Abstract
A plasma arc spray overlay of cladding metals is used over joints between clad metal pieces to provide a continuous cladding metal surface. The technique permits applying an overlay of a high melting point cladding metal to a cladding metal surface without excessive heating of the backing metal.
Claims8
A clad metal joint closure in which clad metal members having a cladding metal surface layer and a backing metal layer are joined by a fusion weld joining opposing portions of the backing layers, and having an impervious plasma arc spray overlay over the joint between the cladding metal surface layers and extending for a short distance over the adjacent portions of the cladding metal layers and bonded thereto.
A clad metal closure joint in which clad metal members are joined which have a very high melting cladding metal surface layer, a heat dissipating inner layer, and a structural backing metal layer, in which the backing metal layers are fusion welded together, a filler strip with a cladding metal outer surface is over the fusion weld and between the edges of the cladding and inner layers of the clad metal members and welded by attaching welds to the edges of the cladding metal layer;
- and the filler strip, attaching welds and adjacent portions of the cladding metal surface are covered by a plasma arc spray overlay.
