During our projection welding of nuts on zinc coated surface we often have a problem. Nut supposed to be welded in three points, but often happened that nut is correctly welded only on two points , sometimes just on one, and rarely poor welded at all. After welding, part with nut is going on painting, and when part destroyed for analyses, because of paint rest, we can clearly see what?s happened.
When this happened, our client have problem during assembling, because coaxiality is being lost, and screw cannot pass.
It will be great if any of you have any suggestion how to solve this problem. Thanks
