Abstract
There is described a method of joining a first metallic structural member, which comprises a metallic member having a coating of a heat-degradable material on one surface thereof, to a second metallic structural member which comprises a metallic member, along abutting edges by forming a welded joint between the abutting metal edges of the metallic members in which method the metallic member and the coating of the first structural member are separated along that edge of the first structural member which is to be welded to the second structural member by a heat shield which substantially prevents heat being transferred from the welded joint, during the formation thereof, to the coating.
