LIQUID PENETRANT INSPECTION

One of the most popular, non-destructive examination (NDE) methods in the industry, Cadorath’s technicians use this technique to check for material flaws. The process begins by flowing very thin liquid into the flaw, or fissure, and then drawing it out with a chalk-like developer. Components such as bars, pipes, plates, castings and forgings are commonly inspected this way but welds are the most prevalent. Cadorath uses the liquid penetrant method primarily for aerospace applications.

 

ADVANTAGES OF LIQUID PENETRANT INSPECTION

  • Very economical.
  • Versatile, can be applied to multiple materials.

 

ORIGINS AND DEVELOPMENT

The first documented use of liquid penetrant testing was in the railroad industry. Cast railroad wheels were often dipped in used oil, dried off, and then coated with powder chalk or suspension of chalk in alcohol. Once dry, any oil stored in the flaw would bleed out into the chalk and be detected.

 

FUTURE APPLICATIONS

Over the years, many advances have been made to the application of liquid penetrant inspection processes, but the essence of the detection methods remain the same.
