The steel grating pressure welding machine is a large-scale resistance welding equipment. The welding process is the conversion process of electric energy, which is converted into heat energy. The electric heat is proportional to the current through the conductor, the resistance of the conductor and the time for the current to pass through the conductor. Therefore, it is necessary to master the reasonable application of current, resistance and time in welding. Different parameters need to be set for different types of flat steel and twisted steel. Different current, pressure, and time should be set according to different types of flat steel and twist steel, and the current parameters should be set according to the actual situation.
Problems that are prone to occur when welding
1. The twist steel cannot be pressed down during welding.
2. The twist steel is overmelted during welding.
3. The twist steel turns black during welding, and the welding strength is low.
4. The twist steel and flat steel are suddenly overmelted during welding.
5. There is a short-term power failure during welding.
6. The single twist steel is overmelted during welding.
7. The last pulse signal is lost during welding (the twist steel is dark at the end).
