How to solve the dents after welding with intermediate frequency spot welding machines?

When operating a medium frequency spot welding machine, you may encounter a problem where the solder joints have pits, which directly leads to substandard solder joint quality. So what is the reason for this?

The causes of dents are: excessive assembly clearance, small blunt edges, large volume of molten pool, and liquid metal falling due to its own weight.

Reasons for radial cracks on the surface of solder joints:

1. Insufficient electrode pressure, insufficient forging pressure, or untimely addition.

2. The electrode cooling effect is poor.

Solution:

1. Adjust appropriate welding parameters.

2. Strengthen cooling.
