That would be good practice, but where is it required in the rules?

See 9.4.G.4:
It is recommended that all joints of the roll cage be welded. All welding must include full penetration, no cold lap, no surface porosity, no crater porosity, no cracks, no whiskers, and so forth. Alloy steel must be normalized after welding. It is recom-mended that a certified AWS D1.1 welder do all welding.
