The Difference Between TIG VS MIG
ALAND WELDING Let you feel the most sincere welding service
1、TIG VS MIG Different Methods
(1) TIG welding: A welding method that uses pure Ar as the shielding gas and tungsten as the electrode.
(2)MIG welding: MIG welding is melting extremely inert gas shielded electric welding. It uses inert gases such as Ar as the main shielding gas, including pure Ar or Ar gas mixed with a small amount of active gas (such as less than 2% O2 or less than 5% CO2 Gas) welding method for metal arc welding.
2、TIG VS MIG Different Characteristics
(1) TIG welding: It can weld a wide range of materials, including workpieces with a thickness of 0.6mm and above. The materials include alloy steel, aluminum, magnesium, copper and its alloys, gray cast iron, ordinary dry, various bronzes, and nickel , silver, titanium and lead. The main areas of application are welding of thin and medium thickness workpieces and as root pass on thicker sections.
(2) MIG welding: MIG welding can be used in DC reverse connection. It has good cathode atomization when welding aluminum, magnesium and other metals, which can effectively remove the oxide film and improve the welding quality of the joint; when MIG welding welds aluminum and aluminum alloys , sub-jet droplet transfer method can be used to improve the quality of welded joints.
1、TIG VS MIG Have Different Principles
(1) TIG welding: Inert gas is fed through the welding torch to form a shield around the arc and the welding pool. To increase heat input, 5% hydrogen is generally added to the argon.But , when welding ferritic stainless steel, hydrogen cannot be added in argon. Gas consumption is about 3 to 8 liters per minute. During the welding process, in addition to blowing inert gas from the welding torch, it is also best to blow in gas to protect the back of the weld from under the weld.
(2) MIG welding: MIG (MAG) welding uses a meltable welding wire as the electrode. And the arc burning between the continuously fed welding wire. And the workpiece to be welded is used as a heat source to melt the welding wire and the base metal. During the welding process, the protective gas-argon is continuously delivered. To the welding area through the welding gun nozzle to protect the arc. Molten pool and nearby base metal from the harmful effects of the surrounding air. The continuous melting of the welding wire should be transferred into the weld pool in the form of droplets. fused with the molten base metal, and condensed to form the weld metal.
