Gas tungsten arc welding. Gas tungsten arc welding (GTAW, also known as tungsten inert gas welding or TIG, and heliarc welding when helium is used) is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. The weld area and electrode are protected from oxidation or other atmospheric contamination by an inert ...
Spray transfer GMAW. Gas metal arc welding (GMAW), sometimes referred to by its subtypes metal inert gas (MIG) and metal active gas (MAG) is a welding process in which an electric arc forms between a consumable MIG wire electrode and the workpiece metal (s), which heats the workpiece metal (s), causing them to fuse (melt and join).

Two wheel-shaped electrodes roll along workpieces, applying pressure and current. Aerospace industry, steel drums, tubing. Projection welding. 23.
Shielding gases are inert or semi- inert gases that are commonly used in several welding processes, most notably gas metal arc welding and gas tungsten arc welding (GMAW and GTAW, more popularly known as MIG (Metal Inert Gas) and TIG (Tungsten Inert Gas), respectively). Their purpose is to protect the weld area from oxygen, and water vapour.
Altyn was developed on the basis of the PSH-77 helmet created by TIG company from Switzerland. [1] The Soviet Union purchased PSH-77 helmets for use by Alpha Group Spetsnaz, who used them during operation Storm-333 in the Soviet–Afghan War. These helmets became very popular with the KGB servicemen, and as such, a decision was made to produce ...
