A Study on the Application of Arc Sensor to FCA W for The Fillet Plates of Shipbuilding

조선용 Fillet 부재에 대한 FCAW용 아크센서의 적용연구

An arc sensor for seam tracking is developed to automate sub-assembly welding in shipbuilding. We utilize a moving average method, which produces an effect of low-pass filter, to generate the position compensation. Therefore the sensor is able to modify the path of the weld seam in real time. By simplifying the compension process, the tunning time is reduced so that operators react quickly. It turns out that this sensor is highly reliable and it is installed and being used in SHI Keoje shipbuilding yard.
