Magnetic particle and liquid penetrant inspection are the most widely used processes for nondestructive testing. This course provides the student with training in theory and hands-on laboratory projects. You will spend time in the classroom and time in the laboratory. The course will conclude with a written exam.

Successful completion of this exam will prepare the student for Level II SNT-TC-IA and AWS® D17.1 in Liquid Penetrant and Magnetic Particle Testing. Note: Students may bring their own materials for test samples. This course has at least five hours of assigned homework.
