Abstract

The invention relates to the technical field of welding wires, and specifically discloses a multi-strand stranded welding wire for a 3D printing wire material. The multi-strand stranded welding wire comprises a carbon dioxide storage tube, peripheral coarse wires and peripheral fixed stranded wires, wherein the number of the peripheral coarse wires is four, the number of the peripheral fixed stranded wires is four, the peripheral coarse wires are twisted on the carbon dioxide storage tube in a cross shape, the four peripheral fixed stranded wires are correspondingly positioned at gaps betweenthe peripheral coarse wires, the peripheral fixed twisted wires are stranded with the peripheral coarse wires, and the carbon dioxide storage tube is of a multi-section structure. According to the multi-strand stranded welding wire, carbon dioxide can be released during welding by adopting the carbon dioxide storage tube, so that a protection zone is formed at the welding position, high-temperature oxidation of a welding part is reduced, and the stranded stability and high deposition rate are realized by adopting the four peripheral coarse wires and the peripheral fixed stranded wires.

Description

technical field [0001] The invention relates to the technical field of welding wires, in particular to a 3D printing wire multi-strand stranded welding wire. Background technique [0002] As an important material processing technology, welding technology is widely used in machinery manufacturing, petrochemical, shipbuilding, bridge, aerospace and other industries. Welding materials mainly include welding rods, welding wires, welding ribbons, fluxes, solders, etc. With the continuous improvement of the level of welding automation in my country, the amount of welding rods that can adapt to automated welding rods has increased rapidly. Improving the welding productivity of metal arc welding is an important aspect to promote the development of welding technology, and improving the welding deposition rate is an important measure to improve the welding productivity. [0003] When the existing welding wire is welded, the high temperature environment is easy to cause oxidation, the...
