Abstract
Apparatus for welding and testing a weld on a cover for a container for radioactive material. Two carriages are mounted on a bridge extending across and above the container. Gas shielded arc welders are mounted on the carriages. The carriages move across the bridge to accurately locate the welder with respect to the joint being welded. The container is mounted on a rotating platform to move the weld area past the welder and the test devices which are fixed when in working position.
