TOFD Inspection Method

TOFD Inspection is a highly reliable nondestructive testing method primarily used for finding flaws in welds. Ultrasonic sensors are placed on either side of weld. One sensor sends the ultrasonic beam in the type of longitudinal wave into the weld and the other receives it. When it counters an anomaly diffracted energy is cast in every direction.

The flaw is detected accurately by measuring the time of flight of   diffracted beams. TOFD Inspection gives helps in determining correct crevice sizes of defects.

 TOFD Inspection can be used on its own or with other ND testing methods. The direct and most popular application of TOFD Inspection is in pipeline welding. TOFD is a massively popular testing method tool since it is guaranteed to give you precise and reliable results all the time.

TOFD Inspection method has profound applications in oil refining, petroleum industries, offshore and marine industries.
