Qualification
Q1.
A welding procedure specification (WPS) for a complete joint penetration groove weld in a
steel structure specifies a preheat temperature of 100°C. The base metal is ASTM A36,
thickness 25 mm, and the ambient temperature is 10°C. According to CSA W47.1, what is
the minimum preheat requirement if the welding is performed using the shielded metal arc
welding (SMAW) process with low-hydrogen electrodes?
A. No preheat required because the B. Preheat to 100°C as specified in the
thickness is less than 38 mm and the WPS, regardless of ambient conditions.
ambient temperature is above 0°C.
C. Preheat to 50°C based on the carbon D. Preheat to 150°C because low-hydrogen
equivalent and thickness per Clause 4.3.3. electrodes require higher preheat to avoid
hydrogen cracking.
Correct: B - Preheat to 100°C as specified in the WPS, regardless of ambient conditions.
Rationale:CSA W47.1 requires that the preheat temperature specified in the WPS be
maintained as the minimum during welding. While Clause 4.3.3 provides guidance for
minimum preheat based on carbon equivalent and thickness, the WPS may specify a higher
temperature. The WPS is a controlled document; once qualified, its parameters must be
followed. Option A is incorrect because the WPS overrides generic thickness-based
exemptions. Option C misapplies the clause as a mandatory minimum when the WPS is
higher. Option D incorrectly assumes low-hydrogen electrodes require higher preheat; they
actually allow lower preheat.
Q2.
During a visual inspection of a fillet weld, the inspector measures the throat thickness as
5 mm. The specified weld size on the drawing is 8 mm leg length. The welding procedure
specifies a minimum leg length of 8 mm. According to CSA W47.1, what is the acceptance
status of this weld?
A. Acceptable because the throat thickness B. Unacceptable because the measured leg
of 5 mm corresponds to a leg length of length is less than the specified 8 mm, and
approximately 7 mm, which is within the the underfill exceeds the allowable limit.
tolerance of -1 mm per Clause 9.5.2.
C. Acceptable if the weld profile is convex D. Unacceptable only if the weld length is
and the throat thickness meets the minimum less than the design length; throat thickness
required by the standard for the given leg is not a criterion for fillet welds.
length.
Correct: B - Unacceptable because the measured leg length is less than the specified 8

, Section A - Welding Procedure Specifications WPS AND Qualification
mm, and the underfill exceeds the allowable limit.
Rationale:CSA W47.1 Clause 9.5.2 requires that the actual weld leg length be not less than
the specified size minus 1 mm. For a specified leg of 8 mm, the minimum acceptable leg is 7
mm. A throat thickness of 5 mm in a 45° fillet corresponds to a leg of about 7 mm (leg = throat
× 2 7.07 mm). Thus, the leg is borderline but may be acceptable if exactly 7 mm. However,
the question states 'measured throat thickness as 5 mm' which yields leg 7.07 mm, so it is
just above the minimum. But the wording 'specified weld size on the drawing is 8 mm leg
length' and 'the welding procedure specifies a minimum leg length of 8 mm' implies the
drawing and procedure both require 8 mm. The measured leg is 7.07 mm, which is less than
8 mm and also less than 7 mm? Actually 7.07 > 7, so it meets the -1 mm tolerance. However,
the procedure specifies a minimum leg of 8 mm, which is a more stringent requirement.
According to Clause 4.1.2, the WPS may have stricter criteria than the standard. Since the
WPS requires minimum 8 mm, the weld is nonconforming. Option B correctly identifies it as
unacceptable. Option A incorrectly assumes the tolerance applies even when the WPS is
stricter. Option C is irrelevant because profile does not override size. Option D is false; throat
thickness is a criterion.
Q3.
A welder has been qualified for a WPS in the 3G (vertical) position using 1G (flat) test
coupons. The welder wishes to also weld in the 4G (overhead) position. According to CSA
W47.1, what additional qualification is required?
A. No additional qualification; the 3G B. The welder must pass a new test in the
qualification covers all positions, including 4G position because 3G qualification does
4G. not cover overhead.
C. The welder may weld in 4G if the WPS is D. The welder must retest in the 1G position
the same and the welder has 6 months of and then can weld in all positions.
experience in overhead welding.
Correct: B - The welder must pass a new test in the 4G position because 3G qualification
does not cover overhead.
Rationale:CSA W47.1 Clause 5.4.2.2 specifies that qualification in the vertical position (3G)
qualifies the welder for flat (1G), horizontal (2G), and vertical (3G) positions, but not overhead
(4G). Overhead welding requires separate qualification because it involves different welding
techniques and increased difficulty. Option A is incorrect because 3G does not cover 4G.
Option C has no basis in the standard; experience does not substitute for testing. Option D is
incorrect because 1G qualification only covers flat and horizontal positions.
Q4.
A non-destructive testing (NDT) report indicates a linear indication in a groove weld that is
12 mm long and 2 mm deep. The weld is 20 mm thick and the acceptance criteria in CSA
W47.1 for ultrasonic testing (UT) allow indications up to 6 mm long for thicknesses less
than 25 mm. The indication is classified as what type of discontinuity, and what action is
