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.
DIE WELDING
A forge welding process in which fusion is produced by heating in a
furnace and by applying pressure by means of dies.
DIP BRAZING
A brazing process in which bonding is produced by heating in a molten
chemical or metal bath and by using a nonferrous filler metal having a
melting point above 800 °F (427 °C), but below that of the base metals.
The filler metal is distributed in the joint by capillary attraction. When
a metal bath is used, the bath provides the filler metal.
