Mobile System for Non Destructive Testing of Weld Joints via Time of Flight Diffraction (TOFD) Technique
This paper describes research towards the development of a robotic system for automated welded joint testing. The tests are often carried out manually by skilled personnel. Automating the inspection process would reduce errors and associated costs. The system proposed in this paper is based on a mobile robot platform and is designed to carry ultrasonic sensors in order to scan welds for defects. The robot is equipped with a vision system in order to detect the weld position. A fuzzy control system is used in order to control robot motion along the weld.
