INTRODUCING AUTOMATIC ULTRASONIC INSPECTION TECHNOLOGY TO WELDED RAILS ON A FLEXIBLE FLOATING RAILWAY BRIDGE

A floating bridge was developed mainly for the use of motor vehicles. In recent years, studies on the application of such bridge types for railway vehicles are being carried out. Railways respond sensitively to flexible structures, such as floating bridges, and the welded joints of rails are vulnerable to continuous deformation. The focus of this study is regarding the automatic ultrasonic detection device for rails. More specifically, this device moves between rails automatically and inspects cracks in the welded joints connecting adjacent rails. When the device is not inspecting the welded joints it remains parked between rails. This study intends to introduce the design drawing, management and operation methods of the automatic ultrasonic detection and test device for rails. This technology can be applicable to inaccessible areas efficiently.
