The operation of resistance brazing is very different from that of resistance spot welding.Resistance brazingIt needs to maintain a high temperature for a certain period of time to melt the solder, while spot welding requires heating to the melting point of the base metal before forging, so the operation is also different.
1. Stack the two ends of the workpiece to be welded together, place it under the carbon electrode and press it tightly. 2. Set a smaller welding current value first, then step on the foot switch to control the heating. If you step on it, it will heat, and if you release it, it will stop heating. 3. Test the heating speed. If it is too slow, increase the current. 4. When the temperature is lower than the melting point of the workpiece and higher than the melting point of the solder, hold the solder evenly to fill the gap between the two workpieces. 5. After brazing, put it into cold water to allow it to crystallize quickly.
