NON-DESTRUCTIVE TESTING

BIRCLAR can provide a variety of non-destructive testing to pinpoint hard to see surface and internal cracks and flaws in ferrous and non-ferrous materials such as shafts, rotors, gears, etc.  These tests can provide early detection of flaws and prevent catastrophic, costly failures of installed equipment.

MagnaFlux

MagnaFlux Liquid Penetrant Inspection is a non-destructive test method which provides for the detection of surface cracks in ferrous and nonferrous materials.

Cracks are determined by the use of a liquid penetrant with fluorescent properties. The penetrant migrates into surface openings by capillary action and is then analyzed with the use of a black light.

Sonic or Ultrasonic Testing

Ultrasonic testing detects both linear and non-linear flaws and permits three dimensional interpretation. Any material which transmits mechanical vibrations can be tested. 

The UT instrument converts electrical pulses into mechanical
vibrations or waves. These waves travel across the tested specimen and reflect from flaws because of their different acoustic nature. The returning reflected waves are re-converted to electric energy and displayed as signals on a CRT. The position and size of these signals correspond to the position and size of the flaws.

X-Ray

Material density and its thickness set the limits of X-Ray's usefulness. Internal flaws are X-Ray's forte.  X-Ray uses penetrating radiation and works on the principle that denser or thicker materials will absorb more radiation. 

The specimen is placed between a source of radiation and a sheet of radiographic film or image amplifier. A flaw present anywhere within the specimen will absorb less radiation than the specimen itself. The flaw's presence and location will be indicated by an area of higher or darker exposure.
