| 摘 要： | 论述霍尔效应式点焊焊接电流的测量方法。由于焊接电流波形失真比较大，所以选用集成真有效值交直流电压转换器，该转换器抗波形畸变能力强。并且提出了对霍尔元件、放大器和电阻选择的方法。

| Abstract: | The measurement method of the Hall Effect type of the welding current for point welding is elaborated in the paper. Because the waveform distortion of the welding current is larger, root-mean-square type of the AC/DC transformer of integration is used. This transformer is capable of anti-distorting. Also the methods of choosing Hall element, amplifiers and resistors are proposed. |
