초록

본 연구에서는 용접전류 및 용접전압 신호처리에 의한 용접 상태 검출에 있어 용접 와이어의 직경이 미치는 영향에 관하여 연구하였다. 실험을 위하여 인위적으로 모재의 간격을 용접 와이어보다 작은 경우와 큰 경우에 대하여 분석하였다. 사용된 용접 와이어의 직경은 1.2 mm이었으며 인위적으로 형성한 용접 모재 사이의 간격은 1.0 mm와 2.0 mm 두 종류를 사용하였다. 실험결과 용접 와이어의 직경보다 큰 용접 결함 요인에 대하여서는 용접전류 및 용접전압의 변화를 감지할 수 있으나 직경보다 작은 용접 결함 요인에 대하여서는 용접전류 및 용접전압의 변화를 감지할 수 없었다.

Using the welding current and voltage signal processing, we have studied the influence that the diameter of the welding wire to the welding quality detection. For the experiments, We have analyzed the signal with respect to large and small artificially a gap between base materials than the welding wire. In this experiment, the 1.2 mm diameter of the welding wire was used, and distance between the welding base materials was respectively 1.0 mm and 2.0 mm. In the welding with a large defect than the diameter of the welding wire it was able to detect a change in the welding current and welding voltage. But it could not detect a change in the welding current and welding voltage in the welding has a small defect than the welding wire diameter.
