How to Address Welding Shunt in Medium Frequency Spot Welding Machines？

Welding shunt, also known as welding diversion or welding offset, refers to the situation where the welding current is unevenly distributed during the welding process, resulting in uneven welding quality and potentially compromising the strength of the weld. In this article, we will discuss how to address welding shunt in medium frequency spot welding machines.

Check the Electrode System: The electrode system, including the electrodes, electrode holders, and electrode cables, should be inspected for any damage or wear that could affect the welding current distribution. Proper maintenance and replacement of worn or damaged parts can help address welding shunt.

Check the Workpiece Alignment: Proper alignment of the workpieces being welded is critical to ensuring even distribution of the welding current. Any misalignment can lead to welding shunt. Therefore, it is essential to ensure that the workpieces are properly aligned and held securely in place during the welding process.

Adjust the Welding Parameters: Welding parameters, such as welding current, welding time, and electrode force, can be adjusted to address welding shunt. For example, reducing the welding current or increasing the electrode force can help even out the distribution of the welding current.

Check the Cooling System: The cooling system, which is responsible for keeping the welding electrodes and workpieces at a consistent temperature during the welding process, should be inspected for any malfunction or blockage that could affect the welding current distribution.

Use Welding Aids: Welding aids, such as shunt bars or shunt plates, can be used to help distribute the welding current evenly across the workpieces. These aids should be properly installed and adjusted to ensure proper current distribution.

In conclusion, addressing welding shunt in medium frequency spot welding machines requires checking the electrode system and workpiece alignment, adjusting welding parameters, checking the cooling system, and using welding aids. By following these steps, welding shunt can be effectively addressed, resulting in high-quality welds and increased efficiency in the welding process.
