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?

There are several reasons for arcing:First, the power load capacity is poor.1, power line is too long, too small;2, the power supply voltage is too low, two, welding machine itself problems1, secondary current adjustment is too small, and the diameter of the welding rod does not match.2, each node serious corrosion, bad contact.Three. Welding rod quality problem.1, welding rod itself quality is slightly lower,2, welding rod damp, medicine skin deterioration or failure.

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?

LZ, this name is interesting. Double wire welding is two welding machines, both guns at the same time welding, can be the same arc pit, can also be a front, a rear, two arc pit, or both sides simultaneously. Yes, the welding wire is different and the welding parameters are different. Double Pulse GMAW, two pulse superposition, with wave superposition theory as a pulse for welding, one droplet per pulse, a pulse, is responsible for the scale pattern.

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

MIG:Metal Inert Gas welding, MIG welding, argon gas, helium (Ar) (He) or a mixed gas, do not react with liquid metal, only isolated from the air, so stable arc combustion, droplet transition smooth, stable, no fierce splash, the most suitable for welding of aluminum, copper, titanium and other non-ferrous metals, can also be used for steel, such as stainless steel, heat-resistant steel welding etc.;MAG:Metal Active Gas welding, metal active gas welding, gas by inert gas and a small amount of oxidizing gases (O2, CO2 or a mixed gas) mixture, without changing or basically does not change the inert gas arc characteristics under the condition of improving arc stability, improve the forming and reduce the radiation intensity of arc weld, welding used in black metal materials.
