Abstract
The construction of SSK Upholder class submarines is an important issue for the Canadian Navy now that the four vessels are to be transferred, beginning in the year 2000, from the United Kingdom to Canada. This is because an understanding of the fabrication methods will generate confidence in the integrity of the hull envelope and will directly assist the Canadian Navy when it becomes necessary to carry out future repair and refits. This paper describes the materials and methods of construction used in the fabrication of the ull envelope by people who were involved in the qualification of the weld procedures and one who was directly involved in the construction of this class of submarine. The paper records a number of new developments in welding, related to construction issues, which may have a role to play in future submarine maintenance.
