Surely it should be mandatory for the welder to have at least gained some sort of certificate in welding, (not really a very difficult thing to do) helping to bring down the accident rate from twice what it is for factory built light aircraft?Īlthough learning all about welding from a book etc is also necessary, it is also an art, it can only be perfected by practice and from the aptitude and ability of the person holding the torch or electrode, not an over enthusiastic novice dreaming that he knows all about it (because he read about it) and starting his project anyway!īecause it shouldn't be. Hopefully most of the people asking these questions are not really serious about building and just talking. I haven't been involved in flying an aircraft constructed in this way of course but, as a retired engineer I'm keen to find out what the regulations (if any) regarding this dangerous practice actually say. What happens if someone buys one of these aircraft, trusting the builder that it is safe? This is lunacy, but I did once see a helicopter (which I would never have even considered flying in) which had obviously been constructed by an incompetent welder and it set me thinking, why isn't this practice regulated more?
Welding 4130 standard notes how to#
What worries me a lot is that I notice that many people on this forum ask about how to weld Hi Tensile tube and many of the people asking seem to be learning to weld from scratch on an aircraft project! - how can this be? at least, how can it be possible to be allowed to get an aircraft in the air, having been built by a novice welder?
