      在常规电阻焊工艺参数调整时有三个基本要素:焊接时间、焊接电流、焊接压力缺一不可,而在储能焊机则无焊接时间调整这一项,焊接电流也是通过充电电压反映出来的,因此储能焊机规范调整主要是在焊接压力和充电电压之间匹配,特殊情况下会再加一项回火电压用于细化晶粒. Energy storage welding machine has three basic elements when adjusting conventional resistance welding process parameters: welding time, welding current, and welding pressure are all indispensable. In energy storage welding machine, there is no welding time adjustment. The welding current is also through the charging voltage. Reflected, so the energy storage welding machine specification adjustment is mainly to match between welding pressure and charging voltage. In special cases, an additional tempering voltage will be added to refine the grain.

工艺调整时需要克服的难点: Difficulties to be overcome when adjusting the projection welding process of the energy storage welder :

1. The welding pressure is set. Because the strength of the hot-formed steel sheet is higher, a larger pressure is required during welding, but the strength of the projection welding nut is lower. The larger pressure will cause the bumps to collapse prematurely, so the welding The pressure is best to use a saddle-shaped pressure curve. The practical situation is that the stepped two-stage pressure is more common. This can ensure that the bumps are not crushed and deformed early, and that there are not too many spatters in the later stage of nugget growth.

2. The setting of charging voltage. Too high charging voltage generates excessive heat during welding. The nut metal appears to be extruded and splashed, which will cause two situations. One is that the spatter will reduce the fusion connection area (overheating). The nut push-off force is reduced, and the second is that the screw plug gauge cannot pass; a lower charging voltage will cause insufficient welding depth, and the nut push-off force will not meet the standard and the welding will be false;

工艺规范调整方法,两个焊接要素(充电电压和焊接压力)调整时需以其中一个为基础对另一数值做出调整匹配,不可同时调做出两项调整;此处应考虑到经验的运用,有类似的螺母凸焊的参数可以做为参考,能有效减少调整的次数,只是热成形板材的焊接需要更大的电流和压力,可以从同规格在普通材料上的测试数据做为起点开始调整,经过试焊及试验室验证找出最佳的数值;需要注意的时,在批量生产时应在试焊数据基础上加大3-5%,以满足产品其它原因造成的波动下限。 The adjustment method of the energy storage welding machine process specification. When adjusting the two welding elements (charging voltage and welding pressure), one of them must be adjusted to match the other value, and two adjustments cannot be adjusted at the same time; here we should consider In the application of experience, there are similar parameters for nut projection welding, which can effectively reduce the number of adjustments, but the welding of thermoformed plates requires greater current and pressure, which can be obtained from test data of the same specifications on ordinary materials. Start adjusting as a starting point, and find out the best value after test welding and laboratory verification. When it is necessary to pay attention, it should be increased by 3-5% based on the test welding data during mass production to meet other causes of the product. Lower fluctuation limit.
