arc strike

The effects such as welding position, rewelding times, pre-heat and slowly cooling, arc stop/ strike and length, power selection, environment control, sequence, direction, and assembly were analyzed.

分析了焊接位置、补焊层数及两面补焊、预热和缓冷、补焊的收/起弧及长度、电源选择、环境控制、补焊顺序和方向，以及装配等因素的影响。

Study on Arc Back Strike Phenomena in Low Voltage Circuit Breakers

低压断路器电弧背后击穿现象的研究

In industrial environment, due to the motor switch, electrostatic discharge or adjacent arc strike, they often can produce up to hundreds or even thousands of volts.

工业环境中，因电机开关、静电放电或者邻近电弧闪击，常常会产生高达上百甚至上千伏特的冲击电压。

Arc strike marks on base metal outside the weld joint should be avoided but if present should be treated as defects requiring removal or repair.

应防止在焊接接头之外的母材上产生弧击痕迹，但是如果出现了，就应按照焊接缺陷来进行处理，需要清除或补焊。（请指正）
