NDT 206 - Ultrasonic Testing (UT) Level II

3 Credits, 3 Contact Hours
3 lecture periods 0 lab periods

Prepares the student for flaw detection and angle beam inspections of welds, instrumentation and display formats, AWS and ASME style calibrations, and discontinuity interpretation and evaluation as per ASME Sec V article 4, AWS D1.1. Includes training students to identify waveform characteristics of various material defects, and enables them to develop and apply techniques.

Prerequisite(s): NDT 106
