Products & Services
Phased Array Ultrasonic Testing

Highlights of Phased Array:

  • Instant, accurate results
  • Minimal inspection time
  • Determine the exact depths of flaws
  • Detect surface and sub-surface imperfections
  • Encoded data
  • Mitigate safety risks
  • Code-compliant
  • All-digital data (eliminates boxes of film)
  • Meets API-650 code requirements
  • Now down to 1/4" material

Phased Array Ultrasonic Testing (PAUT) is an advanced nondestructive examination technique that utilizes a set of ultrasonic testing (UT) probes made up of numerous small elements, each of which is pulsed individually with computer-calculated timing. This technique can be used to inspect more complex geometries that are difficult and much slower to inspect with single-angle probes. PAUT can be used to inspect almost any material where traditional UT methods have been utilized and is often used for weld inspections and crack detection. 

Compared to other forms of UT, PAUT has several advantages. PAUT can be conducted more efficiently than other forms, often within a fraction of a second. It can easily be used for repeat scans because it has a high degree of repeatability. By emitting beams of multiple different angles sequentially, PAUT can create detailed and accurate cross-sections of a part. It is also particularly useful in situations where there is less room for mechanical scanning because it’s able to sweep the beam without moving the probe.

Advantages of radiography testing (RT) include:

  • No radiation source, eliminating boundaries and safety concerns
  • Immediate, real-time results
  • Precise location and sizing of defects, including width, length, depth, and overall size/volume
Shear Wave Ultrasonic Testing

Highlights of Shear Wave:

  • Ideal for structural inspection
  • Corrosion detection
  • Instant, accurate results
  • Mitigate safety risks
  • Code-compliant
  • Environmentally safe

Shear Wave Ultrasonic Testing (UTSW), also known as "angle beam inspection" is an ultrasonic technique that's great for weld and joint examination. A probe consisting of an ultrasonic transducer with a plastic or Lucite wedge introduces an angled beam into the test area that can be adjusted by the technician. As the probe is moved back and forth along the area under inspection, it can detect discontinuities in the weld based on the refraction of the ultrasonic beam.

Carbon steel and stainless steel in general, however, have excellent sensitivity compared to their penetration depth; therefore, shear wave modes are generated and applied in general ultrasonic tests.

UTSW is generally used in structural and bridge applications, however, it has a variety of benefits in numerous industries. While this method gives you real-time results, the data that is collected is not encoded, therefore it cannot meet certain code requirements. This is when PAUT is best utilized.

Magnetic Particle Testing

Magnetic Particle Testing (MT), also referred to as Magnetic Particle Inspection, is a non-destructive test (NDT) technique used to detect surface and slightly subsurface flaws in most ferromagnetic materials such as iron, nickel, and cobalt, and some of their alloys. Because it does not necessitate the degree of surface preparation required by other nondestructive test methods, conducting MT is relatively fast and easy. This has made it one of the more commonly utilized NDT techniques. MT can be applied in both visible and fluorescent applications.
