PHASED ARRAY ULTRASONIC TESTING

PCN Level 3- Phased Array Ultrasonic Testing

Duration: 5days (35 Hours)

Course Overview:

The coursed is designed to provide guidance for preparing PAUT LEVEL 3 examination as per PCN requirements for welds sector. The aim of this course is to ensure candidates understood the scope of the examination, theory concepts and procedure requirements as per CP 25.   On arrival, Mock test on the method is conducted and gap analysis report is prepared based on the outcome of mock test. This will also enable candidates to identify their weak subject areas. Training duration is decided based on the weak areas and candidate requirement.
