Explosion-bulge tests were conducted at 0 F to evaluate the performance of machine welded HY-80 steel intended for submarine hull construction. Three types of welding methods were used to produce the weldments: (1) inert-gas-shielded metal-arc (Code C); (2) submerged arc (Code D); (3) submerged arc (Code E). The performance of automatic weldments involving inert-gas-shielded metal-arc processes were shown to be satisfactory for applications based on 'military service' loading conditions. Automatic weldments involving submerged arc processes (Code B and Code C) were characterized by high birtleness at 0 F of either the weld or HAZ. At their present state of development, submerged arc processes are not considered suitable for HY-80 applications based on 'military service' loading conditions.
