TOFD equipment

The system is designed for testing long welded joints of pipes, tanks, vessels, cisterns, ship hulls, bridges, etc. using TOFD technique. Circumferential welds with a diameter from 12 in (300 mm) can be inspected on cylindrical objects. On cylindrical, spherical, as well as complex shaped objects with a radius of surface curvature from 16 ft (5 m) to flatness, the system is capable of testing long welds in any direction. Objects with wall thickness from .25 to 12 in (from 6 to 300 mm) can be examined with the help of appropriate probes. Depending on the inspection task, TOFD MAN TM system can be complete with another scanner (see “Scanners”). The amount of probe pairs can vary from 1 to 4. For good coupling, it is advised to use an external coupling liquid supply system. In this case, a water hose will come to the scanner. But if absolute mobility is needed, coupling media can be applied to the object before testing, or a test object can be continuously showered with water

Configuration of the system is maximally optimized for placement on the operator’s jacket, which does not impede the movement, also when performing an inspection at height (climbing, rope access). Standard delivery set of the system features an 8- hour battery to be put in the jacket. The scanner is light-weighted and easy to guide. It ensures handy probes setup.

In the course of and testing, all setup data are transferred to a remote PC (laptop or tablet) via Wi-Fi. A system for protecting the integrity of test data is provided, while they are fully stored inside the TOFD module and transferred to PC at the end of testing. If required, it is possible to use a wire connection to transmit data to PC.
