Tungsten inert gas welding is a constant current drooping arc process. It is also known as TIG, gas tungsten arc welding - GTAW, wolfram inert gas - WIG, and under the trade names of argon arc and heli arc.

this is often referred to as the 'self-adjusting arc'. Metal Inert Gas (MIG) welding is a 'flat' arc process (constant) voltage. Also known as Metal Active Gas (MAG); CO2; Metal-arc Gas Shielded, flux core and GMAW (US).

Delaware Welding Schools: TIG/Tungsten Inert Gas Welding This lesson about the principles of Tungsten Inert Gas (TIG) welding. You will be able to describe and explain TIG torches, electrodes, shielding gases, and welding filler materials.

If we are to move towards sustainable development, we can no longer rely on reclamation/landfills to accept most of the inert construction waste. Although there are many initiatives to reduce and reuse construction waste, a substantial amount of materials still require disposal, either at public fill reception facilities or at landfills. To help you improve the management of waste on construction sites, ProjectLink has listed out some innovative solutions. These techniques and methodologies would help you ensure that the optimum levels of waste reduction, reuse and recycling are achieved. Integrate them in your construction waste management plan and encourage increased diversion of waste from landfill.

In DC welding the electrode usually has negative polarity, which reduces the risk of overheating which may otherwise occur with electrode positive. The ionized gas or plasma stream can attain a temperature of several thousand degrees centigrade.
