ABSTRACT OF THE DISCLOSURE This invention relates to a method of providing imper- vious closure joints for clad metals which comprises welding abutting portions of the backing metal layer of pieces of clad metals characterized by applying an impervious coating over the joint between the pieces and over adjacent portions of the sur- face of the cladding metal layer of such pieces by plasma arc spray. A clad metal joint is also provided in which clad metal members having a cladding metal surface layer and a backing metal layer are joined by a fusion weld joining opposing por- tions of the backing layers. The joint has an impervious plas- ma arc spray overlay thereover between the cladding metal sur- face layers and which extends for a short distance over the adjacent portions of the cladding metal layers and which is bonded thereto. The invention provides an advance in the art over known clad metal joint closures. More specifically, the technique of this invention permits applying an overlay of a higher melting point cladding metal to a backing metal surface of a lower melting point without excessive heating of the back- ing metal. The invention is useful in the production of clad vessels for the chemical process industry.
