Sonatest VEO Phased Array & TOFD - 101

The Sonatest VEO Phased Array and TOFD course reveals the balance achieved as both methods are demonstrated to complement each other. Practical exercises access a selection of engineered and actual flaw samples. The TOFD capabilities of the Sonatest instrument will be examined in detail, with emphasis on technique development and ASME code case 2235 implementation. We recommend that attendees have attained Level 2 or 3 certification in industrial ultrasonics and have a working knowledge of the Sonatest instrument prior to attending this course.

Topics

  • System calibration
  • Variable parameter inputs
  • Linear and sectorial scan definitions
  • Data acquisition and interpretation
  • System linearity assessment
  • Flaw location and sizing
  • TOFD theory and applications, including:
    • DAC, TCG
    • Optimizing PCS and angles
    • Limitations of detection and resolution
    • Dead zone coverage
    • Encoder calibration
    • TOFD calibration and optimization
    • TOFD analysis

Suitable For

The course is designed for any Level 2 or 3 UT technician who is required to perform data acquisition and analysis or is tasked with procedure and
technique development. The benefit to the employer will be significant, as the graduate of this course will be capable of analyzing, solving and reporting clear comprehensive findings for many NDT/NDE applications.

Duration

5 days (40 hours)
50% classroom, 40% hands-on, 10% testing

Course Equipment and Materials

Extending the tools to include TOFD wedges and probes, along with a range of scanning systems, ensures students get the most from the
course. Combination of PA and TOFD is shown using the ESBeamTool for a range of technique demonstrations. The students are afforded
the opportunity to scan a wide range of flaw sample and have access to numerous calibration blocks.

Requirements for Successful Completion

A mark of 70% is required for successful completion and certification. The final pass mark is based on combined daily quiz marks and final exam. A Certificate of Completion is provided.
