Solution for Pit Formation in Medium Frequency Spot Welding Machine

During the operation of a medium frequency spot welding machine, you may encounter a problem where pits appear in the welds. This issue directly results in poor weld quality. So, what causes this problem? Typically, when faced with this situation, the weld needs to be redone. How can we prevent this problem from occurring?

Causes of Pit Formation:

Excessive assembly clearance, small blunt edges, resulting in a large volume of molten pool, and the liquid metal falls due to its weight.

Solution:

Adjust the appropriate welding parameters.

Reasons for Radial Cracks on the Weld Surface:

Insufficient electrode pressure, insufficient forging pressure, or untimely application of pressure.

Poor cooling effect of the electrode.

Solution:

Adjust the appropriate welding parameters.

Enhance cooling.
