ASME SECTION 9 EXAM QUESTIONS
WITH CORRECT ANSWERS
What is a welding procedure specification? - ANSWER a written document that
directs the welder in completing production welds in compliance with the code
criteria. (QW-100.1)
What is the aim of WPS qualification? - ANSWER to ensure that the weldment
proposed for fabrication has the necessary qualities for its intended application.
QW-100.1
What is the basic performance criterion for welder qualification? - ANSWER

ANSWER Radiographic and ultrasonic examinations can be substituted. (QW-143)
,What minimal thickness may necessitate numerous reduced section plate tension
test specimens for WPS Qualifications? - ANSWER When test coupons are over
one inch 25mm thick, multiple tension test specimens should be taken at each site
under the rules of QW-151.1 for plate QW-151.2 for pipe, and QW-151.3 for
turned specimens. QW-151.1(b)
A tensile test is performed on the SA-333 grade 6 plate that has been normalized
and tempered to an acceptable stress of 17,100 psi as part of the qualification of

the tensile test specimen? - What is the answer, 0.998 inches? (QW-152,
QW-462.1)
A tensile test on SA-335 grade P1 pipe was done as part of the qualifying process
for welding procedures. The test specimen measured 0.75" wide and 0.75" thick.
The specimen broke in the base metal outside of the weld and weld contact. What
is the minimum permissible tensile strength for WPS qualification? - SA-335 grade
P1 55ksi. 0.95 x 55 ksi equals 52.25 Ksi (QW-152).
A 5/32-long guided bend specimen with an open discontinuity in the heat affected
zone on the convex surface after bending. What should the inspector do? -
ANSWER The test fails if there is an open discontinuity in the weld or
heat-effected zone that is more than 1/8". QW-163
A guided bend specimen with an open discontinuity on the corner of the specimen's
convex surface after bending, measuring 5/32" long. What should the inspector do?
- ANSWER Inspect further for signs of fusion failure, slag inclusions, or other
internal discontinuities. QW-163
Which testing standard must the Charpy V-Notch impact test meet for WPS
qualifications? ANSWER ASME SA-370 QW-171.1
, What magnification is used for a filet weld test macro inspection during procedures
or performance qualifications? - ANSWER At a specific low magnification?
QW/QB-492
When is partial fusion classified as a radiographic linear indication? - ANSWER
When the length exceeds three times the breadth. QW.191.1.2.1(a)
The minimum specified tensile strength of ASME SA-516 grade 70 is 70 ksi.
What is the nominal composition of ASME SA-333 Grade 6? - Answer: C-Mn-Si
steel.
What is the F-number for SFA-5.1 classification E6020? - ANSWER F-No. 1.
What is the F-number for SFA-5.5 classification E8018-B3L, low alloy steel
electrodes for shield metal arc welding? - ANSWER F-4
What is the A-No. for welding SA-240 grade 304L with SFA 5.4 classification
E309L (austenitic stainless steel 18CR-8Ni) filler metal? - ANSWER (A-8). -
SA-240 grade 304L has a nominal composition of (18Cr-8Ni) on QW/QB 422
cross reference QW-442 A- numbers with analysis% to obtain A#.
What would be the A-number when welding an ASME SA-105 flange grade B pip
with an AWS A 5.1 E7018 electrode? - ANSWER (A-1) SA-105 flange has a
nominal composition of C, and 106 has a composition of C-Si.) on QW/QB 422
cross reference QW-442 A- numbers with analysis% to obtain A#
