I've heard that the tech inspectors pay specific attention to this. I looked for this requirement in the 2009 GCR, but could not find it in the rollcage section that I thought pertains to IT cars.
IT cars follow section 9.4 Roll Cages for GT and Production Based Cars, and not section 9.4.5 Roll Cages for Formula Cars and Sports Racers, right? Under section 9.4 I can't find this requirement. But under section 9.4.5 I find the following:
9.4.5.E.6.
The reason I was looking is because as everyone is well aware, it is extremely difficult to weld all the way around certain joints, and I wanted to know if there was an allowance where gussets might preclude full circumferential welding. So where exactly is this requirement that sometimes catches some people?...Welds shall be continuous around the entire tubular structure.
