CWB Exam – Practice Questions
Introduction:
The following practice questions are designed to help you prepare for the Canadian Welding Bureau
(CWB) Certification Exam. These questions cover essential topics such as welding processes, safety
protocols, welding symbols, blueprint interpretation, and inspection standards.
Use these questions to test your understanding, reinforce technical knowledge, and build confidence as
you prepare for certification.
QUESTIONS:
, 1.To measure the strength of a welded joint what mechanical test would you prescribe?
a) A transverse weld tension test
b) A charpy test.
c) A CTOD test.
d) An all weld metal tension test. e) A side bend test. - Accurate answers a) A transverse weld
tension test
2. Select the cutting process that would provide the narrowest heat affected zone when cutting 12.5 mm
(0.5 in) thick carbon steel.
a) Oxy-acetylene cutting.
b) Air-carbon arc cutting.
c) Oxy-propane cutting.
d) Plasma arc cutting.

welded in the horizontal position without rotating the assembly?
a) 1G
b) 2G
c) 3G
d) 5G
e) 6G - Accurate answers b) 2G

location?
a) Porosity.
b) Crack.
c) Inadequate penetration.
d) Lamination.
e) Burn-through. - Accurate answers b) Crack.

inches in thickness.
a) 0.012 in.
b) 0.015 in.
c) 0.025 in
d) 0.030 in. - Accurate answers c) 0.025 in
6. Which of the following statements concerning porosity is true?
a) Porosity cannot be trapped within a weld.
b) Porosity moves up through later passes and will show only in a final pass.
c) Porosity is restricted to the centre line of a weld.
d) Porosity can result from faulty welder technique.
e) Porosity can be dissipated by an appropriate heat treatment. - Accurate answers d) Porosity can
result from faulty welder technique.
7. An irregular, dense white spot is seen on the radiograph of a weld. Assuming it was caused by the
welding process used, which one of the processes below would be responsible?
