Title:
ELECTRIC MELTING METHOD FOR FORMING METAL STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2016/070778
Kind Code:
A1
Abstract:
An electric melting method for forming a metal structure. The method: an electric melting head (6) and a substrate (2) respectively are connected to either electrode of a power source (12), when forming, a raw material metal wire (1) is fed to a surface of the substrate (2) via a wire feeder mechanism (5) and the electric melting head (6), under the protection of a stack of a granular auxiliary material (3), an electric arc (9) is produced between the raw material wire (1) and the substrate (2) to partly melt the surfacing auxiliary material (3) to form a molten slag pool (8), an electric current flows through the raw material wire (1) and the molten slag pool (8) to form resistance heat and electroslag heat, the raw material wire (1) is molten under the effect of a high-energy heat source combining the electric arc heat, the resistance heat, the electroslag heat, a partly molten pool (11) is formed on the surface of the substrate (2), conveyance of the raw material wire (1) and the auxiliary material (3) is continued, a computer is employed to control relative movements of the electric melting head (6) and of the substrate (2) on the basis of layer slicing data of a forming component, rapid cooling and layer-by-layer solidification and deposition of the molten pool (11) on the substrate (2) is implemented, and finally, the metal structure of a required shape and dimensions is formed by layer-by-layer deposition.
