NonDestructive Testing

Superior Joining Technologies, Inc. is an ASNT Level III NonDestructive Testing Facility. Our technicians have graduated from four-year colleges with degrees in engineering and science, plus decades of experience in NonDestructive testing to that of a Level III in the applicable test method(s) as defined by The American Society of NonDestructive Testing (ASNT).

NonDestructive Testing, also known as Non-Destructive Testing or NDT is a valuable technique because it does not permanently alter the item being inspected. NDT is also known by other terms such as NonDestructive Examination (NDE), NonDestructive Inspection (NDI), and NonDestructive Evaluation (NDE).

Fluorescent Penetrant Testing

Fluorescent Penetrant Dye Inspection

Fluorescent Penetrant Dye Inspection (Penetrant Testing or PT) is a widely accepted inspection method used to detect surface cracks and defects in metals, ceramics and plastics. Penetrant Inspection will detect casting and forging defects, cracks, micro shrinkage (or porosity) and leaks in new products, and fatigue cracks on in-service components.

Since May, 2007, Superior Joining Technologies has conformed to ASTM-E 1417 Standard Practice for Liquid Penetrant Inspection and was Nadcap Accredited in July, 2008.

Magnetic Particle Inspection

Magnetic Particle Inspection (MT) Continuous Wet Bench Method

Magnetic Particle Inspection (Magnetic Testing or MT) is a NonDestructive method for detecting defects in ferrous metals. A magnetic field created with AC or DC current is applied through the material, revealing flux leakage at surface or near-surface flaw.

Fine magnetic iron oxide particles, coated with a fluorescent dye and held in a suspension liquid, are attracted to the magnetic (flux) field in the area of the defect and to reveal it as a build-up of particles. The photograph at left shows an airplane crank-shaft being viewed with ultraviolet light (blacklight) as part of the magnetic testing process. The zoomed-view shows the presence of fatigue cracks on the plate around the crank shaft.

SJTI has the capability to test parts up to:

  • 6 inches in diameter
  • 90 inches in length
  • two tons in weight
