Is it important to grind the electrodes of medium frequency spot welding machines?

When the medium frequency spot welding machine is working, due to long-term welding, countless impacts of instantaneous high current and countless collisions of hundreds of kilograms of pressure, the electrode end surface changes greatly, which will cause poor welding consistency.

During welding, the contact resistance and the internal resistance of the plate itself generate heat to form a weld nugget under the action of a large instantaneous current, and a solder joint is formed under the later action of the electrode. This requires a high electrode current density of several hundred per square millimeter at the solder joint. Ampere or so, if the welding end face is too damaged, it will cause distortion of the welding parameters. Due to the customer’s lack of understanding, many customers do not often polish the electrode when using it. Even extreme customers have never polished the machine after buying it, and then it will continue to Increasing the welding time and welding current results in thicker solder joints, larger heat-affected zones, and poor appearance of the solder joints.

Therefore, during normal welding, try to grind the electrode as often as possible to ensure the consistency of the solder joints. Using the electrode grinder of the intermediate frequency spot welding machine can basically ensure the consistency of the welding spots. Common electrode grinders are not manual types. The production line is generally equipped with a pneumatic or electric grinder, which greatly improves the welding quality and production efficiency.
