FMR is an NDT metallurgical inspection technique that is used for evaluating plant equipment such as heaters, boilers, piping and reactors.
FMR is a simple process, Using portable equipment, the metal surface is ground and polished to a mirror finish. The polished surface is subsequently etched to reveal the microstructure.
A replica of the etched surface is then made with a thin piece of acetate film. Continua The replica can then be examined back in the field using a portable optical microscope or in the laboratory. This process gives our metallurgical engineers the ability to examine microstructural features such as grain size, cracks, carbides, creep and other damage mechanisms. It can confirm observations made by other non- destructive methods such as acoustic emission tests, penetrant examination and ultrasonic flaw detection and take it a step further to identify the nature of the flaw.
