Abstract
From 1980 to 1993 DREA Dockyard Laboratory supported an extensive research program in welding processes for HY steels. This program was begun in long term anticipation of the Canadian Navy replacing the Oberon submarines and the need for extensive Canadian knowledge in fabrication and inspection with HY steels. In later years this program has found more immediate application in questions related to extension of Oberon life, ie cladding, mismatched steels, electrode substitution and certification etc. The welding program has included many types of welding, all position, numerous equipment and consumable types, different gases, a range ofheat inputs etc. Several novel Canadian processes have been explored in addition to traditional welding methods. After considerable welding and evaluations, numerous procedures have been developed using different processes, and an optimized pulsed GMAW process has been identified that provides properties approaching those of HY steels.
