The quality of resistance spot welding of low carbonsteel and high strength low alloy steel is studied by looking into the dynamic voltage characteristics of the electrodes.
本文通过对电阻点焊电极电压动态特性的分析，研究了低碳钢及低合金高强度钢电阻点焊的质量问题。

Carbonsteel has high and low temperature strength is very tough and has excellent fatigue strength.
碳钢具有高温和低温强度，具有很高的韧度和优异的抗疲劳强度。
