The welding machine is the purpose of melting the welded and welding materials on the high -temperature arc generated by the positive and negative bipolar in the instantaneous short circuit to combine the contact material to combine the contacts.Its structure is very simple, which is a high -power transformer.The welding machine can generally be divided into two types according to the type of output power supply, one is AC power supply and the other is DC power.They use the principle of inductance. The amount of inductance will produce huge voltage changes when connecting and disconnecting. The high -voltage arc generated by positive and negative bipolar in the instantaneous short circuit will melt the solder on the welded box to make them achieve the purpose of the atomic binding.Essence
What are the classifications of the welding machine
1. The main welded machines used by industrial and mining enterprises are: AC arc welding machine, DC welding machine, arc welding machine, carbon dioxide protection welding machine, welding machine, point welding machine, buried arc welding machine, high -frequency welding machine, flashing, flashingWelding machine, pressure welding machine, and bumper laser welding machine.
The difference between AC welding machine and DC welding machine is mainly because AC welding machines are generally used in steel structure manufacturing units or general general machinery or agricultural machinery manufacturing units.DC is mainly used in welding machines for manufacturing pressure vessel boilers, pipelines, or important structural manufacturing units.
⑴ The main application areas of inverter welding machines are the same, but the welding machine is more energy -saving and light.
⑵ The main application field of buried arc welding machines is large steel structure manufacturing units, pressure vessel boiler manufacturing units.
的 The main application areas of gas protection welding machines are large -scale steel structure manufacturing units or universal mechanical agricultural machinery, automobile manufacturers, anti -theft door processing plants, and units that manufacture pressure vessel boilers are now widely used in gas protection welding machines.
用 主要 arc welding machines are mainly used in pipelines, pressure vessel boilers, and stainless steel processing enterprises.
机 AC 氩 ??arc welding machines are mainly welded by aluminum welding units, and aluminum container manufacturing units.Welding of aluminum radiators.
2. There are two types of DC welding machines: one is to install rectifier elements under the basis of AC motors, and the other is DC generator.DC welding machines are mainly welded with color metal and raw iron.The main welded steel plates are the main welded steel plates.
3. Arc welding machine, carbon dioxide protection welding machine, high -frequency welding machine, flashing welding machine.The arc welding machine and the carbon dioxide gas protection machine can be welded with a thin plate and a non -colored gold layer of less than 2mm.Flash -to -welded machines are mainly connected with copper aluminum joints and other objects, and high -frequency welded steel pipes in high -frequency welding machines.
4. Buried arc welding main welded steel structure parts, bridge H steel, and workmark room beams and other thick steel structure materials.
5. Gas protection welding machine: arc welding and carbon dioxide protection welding. When welding machines are protected, it will not be oxidized, welded firmly, can be welded with color gold layers, and thin -welded materials.
6. Laser welding machine: The internal lead can be welded.
7. The welding machine: the iron cables and other objects on the welding anchor of the cable chain factory.Can be connected to Yuangang and so on.
What should I pay attention to when buying the welding machine
First, when buying a welding machine product, you must go to a regular manufacturer or large shopping mall to buy, and to buy brand -famous products with high market share.Do not want to go to small shops to buy it cheaply, the quality of the welding machine there cannot be guaranteed.
2. When buying, check whether the nameplate on the product has the name, production address, specification model, welding current regulation range, load continuous and input voltage current, etc.Welding machine.
3. When purchasing, the dealer can provide a product quality inspection report or a certificate.Because the welding machine is a national compulsory certification product, it must be confirmed whether the product has passed the "3C" certification when purchasing.You can also check online.
4. When buying, you must check whether the product has ground screws. There should be no paint on the ground screw connection.Whether the movement is cleaned or whether the insulation is damaged to ensure the safety of use, it can be detected if necessary.
5. Before buying, you can check the operation, conversion and installation of the switch on the panel before purchasing, the light extinguish of the power indicator, whether the fan part has abnormal vibration, the sound of the bee, whether there is a odor, the appearance of the appearance, whetherThere is a fever such as discoloration to ensure the quality of the welding machine and give full play to the performance of the welding machine.
6. If you want to purchase a gas protection welding machine, you must check whether the accessories are complete, whether the wire delivery machine has oil pollution, whether the rotation of the wire is stable, and whether the connecting cable is damaged to ensure the stability of the arc.
