This document outlines 5 non-destructive testing methods: 1) Radiography testing uses x-rays or gamma rays to detect internal flaws, 2) Magnetic particle and penetrant testing use magnetic fields or dye to detect surface flaws, 3) Ultrasonic testing uses high frequency sound waves to detect internal flaws, 4) Eddy current testing uses electromagnetic induction to detect surface and shallow subsurface flaws, and 5) Phased array is an advanced ultrasonic technique.
