I have an old trailer and one of the wheel hub studs has come loose. After removing the hub and welding the stud I could removed the nut and therefore the wheel.
My problem is that I cannot replace the the stud with a new one as the metal is shot around where the stud would fix. I see the other studs have also been welded into place.
However my welding doesn't seem to be able to penetrate the hub metal. I have a 150amp mig welder turned up full but aren't getting good (virtually no) penetration into the hub. I managed to remove the stud by simply welding it so it would not turn against the side of the hub.
Do I just need to take it to someone with a more powerful welder?
