Time of flight diffraction ultrasonic testing is excellent for detecting weld discontinuities and defects. To do this, at least two ultrasound probes are moved along the axis of weldment. One probe is known as the transmitter, which sends ultrasonic waves along the top of the weld joint and the backside of the weld joint. The

Phased Array Ultrasonic Testing (PAUT) is an advanced non-destructive examination technique that utilizes a set of ultrasonic testing (UT) probes made up of numerous small elements, each of which is pulsed/phased individually with computer-calculated timing. This technique can be used to inspect more complex geometries that are difficult and much slower to inspect with single

Buried utilities represent a major challenge to electricians who need to trace and trouble shoot such systems. They also represent a hazard to excavation crews. Improperly performed digging can cause cable or pipe damage resulting in personal injury, costly repairs and penalties. Using superior design and powerful software, NNDT offers several new performance features, establishing

Vacuum box testing is a non-destructive examination used when trying to locate weld seam leaks. A vacuum box and a compressor create a high or low pressure vacuum while a detergent solution is applied to the test area. The detergent bubbles, making leaks visible within the created pressure envelope.
