A new group of moisture resistant E7018MR electrodes have been developed that substantially reduce the risk of exceeding U.S. Naval and military moisture requirements for welding electrodes. They also substantially reduce costs of welding repairs. The electrodes are produced in two qualities: one for regular use and the other for critical code work, produced to meet all AWS, ASME, and MIL specifications. Ingalls Shipbuilding division of Litton Industries in Pasacgoula, Mississippi is one shipyard using the new electrodes. The yard is at present building two new classes of ship for the Navy: the advanced class of DD-963 multi-mission destroyers and the LHA general-purpose amphibious assault ships. All electrodes are rebaked in carefully calibrated baking ovens before being issued to the welders. This is particularly important for submarine hulls. These electrodes are used for welding HSLA steels with yield strength up to 100,000 lb/sq in.
