ABSTRACT:
The stress corrosion tendency of a welded pipe in service in a nuclear reactor water line is reduced by applying to the outside of the pipe a secondary weld bridging the primary weld of the joint beyond the axial extremities of the primary weld heat affected zone and particularly that part of the zone at the inner surface of the pipe.
