Ensure Non Destructive Testing with Ultrasonic Testing

Ultrasonic testing is acknowledged as one of the preferred methods of non-destructive testing or NDT. The services in ultrasonic testing entail not only the flaw detection thickness and its subsequent mapping using sophisticated data acquisition software but also corrosion affected products. Thus, the machines could be used for physical examination of welds in products like plate, vessels and piping. Latest technology and software make the task of examination, reporting as well as analysis of the defect pattern easy to achieve. The latest machines that are used for different products include Internal Rotating Inspection Systems, Automated Pipe Scanners, Near Drum Scanners, Tank Crawlers and Guided Ultrasonic Wave. All these machines meet the industry’s most rigorous standards in materials testing.

The present day machines used in ultrasonic testing can be applied to almost all the fields. These fields include Aerospace and Power Generation, Nuclear and Petrochemical, Automotive and Pharmaceutical besides Pipeline, Pulp and Paper Industries. Thus, in the field of Aerospace Electro Magnetic Acoustic Transmission or EMAT is used. EMAT essentially produces an ultrasonic wave in the part being tested as opposed to the transducer. By studying the pattern of echoes from the original pulses it is possible to analyze the sample to the extent of assessing the depths of individual cracks that might exist as flaws. You can therefore completely assess the structural integrity of the sample without having to damage it in any way.

Similarly, Time of Flight Diffraction or TOFD, which is an automated and computerized system, can be used for the inspection of welds. The inspection is carried out by the use of probes that are mounted on a buggy traveling along the welded track. The Data Acquisition Software records the dimensions of the cracks accurately unlike older and more conventional methods of ultrasonic testing. Modern tools have made it possible for you to keep your rejects low by identifying the extent of flaws in individual products without causing any damage to them. This is true irrespective of the industry your products lie in. As a result, the economic spin-offs of utilizing such a system can be appreciated.
