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