ABSTRACT:
A light-gauge metal container has a closure flange fixed to a container wall, to which a closure plug is detachably screwed. An inwardly projecting cylindrical neck is fastened to the edge of a closure flange receiving opening made in the container wall. The closure flange is inserted in the opening so that the inward ends of the flange and neck flushed with each other, with an annular face formed by the flushed flange and neck ends circularly edge-welded. In manufacturing the container, the closure flange is press-fitted in the receiving opening, with the annular face held in the horizontal position. The assembly is transferred to welding apparatus, and positioned roughly first, then exactly by mating the flange opening with a vertical reference shaft on the welding apparatus. The annular face is edge-welded by rotating a welding torch about the axis of the reference shaft.
