Q1 QUESTION 1 OF 48
There is a weld that was bent outside the bend radius of the shoe and no fracture on the bend. what should be
done when this is noted?
CORRECT ANSWER
Cut another specimen from the original specimen and bend it.
RATIONALE
The specimen was bent outside the specified radius, invalidating the bend test and indicating the need for a new
specimen to ensure a valid assessment of weld ductility. This procedure verifies that the weld material itself meets
the required bend properties.
Q2 QUESTION 2 OF 48
which of the following conditions shall cause inadequate penetration (IP) to be considered a defect?
CORRECT ANSWER
The length of an individual indication of IP exceeds 1 inch.
RATIONALE
Inadequate penetration is classified as a defect when its length exceeds 1 inch, indicating a significant failure in
fusion and potential structural compromise. This threshold signifies a critical deviation from acceptable weld quality
standards.
Q3 QUESTION 3 OF 48
Page 2
, Cracked welds shall be cut out unless the repair is authorized by the company. when a crack repair is
authorized for pipeline:
CORRECT ANSWER
A double repair of a crack is not permitted
RATIONALE
Pipeline crack repairs require specific authorization and prohibit double repairs to maintain structural integrity and
prevent catastrophic failure. This rule emphasizes the critical nature of weld integrity in high-pressure systems.
Q4 QUESTION 4 OF 48
Arc burns on the parent metal shall not exceed ________ in length?
CORRECT ANSWER
never accepted, regardless of their length
RATIONALE
Arc burns on the parent metal are considered defects because they can initiate cracks and compromise the
structural integrity of the material, and are therefore never accepted regardless of their length. This question tests
understanding of welding quality standards and defect acceptance criteria.
Q5 QUESTION 5 OF 48
True or False: according to Clause 3 (Pipeline), cluster porosity shall be considered a defect if the diameter of
the cluster exceeds 1/2 inch?
CORRECT ANSWER
True
RATIONALE
The standard for pipeline integrity defines cluster porosity as a defect when its diameter surpasses the 1/2-inch
threshold, directly addressing potential material weaknesses. This clause establishes a quantifiable limit to ensure
structural soundness in pipeline construction.
