Abstract
An assembly of top and bottom plates spaced apart vertically by peripheral and intermediate spacer bars forming a shelf of freeze drying or other processing equipment, is held together on a movable base support by peripheral clamps mounted removably at selected positions on the base support. A hollow framework carriage is mounted on the base support for movement above and relative to the shelf assembly and it supports a pair of elongated, laterally spaced clamp bars for retractable movement toward and away from the base support for releasably clamping therebetween interposed portions of the shelf assembly. A laser welder then is moved relative to the clamp assembly to weld the components together in the clamped areas. Upon completion of the welding operation, the clamp bars are retracted and the framework moved over the base support and assembly to the area next to be welded, whereupon the clamp bars are extended into clamping position and the welding operation is repeated.
