2. Phased Array Ultrasonic (UTPA)

Phased array ultrasonic (PA) is an advanced method of ultrasonic testing that has applications in medical imaging and industrial nondestructive testing. Common applications are to noninvasively examine the heart or to find flaws in manufactured materials such as welds. Single-element (non-phased array) probes, known technically as monolithic probes, emit a beam in a fixed direction.

To test or interrogate a large volume of material, a conventional probe must be physically scanned (moved or turned) to sweep the beam through the area of interest. In contrast, the beam from a phased array probe can be focused and swept electronically without moving the probe. The beam is controllable because a phased array probe is made up of multiple small elements, each of which can be pulsed individually at a computer-calculated timing.

The term phased refers to the timing, and the term array refers to the multiple elements. Phased array ultrasonic testing is based on principles of wave physics, which also have applications in fields such as optics and electromagnetic antennae.

PCN Level 1 & 2

This course is designed to provide the participants, a better understanding about theory and application of phased array ultrasonic testing, to train them and qualify them as PCN Level I & II in phased array ultrasonic testing.

PCN Level 3

This guidance course is aimed at the PCN Level 3 requirements for PAUT practitioners. The main objective of the course is to make candidates fully aware of the scope of the examination and level of knowledge required. It will also enable candidates to identify their weak subject areas. Advice will be given on any further tuition required.

Training Hours

Level 1	Level 2	Level 3
40 Hrs	80 Hrs	40 Hrs
Direct access to Level 2 requires the total hours shown in table for Levels 1 and 2

Experience

Level 1

Level 2

Level 3

1 months

3 months

24 months

Note-1: For Level 2 certification, the intent is that work experience consists of time as a Level 1. If the individual is being qualified directly to Level 2, with no time at Level 1, the experience shall consist of the sum of the times required for Level 1 and Level 2. No reduction in the period of experience shall be allowed

Note-2: Industrial NDT experience in the appropriate sector may be acquired either prior to or following success in the qualification examination.

• PSL 57-A Initial Examination application
• PSL 30- Log of Experience
• PSL 44-Vision Requirements (which has to be certified by a registered medical practitioner)
• CP-27 code of ethics
• PCN ID (wallet or e-certificate) -only for existing PCN certificate holders
• PCN UT level I Certificate copy (If applicable)
• One govt approved identity card (example: Passport/voter ID /Aadhaar Card)
