Under what circumstances can stainless steel pipe fittings be welded with argon arc welding, and under what circumstances can electric arc welding be used

1. Argon arc welding is a welding technology that uses argon as a shielding gas. It is also called argon gas-shielded welding. It is to pass argon shielding gas around the arc welding to isolate the air outside the welding area to prevent oxidation of the welding area. Argon arc welding technology is based on the principle of ordinary arc welding. It uses argon gas to protect metal welding materials. Through high current, the welding materials are melted into liquid on the welded substrate to form a molten pool, so that the welded metal and welding materials can achieve metallurgical bonding. Since argon gas is continuously supplied during high-temperature molten welding, the welding materials cannot contact the oxygen in the air, thereby preventing the oxidation of the welding materials. Therefore, stainless steel and iron hardware 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 welding rod and the workpiece together and form a weld after condensation, thereby obtaining a welding process with a firm joint. Arc welding has a wide range of applications, such as excavator bucket teeth, loader blades, bulldozer blades, crushers, screw conveyors, mixer blades, railway tracks, forging hammers, transmission gear rims, various molds, slag crushers, ball mills, machine tools, etc.

3. From an economic point of view and flexibility, arc welding is better. From the perspective of efficiency, argon arc welding is of course higher, with better results and more mechanization. If it is a small batch, arc welding will be chosen.

4. Argon arc welding has high quality and low efficiency. Electrode arc welding has relatively high efficiency and medium quality. Generally, thick pipes such as 10mm are welded with argon arc welding as the base and electrodes are filled and covered. If the pipes are relatively thin, argon arc welding is used directly.
