Under what circumstances should argon arc welding be used for stainless steel pipe fittings, and under what circumstances can arc welding be used

Many people, do not know under what circumstances stainless steel pipe fittings need to be selected for welding technology, so the next step is to look at it step by step to facilitate the selection of welding technology in the future.

1. Argon arc welding is a welding technology that uses argon gas as a protective gas. Also known as argon gas-shielded welding. It is to pass argon protective gas around the arc welding to isolate the air from the welding area and prevent the oxidation of the welding area. The argon arc welding technology is based on the principle of ordinary arc welding, using argon gas to protect the metal welding material, and through high current, the welding material is melted into a liquid state on the substrate to be welded to form a molten pool, so that the metal to be welded and the welding material is formed. It is a welding technology in which the metallurgical combination of materials is achieved. Due to the continuous supply of argon gas during high-temperature fusion welding, the welding material cannot be contacted with oxygen in the air, thereby preventing the oxidation of the welding material. Therefore, stainless steel and iron metal metals can be welded.

2. Electrode arc welding is the most widely used welding method in industrial production. Its principle is to use the heat generated by arc discharge (commonly known as arc combustion) to melt the electrode and the workpiece and form a weld after condensation, to obtain a solid joint. welding process. Arc welding has a wide range of applications, such as excavator bucket teeth, loader blade blades, bulldozer blades, crushers, screw conveyors, mixer blades, railway tracks, forging hammers, rims of transmission gears, various molds, Slag crushers, ball mill, machine tool equipment, etc.

3. From the economic point of view and flexibility, arc welding is good. Of course, argon arc welding has high efficiency, a better effect, and more mechanization. If it is a small batch, arc welding will be selected.

4. The quality of argon arc welding is high and the efficiency is low. The efficiency of electrode arc welding is relatively high and the quality is medium. Generally, the thickness of the pipe fittings, such as 10mm, is made by argon arc welding, and the electrode fills the cover. If the pipe fittings are relatively thin, directly Use argon arc welding.
