- Ultrasonic Testing (UT) uses high frequency sound energy to conduct examinations and make measurements. Ultrasonic inspection can be used for flaw detection/evaluation, dimensional measurements, material characterization, and more. Ultrasonic testing is carried out using an ultrasonic flaw detector and an ultrasonic probe. In the inspection, ultrasound is sent into the area of interest by straight beam or angular beams.
- The ultrasound can be reflected from an interface (ex. Discontinuity) and received by the probe. The reflected ultrasound is displayed on a cathode ray tube screen in the flaw detector and the signal can be analyzed. This method is good for detecting internal discontinuities. Ultrasonic can be done on all type of materials and forms like casting, welding , forging, rolled products and composite.
- The advantages of Ultrasonic Testing is it provides instantaneous result, Equipment can be highly portable or high automated, Nonhazardous, Highly accurate, minimum part preparation is required and low cost.We have a team of qualified and experienced Engineers.

Ultrasonic testing objects and thickness ranges
Ultrasonic testing is appropriate for inspecting raw materials and components of pressure equipment, including butt welds, T-welds, fillet welds, and surfacing layers of pressure equipment. Examples of these materials include plates, composite plates, carbon steel and low alloy steel forgings, pipes, bars, solid stainless steel forgings, etc.
