Joint tracking system for butt joint welding process using eddy current sensors with the condition of no gap distance

자기장 센서를 이용한 갭간격이 없는 박판 맞대기 용접부의 용접선 추적 장치

In recent years, much progress has been made in the automation of welding coped with a variety of highly flexible sensors. Among these sensors, only the eddy current sensor can detect the center location of the butt joint whose gap distance is zero. Thus, in this study the eddy current sensor is used to develop a robust and useful joint tracking system. The developed system is tested to qualify the performance of the system and seam tracking algorithm is proposed and two simulation are executed to show the performance of the proposed tracking algorithm.
