What is an FPI inspector?

FPI Inspectors, or Fluorescent Penetrant Inspection Inspectors, are professionals who perform non-destructive testing (NDT) to detect surface defects in materials, most commonly metals. They use a special fluorescent dye that penetrates into surface cracks or flaws, and then use ultraviolet light to make these flaws visible. FPI Inspectors play a crucial role in quality assurance, particularly in industries like aerospace, automotive, and manufacturing, where safety and reliability are paramount. Their work helps ensure that components meet strict safety and performance standards before being put into service.
