We have achieved a pretty good results with welding them together,but there is a poor penetration into the flat materials. The testing strength is OK. Acc.to the standard the nut is welded with materials with max 0.15%C. We are using the materials with 0.16%C and higher max 0.18%C. Could be problem with %C due to?

Has anyone some experiences with it?

Any material with higher carbon is difficult to weld. I think your problem is mostly due to the higher carbon percentage. For welding, you will have to reduce the weld time and increase the energy. Give a heavy pulse in short time.
