nonferrous filler metal having a melting point above 800 °F (427 °C),
but below that of the base metal. The filler metal is distributed in the
joint by capillary attraction.
BLOCK SEQUENCE
A building up sequence of continuous multipass welds in which
separated lengths of the weld are completely or partially built up
before intervening lengths are deposited. See BUILDUP SEQUENCE.
BLOW HOLE
see GAS POCKET.
BOND
The junction of the welding metal and the base metal.
BOXING
The operation of continuing a fillet weld around a corner of a member
as an extension of the principal weld.
BRAZING
A group of welding processes in which a groove, fillet, lap, or flange
joint is bonded by using a nonferrous filler metal having a melting
point above 800 °F (427 °C), but below that of the base metals. Filler
metal is distributed in the joint by capillary attraction.
BRAZE WELDING
A method of welding by using a filler metal that liquefies above 450°C
(842 °F) and below the solid state of the base metals. Unlike brazing,
in braze welding, the filler metal is not distributed in the joint by
capillary action.
BRIDGING
A welding defect caused by poor penetration. A void at the root of the
weld is spanned by weld metal.
BUCKLING
Distortion caused by the heat of a welding process.
BUILDUP SEQUENCE
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.
