正常焊接状态时变频控制交流脉冲频率。
Varying frequency is used to control AC pulse frequency in normal welding state.
在这种控制法中电流分为焊接状态稳定化脉冲和焊接脉冲。
Electric current is classified into welding state stabilization impulse and welding impulse in this control method.
利用R BF人工神经网络及SVM模型建立电弧声信号与焊接状态的映射模型，从而实现焊接过程状态的模式识别。
RBF Network and SVM model are used to set up the image model of arc sound signal and welding state in order to realize the pattern recognition on-line of the welding conditions.
