Information

  1. Adjust the position of the electrode rod first when welding, so that the electrode arms remain parallel to each other when the electrode is just pressed onto the weldment.

 

  2. The number of current adjustment switch stages can be selected according to the thickness and material of the weldment. After power on, the power indicator should be on, and the electrode pressure can be obtained by adjusting the spring pressure nut and changing its compression degree.

  3. After finishing the above adjustment, you can turn on the cooling water first and then turn on the power to prepare for welding. The procedure of the welding process: the weldment is placed between the two electrodes, the foot pedal is stepped on, and the upper electrode is in contact with the weldment and pressurized. When the foot pedal is continued to be pressed, the power contact switch is turned on, and the transformer starts to work. The circuit is energized to heat the weldment. When the foot pedal is released after welding for a certain period of time, the electrode rises, and the power is cut off by the tension of the spring and then restored to its original state. The single-point welding process ends.

 

  4. Weldment preparation and assembly: All dirt, oil stains, oxide scale and rust must be removed before welding of steel weldments. For hot-rolled steel, it is best to pickling, sandblasting or using a grinding wheel to remove the oxide scale. Although the uncleaned weldment can be spot welded, it severely reduces the service life of the electrode, and at the same time reduces the production efficiency and quality of spot welding. For low- and medium-carbon steel with thin coatings, it can be welded directly.

The influence of the pressure of the intermediate frequency spot welder on the welding quality
In the actual intermediate frequency spot welding machine, adjusting the electrode pressure is one of the key parameters of spot welding. The nature of the workpiece adjusts the parameters and pressure. Excessive or too small electrode pressure will reduce the load-bearing capacity and dispersion of the solder joints, especially for tensile loads.

Introduction to the workflow of automatic battery spot welding machine
One is to adjust the effective value of the welding current to make the heat of the internal power source change significantly; second, due to the concentration and contraction of the contact points of the two weldments during the operation of the automatic spot welding machine, concentrated heating occurs there , And the plastic junction area first seems to form unevenly during spot welding plus this unfavorable factor
