Summary: 

This course is for UT technicians who are preparing for a UT Practical exam, or need to refine skills left dormant due to lack of use. Most of the course is spent with a probe in hand, and the class size is strictly limited, due to the amount of direct supervision and feedback offered. Flaw Detection, Identification, and Sizing are the goals here.

Location: Flexible

Course Duration: 40 hours

Maximum number of students: 5
Candidates

Prerequisites: Formal training or certification in at least one of the following:

  • UT Level I
  • UT Level II

Course Fees: $2381 + GST = $2500/person



*Financing options available to qualified candidates. Please contact us for more information*
Manual UT (MUT) Skills Training: Advanced MUT for the detection, characterization and sizing of weld defects KNDT # 007 1

The equipment is provided FOR the student: UT Flaw Detector and Probes

  • 45°, 60°, and 70° wedges
  • Transducers to fit wedges, 2.25 MHz and 5 MHz
  • Cables, etc.
  • Rulers and magnetic rulers
  • Couplant, cleaning rags
  • Scientific Calculator

PPE to be provided by candidate: CSA approved work boots.

Certification: Yes. This course qualifies as 200 hours of field experience toward CGSB Certification in Ultrasonics, Level I or II.

Outline:

  • Codes and Standards
    1. Procedure Review
    2. ASME
    3. CSA W59
  • Calibrations
    1. DAC
    2. TCG/TVG
    3. Sensitivity
    4. Accuracy
  • Mathematics for Manual UT
    1. Near Zone
    2. Trigonometry
    3. Calculate Radius as a Function of Angle
  • Flaw Detection
    1. Lamination or Corrosion?
    2. Geometry or Real?
    3. Sensitivity
    4. Probe Motion
  • Identify the Reflector
    1. Echo Dynamics
    2. Probe Placement and Motion
    3. Materials and Processes
  • Sizing, and Advanced Sizing Techniques
    1. 6dB drop
    2. Avoiding 6dB Drop Complications
    3. Tip Diffraction
    4. Volumetric “Diameter” Calculations
  • Practical Application
    1. Scan for lamination/corrosion reflectors
    2. Scan welds for various defects
    3. Use different Acceptance Criteria
    4. Draw welds and defects for reporting
  • Final Exam
    1. Scan weld with at least 3 defects
    2. Identify defects
    3. Locate and size correctly
    4. Identify defect(s) correctly
    5. Create a drawing for repair reference

Upon completion of the course, technicians will have proven ability to:

  • Set up DAC, TCG/TVG, as required
  • Confidently Detect, Identify and Size various defects in welds
  • Understand the use of Echodynamics as a method of investigating reflectors
  • Understand what the UT Flaw Detector’s screen offers for investigating reflectors
  • Control probe motion in order to more accurately measure reflectors
  • Efficiently investigate if a signal is from corrosion or a laminatio
