Ultrasonic Testing: Critical Defect Sizing

Why attend this course?

This programme is only available to holders of current PCN Level 2 Ultrasonic Practitioner Welds certification, which is applicable to at least two groups and held for at least 6 months. The course was developed to assist the technician/ engineer in the sizing of defects to within a tolerance level commensurate with the capabilities of the ultrasonic method. Originally designed to meet the objectives of the CEGB module: Defect Assessment for Fitness for Purpose Inspections - Ultrasonic Test Weld Samples. Now available as a PCN examination.


  • Production of beam plots for relevant probes
  • Practical examination of artificial simulations to assess plotting accuracy
  • Discussion of relevant normative documentation including BS and EN standards
  • Production of DAC and sensitivity levels
  • Discussion relating to echo-dynamic patterns
  • Reporting formats
  • Practical defect sizing on a variety of weldments
