The order in which the weld beads of a multipass weld are deposited
with respect to the cross section of a joint. See BLOCK SEQUENCE.
BUTT JOINT:
A joint between two workpieces in such a manner that the weld joining
the parts is between the surface planes of both of the pieces joined.
BUTT WELD:
A weld in a butt joint.
BUTTER WELD:
A weld caused of one or more string or weave beads laid down on an
unbroken surface to obtain desired properties or dimensions.
CAPILLARY ATTRACTION:
The phenomenon by which adhesion between the molten filler metal
and the base metals, together with surface tension of the molten filler
metal, causes distribution of the filler metal between the properly fitted
surfaces of the joint to be brazed.
CARBIDE PRECIPITATION:
A condition occurring in austenitic stainless steel which contains
carbon in a supersaturated solid solution. This condition is unstable.
Agitation of the steel during welding causes the excess carbon in
solution to precipitate. This effect is also called weld decay.
CARBON-ARC CUTTING:
A process of cutting metals with the heat of an arc between a carbon
electrode and the work.
CARBON-ARC WELDING:
A welding process in which fusion is produced by an arc between a
carbon electrode and the work. Pressure and/or filler metal and/or
shielding may or may not be used.
CARBONIZING FLAME:
An oxyacetylene flame in which there is an excess of acetylene. Also
called excess acetylene or reducing flame.
CASCADE SEQUENCE: Subsequent beads are stopped short of a previous
bead, giving a cascade effect.
CASE HARDENING:
A process of surface hardening involving a change in the composition
of the outer layer of an iron base alloy by inward diffusion from a gas
or liquid, followed by appropriate thermal treatment. Typical
hardening processes are carbonizing, cyaniding, carbonitriding, and
nitriding.
CHAIN INTERMITTENT FILLET WELDS:
Two lines of intermittent fillet welds in a T or lap joint in which the
welds in one line are approximately opposite those in the other line.
