During resistance spot welding, direct extraction of Controlling factors for the establishment of good quality and stable nuggets was examined.High pressure generation and its metallurgical effect that was a great segregation of solute elements were shown by direct method.Using this pressure change through electrodes, a computer controlled resistance spot welding machine with feed back system was developed for this research.Experimental results obtained by the thin plate metal specimen (AI, Fe, Brass, Sus) indicated that the Controlling factors for monitoring and feeding back to computer were not only a pressure change but also a micro dilation.Furthermore, it will be necessary to measure and to control this micro dilatation precisely.

在电阻点焊过程中，检查了直接提取建立良好质量和稳定熔核的控制因素。通过直接方法显示了高压的产生及其冶金效应，即溶质元素的极大偏析。利用通过电极的压力变化，开发了具有反馈系统的计算机控制电阻点焊机。通过薄板金属样品（AI，Fe，黄铜， Sus)指出，监测和反馈计算机的控制因素不仅是压力变化，而且是微膨胀。此外，有必要精确测量和控制这种微膨胀。
