SECTION 1: CSA W47.1 - CERTIFICATION OF WELDING COMPANIES
(Questions 1-50)
1. What is the primary scope of CSA W47.1?
A) Certification of individual welding inspectors for all materials.
B) Certification of companies engaged in the fusion welding of steel structures.
C) Qualification of welding consumables for structural steel applications.
D) Design and calculation requirements for welded steel connections.
Correct Answer: B
Rationale: CSA W47.1 is explicitly titled "Certification of Companies for Fusion
Welding of Steel." Its entire structure is built around the requirements a company
must meet to obtain and maintain certification, covering personnel (engineers,
supervisors, welders), documented welding procedures, and quality control
systems. It does not cover inspector certification (that is CSA W178.2) or design
(that is CSA S16 and W59, Clause 2).
2. How many distinct classes of welding company certification are defined in CSA
W47.1?
A) Two (Certified and Non-Certified)
B) Three (A, B, C)
C) Four (A, B, C, D)
D) Five (A, B, C, D, E)
Correct Answer: C
Rationale: W47.1, Clause 4.1, establishes four certification classes: A, B, C, and D.
This grading system allows the standard to apply to a wide range of fabrication
1
,scenarios, from complex, engineer-heavy projects (Class A) to simpler, limited-
scope work (Class D), each with proportionally scaled oversight requirements.
3. What is the fundamental personnel difference between a CSA W47.1 Class A
and Class B certified company?
A) Class A must have an on-site CWB Level 3 Inspector; Class B needs a Level 2.
B) Class A requires a full-time Professional Engineer (Welding Engineer); Class B
requires a full-time Welding Supervisor and a part-time/consulting Welding
Engineer.
C) There is no difference; Class A simply allows for thicker material welding.
D) Class A companies can weld all steel grades; Class B is limited to 350 MPa yield
strength.
Correct Answer: B
Rationale: The key distinction lies in engineering oversight. A Class A company
(W47.1 Clause 4.2.1) must employ a full-time welding engineer. A Class B
company (Clause 4.3.1) must have a full-time welding supervisor and retain a
welding engineer on a part-time or consulting basis. This ensures Class B shops
have access to high-level technical support without the burden of a full-time
position, fitting mid-sized operations.
4. What is the minimum qualification for a full-time Welding Engineer in a CSA
W47.1 certified company?
A) A valid CWB Level 3 Welding Inspector certification.
B) A four-year Bachelor's degree in any engineering discipline from a recognized
university.
C) A Professional Engineer (P.Eng.) license valid in the province of operation, OR
meeting the specific education and experience requirements of W47.1 Appendix
A.
D) An American Welding Society (AWS) Certified Welding Engineer (CWEng)
credential.
Correct Answer: C
Rationale: W47.1 Clause 4.2.2 states the welding engineer must be a Professional
Engineer licensed to practice in the province where the work is performed. As an
2
,alternative path, Appendix A provides a detailed matrix of acceptable education
(e.g., a 4-year degree in engineering or physical sciences) combined with a
specified number of years of direct, documented welding experience to achieve
equivalency.
5. Under CSA W47.1, who is directly responsible for the day-to-day supervision of
welders and ensuring they follow the qualified Welding Procedure Specifications
on the shop floor?
A) The company's President or CEO.
B) The Welding Engineer.
C) The Welding Supervisor.
D) The CWB Level 2 Welding Inspector.
Correct Answer: C
Rationale: W47.1 Clause 4.4 defines the roles and responsibilities of the welding
supervisor. This person is the front-line manager responsible for assigning work,
ensuring welders are qualified for the tasks they perform, verifying that the
correct WPS is available and being followed, and managing the overall welding
operation's workflow and quality.
6. What is the minimum record retention period for a welder's qualification test
records after that welder's employment has been terminated?
A) 6 months from the date of termination.
B) 1 year from the date of termination.
C) 2 years from the date of the last test.
D) Records must be kept permanently for the life of the company's certification.
Correct Answer: B
Rationale: As per W47.1 Clause 11.2.2, the certified company must retain all
records of a welder's qualification tests for at least one year after the welder's
employment with the company has ceased. This ensures traceability for projects
completed during the welder's tenure. While a company holds certification, these
records are a critical auditable component of its quality management system.

, 7. A welder is qualified on a plate test in the 3G and 4G positions according to
W47.1. For which of the following pipe positions is this welder qualified to weld?
A) All pipe positions (1G, 2G, 5G, 6G).
B) 1G (flat rolled) and 2G (horizontal) only.
C) 5G (horizontal fixed) and 6G (45-degree fixed) only.
D) None; a separate pipe qualification test is mandatory.
Correct Answer: D
Rationale: W47.1 is very clear in Clause 9.4.2.1 that qualifications for plate and
pipe are separate and distinct. A test on plate qualifies the welder only for plate
production welding. To weld on pipe, the welder must perform a specific
qualification test on pipe, as the variables like diameter restriction, wall thickness
transitions, and welding techniques differ significantly.
8. What is the maximum allowable period of inactivity where a welder does not
use a specific welding process before their qualification for that process lapses
automatically?
A) 3 months
B) 6 months
C) 1 year
D) 2 years
Correct Answer: B
Rationale: W47.1 Clause 9.8.1 states that a welder's qualification for a process is
considered expired if more than six months have lapsed since the welder last
used that specific process. The company must maintain records, often called
continuity logs, to prove each welder has been actively engaged in welding with
their qualified processes. If the period exceeds 6 months, requalification is
necessary.
9. A company's welding supervisor has resigned. Per W47.1, what is the maximum
time a certified company can operate without a qualified replacement welding
supervisor before its certification is at risk?
A) 14 days
B) 30 days
