weld time

Reducing welding current and weld time were found to reduce electrode sticking .

电极粘附力随点焊电流和点焊时间的减小而下降。

The electrode sticking mechanism and factors affecting the sticking , including welding current , weld time , electrode force and electrode spacing , were studied during micro resistance welding of thin nickel plated steel to nickel sheet .

研究了镀镍钢板和镍板微型点焊时电极粘附的机理以及焊接电流、焊接时间、电极压力和电极间距对电极粘附力的影响规律。

The plasma arc welding have a high energy density , thick welding thickness that can weld for single time .

等离子弧焊具有能量密度高，一次性可焊厚度大等优点。

Based on the above results , make sure the temperature filed distribution near the keyhole close to that near the satisfactory weld at the occurrence time of the keyhole by controlling the process parameters , the uniform formation of weld in the starting process is finished at last .

在此基础上，通过控制起弧程序，确保穿孔时刻小孔周围的温度场分布接近优良焊缝的温度场分布，最终实现起弧的稳定成形。
