Tig welding is not considered structural (iirc), so I would imagine they would require stick, or mig if anything. But either way, I don’t think they care about the certs of the welder (again, iirc), just that it passes the requirements in build quality. The inspector is the one who should be final judge of the welds anyway, it’s their job. Nothing wrong with Tig welding it but depending on the sanctioning body you are required to have all the welds gone over every so often (2ys tops I believe) same thing is required if you use chromely instead of DOM or ERW. You have to have all the welds gone over every so often to ensure the cages structural integrity. One reason why Bolt In cages are better… (Thou people seem to think their not safe) but its better to relay on Grade 10 hardware vs some misc dudes welding abilities… Just doesnt count in NHRA if you run 9s. --- _[View the full topic](https://forums.speedlife.net/t/cage-build-time/115332)._
