Tig Welder Welding Equipment

The process of TIG welding is a process of fusion welding, autogenous. The electrical arc between the electrode body infusible, which is under protective gas, and the material to be welded. The electrode of the TIG is Tungsten, material with high melting temperature and good properties of thermionic emission.

The TIG welding process

• Manual: length of arc and electrode-controlled soldering iron;
• Semi-automatic: arc length and electrode controlled by the machine, while the welder moves the electrode along the weld;
• Automatic: all operations are performed by the robot.

It has a stable arc that allows good control of the smelting bath. However, the TIG is a very productive process, used for small thicknesses. It can weld all types of metals and non metals used as filler material or even a stick, thanks to the arc energy very focused, just alongside the two ends to be welded without using filler material.

The electrodes used for TIG welding process are of four types:

1. Pure tungsten electrode
2. Tungsten electrodes with added oxide Thor
3. Tungsten electrodes with added zirconium
4. Tungsten electrodes with strips of tungsten thoro
