ABSTRACT:
A compact metal bellows preferably for converting pressure changes into lar motion, has alternating inner and outer welds accomplished by a laser weld technique. An inner weld fixture is provided for deflecting a portion of the bellows away from the very small beam spot of the laser weld process. The compact metallic bellows of the present invention is particularly adapted for fitting into a small space and taking advantage of its equal free length and solid length to provide a spring force equal the sum of the spring force of each of the several metallic diaphragms.
