GAS METAL-ARC WELDING: Describes a form of metal welding using a continuously fed consumable electrode and a shielding gas.
GAS TUNGSTEN-ARC WELDING: Describes the method of welding using a tungsten electrode and a shielding gas.
GAS WELDING: Describes the welding process widely used in body repair workshops.
GOUGING: Describes the cutting of a groove in the surface of metal using a gas cutting torch.
GRIP CHANNEL: Describes a steel channel spot-welded to a vehicle body to keep rubber seals in place.
GROOVE WELD: Describes a welding rod fused into a joint that has had its base metal removed to form a V, U, or J at the edge of the metals to be joined.
HAMMER WELDING: Describes metalworking technique that includes gas welding, preferably without the use of filler rod, followed by hammer and dolly work on the welded joint to smooth out any remaining imperfections.
HEATED TOOL WELDING: Describes a welding process in which the parts to be welded are pressed against a heated plate then pressed together to produce a fusion weld.
HEAT SHRINKING: Describes the procedure of shrinking dents in panels using a gas welder to heat local areas of the dents.
HELMET: Describes a protective hood designed to fit over an arc welder's head, equipped with a visor made of thick solid glass, allowing the welder to observe the electric arc in safety.
HORIZONTAL POSITION: Describes a weld performed on a horizontal seam that shows at least partially on its vertical surface.
HOT GAS WELDING: Describes a welding process involving the joining of thermoplastic materials by softening them with a jet of hot air, then joining them at the softened points.
INERT ARC WELDING: Describes all of the arc welding processes in the fusion welding category, with TIG welding, a typical inert arc welding process mainly used for repair work being among the better known.
INERT GAS-ARC WELDING: Describes the procedure of surrounding the arc with a gas that does not react with the electrode and base metal, keeping the atmosphere away from the arc.
LAYER: Describes a certain weld metal thickness comprising more than one pass.
LEAD WIRE: Describes a welding term that refers to the wire that transmits electric power source to the electrode holder or ground clamps.
LENS: Describes specially treated glass through which a welder may stare through an intense flame without their eyesight being affected by the glare of the flame.
MIG WELDING: Describes a method of arc welding where the electric current is provided by filler metal wire, cooled and shielded from air access of air by a stream of chemically inert gas, thus preventing the weld from oxidising.
MIXING CHAMBER: Describes a part of the welding torch where the welding gases are closely mixed before combustion.
OUTSIDE CORNER WELD: Describes a type of weld in which two pieces of metal are fused on the underpart of the seam.
OVERHEAD POSITION: Describes a type of weld made on the underside of the joint with the face of the weld in a horizontal plane.
OVERLAP: Describes an extension of the weld face that goes beyond the tip of the weld.
OXIDISING FLAME: Describes a type of flame produced by an excess of oxygen in the torch mixture, leaving some free, which tends to burn the molten metal.
OXYGEN ACETYLENE CUTTING: Describes the act of cutting metal using an oxygen jet incorporated with an oxygen-acetylene burner, preheating flame or flames.
OXYGEN-ACETYLENE WELDING: Describes a method of welding, using as a fuel a combination of the two gases - oxygen and acetylene.
OXYGEN REGULATOR: Describes an automatic valve, used in welding and cutting, to reduce cylinder pressures to align torch pressures while keeping the pressures constant.
