NDT3468 EDDY CURRENT TESTING II COURSE PROCEDURE


NDT3468 EDDY CURRENT TESTING II

3 Credit Hours

Student Level:

This course is open to students on the college level in either the Freshman or Sophomore year and to area high school vocational students.

Catalog Description:

NDT3468 - Eddy Current Testing II (3 hrs.)

This course is a continuation of Eddy Current Testing I, with emphasis on advanced theory and practical skills required in the application of Eddy Current evaluation methods. The course is designed to meet certain NDT Level II requirements in accordance with A.S.N.T. SNT-TC-1A & NAS-410.

Course Classification:

Lab

Prerequisites:

NDT3467 Eddy Current Testing I or instructor approval.

Controlling Purpose:

This course is designed to impart advanced knowledge and practical skills required for Eddy Current Testing and its applications techniques.

Learner Outcomes:

Upon completion of this course the student will be able to:

  1. Describe the generation and function of eddy currents.
  2. List and describe the differences in eddy current probe design and function.
  3. Choose the correct probe frequency and size for a given test item.
  4. List and describe the variables that effect eddy current inspection.
  5. Perform a multi-frequency eddy current inspection, and correctly interpret the results.
  6. Pass a qualification examination (theory & practice) prepared in accordance with industry standards (SNT-TC 1A & NAS-410).
  7. Correctly apply all safety attitudes and procedures associated with Eddy Current testing that will insure a safe work place environment.
  8. Apply knowledge of Eddy Current inspection to inspect and report materials comparable to that of a Level II Inspector.

Unit Outcomes for Criterion Based Evaluation:

The following outline defines the minimum core content not including the final examination period. Instructors may add other material as time allows.

Attendance Policy:

Students should adhere to the attendance policy outlined by the instructor in the course syllabus.

Grading Policy:

The grading policy will be outlined by the instructor in the course syllabus.

Maximum class size:

Based on classroom occupancy.

Course Time Frame:

The U.S. Department of Education, Higher Learning Commission and the Kansas Board of Regents define credit hour and have specific regulations that the college must follow when developing, teaching and assessing the educational aspects of the college.  A credit hour is an amount of work represented in intended learning outcomes and verified by evidence of student achievement that is an institutionally-established equivalency that reasonably approximates not less than one hour of classroom or direct faculty instruction and a minimum of two hours of out-of-class student work for approximately fifteen weeks for one semester hour of credit or an equivalent amount of work over a different amount of time.  The number of semester hours of credit allowed for each distance education or blended hybrid courses shall be assigned by the college based on the amount of time needed to achieve the same course outcomes in a purely face-to-face format.
