As simple as using some tape with a few holes poked in to 'purge air out and get your gas mixture in'  |
This technique is critical for Stainless Steel exhaust. Not so much for mild steel. I've seen some pretty extreme "sugaring" on stainless welds. Not an easy thing to grind, and never as strong as doing it right.
