I need to tig weld on the end of a 1/4 inch bolt but the bolt must be in the threads of a nut welded to a plate (it's a boss) during the weld. I assume there may be arcing and I might weld my bolt to the nut. Correct?
Can I reduce the possibility of unwanted arcing by grounding on the bolt itself and not the plate?
If "yes" to my most previous question, then does it matter if I ground on the part of the bolt that is past the nut and closest to the weld? Here is an ascii picture:
