Glossary “gas tungsten arc cutting (GTAC)” Definition:
Arc cutting process that uses a single tungsten electrode with gas shielding.

Glossary “gas tungsten arc welding (GTAW)” Definition:
Arc welding process that uses an arc between a non-consumable tungsten electrode and the weld pool.

Glossary “gas turbine engine” Definition:
Internal combustion engine in which the shaft is spun by combustion gases flowing against curved turbine blades located around the shaft.

Glossary “gas filled shock absorber” Definition:
A shock that uses nitrogen gas, at 25 times atmospheric pressure, to pressurize the fluid in the shock to reduce or prevent aeration or foaming. Also known as gas shock.

Glossary “gas metal arc welding (GMAW)” Definition:
Arc welding process that uses an arc between a continuous filler metal electrode and the weld pool.

Glossary “gas transfer velocity” Definition:
Speed at which the A/F mixture spreads out in the combustion chamber during the power phase.

Glossary “gas ports” Definition:
Series of holes drilled from the crown of a piston to the top ring groove, providing combustion pressure to force the ring against the cylinder wall, ensuring a more effective seal.

Glossary “gas regulator” Definition:
Device used to control the delivery of gas at a substantially constant pressure.

Glossary “gas shock” Definition:
Term used for gas filled shock absorber.

Glossary “gas guzzler” Definition:
Vehicle having excessive fuel consumption.

Glossary “gas hog” Definition:
Term often used for gas guzzler.

Glossary “gas flow rate” Definition:
A measurement of how fast gas flows over the weld puddle in MIG welding.

Glossary “gas axe” Definition:
Term used for cutting torch

Glossary “gas bypass line” Definition:
Term used for hot gas bypass line.

Glossary “gas bypass valve” Definition:
Term used for hot gas bypass valve.

Glossary “gas cylinder” Definition:
Container used for the transportation and storage of compressed gas.

Glossary “gas defrosting” Definition:
The use of hot, high-pressure gas in the evaporator to remove frost or ice buildup.

Glossary “gas fade” Definition:
Brake fade due to hot gases and dust that reduce friction between the drum or rotor during prolonged hard braking.
