Practice focus: Fundamentals, symbols, destructive testing, NDE methods, discontinuities, and acceptance logic.

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.

Sample 3

Which welding discontinuity is made of gas cavities in weld metal?

  1. Overlap
  2. Porosity
  3. Arc strike
  4. Undercut

Answer: B. Porosity is trapped gas in the weld metal and is commonly described as rounded cavities.

Sample 4

Which NDE method uses high-frequency sound to evaluate internal reflectors?

  1. Liquid penetrant testing
  2. Magnetic-particle testing
  3. Ultrasonic testing
  4. Visual testing
