ASME SEC IX EXAM QUESTIONS AND
ANSWERS 2024-2025
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
QW-100.2 specifies the basic criterion for welder qualification as determining the

qualifications to demonstrate welding operators' ability to make sound welds? -
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 more
than one inch (25mm) thick, multiple tension test specimens should be collected at
each place under the rules of QW-151.1 for plate, QW-151.2 for pipe, and

broke in the base metal outside of the weld and weld interface. What is the
minimum permissible tensile strength for the WPS qualifications?
What should the inspector do with a 5/32-length guided bend specimen that has an
open discontinuity in the heat-affected zone on the convex surface after bending? -
ANSWER The test fails if the open discontinuity in the weld or heat affected zone
is greater than 1/8". QW-163
What should the inspector do if a guided bend specimen has an open discontinuity
on the corner of the convex surface of the specimen after bending that measures
5/32" in length? - ANSWER Look for signs of absence of fusion, slag inclusions,
or other internal discontinuities. QW-163
Which testing standard must the Charpy V-Notch impact test adhere to achieve
WPS qualifications? - ANSWER ASME SA-370 QW-171.1
- ANSWER At a given low magnification? QW/QB-492
, When is incomplete fusion defined as a radiographic linear indication? -
ANSWER: When the length is greater than three times the width.
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-No. of SFA-5.1 classification E6020? - ANSWER F-1
What is the F-No. of SFA-5.5 classification E8018-B3L, Low alloy steel electrodes
for shield metal arc welding? - ANSWER F-No. 4.
What is the A-No. when welding SA-240 grade 304L using SFA 5.4 classification
E309L (austenitic stainless steel 18CR-8Ni) filler metal? - ANSWER (A-No. 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 get A#
What is the A-No. when welding an ASME SA-105 flange grade B pip using an
AWS A 5.1 E7018 electrode? - ANSWER (A-No.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 get A#.
What is the A-No. when welding ASME SA-312 type TP 316 pipe with an AWS A
5.4 E316 electrode? - ANSWER (A-No. 8) SA-312 as a nominal composition of 16
Cr-21Ni-2Mo. on QW/QB 422 cross reference QW-442 A- numbers with
analysis% to get A#.
