Ultrasonic testing device for rail bottom and testing method using the same

Abstract

The invention discloses an ultrasonic testing device for rail bottom and a testing method using the same. Top surfaces of both sides of the rail bottom include at least one working surface respectively, and the working surface is at least provided with one set of phased array probe assemblies. Each set of phased array probe assemblies includes two phased array probes distributed on both sides of a weld seam, and the phased array probe forms a contact area with the working surface and generates pulsed ultrasonic beams with different incident angles to enter the rail bottom for flaw testing. The phased array probe can be deflected relative to the rail bottom to realize full-coverage testing for the rail bottom.
