Nondestructive Testing

Nondestructive testing (NDT) identifies defects before they become problems, without destroying the sample material. Stork NDT services are designed to comply with government contracts, military specifications, industry standards, and your requirements; tests are timely, accurate and confidential, and are available in our labs or at your site.

Radiography  Using radioactive isotope (x-rays or gamma rays) a film is created, which we process in our laboratory or mobile darkroom. The results show defects which might otherwise be invisible. A vast array of material can be examined this efficient and reliable way—ranging from tiny electronic components to 20' freestanding concrete slabs.

Magnetic Particle For ferromagnetic materials such as castings, weldments, turbine components, forgings, and machined or stamped parts, this is one of the most sensitive examinations. The sample is magnetized, and iron filings are applied, which adhere to any breaks in the magnetic field. Defects too small to be visible can be further examined with fluorescent inspection.

Dye or Liquid Penetrant Stork scientists and technicians apply dye to a sample and then examine it visually or under fluorescent light to locate defects. This is a quick, economical testing method and easily set up in the field with our portable equipment.

Ultrasonic With this method, NDT inspectors only need access to one side of a material. A transducer sends the ultrasound through the sample and the inner wall of a defect surface will send the wave bouncing back. Ultrasonic testing can also measure thickness, detect corrosion, and examine groove welds, and it’s also very portable and efficient.
