Description
Technical Field
The invention relates to the technical field of pipeline welding, in particular to a self-moving pipeline welding gas storage device.
Background
The argon arc welding technology is a welding technology which utilizes the protection of argon gas on metal welding materials on the basis of the principle of common electric arc welding, melts the welding materials into liquid on a welded base material through high current to form a molten pool, and enables the welded metal and the welding materials to be metallurgically combined. Because argon is continuously fed in the high-temperature fusion welding process, the welding material cannot be contacted with oxygen in the air, thereby preventing the oxidation of the welding material, and the argon is commonly used for welding stainless steel, iron metals and the like.
Stainless steel is widely used in various aspects of production and life because of its good chemical stability in air, water, acid, alkali or salt aqueous solutions. For example, a stainless steel lined pipe having advantages of high strength, high corrosion resistance, low cost, long service life, etc., which is useful as a fire fighting pipeline, etc., may be formed from a base pipe (e.g., a seamless steel pipe) and a stainless steel liner. However, during the welding process of the stainless steel lined pipe, the stainless steel liner pipe on the inner side is oxidized by contacting with the air in the pipe, and the welding quality is seriously affected. For this reason, the inner stainless steel pipe is usually protected by welding by filling the pipe with argon gas. However, the method of directly filling the argon gas into the pipe (particularly, the long pipe) requires a large amount of argon gas, thereby increasing the production cost.
