obtained from an inert gas such as helium or argon. Pressure and/or
filler metal may or may not be used.
GAS METAL-ARC (MIG) WELDING (GMAW):
An arc welding process in which fusion is produced by heating with an
electric arc between a metal electrode and the work. Shielding is
obtained from an inert gas such as helium or argon. Pressure and/or
filler metal may or my not be used.
GAS POCKET:
A weld cavity caused by the trapping of gases released by the metal
when cooling.
GAS TUNGSTEN-ARC (TIG) WELDING (GTAW):
An arc welding process in which fusion is produced by heating with an
electric arc between a tungsten electrode and the work while an inert
gas forms around the weld area to prevent oxidation. No flux is used.
GAS WELDING:
A process in which the welding heat is obtained from a gas flame.
GLOBULAR TRANSFER (ARC WELDING):
A type of metal transfer in which molten filler metal is transferred
across the arc in large droplets.
GOGGLES:
A device with colored lenses which protect the eyes from harmful
radiation during welding and cutting operations.
GROOVE:
The opening provided between two members to be joined by a groove
weld.
GROOVE ANGLE:
The total included angle of the groove between parts to be joined by a
groove weld.
GROOVE FACE:
That surface of a member included in the groove.
GROOVE RADIUS:
The radius of a J or U groove.
GROOVE WELD:
A weld made by depositing filler metal in a groove between two
members to be joined.
GROUND CONNECTION:
The connection of the work lead to the work.
GROUND LEAD:
See WORK LEAD.
