Abstract : To evaluate weldments made with commercially available welding materials and relatively low welding-heat input, the Mare Island Naval Shipyard prepared submerged-arc weldments for explosion-bulge testing. For comparison purposes MINSY also submitted production-welded specimen weldments prepared by manual metal-arc (Mil-26015 and Mil-11018 electrodes) and inert-gas-shielded metal-arc (Mil-B-88 electrode) welding processes. Test results of six 2-in. thick manual metal-arc (Mil-11018) weldments fabricated by Industrial Testing Laboratory and tested at Naval Proving Ground were also included. These and two automatic submerged-arc welded samples which were laboratory-prepared by an industrial company were tested by explosion-bulge and Charpy V impact test procedures.
