1. Argon arc welding is a welding technology that uses argon as a protective gas. Also called 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 oxidation of the welding area. Argon arc welding technology is based on the principle of ordinary arc welding, using argon gas to protect metal welding materials, and using high current to melt the welding materials into a liquid state on the base material to be welded to form a molten pool, so that the metal to be welded and the welding material are A welding technology that achieves metallurgical bonding of materials. Since argon gas is continuously supplied during high-temperature molten welding, the welding material cannot come into contact with oxygen in the air, thus preventing the oxidation of the welding material. Therefore, stainless steel and iron hardware metals can be welded.
2. Welding rod 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 with each other and form a weld after condensation, thereby obtaining a strong joint. welding process. 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 tool equipment, etc.
3. From an economic point of view and flexibility, arc welding is better. In terms of efficiency, of course, argon arc welding is higher, has better effects, and is more mechanized. If it is a small batch, arc welding will be chosen.
4. The quality of argon arc welding is high, but the efficiency is low. The efficiency of electrode arc welding is relatively high, but the quality is medium. Generally, thick pipe fittings such as 10mm are welded by argon arc welding as the base, and the electrode fills the cover. If the pipe fittings are thin, just directly Use argon arc welding.
