Red Seal Ironworker (Generalist) Practice Exam

What type of inspection should be performed on welds?

1. Visual inspection only

2. Non-destructive testing only

3. Visual inspection and non-destructive testing

4. Paperwork review and certification

The correct answer is: Visual inspection and non-destructive testing

Weld inspections play a crucial role in ensuring the integrity and quality of welds, which are essential for structural safety in ironworking. The combination of visual inspection and non-destructive testing provides a comprehensive assessment of weld quality. Visual inspection is the first step, where inspectors look for visible defects, such as improper welding technique, lack of penetration, and surface cracks. This method is fast and allows for immediate identification of obvious problems. Non-destructive testing (NDT) complements visual inspection by detecting subsurface defects that are not visible to the naked eye. Methods such as ultrasonic testing, radiographic testing, and magnetic particle testing are commonly used in NDT to identify flaws that could compromise the weld's integrity without damaging the material. Performing both visual inspections and non-destructive testing ensures a thorough assessment, increasing confidence in the weld's ability to perform under load and environmental conditions. This dual approach is essential for maintaining safety standards and meeting industry regulations. While paperwork review and certification confirm that procedures and qualifications are met, they do not replace the need for actual physical inspection of the welds to guarantee their quality and integrity.
