Tungsten Inert Gas, abbreviated TIG.The literal translation is tungsten inert gas welding, commonly known as non-melting gas welding.Inert gas arc welding using pure tungsten or activated tungsten (thorium tungsten, cerium tungsten, zirconium tungsten, lanthanum tungsten) as non-melting electrode has high quality but low speed.TIG refers to non-melting electrode gas shielded welding, which is an arc welding method using external gas as a protective medium. Its advantages are good visibility of arc and molten pool and convenient operation.No slag or little slag, no post-weld slag cleaning.However, special wind protection measures should be taken when working outdoors.

Welding Skills (1)
TIG welding itself belongs to the open arc operation can observe the shape and flow of the molten pool, is much better than the electrode arc welding.
Welding Skills (2)
Control of welding hand stability is the biggest key to avoid shivering and burning of the dock pole resulting in tungsten inclusion in the molten pool.The control method can only be used to hold the welding gun index finger to support the welded pipe or plate.The length of the tungsten pole can be selected according to the depth of the hole, generally 3-5mm.
The wire transport method can be selected according to the size of the breach, the breach Angle is small, the wire can be placed in the middle of the tank, continuous feeding.When the tear is large, both sides can be used to feed the wire (to be quite skilled, avoid touching the dock pole), and the welding gun moves around to make the edge fuse well.
