NHRA Welding rules??

the no grind is in reference to trying to pretty up the weld and smoth out the welds for a finished look.
you cand grind the welds all you want to make a reweld for good penetration or a weld that has craters in it from contamination on the material. allways clean the surface to be welded with a flap disc on a angle grinder. all roll bar material has a mill scale on it that needs to be removed. also use something to clean any oil off the metal.

DO NOT I REPEAT DO NOT USE BRAKE CLEAN to clean the meterial to be welded !!!!!!!!

I made the brake clean mistake once and only once!! Was welding, laying on my back no less,
and right away I knew what I did wrong. I thought back to my apprenticeship and how that nasty gas is heavier than air and my instructor said to stand on your head against the wall to help drain that junk from your lungs. I did and it worked! Now I warn everyone about it when I remember. Thanks for posting this.

If you can't weld good, weld a lot.
