Penetrant Testing

Penetrant Testing

Slace inspections Ltd can supply Liquid Penetrant Inspection (LPI) or Fluorescent Penetrant Inspection (FPI) on-site as required. PT can be applied to almost any non-porous materials from welds to castings as seen in the photographs. The method of PT is to reveal any surface breaking indications through “bleed out” of a coloured dye from the flaw.

Fluorescent PT is based on the same principle; however, the conditions of the test are in darkened conditions with the aid of an Ultra Violet Light. This method is generally used for complex castings, machined parts or aerospace components.
