ABSTRACT:
A method of holding two separate metal pieces together for welding including the steps of overlapping a portion of one of the metal pieces on a portion of the other metal piece; encasing the overlapping metal piece in a compressible device; drawing the compressible device into an enclosure; and compressing a portion of the compressible device around the overlapping portions of the metal pieces for holding the metal pieces under constant and equal pressure during welding thereof. The preferred apparatus for performing the method utilizes a support mechanism to support the two separate metal pieces in an overlapping configuration; a compressible device surrounding the support mechanism and at least one of the metal pieces; and a compressing device surrounding the compressible device for compressing the compressible device around the overlapping portions of the metal pieces, thus providing constant and equal pressure at all points on the overlapping portions of the metal pieces.
