Reliability of dynamic resistance spot welding control system of α activate type α触发式动态电阻(DR)点焊控制系统的可靠性
The paper mostly studied the capability of the aerial lead acid storage battery and the relation between the capacity and dynamic resistance. 着重论述了航空铅酸蓄电池容量与蓄电池变化的内阻之间的关系;
Result show that dynamic resistance and electrode displacement signals can reflect welding process. 分析表明,动态电阻(DR)和电极位移信号能够反映熔核的生长过程。
The variation of dynamic resistance is one of the most important factors in resistance spot welding. 动态电阻(DR)变化是电阻点焊过程中的重要内容。
In addition, the dynamic resistance in spot welding and its frequency spectrum are analyzed. The relationship between the dynamic resistance curve without type character and nugget size is founded. 另外还对焊接过程的动态电阻(DR)进行了分析,研究了不具有典型变化特征的动态电阻(DR)曲线与熔核直径的关系,并对动态电阻(DR)曲线进行了频谱分析。
