Non-Destructive Testing

The nondestructive test unit evaluates the soundness of parts to specific accept/reject criteria through various nondestructive testing (NDT) methods. These test methods allow technicians to examine the part for discontinuities without destroying it.

Products manufactured at RIA-JMTC are submitted to NDT early in production. The NDT unit examines castings, weldments, forgings and machined parts for discontinuities and evaluates to appropriate acceptance criteria. Frequent interaction between NDT and various other departments occurs to ensure that problems are addressed early in production and corrections are implemented.

This area contains a high energy x-ray machine that is capable of imaging film through 14 inches of steel. Along with lower energy units, this capability allows NDT technicians to examine the interior of castings and weldments for discontinuities. Automatic film processing units ensure immediate results.

The technicians in this area are highly qualified. They have earned degrees in nondestructive testing technology and are centrally (third party) certified through the American Society for Nondestructive Testing. Two technicians are ASNT ACCP Professional Level III's in various testing methods. Two specialists have attained Certified Welding Inspector (CWI) status through The American Welding Society. Certifications meet the ISO international standard for NDT personnel certification.

NDT Certifications:

  • ASNT ACCP NDT Professional Level III Technicians
  • Level III procedure preparation/ approval
  • ASNT ACCP NDT Level II training
  • AWS Certified Welding Inspector (CWI)

NDT Testing Methods

  • Radiographic testing- used to evaluate internal discontinuities.
  • Magnetic particle- used to evaluate surface to near surface discontinuities in ferromagnetic materials.
  • Liquid penetrant testing- used to evaluate open to the surface discontinuities.
  • Ultrasonic testing- used to evaluate internal discontinuities.
