103 - Phased Array & TOFD Applications

The Phased Array and TOFD Applications course reveals the balance achieved as both methods are demonstrated to compliment each other. Practical exercises access a selection of engineered and actual flaw samples.  The TOFD capabilities of the OmniScan 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 OmniScan 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

Level 2 or 3 UT operators with analysis requirements demanding advanced knowledge of phased array and TOFD techniques.  This course is designed to provide the skills required by the technician to calibrate, acquire, and interpret a variety of typical phased array and TOFD data.  The advantages to the employer are immediate and significant, as the graduate technician will be empowered to acquire and analyze UT phased array and TOFD data using the OmniScan instrument and the requisite accessories. 

Duration

5 days (40 hours)
35% classroom, 60% hands-on, 5% testing

Course Equipment and Materials

The course instruments include the OmniScan MX 16/128 and the 32/128 as primary with additional instrumentation available, such as the OmniScan MX2 and the Focus LT. The inclusion of an extensive range of TOFD wedge angles and wide frequency and diameter options for the TOFD component of the course means students can select and see performance and limitations of the application solution they have worked towards. ESBeamTool is provided to enable technique development. Combinations of the phased array and TOFD techniques are presented with ample probe and wedge configurations. Samples for acquisition and sample data files for further analysis experience complete the equipment selection.

Requirements for Successful Completion

A mark of 80% is required for successful completion and certification. Final pass mark is based on combined daily quiz marks and final exam. A Certificate of Completion is provided.
