CLAMPING AND WELDING ASSEMBLY

摘要

An orbital tube welder is provided comprising a pair of tube clamping assemblies having dual clamping areas and an electrode carrying housing adapted for rotation around the clamping assemblies while applying a closing force thereon. The clamping assemblies advantageously accommodate irregular contours along the length of tubing being welded while assuring precise positioning and secure aligned clamping thereof during the welding operation by utilizing clamping jaws adjacent the weld and a spaced resilient aligning and clamping collar having a radial slot extending along the length thereof. Multiple adjustments are incorporated in both the housing and the individual clamping assemblies for precisely controlling alignment of the tubes being welded.
