NDT Welding Exam: Practice Questions
and Answers| 2025/2026| Answered
What is the primary purpose of visual inspection in welding?
The primary purpose is to assess the external quality of a weld, ensuring it meets required
standards for appearance, size, and any visible defects.
What is the most common tool used during visual inspection of a weld?
A magnifying glass or welding inspection mirror is commonly used to examine small details
or hard-to-reach areas.
How can a welder ensure proper bead size during visual inspection?
The welder should ensure that the bead size meets the specifications laid out in the welding
procedure and is consistent along the length of the weld.
What type of defects are typically detectable through visual inspection in welding?
Defects such as cracks, undercuts, porosity, and improper bead profiles can be detected
through visual inspection.
What is the importance of lighting during visual inspection of a weld?
Proper lighting is crucial to ensure the inspector can clearly see surface defects, such as
cracks, undercuts, or porosity.

, What is the role of a weld inspection report in the visual inspection process?
A weld inspection report documents the findings of the inspection, including any defects or
discrepancies from the required welding standards.
What is the visual inspection procedure for checking the alignment of welded joints?
Inspectors visually check the joint alignment by examining the weld for any misalignment,
distortion, or gaps between the pieces being welded.
How can visual inspection help detect weld cracking?
By closely inspecting the weld surface for signs of fatigue or stress cracks, which may
appear as thin lines or fissures.
In what situations might a weld require rework based on visual inspection results?
If the weld shows defects such as excessive undercut, lack of fusion, or porosity, it may
require rework to meet the required standards.
What are the typical acceptance criteria for visual inspection of a weld?
Acceptance criteria generally focus on the size, shape, and overall appearance of the weld,
ensuring it meets specified tolerances and is free of visible defects.
What is the role of nondestructive testing (NDT) in welding?
