Abstract

The invention relates to the technical field of welding wires, and particularly discloses a stranded welding wire for automatic TIG. The stranded welding wire for automatic TIG comprises a middle wire, peripheral thick wires and peripheral stranded wires, wherein the stranded welding wire is formed by twisting the one middle wire, the three peripheral thick wires and the three peripheral strandedwires, and the intervals of the middle wire, the peripheral thick wires and the peripheral stranded wires are filled with active agents. According to the stranded welding wire for automatic TIG, complex production procedures such as melting, heat treatment, extrusion, wire drawing and the like are not needed, the product is formed by stranding and twisting, the production period is short, the costis low, and the efficiency is high.

Description

technical field [0001] The invention relates to the field of welding wire technology, in particular to a stranded welding wire for automatic TIG. 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 strips, fluxes, solders, etc. With the continuous improvement of the level of welding automation in my country, the amount of welding wire that can adapt to automated welding is increasing rapidly. Improving the welding productivity of metal arc welding is an important aspect to promote the development of welding technology, and increasing the welding deposition rate is an important measure to improve welding productivity. The size of the wire diameter is an important factor in the welding deposition rate. As a welding wire, it is required to have a certai...
