The difference between TIG welding and MIG welding
TIG is a non melting electrode TIG welding, is a manual electric arc welding with argon gas protection, while MIG belongs to inert gas welding consumable electrode, and the TIG is different to manual wire for automatic wire feeding.
Using mixed gas 75--95%, Ar + 25--5,% CO2, (standard ratio: 80%Ar + 20%CO2) as the protection gas, MIG welding - called MAG welding. The process of using a 98% Ar + 2%O2 or 95%Ar + 5%CO2 as a protective gas for MIG welding of a solid stainless steel wire is called MIG welding. Therefore, MIG is welded stainless steel plate, MAG is welded ordinary steel plate.
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.
