PCN Ultrasonic Testing Welds ( UT 3.1 & 3.2 )

Similar to the ultrasonic principles used by an Obstetrics or Gynecology during pregnancy and naval SONAR, Ultrasonic testing uses the transmission of high frequency sound waves, into a material to detect imperfections within the material or changes in material properties. If the sound traveling through a Material hits material with different acoustical impedance, some of the sound will reflect back and received by the Ultrasonic testing unit and will be represented as an indication on the screen. Knowing the velocity at which sound travels through a part, along with the time of travel will result in a distance to the indication (material with a change in acoustic impedance).

Sound waves are introduced to the part via a transducer made up of a piezoelectric crystal that converts electrical current to sound waves and reflected sound waves to electric current. The two most commonly used types of sound waves are Compression (Longitudinal or Straight Beam) and Shear wave (Transverse or Angle Beam).

NDTS India (P) Ltd is your one stop shop for PCN UT level II in Mumbai.

Advantages of Ultrasonic Testing techniques:

  • Detects defects throughout volume
  • Portability
  • Consistent
  • Only limited access needed
  • Non hazardous
  • Instant results

Limitations of Ultrasonic Testing Techniques:

  • Comparatively extensive training required
  • Expensive compared to other methods
  • Limited applications in thin materials
  • Difficulties in complex part geometry
  • Needs relatively smooth surface to couple transducer
  • Calibration block and other parameters are required for equipment set-up

It is evident from the observations above that Ultrasonic Testing training is a great idea. NDTS facilitates an in depth PCN Ultrasonic testing training course. We conduct ultrasonic testing classes and our sole aim is that the trainee should receive QUALITY ultrasonic Testing training.

A PCN UT Level II Training at NDTS is an excellent first step to mastery in ultrasonic testing techniques and a trainee would be able to immediately see the benefits in ultrasonic testing. Ultrasonic testing form the core of NDTS methods. Some of the other courses offered are PCN PAUT Level II, PCN TOFD Level II

Responsibilities of Certified UT Level II

An individual certified to UT Level II has demonstrated competence to perform NDT according to Ultrasonic Testing procedures. Within the scope of the competence defined on the certificate, Level 2 personnel may be authorized by the employer to:

  • Select the Ultrasonic technique for the test method to be used;
  • Define the limitations of application of the testing method;
  • Translate NDT codes, standards, specifications and procedures into NDT instructions adapted to the actual working conditions;
  • Set up and verify equipment settings;
  • Perform and supervise tests;
  • Interpret and evaluate results according to applicable standards, codes, specifications or procedures;
  • Carry out and supervise all tasks at or below level 2;
  • Provide guidance for personnel at or below level 2;
  • Report the results of Ultrasonic test.

Days & Duration of UT Courses

15 Days Course for UT Welds suitable for PCN Level 2 Direct (120 Hours)

UT Course will cover following

General Theory

  • Principles of Ultrasonic Testing
  • Equipment
  • Testing techniques
  • Calibration of testing systems

Sector Specific Theory

  • Detectability of defects
  • Factors affecting the performance of the Ultrasonic test
  • Codes of practice and standards
  • Conducting and recording the test
  • Interpretation of test results
  • Product technology theory

The PCN requirements of Training Hours & Work Experience for Level 2 PA are

80 hours training if Level 1 is held, or 120 hours direct to level 2, previous to the exam, and 9 months supervised work experience additional to Level 1 (12 months direct), to be obtained either before the examination, or within 24 months after passing the exam.

Once the 80 additional hours training have been obtained, the examination passed, and 9 additional months supervised work experience obtained within 24 months of passing the exam, PCN will issue certification.

Following documents are required for PCN Examination
