Ultrasonic Testing Level-I

Training course objective:

To provide a basic knowledge of UT to enable a participant to carryout tests according to an established procedure under the supervision of a level II or level III personnel. The course is especially designed to provide a sound theoretical knowledge and practical skill for UT required for a Level I  technician

UT Level I Responsibilities

To carryout operation as per written procedure/instruction from Level II personnel. He shall be able to set up the equipment, calibrate and carryout the tests, classify and report the results. He shall not be responsible for the choice of the test technique nor for assessment of the test results.

UT Level I Course outline

Ultrasonic Testing Level-II


Training course objectives

The course is intended to provide through grounding in the principle of Ultrasonic Testing-UT and fundamentals of material and process such that the trainee would be able to

  • Identify suitability of UT for the material and inspection technique
  • Develop techniques and procedures that can be followed by a Level I operator
  • Analyse the test result and document the same
  • Be familiar with codes, standards and specifications for UT to evaluate results of the tests


UT Level II Responsibilities

A certified UT Level II  personnel is qualified to

  1. Select proper test technique, equipment and probes
  2. Set up and calibrate the equipment
  3. Perform testing and interpret the results as per applicable standards
  4. Have knowledge of the scope and limitations of UT
  5. Be familiar with production processes of the test material and knowledge of type and location of expected defects
  6. To develop UT technique for testing a particular job
  7. Prepare test report for i. Accept ii. Reject iii. Rework
  8. Prepare written instruction for Level I
  9. Guide and check test results of Level I operators
  10. Responsible for care and maintenance of the NDT/UT equipment
