Abstract
The invention discloses a bimetal cladding additive manufacturing method in the field of manufacturing technology, which includes the following steps: (1) preparation of program code; (2) welding preparation; (3) start of surfacing; (4) stop of surfacing (5) surfacing welding of supporting structure; (6) return to step (3) until the last layer of surfacing welding of supporting structure is completed; (7) surfacing welding of the last layer of surfacing layer of formed parts; (8) remove Base, put the formed part into the heating furnace; (9) Set the heating temperature of the heating furnace; (10) Heat the part in the heating furnace to completely melt the supporting structure; (11) Close the heating furnace, and take out the formed part after the part is cooled ; The present invention can perfectly manufacture parts with suspended structures, and the manufacturing efficiency is high.
Description
Technical field [0001] The invention relates to an additive manufacturing method, in particular to a manufacturing method using bimetallic welding wire for additive manufacturing. Background technique [0002] At present, the main additive manufacturing technologies that can be used to directly manufacture metal parts are: selective laser sintering technology, direct metal powder laser sintering technology, selective laser melting technology, laser near net shaping technology and electron beam selective melting technology. The current metal additive manufacturing technology uses various metal powders. At present, austenitic stainless steel, nickel-based alloys, titanium-based alloys, cobalt-chromium alloys and various precious metals have been widely used in metal additive manufacturing. , The use of metal powder as a material for additive manufacturing has better shape control capabilities and freedom of shaping. This metal powder is extremely difficult to prepare, often difficu...
