ABSTRACT:
A rail section weld inspection device [1000] is described for inspecting a rail [10] for internal defects [19,21]. A central ultrasonic (US) probe [1330] transmits at least one US beam [B] through the rail [10] and receiving a reflected signal. At least one angled US probe [1310] transmits at least one US beam [A1-A5] through the rail [10] at an oblique angle at least partially covering the same region as the central probe [1330]. An encoder identifies the location of the US probes [1330] and [1310] along the rail [10] and pairs the locations of the probes with the signals received. The Calculation device [1500] receives the signals from the US probes and uses their different views to create an image of the flaws within the rail [10].
