stainless steel or certain nickel-
base alloys, that occurs as the
result of sensitization in the heat-
affected zone during the welding
operation. [This is not a preferred
term.]
WET FILM GAUGE
Device for measuring wet film
thickness of a coating.
WORKING ELECTRODE
The test or specimen electrode in
an electrochemical cell.
WROUGHT
Metal in the solid condition that is
formed to a desired shape by
working (rolling, extruding,
forging, etc.), usually at an
elevated temperature.

YIELD POINT
The stress on a material at which
the first significant permanent or
plastic deformation occurs
without an increase in stress. In
some materials, particularly
annealed low-carbon steels,
there is a well-defined yield point
from the straight line defining the
modulus of elasticity.
YIELD STRENGTH
The stress at which a material
exhibits a specified deviation
from the proportionality of stress
to strain. The deviation is
expressed in terms of strain by
either the offset method (usually
at a strain of 0.2%) or the total-
extension-under-load method
(usually at a strain of 0.5%.)
