Webweld away from the split allowing the heat of the molten metal to expand the ring tightly against the inner surface of the pipe. This eliminated gaps, openings or crevices between the backing ring and the pipe. The engineered concavity across the surface of the S-40000 BACKING RING permits weld shrinkage and prevents curling-of the ring edges.
