What are the preparations before starting the automatic spot welding machine?
Dec 10 , 2021
The electrode pressure of the battery pack automatic spot welding machine has a significant effect on the total resistance R between the two electrodes. As the electrode pressure increases, R decreases significantly, while the increase in welding current is not large, and it cannot affect the decrease in R. Heat production is reduced. Therefore, the strength of the solder joint ...
