1. When welding the nut, the nut moves against the original direction.
In this case, you can make tooling, for example: first screw the small rod into the inner hole of the nut, weld the small rod to the flat plate, and then put the nut on the small rod for welding. If it is a positioning tooling, it still cannot To deal with the problem of the nut being out of position, screws can be used to tighten or compress the opposite objects together.
2. The flange welding nut has desoldering and false welding.
The appearance of desoldering and false welding is not easy to detect, and there are many uncertainties. The welding point of the flange welding nut is high and low, and the spot welding machine adjusts the fixing current and fixing time. When the solder joint is too low, it will only cause a weak solder. The output of other spot welding machines and the stability of the power supply will also cause miswelding, which requires the quality and stability of the nut factory to ensure that the welding points are highly consistent; the output power of the spot welding machine must be stable, and if necessary, please add stability to the power supply end.
