Visual methods can provide a simple and speedy way to assess questionable components and these methods can help in deciding what inspection to do next.
This testing method covers procedures for detecting or locating leaks, where quantitative measurement is not practical.
Ultrasonic inspection uses short wavelength sound waves with high frequency to detect flaws or measure material thickness.
Liquid penetration inspection is a method that is used to reveal surface breaking flaws by bleed out of a colored or fluorescent dye from the flaw.
This method is suitable for detection of surface and near surface discontinuities in ferromagnetic material, mainly ferritic steels and iron.
