NDT Inspections

Gator Rigging offers the following for steel, aluminum, and stainless steel parts:

  • Magnetic Particle Testing
  • Dye Penetrant Testing
  • Visual Testing
  • Ultrasonic Testing & Inspection

Our technicians have undergone a rigorous training course and have been certified by a third party in order to provide you with the most accurate analysis of your part.

Magnetic Particle Inspection (MT) detects discontinuities in ferrous metals by applying a magnetic field to the part. Then a wet or dry magnetic flux is applied to the part. The flux is attracted to discontinuities and begins to build up at the discontinuity which is known as an indication. The indication can then be evaluated to determine what it is, what may have caused it, and what action should be taken, if any.

Dye penetrant inspection (DPI), also called liquid penetrant inspection (LPI) or penetrant testing (PT), is used to locate surface-breaking defects in aluminum and stainless steel. The penetrant may be applied to all non-ferrous materials and ferrous materials, although for ferrous components magnetic-particle inspection is often used instead for its subsurface detection capability. LPI is used to detect casting, forging and welding surface defects such as hairline cracks, surface porosity, leaks in new products, and fatigue cracks on in-service components.

Ultrasonic Testing (UT) is often performed on steel and other metals and alloys. It uses very short ultrasonic pulse-waves with center frequencies ranging from 0.1-15 MHz and occasionally up to 50 MHz are launched into materials to detect internal flaws or to characterize materials. A common example is ultrasonic thickness measurement, which tests the thickness of the test object, for example, to monitor pipework corrosion.
