Ultrasonic testing is a key part of corrosion assessment surveys. One example of this type of inspection is Thickness Gauging **, which is a non-destructive investigation of a material’s thickness using ultrasonic waves.
The ability to gauge thickness measurement without requiring access to both sides of the test piece offers this technology a multitude of applications such as paint, plastics, glass, ceramics, metal and other materials.
Portable hand held sets allow for use by our Rope Access Technicians in confined spaces as well, allowing its use in complicated and hard to access areas (Shafts or pipes, wharfs, internal wall sections etc…).
The advantages of Ultrasonics are:
− High penetrating power, which allows the detection of flaws deep in the part.
− High sensitivity, permitting the detection of extremely small flaws.
− Only one surface need be accessible.
− Greater accuracy than other nondestructive methods in determining the depth of internal flaws and the thickness of parts with parallel surfaces.
− Some capability of estimating the size, orientation, shape and nature of defects.
− Non-hazardous to operations or to nearby personnel and has no effect on equipment and materials in the vicinity.
− Capable of portable or highly automated operation.
