| GTAW WELDING
|
Tiaano adopts GTAW welding for all exotic metals (Titanium, Tantalum, Niobium, Zirconium, Nickel, Hastelloy, Monel, Inconel, Super Duplex).
Gas Tungsten Arc Welding (GTAW) is frequently referred to as TIG welding. TIG welding is a commonly used high quality welding process. TIG welding has become a popular choice of welding processes when high quality, precision welding is required. In TIG welding an arc is formed between a non-consumable tungsten electrode and the metal being welded. Gas is fed through the torch to shield the electrode and molten weld pool. If filler wire is used, it is added to the weld pool separately.

| Advantages of GTAW
|
- Superior quality welds.
- Welds can be made with or without filler metal.
- Precise control of welding variables (heat).
- Free of spatter
- Low distortion

| GTAW Shielding Gases
|
- Argon
- Argon + Hydrogen
- Argon / Helium
|
Helium is generally added to increase heat input (increase welding speed or weld penetration). Hydrogen will result in cleaner looking welds and also increase heat input; however, Hydrogen may promote porosity or hydrogen cracking.
