当过热或者高电流或电压脉冲导致触点焊接在一起时,就会发生接触故障,形成短路。
Contact failure can occur when excessive heat or a high current or voltage pulse causes the contacts to weld together, resulting in short circuits.
并针对DP590GA焊点熔核中锌元素的残留现象,设计出加预热的双脉冲焊接规范,进一步改善其点焊接头的力学性能。
Aiming at the zinc residue in the weld joint nugget of DP590GA, a double-impulse welding parameter with preheating impulse is designed to further improve its mechanical properties of the weld joint.
