Benefits of technology

This patented technology improves on melting elec trongetic wire for use in electric resistance spot welds by reducing variations during manufacturing processes that can affect their final product' characteristics such as size or thickness. By increasing its precision and consistently achieving this results in lower costs compared with traditional methods like laser beam machining (LM).

Problems solved by technology

This patented describes different methods called Three Dimensional Printing with Metal Layers, which are described as techniques for creating complex objects quickly without requiring expensive equipment like Laser Interference Melter(LIMM)). However, there have limitations when applying these processes due to their slow process speeds and complicated support systems required during implementation.

Abstract

The invention discloses a consumable electrode gas shielded arc deposition three-dimensional printing method. The method comprises the following steps: (1) a metal component three-dimensional digital model is designed in three-dimensional software; three-dimensional printing system software is adopted to slice the three-dimensional digital model to generate multiple two-dimensional data piece layers; and a processing path is formed through analysis; (2) single layer of metal components are molded through deposition by a welding gun according to the processing path; and in the welding gun, the fuse diameter is 0.08-1.5 mm, the welding voltage is 14-20 V, the welding current is 2-20 A, the wire walking speed is 1-12 mm.s-1, the wire feeding speed is 0.5-15 mm.s-1, and the shielded gas pressure is 2-5 Mpa; and (3) after deposition molding of the single layer of metal components, a three-dimensional control platform automatically adjusts a gap between the welding gun and a newest generated surface; and the three-dimensional deposition molding of the metal components is finished after multiple times of circulation. The three-dimensional metal components, molded by the method through deposition, improve the shape precision and the surface quality, and improve the metallographic structures and the uniformity; and in addition, the method has the advantages of low cost and high deposition rate.
