A Stenciling Delay System for Steel Plate Ultrasonic Flaw Detection Process

Abstract

Abstract:In the process of steel plate ultrasonic flaw detection, once the instrumentation discovers the flaw, a sign is stenciled in the vertical direction of the flaw, because there is a distance between the detector and stenciling, an effective method must be applied to reasonably control the stenciling, in order to achieve the precise stenciling. Based on characteristics of the steel plate flaw detection process, the delay distance between each group of detectors and stenciling has been analyzed, simultaneously based on the flaw detection speed, stenciling delay data has obtained. Stenciling delay structure is developed using the computer software technique, instead of hardware control mode, software algorithm is carried out to design, which has achieved the goal of convenience application and precise orientation.
