Time of Flight Diffraction (TOFD)Level II Online Courses

ASNT TOFD Level II Course Training and certification fee is $500

Course Contents:

 This course focuses on the theory and principles of ultrasonic and advanced ultrasonic technologies – TOFD theory and principles of diffraction – TOFD technique – TOFD equipment and probes – principle of TOFD  inspection; software familiarization – preparation of scan plans – TOFD inspection calibrations and optimising PCS and angles – data scanning with TOFD probes; TOFD data acquisition and interpretation, analysis; use of software tools for defect detection, flaw location and sizing; data analysis; Interpretation & Evaluation – acceptance Criteria – limitations of detection and resolution – procedures for verification of flaw existence and position; reporting; TOFD applications – welding processes and weld defects – number of practical exercises on test specimens containing simulated flaw

This 80-hour course exceeds the instruction outline and criteria specified in the ASNT Recommended Practice SNT-TC-1A, ANSI/ASNT CP-189 and ASNT Standard Topical Outlines for Qualification of Non-destructive Testing Personnel (ANSI/ASNT CP-105).

Time of Flight Diffraction (TOFD) theory classes will be organized through online and/or offline and hand-on practical section will be arranged nearest feasible NDT test center.

 Course Objectives:

The course objectives are as below:

  • To understand the theoretical background and limitations of TOFD applications.
  • To correctly select probe and wedge to examine welded butt joints.
  • To calibrate and set up the TOFD ultrasonic equipment.
  • To locate and evaluate flaws in the weld body and HAZ.
  • To understand and apply digital processing processes (SAFT, linearization, averaging, filters etc).
  • To analyse scan data for location and size of defects in typical welded butt joints.
  • To characterization and accurately report weld condition.
  • To interpret and evaluate the test result as per international applicable codes & standards
