Common welding machine types

1. The main welding machines used by industrial and mining enterprises are: AC arc welding machine, DC welding machine, argon arc welding machine, CO2 shielded welding machine, butt welding machine, spot welding machine, submerged arc welding machine, high frequency welding machine, flash welding machine, pressure welding machine and collision welding machine.

The main difference between AC welding machine and DC welding machine is that AC welding machine is generally used in steel structure manufacturing units or general machinery or agricultural machinery manufacturing units. DC is mainly used to manufacture pressure vessel boilers, pipelines or welding machines of important structural manufacturing units.

2. There are two kinds of DC welding machines: one is to add rectifier components on the basis of AC motor, and the other is DC generator. DC welder mainly welds nonferrous metals and pig iron. AC welder mainly welds steel plates.

3. Argon arc welding machine, CO2 gas shielded welding machine, high frequency butt welding machine, flash butt welding machine. Argon arc welding machine and carbon dioxide gas shielded welding machine can mainly weld thin plates and colored gold layers below 2MM. Flash butt welding machine is mainly used for butt welding copper-aluminum joints and other objects, and high-frequency butt welding machine is mainly used for welding steel pipes in pipe factory.

4. Submerged arc welding mainly welds thick steel structures such as steel structures, bridge H-beams and I-beams.

5, gas shielded welding machine: argon arc welding, carbon dioxide shielded welding, under the protection of gas, the welding machine will not be oxidized, the solution welding is firm, and it can weld colored gold layers and thin materials.

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

7. Butt welding machine: The anchor chain factory mainly welds iron cables and other objects on the anchor. You can dock with Yuangang and so on.

Matters needing attention in the use of electric welding machine:

1, should according to the technical conditions of the work, choose a reasonable welding process, are not allowed to use overload, are not allowed to use high current welding, are not allowed to use electric welding machine for metal cutting operations.

2. During load welding, the temperature rise of Class A welder shall not exceed 60 degrees, and Class B welder shall not exceed 80 degrees; otherwise, it shall be stopped and cooled before welding.

3, welding machine workplace should be kept dry, well ventilated. When moving the welder, cut off the power supply, and do not drag the power supply to move the welder. In case of sudden power failure during welding, the power supply should be cut off.

4, in the welding, are not allowed to adjust the current. When stopping welding, use the adjusting handle to adjust, not too fast or too hard, so as not to damage the adjuster.

5, it is strictly prohibited to do welding work under the workpiece of crane operation.

6. When welding in the area with crane wire rope, care should be taken not to accidentally touch the lifting wire rope on the welding machine ground to avoid sparks and accidents.

7, must be in the wet area construction, welder must stand on the insulation board, are not allowed to touch the welding wire, are not allowed to use the arm with electrode holder. ?
