熔核尺寸和焊接强度,焊接时间和焊接电流在一定范围内可以相互补充。 In order to ensure the nugget size and welding strength of the spot welder , the welding time and welding current can complement each other within a certain range. In order to obtain a solder joint of a certain strength, a large current can be used for a short time (under strong conditions, also known as hard specifications), or a low current can be used for a long time (under weak conditions, also known as soft specifications). The choice of hard or soft size depends on performance, metal thickness and power of the welding machine used. There are upper and lower limits for the current and time required for metals with different properties and thicknesses, whichever is in use. R 有明显影响。 The electrode pressure has a significant effect on the total resistance R between electrodes . R 值显著降低,但焊接电流的增加并不显著,这不会影响 R 值降低引起的热产量降低,因此,焊接接头的强度总是随着焊接压力的增加而降低。 As the electrode pressure increases, the R value decreases significantly, but the increase in welding current is not significant. This does not affect the decrease in heat yield caused by the decrease in R value. Therefore, the strength of the welded joint always decreases with the increase in welding pressure . The solution is to increase the welding current while increasing the welding pressure.
