在分析国内外电弧传感的信号处理的发展情况的基础上,针对摆动电弧弧焊作业的实际要求确定了所需要的信号处理方案,由于均值滤波能有效地消除随机噪声,且对消除短路脉冲电流具有影响独特效果,因此综合运用这两种方法对焊接电流信号进行处理,再用积分差值法对其进行偏差提取.最后在Matlab中进行了初步实验,验证了方案的合理性和可行性. Based on the analysis of the development of signal processing in arc sensing at home and abroad, the signal processing scheme is determined according to the actual requirements of the swing arc arc welding. Since the average filter can effectively eliminate the random noise and eliminate the short circuit pulse The current has a unique effect, so the two methods are used to process the welding current signal, then the integral difference method is used to extract the deviation.Finally, a preliminary experiment is carried out in Matlab to verify the rationality and feasibility of the scheme .
