FAQ

What brand of MAG/MIG welding machine good stability high load rate (the main processing non-ferrous metals such as copper and aluminum) and the teacher requested to introduce.

Germany's Fries 3000 type AC and DC welding machine, and then the aviation industry is very popular, but the price is high. And the Miller welding machine made in America, especially good for butt welding. You can refer to the reference.

MIG automatic welding is always broken arc is how ah?

The description of the problem is too vague. What is the phenomenon of arc breaking?Two possibilities:1. current voltage is relatively large, but not to melt the wire too fast, there will be a section of a wire melted, intermittent arc2., feeding wire interruption, arc back to the wire feeder, because the discharge distance is too large, resulting in arcing

Which is better, TIG welding method and MIG welding method?

It depends on your welding requirements

What are the principles of Tandem twin wire welding and monofilament composite pulsed MIG welding?

Tandem double wire welding is to place two welding wires at a certain angle in a specially designed welding torch, and two welding wires are respectively supplied by independent power supply. In addition to feeding speed can be different, other parameters, such as: wire material, diameter, pulse, etc. can be set independently of each other, so as to ensure the arc work in the best state. Compared with other twin wire welding technology, the welding efficiency and welding speed are improved because the arc of two welding wires is burned in the same molten pool and the total welding current is increased. At the same time, because the two welding wires are sent to the same molten pool alternately, the mixing action of the welding pool is reduced, and the sensitivity of the porosity is improved, and the quality of the weld is improved.

The difference between TIG welding and MIG welding

TIG non melting pole inert gas arc weldingThis is a non - melting inert gas welding, which utilizes the arc between the tungsten electrode and the workpiece to fuse the metal. Tungsten welding process to melt, only play the role of the electrode. At the same time, argon is sent by the nozzle of the torch to protect it. Additional metals can be added as needed. Internationally known as TIG welding.Because of the good control of heat input, the non melting pole inert gas arc welding is an excellent method to connect sheet metal and backing welding. This method can be used almost exclusively for all metals, especially for welding aluminum and magnesium, metals that form refractory oxides, and active metals such as titanium and zirconium. The weld quality of this welding method is high, but the welding speed is slower compared with other electric arc welding.MIG metal inert gas arc weldingThe welding method uses continuous arc welding as an heat source between the welding wire and the workpiece, and protects the arc by the inert gas ejected from the nozzle of the torch.The common protective gases used in MIG arc welding are argon, helium, or the mixture of these gases. When argon or helium is used as a protective gas, it is called "MIG inert gas arc welding" (referred to as "MIG welding" in the world).The major advantage of MIG welding is that it can be conveniently welded in various positions, and also has the advantages of fast welding speed and high deposition rate. MIG welding is suitable for stainless steel, aluminum, magnesium, copper, titanium, zirconium and nickel alloys. The arc welding can be carried out by using the welding method.

The difference between MAG welding machine and MIG welding machine

Active gas shielded arc welding (MIG) can be applied to most of the major metals, including carbon steel and alloy steel.Inert gas shielded welding (MAG) is suitable for stainless steel, aluminum, magnesium, copper, titanium, zirconium and nickel alloys. The arc welding can be carried out by using the welding method.
