TIG welding classification

TIG welding according to the different electrodes are divided into two kinds of TIG and non-TIG welding.
Non-melting pole
Working principle and characteristics: Non-melting argon arc welding is the arc between the non-melting pole (usually tungsten) and the workpiece combustion between the arc in the welding arc does not react with a noble metal inert gas (commonly used argon ) To form a protective gas enclosure that prevents the oxidation of the gas and the absorption of harmful gases by keeping the tungsten tips, arcs and puddle and the hot metal adjacent to the heat affected zone out of contact with the air. Thus forming a dense welded joints, its mechanical properties are very good.


Melt the pole
Working principle and characteristics: The wire is fed through the wire wheel, the conductive tip is conductive, an arc is generated between the base metal and the welding wire, the welding wire and the base metal are melted, and the arc and the molten metal are protected by argon gas of inert gas for welding. It and the difference between TIG welding: one is the wire as the electrode, and is constantly melting into the pool, forming a weld after condensation; the other is the use of protective gas, with the melting of argon arc welding technology, protection Gas has been developed from a single argon gas mixture of a wide range of applications, such as Argon or helium gas as the protective gas called inert gas arc welding (in the world referred to as MIG welding); with inert gas When mixed with oxidizing gas (O2, CO2) as protective gas or CO2 gas or CO2 + O2 gas as protective gas, it is collectively referred to as MIG welding (referred to as MAG welding in the world). From its mode of operation, the most widely used is the semi-automatic welding and argon-rich mixed gas shielded welding, followed by automatic melting argon arc welding.
