Penetrant Inspection

Testing, whether it is destructive or non-destructive, provides the end user a degree of confidence that the part that is being tested has no inherent flaws in it that may cause premature failure in its particular application. A stress crack in a part or a coating system that was not applied properly can have devastating results. Wolkerstorfer Company offers destructive testing, such as salt spray, cross hatch scribe testing and others to validate the coating systems we apply meet the applicable specifications.

Penetrant Inspection, also called Liquid Penetrant Inspection or Fluorescent Penetrant Inspection is a non-destructive method for testing a part for defects either in the wrought stage or after all the manufacturing and machining has been performed.

Typically used in nonferrous applications, Wolkerstorfer Company offers fluorescent penetrant inspection (FPI) that allows the inspector to see, under ultra-violet light, indications of possible defects that may be present in the material in its raw state or caused by the manufacturing process. We offer fluorescent dye (Type I), water washable (Method A) Sensitivity Level 2 and Sensitivity Level 3 with a number of qualified developers.

Wolkerstorfer Co. is also certified to provide the required pre-etch process prior to FPI, including Boeing and Rolls Royce. Meeting the requirements of the Federal Specification NAS 410, we conduct extensive training and testing for all of our certified personnel. We have three production lines so we can accommodate very small parts or components up to 30 feet in length. We are proud to say we are Nadcap certified.

The FPI lines, including the pre-etch, are Nadcap certified (AC7114).
