Use questions before passive review

Start with a short set, mark the misses, then review the exact topic that caused the miss. This keeps study time tied to evidence from your own answers instead of a vague topic list.

Sample 1

What is the main job of a welding inspector?

  1. Accept welds whenever their surface appearance is uniform
  2. Change the qualified procedure to match completed production work
  3. Base acceptance on production urgency instead of governing criteria
  4. Evaluate welds against applicable requirements and documentation

Answer: D. Inspection work involves comparing observations and records against applicable requirements.

Sample 2

How should an inspector use a welding symbol during visual inspection?

  1. Compare the completed weld's side, type, dimensions, contour, and supplementary requirements with the drawing
  2. Treat the tail as the arrow-side indicator for every symbol
  3. Use the symbol as proof that the weld is acceptable without examination
  4. Ignore dimensions once the basic weld type is recognized

Answer: A. A welding symbol communicates specified weld requirements that must be compared with the completed work.
