Practice set

1. Review PT Principles

Why must a part be fully dry after cleaning and before penetrant is applied?

Liquid left in openings takes up room that penetrant needs to fillLiquid left on the part lowers the flash point of the fresh penetrantLiquid left on the part makes the developer coat too thick laterLiquid left in openings turns the visible dye from red to pink

2. Selection of the Appropriate PT Method

A fluorescent part is put into a dry powder developer cabinet before the part has fully dried after rinsing. What is the likely result?

Powder dissolves into the water and forms a clear, even film over the partPowder clumps on damp spots, giving an uneven coat that can hide indicationsPowder is repelled by the moisture, so the damp areas stay bare and readablePowder reacts with the water and fluoresces blue, adding a general background

3. Inspection and Evaluation of Indications

A continuous line follows the full length of a fillet on a casting, with no break. Which feature best supports reading it as geometry rather than a crack?

It glows brighter than any other indication found on the castingIt bleeds back after a wipe and a fresh coat of developerIts even width and steady brightness along the whole radiusIts length is more than three times its measured width

4. Inspection and Evaluation of Indications

On a butt weld cap, a straight, fairly smooth line indication follows the edge of the bead where weld metal meets base metal. Which discontinuity fits best?

Crater crack at a stop in the weld beadTransverse crack running across the weld beadScattered porosity near an arc startLack of sidewall fusion open to the surface

5. Inspection Procedures and Standards

What is the main skin effect of repeated contact with penetrants and solvent removers?

The dyes are absorbed through the skin and build up as a long-term toxic doseOils are stripped from the skin, leading to dryness and dermatitisUV-A from the booth reacts with the dyes and burns the skinThe developer powder blocks skin pores and causes infections
