There is provided a process for brazing a first coated part to a second metal part which includes the steps of cleaning or masking, the surfaces of at least the first metal part, interposing a brazing metal foil between the metal parts, and induction heating the assembly to fuse the brazing metal foil, whereby the parts are adhered together, and then cooling. A controlled heating profile is disclosed.

A process for adhering an at least partially coated and catalyzed first metal body to a second betal body which comprises the steps of (a) providing at least one first metal body having a coating of refractory metal oxide and a catalyst supported thereon and having at least one uncoated joint area to be adhered to said second metal; (b) applying a fusible brazing metal to said joint area to be adhered to said second metal, said brazing metal having a predetermined fusion temperature; (c) retaining said first and second metal bodies against relative movement to provide an assembly; (d) placing said assembly within the coils of an induction heater; (e) applying electrical power to said induction heater to raise the temperature in said joint area to an intermediate temperature below said predetermined fusion temperature and holding for a period of about 15 seconds and thereafter raising the temperature to said predetermined fusion temperature to fuse said brazing metal; (f) upon reaching the predetermined fusion temperature immediately terminating the application of power; and (g) cooling said assembly to effect adhesion of said first metal body to said second metal body.
