- 論文の詳細を見る
The detection sensitivity of an arc sensor is influenced by the wave frequency of a wire. To explain this phenomenon and to understand the characteristics of an arc sensor from theory and experiment, a simultaneous differential equation used to unstable welding state can be deduced from theoretical and experimental equations, the welding parameters (arc length, wire extension) are calculated by using this simultaneous differential equation, the results can be checked through experiment. The conclusion is that the signal is detected easily under high frequency than low frequency, because the current difference to side of groove under high frequency is bigger than low frequency.
