How many rally cars barrell roll at 330mph or even 200mph? I've worked on pro mod cars and I think having a TIG welded roll cage has saved people.
TIG is stronger and far easyer to control heat and penetration.
I still use the mig for fitting panels and hate being burnt ha ha.
TIG welding is used on such cages because of the materials used in their fabrication. And having a well designed and fabricated cage saved lives. It certainly isnt because they are TIG welded.
How many drag cars impact directly into trees at any speed ? Or how many might fall off a cliff and drop hundreds of feet ? None that I can ever recall.
Drag strips are designed so there is little chance of any direct impacts which would cause severe damage.
A proper weld is a proper weld regardless of method.
And what you you mean by recommendations for a 5kg roll ? Any welding supply shop should have it. 5kg will last you a long time, and stainless isnt overly cheap.
Although it can do no harm having it.
