在车身制造中被大量应用的电阻点焊，现在在修理中也逐步开始应用了。
In automobile body manufacturing is a large number of applications of resistance spot welding, now also gradually began to apply in the repair.
随着汽车材料的发展，有些超高强度钢不能采用气体保护焊焊接。气体保护焊焊接的热量会破坏超高强度钢的内部结构，使其强度降低。所以只能采用电阻点焊来修理。
With the development of automotive materials, some of the ultra-high strength steel gas shielded welding welding will not be used. Gas shielded welding welding heat will damage the internal structure of ultra-high strength steel, reduce its strength. So can only use the resistance spot welding to repair it.
电阻点焊还有一个最大的优点是受操作者的影响比较小，只要调整好焊接压力、焊接电流和焊接时间后，每个焊点的焊接质量基本不会发生大的偏差，焊接质量比较稳定。螺柱焊机
Resistance spot welding and one of the biggest advantage is less affected by the operator, as long as adjust welding pressure, welding current and welding time, each solder welding quality of basic won't happen big deviation, welding quality is stable.
在电阻点焊的修理作业中，应该注意焊接质量的控制。一般的电阻点焊机的焊接电流能够达到6000A左右，对于车身上一般的板件都可以进行焊接。
In the resistance spot welding repair work, should pay attention to the welding quality control. The average resistance spot welder welding current can reach 6000 a, for general car body panel welding can be performed.
但是对于一些超高强度钢，焊接电流可能要达到9000A以上，否则焊点不能保证足够的强度。因为从外观看不出来板件是否焊好，在做电阻点焊之前，要找相同的材料进行试焊。
But for some of the ultra-high strength steel, welding current is likely to reach more than 9000 a, or the strength of the solder joint does not guarantee enough. Because not to come out whether panel welding good when viewed from the outside, before making a resistance spot welding, try to find the same material for welding.
在试焊时要不断调整焊接的压力、电流和时间三个参数，然后进行破坏性试验来验证是否达到焊接强度。
When test weld to constantly adjust the welding pressure, current and time three parameters, and then conduct destructive test to verify whether the welding strength.
