ABSTRACT:
A device for welding thin metallic diaphragms which can be combined to form a bellows arrangement and method for using same is disclosed. The device uses a pair of weld spools (22), in a spaced apart relationship, each having a circumferential groove (26) formed therein to receive the surfaces defining the inside diameters of the diaphragms. A pressure roller (20) is provided and has a plurality of circumferential grooves (28) formed therein, the axial spacing between the circumferential grooves (28) approximating the desired pitch of the resulting diaphragm convolution. Each of the circumferential grooves (28) receives a surface defining the outside diameter of a diaphragm and pressure is applied thereto by the pressure roller (20). Rotation of the pressure roller (20) and the pair of weld spools (22) by their respective drive shafts (42,32) causes the diaphragms to rotate about their axes permitting a welding torch (50) to weld the surfaces defining the inside diameters of the diaphragms.
