Abstract: Superalloy components are joined or repaired by mating a recess formed in one component substrate with a corresponding projection formed in another component along a contact surface and welding them together with a stud welding apparatus. A mating superalloy repair stud is formed with a stud projection whose profile conforms to the substrate recess profile along a corresponding contact surface. Both the stud and substrate are coupled to a stud welding apparatus, with the stud projection and substrate recess oriented in an opposed spaced relationship with a gap there between. The stud welding apparatus passes current between the stud projection and recess and forms an arc there between, to melt their respective opposed surfaces. The melted stud projection and substrate recess opposed surfaces are pressed into contact with each other with the stud welding apparatus, forming a weld there between.

Abstract: A billet includes a solid steel body and an alloy cladding. The cladding may include a square tube in which the body is inserted with an interface at which the cladding becomes bonded to the body when the billet is heated and rolled or otherwise worked into a ferrous product. At least one element composed of a mass of finely divided scavenging aluminum, titanium or magnesium, is placed in the tube adjacent the body and separate from the interface. The elements are advantageously compressed into briquettes which scavenge oxygen from residual air at the interface to prevent oxidation of the cladding at the interface. The tube may be closed to prevent gases outside the billet from penetrating to the interface. Alternatively, reliance may be placed on the briquettes to scavenge oxygen from the residual air and also from atmospheric air and furnace gases before they can penetrate to the interface.
