Description
Technical Field
The present invention relates to a weld metal material, and more particularly, to a metal composition for welding and an alloy obtained from the metal composition.
Background
In the past half century, the fusion of laser technology, computer technology and new material technology has led to a new era of additive manufacturing (3D printing) technology. The additive manufacturing is a direct near-net forming technology without a mold, and is based on computer aided design/manufacturing, materials are solidified and clad layer by layer or stacked layer by layer and connected into an integral structure by block assembly welding, so that a personalized, customized and miniaturized production mode can be realized.
In terms of the physical concept of machining and manufacturing, welding is a typical example of additive manufacturing, and both a welding rod repair surfacing technology and a numerical control automatic welding technology and additive manufacturing based on a high-energy beam heat source belong to the field of generalized additive manufacturing. The technology basis for the rapid development of the additive manufacturing technology of metal components is the technical progress of taking high-energy beams (electron beams and laser beams) as special welding heat sources, the high-energy beams are very flexible, the energy can be accurately controlled, the high-energy beams are deeply fused with computer-aided design/manufacturing information technology, and metal wires or metal powder is filled into a focusing heating area or paved into the focusing heating area in a vacuum chamber or in an inert gas protection environment, so that the materials are melted and solidified and formed layer by layer.
The additive manufacturing essentially belongs to the field of material processing, commonly used additive manufacturing materials (consumables) comprise engineering plastics, rubber materials, photosensitive resin, metal, ceramic and the like, wherein the 3D printing technology of the metal materials is developed rapidly, and metal powder used in 3D printing generally requires high purity, good sphericity, narrow particle size distribution and low oxygen content. At present, the metal powder materials applied to 3D printing mainly include titanium alloys, cobalt-chromium alloys, stainless steel, aluminum alloy materials, and the like.
At present, the additive manufacturing of China already has some influential enterprises and brands in the fields of equipment, software and the like, but materials mainly depend on import, and the research and development of additive manufacturing materials with independent intellectual property rights have important significance.
