Use of an external shielding gas, which produces an electric arc used to melt metal. The arc is produced between the consumable electrode and the metal that is to be cut. Electric current is supplied by a variable transformer, through heavy electrical leads. One lead is connected to the electrode and the other is connected to the metal being cut. The electrode is then held close to the metal so that an electric arc can move from the electrode to the metal, completing the circuit.
Gas metal arc welding
Welding which is done by using an external shielding gas to weld the metals together with the heat generated by the electric arc that is produced between a consumable electrode and the metal being welded. Deep penetration of the weld, along with rapid deposits of weld metal are provided by this process.
Gas pliers
Pipe gripping pliers with a curved, toothed cutout in the jaws with two different ranges of jaw openings.
Gas pocket
Void space that weakens a casting or weld metal.
Gas stabilizer
Gas tungsten arc cutting
Usage of an electric arc flowing from a non-melting tungsten electrode to the metal to be cut. The electrode holder that goes around the electrode has a gas passage that has an inert gas flowing through, which isolates the molten metal of the cut from any oxygen that would have detrimental effects on the hot metal. A hose connect to a tank supplies the gas.
Gas tungsten arc welding
Electric arc welding process, which uses an electrode, which cannot be destroyed, to maintain an arch which is surrounded by inert shielding gas. The weld wire is fed into the weld separately.
Gas turbine
A type of turbine in which combusted, pressurized gas is directed against a series of blades connected to a shaft, which forces the shaft to turn to produce mechanical energy.
Gas welding
Melting of the base material with a fuel and oxygen burning torch and feeding the weld metal into the weld.
Gasification
The process in which a solid fuel is converted into a gas; also known as pyrolitic distillation or pyrolysis. Production of a clean fuel gas makes a wide variety of power options available.
