Metal contribution: no contribution or separate contribution.
5.1 Process description
Refractory electrode welding is commonly known as TIG (Tungsten Inert Gas) welding. In English-speaking countries, it is also known as GTAW or Gas Tungsten Arc Welding. In France, it is often referred to as argon welding.
The principle of refractory electrode welding is shown in its manual form on figure 22.
The equipment includes an AC or DC power source, a priming device, a gas cylinder with pressure reducer and flow meter, a process-specific...
