A method for inspecting the application of a weld overlay to a pipe using a robot

By using a robot to inspect the coating on pipe welds and generating a weld thickness cloud map through scanning with multiple components, the problem of low inspection accuracy in existing technologies has been solved. This enables full inspection and supplementary coating, thereby improving inspection accuracy and efficiency.

Abstract

The application discloses a kind of detection methods for pipe weld coating using robot, it is related to pipe robot technical field, to solve the low accuracy of the inside pipe weld thickness sampling inspection, cannot accurately reflect the problem of overall weld coating effect.The method comprises the following steps: S0, system initialization and environment self-adapting calibration;S1, binocular camera assembly scanning obtains target pipe number, locates target pipe position;S2, coating robot scans target weld of target pipe during traveling, obtains original point cloud dataset M of target weld;S3, after spraying operation is completed, if coating robot scans target pipe number again, then the target weld is scanned again by combining IMU attitude and pipe number feature point matching, and obtains post-spraying point cloud dataset N of target weld;S4, according to original point cloud dataset M, post-spraying point cloud dataset N is processed and calculated, and weld thickness cloud chart is obtained.
