(EN) Hybrid laser plus submerged arc or electroslag cladding of superalloys

Abstract
(EN)

A method for cladding of superalloy materials. A layer of powder (14) disposed over a superalloy substrate (12) is heated with an energy beam (16) to form a layer of superalloy cladding (10) and an overlying layer of slag (18). A filler material (44) of nickel, nickel-chromium or nickel-chromium-cobalt wire or strip is also added to the melt pool to combine with the melted powder via a submerged arc or electroslag heating process to give the superalloy cladding the composition of a desired superalloy material. The layer of powder includes a layer of powdered flux material (22) over a layer of powdered metal (20), or the flux and metal powders may be mixed together (36).
