ARC BRAZING
A brazing process wherein the heat is obtained from an electric arc
formed between the base metal and an electrode, or between two
electrodes.
ARC CUTTING
A group of cutting processes in which the cutting of metals is
accomplished by melting with the heat of an arc between the electrode
and the base metal. See CARBON-ARC CUTTING, METAL-ARC
CUTTING, ARC-OXYGEN CUTTING, AND AIR-ARC CUTTING.
ARC LENGTH
The distance between the tip of the electrode and the weld puddle.
ARC-OXYGEN CUTTING
An oxygen-cutting process used to sever metals by a chemical reaction
of oxygen with a base metal at elevated temperatures.
ARC VOLTAGE
The voltage across the welding arc.
ARC WELDING
A group of welding processes in which fusion is obtained by heating
with an electric arc or arcs, with or without the use of filler metal.
AS WELDED
The condition of weld metal, welded joints, and weldments after
welding and prior to any subsequent thermal, mechanical, or chemical
treatments.
ATOMIC HYDROGEN WELDING
An arc welding process in which fusion is obtained by heating with an
arc maintained between two metal electrodes in an atmosphere of
hydrogen. Pressure and/or filler metal may or may not be used.
AUSTENITE
The non-magnetic form of iron characterized by a face-centered cubic
lattice crystal structure. It is produced by heating steel above the upper
critical temperature and has a high solid solubility for carbon and
alloying elements.
AXIS OF A WELD
A line through the length of a weld, perpendicular to a cross section at
its center of gravity.
BACK FIRE
The momentary burning back of a flame into the tip, followed by a
snap or pop, then immediate reappearance or burning out of the flame.
BACK PASS
A pass made to deposit a back weld.
