welding system uses compressible layers of disposable refractory batting (86,87,88) or gaskets to form a weld chamber for parts (84,85) to be welded. The parts (84,85) to be welded are layered with the batting (86,87,88) between a base (49) and a crucible platen (66) supported by a cla...

description	An exothermic welding system uses compressible layers of disposable refractory batting (86,87,88) or gaskets to form a weld chamber for parts (84,85) to be welded. The parts (84,85) to be welded are layered with the batting (86,87,88) between a base (49) and a crucible platen (66) supported by a clamping fixture (30). The layered batting (86,87,88) is provided with the holes (89) intersecting the parts (84,85) to be welded. The holes (89) form the weld chamber. The crucible platen (66) is provided with a chamber (91) for the exothermic material which when ignited forms molten metal which flows through a tap hole into the weld chamber. When the weld is made, the fixture is opened (30) and the batting (86,87,88) is discarded. The invention concerns also a method of forming the welded connection by compressing the layered batting (86,87,88) and the parts (84,85) to be welded to form the disposable weld chamber enabling a wide variety of connections not requiring a large inventory of special refractory mold parts.
