A metal electrode with a covering material which stabilizes the arc and
improves the properties of the welding metal. The material may be an
external wrapping of paper, asbestos, and other materials or a flux
covering.
CRACK:
A fracture type discontinuity characterized by a sharp tip and high ratio
of length and width to opening displacement.
CRATER:
A depression at the termination of an arc weld.
CRITICAL TEMPERATURE:
The transition temperature of a substance from one crystalline form to
another.
CURRENT DENSITY:
Amperes per square inch of the electrode cross sectional area.
CUTTING TIP:
A gas torch tip especially adapted for cutting.
CUTTING TORCH:
A device used in gas cutting for controlling the gases used for
preheating and the oxygen used for cutting the metal.
CYLINDER:
A portable cylindrical container used for the storage of a compressed
gas.
DEFECT:
A discontinuity or discontinuities which, by nature or accumulated
effect (for example, total crack length), render a part or product unable
to meet the minimum applicable acceptance standards or
specifications. This term designates rejectability.
DEPOSITED METAL:
Filler metal that has been added during a welding operation.
DEPOSITION EFFICIENCY:
The ratio of the weight of deposited metal to the net weight of
electrodes consumed, exclusive of stubs.
DEPTH OF FUSION:
The distance from the original surface of the base metal to that point at
which fusion ceases in a welding operation.
DIE:
a. Resistance Welding
. A member, usually shaped to the work contour,
used to clamp the parts being welded and conduct the welding current.
b. Forge Welding
. A device used in forge welding primarily to form
the work while hot and apply the necessary pressure.
