COMMUTORY CONTROLLED WELDING
The making of a number of spot or projection welds in which several
electrodes, in simultaneous contact with the work, progressively
function under the control of an electrical commutating device.
COMPOSITE ELECTRODE
A filler metal electrode used in arc welding, consisting of more than
one metal component combined mechanically. It may or may not
include materials that improve the properties of the weld, or stabilize
the arc.
COMPOSITE JOINT
A joint in which both a thermal and mechanical process are used to
unite the base metal parts.
CONCAVITY
The maximum perpendicular distance from the face of a concave weld
to a line joining the toes.
CONCURRENT HEATING
Supplemental heat applied to a structure during the course of welding.
CONE
The conical part of a gas flame next to the orifice of the tip.
CONSUMABLE INSERT
Preplaced filler metal which is completely fused into the root of the
joint and becomes part of the weld.
CONVEXITY
The maximum perpendicular distance from the face of a convex fillet
weld to a line joining the toes.
CORNER JOINT
A joint between two members located approximately at right angles to
each other in the form of an L.
COVER GLASS
A clear glass used in goggles, hand shields, and helmets to protect the
filter glass from spattering material.
COVERED ELECTRODE
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.
