Quick Release - Welding

CAMS regs state that any mods to the steering must be signed off by an engineer.
If I am welding a quick release hub/system to the steering column, are there places (Adelaide) that can weld and certify at the same time???
Think I recall a thread somewhere where Roger welded his on but I dont fancy my welding skills on something that important!!!!
