Abstract

The invention belongs to the technical field of additive manufacturing, and relates to a low-energy-consumption heterogeneous multi-wire pre-melting-TIG additive manufacturing method, an electric arc additive manufacturing system 3D printing system is adopted for forming manufacturing, a plurality of wire feeding units are arranged in the electric arc additive manufacturing system 3D printing system, and welding wires on the wire feeding units are made of different materials; a preheating system is arranged in a 3D printing system of the electric arc additive manufacturing system, a welding wire is preheated through the preheating system to be used for supplementing melting energy difference values needed by welding wires made of different materials under the same forming current in a differentiated mode, and then 3D printing is conducted through a TIG welding gun. According to the method, energy differentiation treatment of welding wires made of different materials is achieved by accurately controlling preheating, the arc current in the forming process is reduced, energy consumption is reduced, low-energy-consumption additive manufacturing of multiple materials under the same arc is achieved while the forming speed is increased, and heterogeneous material components with uniform components are obtained.

Description

technical field [0001] The invention belongs to the technical field of additive manufacturing, and relates to a low-energy heterogeneous multi-filament premelting-TIG additive manufacturing method. Background technique [0002] Blade-like metal parts with large torsion angles are a type of typical structural parts, which are widely used in the engineering field. Because of their complex working conditions, the performance requirements are constantly improving. In engineering, the combined manufacturing design of heterogeneous materials is continuously used to improve the performance of structural parts and meet the needs of extreme working conditions, but it is very difficult to combine different materials into a single product, which leads to the processing of traditional processing methods (casting, forging, etc.) Problems such as long cycle time and high manufacturing cost. [0003] The high-energy-density heat source (laser, arc, electron beam) used in metal additive ma...
