Questions and Answers | Latest Version
| 2024/2025 | Correct & Verified
How can incomplete fusion be identified?
✔✔ By observing a lack of bonding between the weld metal and the base metal or between weld
passes.
What is the purpose of using dye penetrant testing on a weld?
✔✔ To detect surface cracks and other discontinuities that may not be visible to the naked eye.
What is the significance of a welding procedure specification (WPS) during inspection?
✔✔ It ensures that the welding process is performed according to the approved guidelines.
Why is it important to control welding heat input?
✔✔ To avoid excessive distortion or weakening of the weld and base metal.
What does excessive spatter indicate about the welding process?
✔✔ It suggests incorrect settings or poor technique.
1
, What is the role of a certified welding inspector (CWI)?
✔✔ To assess and ensure the quality of the weld meets all applicable standards.
What is the primary purpose of a welding inspection?
✔✔ To ensure the weld meets specified quality and design standards.
Why is visual inspection important in welding?
✔✔ It allows for the identification of surface defects such as cracks, porosity, or incomplete
fusion.
When should a visual inspection typically be performed during the welding process?
✔✔ Before, during, and after welding.
What is a weld discontinuity?
✔✔ An irregularity in the weld that may or may not affect its performance.
What is the difference between a weld defect and a discontinuity?
