Abstract

The invention relates to a CoTIG welding gun capable of compressing an electric arc and a welding method. The welding gun is hereinafter referred to as CoTIG. The welding gun comprises a gun body and a hollow tungsten electrode, wherein the front end of the gun body is longitudinally connected with a nozzle movably; a through hole is longitudinally formed in the middle of the gun body; the hollow tungsten electrode is fixedly arranged in the through hole; the front end of the hollow tungsten electrode penetrates out of the nozzle; a welding wire hole is longitudinally formed in the middle of the hollow tungsten electrode in a penetrating manner; a cooling channel is formed inside the nozzle; and two ends of the cooling channel respectively communicate with a water inlet tube and a water outlet tube. On the basis of a HiTIG welding gun, the welding efficiency is improved, and welded joint quality of welding is optimized. Electric arc compressing modes are integrated, existing single-action electric arc compression is changed, double electric arc compression is realized, the CoTIG welding gun has great progress on the thicknesses of welding base materials, thick plates can be welded, and the CoTIG welding gun can also be used for welding machining of large plates.

Description

technical field [0001] The invention belongs to the technical field of TIG welding, in particular to a CoTIG ​​welding torch with compressible arc and a welding method. Background technique [0002] TIG welding (Tungsten Inert Gas Welding), also known as non-melting inert gas tungsten shielded welding. Due to the protection of argon, it can isolate the oxidation of molten metal by air. Therefore, TIG welding is widely used for welding non-ferrous metals such as aluminum, magnesium and their alloys, stainless steel, high-temperature alloys, titanium and titanium alloys that are easily oxidized. Molten active metals (such as molybdenum, niobium, zirconium, etc.), and common materials such as carbon steel and low alloy steel, generally do not use TIG welding except for occasions that require high welding quality. However, TIG welding has problems such as shallow penetration, low deposition rate, and relatively low production efficiency. [0003] Coaxial hot wire TIG welding (...
