TIG Welding

TIG(GTAW) Welding


Gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a nonconsumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by a shielding gas (usually an inert gas such as argon), and a filler metal is normally used, though some welds, known as autogenous welds, do not require it. A constant-current welding power supply produces energy which is conducted across the arc through a column of highly ionized gas and metal vapors known as a plasma.

GTAW is most commonly used to weld thin sections of stainless steel and non-ferrous metals such as aluminum, magnesium, and copper alloys. The process grants the operator greater control over the weld than competing processes such as shielded metal arc welding and gas metal arc welding, allowing for stronger, higher quality welds. However, GTAW is comparatively more complex and difficult to master, and furthermore, it is significantly slower than most other welding techniques. A related process, plasma arc welding, uses a slightly different welding torch to create a more focused welding arc and as a result is often automated.

TIG or Stick [SMAW or MMA] welding
TIG welding
Direct Current Stick [SMAW or MMA] welding
Arc striking by contact.It can pollute the welding pool and causes less electro-irradiated disturbances.
Arc striking without contact.The electrode tip does not wear out.
It offers an easy start in all welding positions.
Increases the welding current at the beginning of the welding
Allows you to easily withdraw your electrode without damaging it in case of sticking metal
Increases the welding current in order to avoid the sticking when the electrode enters in melted metal

High efficiency
Light and versatile
Good performance in MMA, TIG and Pules
For professional working, stainless steels esp.
