The Working Process of Medium Frequency Spot Welding Machines

Today, let’s discuss the working knowledge of medium frequency spot welding machines. For friends who have just entered this field, you might not fully understand the usage and working process of spot welding machines in mechanical applications. Below, we’ll outline the general working process of medium frequency spot welding machines:

1. Pre-Welding Preparation

Before welding, it’s essential to remove any oxides on the surface of the electrodes and check the lubrication condition of all rotating bearings.

Ensure that the transmission chain is functioning properly, avoiding any instances of jamming or misalignment between the chain and sprockets.

Thoroughly inspect the spot welding machine and associated equipment to ensure the normal operation of its circuits, water circuits, air circuits, and mechanical devices.

1.1. Surface Preparation

Clean the electrode surface thoroughly to remove any oxides that may affect the welding process.

1.2. Equipment Inspection

Check the condition of all components, including bearings and chains, to ensure smooth operation during welding.

2. Welding Process Guidelines

During operation, ensure there are no blockages in the air circuit or water cooling system. The gas should be free of moisture, and the drainage temperature should not exceed 40 degrees Celsius.

Keep the cylinders, piston rods, and bearing hinges of the cylinders smooth and well-lubricated.

Tighten the adjustment nut for the task stroke of the upper electrode. Adjust the electrode pressure according to welding standards by rotating the pressure reducing valve handle.

2.1. Process Monitoring

Regularly monitor the welding process to ensure smooth operation and adherence to quality standards.

2.2. Maintenance Checks

Regularly inspect and maintain the equipment to prevent blockages or malfunctions during welding.

3. Post-Welding Procedures

Ensure there are no blockages in the cooling water system and regularly discharge cooling water.

Before and after use, grind the electrode surface to maintain its effectiveness.

During the welding process, if the task needs to be paused, cut off the power supply, gas supply, initial closed water supply, remove debris and splashes.

3.1. Cooling Process

Ensure proper cooling of the equipment to prevent overheating and maintain operational efficiency.

3.2. Maintenance

Regularly maintain and clean the equipment to prolong its lifespan and ensure optimal performance.

Conclusion

In conclusion, understanding the working process of medium frequency spot welding machines is crucial for efficient and safe operation. By following the outlined steps for pre-welding preparation, welding process guidelines, and post-welding procedures, operators can ensure the longevity and effectiveness of the equipment: leo@agerawelder.com
