ABSTRACT:
In the preferred embodiment, a method is presented for filling depressions in fabricated steel surfaces by applying a metallic body solder consisting of 15 to 20 weight percent copper, 2 to 3 weight percent zinc and the balance tin. The body solder alloy is heated to a temperature above about 210.degree. C. to form a workable thixotropic paste that is applied with spreading onto the steel surface. Upon cooling, the body solder forms a dense, tightly adherent fill that is grindable and paintable in conjunction with the surrounding steel surface.
