A jack assembly is provided in which the central body of the assembly includes integrally cast posts for aligning and securing follower springs, wiper springs and spacers. To assemble the jack, the follower springs, wiper springs and spacers are stacked onto the posts and then secured with a pushnut that engages the posts with a friction fit, avoiding separation from the central body.

A laser welding system is disclosed having a housing formed with an opening through which workpieces may be passed, and a laser for generating and directing a laser beam into a welding station within the housing. The system further includes a light trap for inhibiting light from passing from the welding station through the housing opening to the exterior to the housing and a conveyor for conveying workpieces between workpieces loading and unloading stations located exteriorly of the housing and the welding station through the housing opening and the light trap. A method of laser welding a succession of workpieces is also disclosed comprising the steps of successively loading workpieces onto a conveyor at a loading station and conveying the workpieces through a light trap to a welding station located within a housing. The workpieces are illuminated with laser radiation at the welding station and then conveyed through a light trap out of the housing to an unloading station where they are unloaded.
