Nondestructive Testing (NDT) plays an extremely important role in
quality control, flaw detection and structural health monitoring
covering a wide range of industries. There are varieties of NDT
techniques in use. This course will first cover the fundamental
science behind the commonly used NDT methods to build the basic
understanding on the underlying principles. It will then go on to
cover the process details of each of these NDT methods.
