140 - Sonatest VEO Phased Array & TOFD

The Sonatest VEO Phased Array and TOFD course reveals the balance achieved as both methods are demonstrated to comple- ment each other. Practical exercises access a selection of engi- neered 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 implementa- tion. 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.

Objectives

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:
- 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 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 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 demonstra- tions. 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.
