Type of radiation used, whether x-rays from an x-ray generator or gamma rays from a radioactive source. Kilovoltages available with the x-ray equipment or the intensity of the gamma radiation. Relative importance of high radiographic detail or quick and economical results.
Laser Testing Methods (LM) Laser testing includes three techniques: Holography, Shearography and Profilometry. All three techniques use lasers to perform the inspections. Laser NDT methods based on interferometic imaging, primarily holography and shearography have seen growing acceptance since the mid 1980’s. With a large increase in the use of composite materials and sandwich structures ...
Magnetic Particle Inspection (MPI) also sometimes called as Magnetic Test (MT) is a non-destructive test method for the detection of surface and sub-surface discontinuities in ferrous materials. The test method involves application of magnetic field externally or applying electric current through the material which in turn produces magnetic flux in the material.
Radiographic Testing (RT or X-ray or Gamma ray) is a non-destructive testing (NDT) method that examines the volume of a specimen. Radiography (X-ray) uses X-rays and gamma-rays to produce a radiograph of a specimen, showing any changes in thickness, defects (internal and external), and assembly details to ensure optimum quality in your operation.
Basic Principles of Ultrasonic Testing Ultrasonic Testing (UT) uses high frequency sound energy to conduct examinations and make measurements. Ultrasonic inspection can be used for flaw detection/evaluation, dimensional measurements, material characterization, and more.
