Course Overview

This blended PAUT Level 2 programme prepares candidates for PCN and ASNT qualification in phased array ultrasonic testing. Theory modules are delivered online, covering phased array physics, equipment operation, focal laws, and data interpretation. Practical training and examination are conducted on-site. The programme is designed for NDT professionals working in oil and gas, pipeline, power generation, pressure vessel, and structural inspection environments where PAUT is specified under ISO 9712, PCN, or ASNT SNT-TC-1A.

Who Should Attend

NDT technicians holding UT Level 1 or Level 2 qualification seeking PAUT Level 2 certification
Inspection engineers and supervisors responsible for PAUT inspection programmes
Pipeline and pressure equipment inspectors working under PCN or ASNT qualification schemes
Quality assurance personnel specifying or reviewing PAUT procedures
Prerequisites

UT Level 1 or Level 2 qualification under ISO 9712, PCN, or ASNT SNT-TC-1A. Minimum documented UT industrial experience as required by the applicable qualification scheme.

Learning Outcomes

  • Explain phased array ultrasonic physics, beam steering principles, and array element operation
  • Set up and operate PAUT instruments, probes, wedges, and calibration reference blocks
  • Develop focal laws for linear, sectorial, and compound scanning configurations
  • Apply PAUT scanning procedures to weld inspection and corrosion mapping applications
  • Acquire, display, and interpret PAUT data in A-scan, B-scan, C-scan, and S-scan formats
  • Detect, characterize, and size flaws using accepted sizing techniques
  • Produce compliant inspection reports and documentation
  • Demonstrate knowledge of applicable codes and qualification requirements under ISO 9712 and ASNT SNT-TC-1A
