1. The main welding machines used by industrial and mining enterprises are: AC arc welding machine, DC welding machine, argon arc welding machine, carbon dioxide shielded welding machine, butt welding machine, spot welding machine, submerged arc welding machine, high frequency welding seam machine, flash butt welding machine, press welding machine, touch welding machine laser welding machine.

The main difference between the application areas of the AC welder and the DC welder is that the AC welder is generally used in steel manufacturing units or general general machinery or agricultural machinery manufacturing units. The DC welder is mainly used in the manufacture of pressure vessels, boilers, pipes or important structural manufacturing units for welding.

(1) The main application areas of inverter welding machines are the same, except that they are more energy efficient and lighter.

(2) The main application areas of the submerged arc welding machine are large steel fabrication units and pressure vessel boiler fabrication units.

(3) The main application areas of the gas shielded welding machine are large steel structure manufacturing units or general machinery agricultural machinery, automobile manufacturing plants, security door processing plants, manufacturing pressure vessel boiler units are now also widely used in the gas shielded welding machine.

(4) Argon arc welding machines are mainly used in pipelines, pressure vessels boilers, stainless steel processing enterprises.

(5) AC argon arc welding machine is mainly used in aluminium welding manufacturing units, aluminium vessel manufacturing units. Aluminum heating plate welding.

2. There are two kinds of DC welding machines: one is based on the AC motor with rectification elements, and another is a DC generator. DC welding machine mainly welding non-ferrous metals, pig iron mainly. The AC welding machine mainly welds steel plates.

3. Argon arc welding machine, carbon dioxide shielded welding machine, high frequency fung welding machine, flash butt welding machine. Argon arc welding machine, carbon dioxide gas shielded welding machine can mainly weld 2MM below the thin plate and non-ferrous gold layer. Flash butt welding machine mainly butt copper and aluminium joints and other objects, high-frequency welding machine mainly pipe factory welding steel pipe.

4. Submerged arc welding mainly welds steel structure parts, bridge H steel, I-beam house beams and other thick steel structure materials.

5. Gas shielded welding machine: argon arc welding, carbon dioxide shielded welding, under the protection of gas welding machine will not oxidize, soluble welding firm, can be welded colored gold layer, can be welded thin materials.

6. Laser welding machine: can weld the lead inside the transistor.

7. Butt welding machine: the main welding anchor on the iron rope and other objects in the cable chain factory. It can butt weld meta steel, etc.
