In the construction of pipelines/ pipework for the transporting of petroleum, gas, chemical, or other fluids/slurries, it is critical to perform nondestructive testing (NDT) of the welds. Why? Comprehensive...
Visual Testing (VT) technicians often need to inspect internal welds, welds that are often deep inside a part or assembly, or are in some way not easily accessible. In...
When it comes time to choose the proper ultrasonic thickness gage for your needs, many factors must be considered. Many of the important points are obvious such as budget...
Ultrasonic nondestructive testing (NDT) is a well-established technique that utilizes high frequency sound waves to locate cracks and other hidden flaws in metals, composites, and plastics. In the metals...
As the use of fiberglass and carbon fiber composites in manufacturing has grown, so has the need for reliable nondestructive testing, both in the initial fabrication stage and while...
A longitudinal beam is also known as a straight beam, or compression wave. Some people think that NDT technicians who are certified as Level II ultrasonic testing (UT) thickness...
Ultrasonic Testing (UT) is a versatile volumetric nondestructive testing (NDT) method that enables the NDT technician to investigate the full thickness of the material being examined. The method is...
