Abstract

The invention discloses an MIG-TIG composite material adding device. The device comprises an MIG welding robot, a TIG welding robot, a workbench, a base plate water chilling device, a CCD camera, an infrared thermometer and a computer. The computer is connected with a TIG material adding robot, an MIG material adding robot, the CCD camera and the infrared thermometer, and controls the whole composite material adding device cooperatively. A base plate is placed in the water chilling device, the temperature of the base plate is controlled, and thermal deformation of the base plate is reduced. The device fully combines the advantages of two material adding devices, and material adding precision is also improved while the material adding efficiency is improved. Therefore, high efficiency and high precision electric arc additive manufacturing is achieved.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to a MIG-TIG composite additive device. Background technique [0002] Additive manufacturing technology is a technology based on CAD / CAM design, which uses a layer-by-layer accumulation method to manufacture solid parts. Compared with traditional subtractive manufacturing (cutting) technology, it is a manufacturing method of material accumulation. The heat sources generally used in the material manufacturing process include high-energy beams and electric arcs. [0003] The arc additive manufacturing technology mainly uses the welding arc as the heat source, and the metal welding wire as the additive material. The heat generated by the arc melts the welding wire, and then accumulates layers from bottom to top on the selected substrate according to the preset additive path until it is completed. Additive manufacturing. According to the heat source classification, arc ...
