Practical Exercise · Liquid Penetrant Testing
Inspect a welded plate — solvent removable, visible dye
Scope: perform PT on the butt weld below and evaluate any indications.
Area of inspection: the entire weld length plus 1 inch on either side of the weld to cover the heat-affected zone (HAZ). It is marked on the plate.
- Pick a spray can from the tray, then press and hold on the plate and drag along the weld to spray.
- Rags wipe the same way — select, then press and drag.
- One step is shown at a time. If you reach for the wrong thing, you'll get a nudge, not a penalty.
Dwell timers are accelerated: 30 s runs in ~10 s, 5 min runs in ~40 s. In the real shop you wait the full time.
