Technical Field
The utility model relates to the field of welding technique, especially indicate a cooling frock is used in welding.
Background
Tungsten Inert Gas (TIG) welding is a welding method in which a base metal and a filler wire are melted (or no filler wire is added) by an arc generated between a tungsten electrode and a workpiece to form a weld. The welding quality is good, the argon is inert gas, the argon does not react with metal chemically, alloy elements are not oxidized and burnt, and the argon is not dissolved in the metal. The welding process is basically a simple process of metal melting and crystallization, so the protection effect is good, and a high-quality welding line can be obtained. The weldable metal material has various types, except that argon can effectively isolate the air around a welding area from reacting with metal, and electric arc has the function of automatically removing an oxide film on the surface of a weldment in the TIG welding process. Therefore, non-ferrous metals, stainless steels and various alloys which are difficult to weld, easy to oxidize, nitridize and chemically active by other welding methods can be successfully welded. The adaptability is strong, the tungsten electrode arc is stable, and the combustion can be stable even under a small welding current; no splash is generated, and the weld joint is attractive in shape; the heat source and the welding wire can be respectively controlled, so that the heat input quantity is easy to adjust, and the welding wire is particularly suitable for welding thin parts and ultrathin parts; can weld at various positions, and is easy to realize mechanization and automation. However, when welding a material with better thermal conductivity, such as an aluminum alloy part, the heat generated during welding may cause the strength of the welded joint to decrease, and usually, the strength of the material near the welded joint may decrease by 30% to 40%.
Disclosure of Invention
To not enough among the above-mentioned background art, the utility model provides a welding is with cooling frock has solved the problem that the heat when welding can cause welded joint's intensity to reduce among the prior art.
The technical scheme of the utility model is realized like this:
a cooling tool for welding comprises a cooling workpiece arranged on a welded joint, wherein a cooling water cavity is arranged in the cooling workpiece, and the cooling water cavity is connected with a circulating water pipeline.
