Information about TIG Welders online

gas arc welding of tungsten (TIG), also known as tungsten inert gas (TIG), is an arc welding process that uses a non-consumable tungsten electrode to produce welding. Gas tungsten arc welding is most commonly used to weld thin sections of stainless steel and light metals, such as aluminum, magnesium, and copper alloys, among other metallic properties, except for lead and zinc. The process gives the operator greater control over the weld than procedures like shielded metal arc welding and gas metal arc welding competitors, enabling stronger, high quality welds.

The arc was discovered and developed by Humphry Davy in 1800. CL Coffin also had the idea of welding in inert gas atmosphere 1890, But even at the beginning of 1900, non-ferrous welding materials, as aluminum and magnesium remained difficult. To solve the problem, bottled inert gases were used in early 1930. The electric arc process was perfected in 1941, and became known as heliarc or tungsten inert gas welding because it utilized a tungsten electrode and helium as a shielding gas. In 1953, a new process based on GTAW was developed, called plasma arc welding. It provides greater control and improves weld quality using a nozzle to focus the arc, but is largely limited to automated systems, While it remains primarily a manual GTAW, the method of hand

Advantages.:

1- concentrated Arc

2- Don't Slag

3- No Spark & No Spatter

4- little or no smoke or fumes

5- More metals and welding alloys than any other process

6- good for welding thin materials

Disadvantages:

1- displacement speeds slower than other processes

2- filler metal deposition rates lower

3- hand-eye coordination is a skill required

4- bright UV rays than other processes

5- Equipment costs may be higher than other processes

6- Shielding gas concentrations can build up and displace the oxygen during welding in confined areas
