Embodiment

[0119] Taking the arc additive manufacturing of bimetallic composite pipe Φ60mm×(10+2.5)mm×80mm L360 / 625 as an example, such as image 3 As shown, the specific implementation steps of bimetallic composite arc additive manufacturing are illustrated:

[0120] H08C welding wire is selected as the welding wire for arc welding additive base material manufacturing, and the diameter of the welding wire is 1.2mm.

[0121] The arc welding additive cladding wire is selected from UNS N06625 (ERNiCrMo-3), and the wire diameter is 1.2mm.

[0122] 1. 3D modeling: First, the 3D drawing software is used to model the bimetal composite workpiece model. Material A is carbon steel material, and material B is 625 alloy material;

[0123] 2. Layered slicing: First, the 3D model is layered and sliced, and the thickness of the layered slice is calculated and determined according to the accuracy requirements of the part drawing. The thickness of each layer is selected to be 2.5mm, and the layered lay...

Abstract

The invention discloses a bimetal composite electric arc additive manufacturing device and a manufacturing method thereof. The bimetal composite electric arc additive manufacturing device is composedof a control system part and a mechanical part; the bimetal composite electric arc additive manufacturing method finishes the whole bimetal composite electric arc additive manufacturing through 3D model modeling, layer-by-layer slicing, data processing, tool alignment, wire feeding starting, gas protection starting, material electric arc power source starting, electric arc striking, 3D motion, andelectric arc tracing. Additive manufacturing of two metal composites can be achieved, the process flow is short, the input equipment is little, the needed site is small, and the device and method aresuitable for batched production.

Description

technical field [0001] The invention belongs to the technical field of additive manufacturing 3D printing, and relates to a bimetal composite material arc additive manufacturing device and a manufacturing method thereof. Background technique [0002] In the field of additive manufacturing 3D printing, arc additive manufacturing has the advantages of faster wire feeding and faster metal cladding deposition than laser-selected powder additive manufacturing, and is suitable for the manufacture of large products and workpieces. [0003] The existing additive manufacturing technology is only single-material manufacturing, that is, one-material additive manufacturing, and bimetal composite material additive manufacturing has not yet been realized. Due to bimetallic composite materials, such as carbon steel / stainless steel composite materials, carbon steel materials can achieve load and strength effects for the workpiece structure, and stainless steel materials provide corrosion re...
