QW-407.1 A separate procedure qualification is
required for each of the following:
(a) For P-Numbers 1 through 6 and 9 through 15F
materials, the following postweld heat treatment conditions
apply:
(1) no PWHT
(2) PWHT below the lower transformation temperature
(3) PWHT above the upper transformation temperature
(e.g., normalizing)
(4) PWHT above the upper transformation temperature
followed by heat treatment below the lower transformation
temperature (e.g., normalizing or quenching
followed by tempering)
(5) PWHT between the upper and lower transformation
temperatures
(b) For all other materials, the following postweld heat
treatment conditions apply:
(1) no PWHT
(2) PWHT within a specified temperature range
QW-407.2 A change in the postweld heat treatment
(see QW-407.1) temperature and time range
The procedure qualification test shall be subjected to
PWHT essentially equivalent to that encountered in the
fabrication of production welds, including at least 80%
of the aggregate times at temperature(s). The PWHT
total time(s) at temperature(s) may be applied in one
heating cycle. This variable does not apply to a WPS qualified
for welding base metals that are assigned to P-No. 8,
P-Nos. 21 through 26, and P-Nos. 41 through 49.

QW-163 ACCEPTANCE CRITERIA — BEND TESTS
The weld and heat-affected zone of a transverse weldbend
specimen shall be completely within the bent portion
of the specimen after testing.
The guided-bend specimens shall have no open discontinuity
in the weld or heat-affected zone exceeding 1∕8 in.
(3 mm), measured in any direction on the convex surface
of the specimen after bending. Open discontinuities occurring
on the corners of the specimen during testing shall not
be considered unless there is definite evidence that they
result from lack of fusion, slag inclusions, or other internal
discontinuities. For corrosion-resistant weld overlay cladding,
no open discontinuity exceeding 1∕16 in. (1.5 mm),
measured in any direction, shall be permitted in the cladding,
and no open discontinuity exceeding 1∕8 in. (3 mm)
shall be permitted along the approximate weld interface.
