ABSTRACT:
A laser welding apparatus is for laser welding an inner joint between first and second bellows diaphragms. The apparatus preferably includes a first clamp having an opening therein and having portions adjacent the opening defining a first clamping surface; and a second clamp having portions defining a second clamping surface, and wherein the first and second clamps are relatively movable to clamp the first and second metal bellows diaphragms together between the first and second clamping surfaces so that the openings in the bellows diaphragms are generally aligned with the opening in the first clamp. The apparatus also preferably includes a laser for generating a laser beam, and a beam directing element positioned in the opening of the first clamp and the openings of the first and second bellows diaphragms for directing the laser beam to weld the inner joint between the first and second bellows diaphragms. The opening of the first clamp and the recess of the second clamp are preferably sized to expose a predetermined radially inwardly extending portion of the first and second bellows diaphragms to facilitate welding with the laser beam. In addition, the apparatus also preferably includes a rotating drive arrangement for relatively rotating the first and second clamps, and the laser beam directing means to weld the inner joint. A non-metallic spacer may be positioned between the bellows diaphragms.
