Phased Array Inspections

Phased Array Inspection of Seam and Girth Welds:

​

TKS staff have the qualification and experience to perform phased array ultrasonic testing (PAUT) and time-of-flight diffraction (TOFD) on power piping seam and girth welds to find service-related weld and heat-affected zone (HAZ) flaws.  Scanning can be performed manually or with an automated scanner.  Used PAUT and TOFD to find lack of fusion, slag, center line cracks, transverse cracks, base metal cracks, heat-affected zone cracks, and other critical flaws.
