Device for detection of defects in welded rail joints

A device for detection of defects in welded rail joints, the device comprising:

• a display configured to provide an operator with operating mode options;
• two scanners, each with an ultrasound phase-array transducer;
• an emission controller for the ultrasound phase-array transducers;
• the scanners configured to provide inspection of the welded rail joints using
• (i) the two ultrasound phase-array transducers directed at each other, operating separately and generating a beam sector of 36 to 75 degrees;
• (ii) the two ultrasound phase-array transducers directed towards each other and operating separately, wherein the transducers generate a beam sector of 26 to 24 degrees from a tread surface during longitudinal movement along a rail;
• and/or
• (iii) the two ultrasound phase-array transducers directed towards each other, wherein one of the two transducers emits a transverse wave from the tread surface to a base of the rail, while the second transducer receives a longitudinal wave that occurs only when a vertical defect exists in the rail,
• wherein the scanners are configured to perform (i), (ii) and/or (iii) singly or sequentially, in any order, based on selection by the operator, and
• wherein the defects are shown on the display after the inspection.
