What problems will occur during the use of welding nuts?

1. When welding the nut, the nut moves against the original direction.
In this case, tooling can be made. For example, first screw the small rod into the inner hole of the nut, weld the small rod to the flat plate, and then weld the nut on the small rod. If the positioning tooling is still unable to handle the problem that the nut violates the original position, screw it down or press it to fix the relative objects together.
2. The welding nut has desoldering and false welding.
The appearance of desoldering and false welding is not easy to find, and there are many uncertain factors. The welding point height of the welding nut is adjusted by the spot welder to adjust the fixed current and fixed time. When the solder joint is too low, it will only cause faulty soldering. The stability of the output and power supply of other spot welding machines can also cause faulty welding, which requires the quality and stability of the nut factory to ensure the consistency of the height of the welding points; The output power of the spot welding machine should be stable. If necessary, add a voltage stabilizer at the power supply end.
It is worth noting that the welding method for welding nuts is resistance welding. The use of electrode or carbon dioxide maintenance welding in resistance welding is not as good as projection welding. The use of general welding rods can be completely replaced by carbon dioxide maintenance welding, which has high efficiency, low cost and good quality.
The welding nut parameters depend on the fusion size of the weld. The welding parameters are adjusted according to the fusion size until the defects are eliminated. Of course, the welding quality is related to the pre-welding treatment and whether there are impurities and oil stains on the welding surface. Due to the high temperature, the connector can not be disassembled due to deformation, and some shiny metal can not be welded by common methods, such as aluminum, magnesium, etc., which requires gas welding or argon arc welding, and the processing process and precision requirements are high.
