Phased Array (PA)

Ensure component quality time and cost effectively

Phased array (PA) is widely used in several sectors, from power generation to construction industries. It is an advanced non-destructive testing (NDT) method that uses an ultrasonic technique to determine component quality and detect failure such as flaws or cracks. Furthermore, it can be effectively used for wall thickness measurements in conjunction with corrosion testing. Its efficiency comes from the combination of many angles and focus depths through to one probe which then performs several different inspections without the need for changing the transducer assembly. The inspection results are clearly stored and displayed for reporting. It can be used on standard and special materials like austenitic and high alloy materials.

Benefits of phased array at a glance

Using TÜV Rheinland phased array inspection services, you gain:

  • Simplified inspection of components that have complex geometry.
  • Inspection of many different materials possible.
  • High temperature inspections possible up to over 350°C.
  • Speedy inspection compared to conventional ultrasonic testing.
  • Higher probability of problem detection thanks to testing from multiple angles with a single probe.
  • All inspection data presented in an understandable graphic format.
  • Well qualified operators.
  • TÜV Rheinland´s exclusive one-stop shop services.

Our phased array inspection follows this procedure

  • Multiple ultrasonic elements and time delays create beams.
  • Software controls beam angle and focus.
  • Eco information is set together to form a visual image.

Phased array application range

  • Everywhere, where conventional ultrasonic testing has been used.
  • Weld inspection
  • Crack and flaw detection
  • Thickness measurements
  • Corrosion inspections
