    At the very least, you should be required to complete a set of similar type weld tests in front of a certified independent QA specialist. The test samples would be inspected visually first and if that is successful, then they get radiographed. With the criteria established that NO DEFECTS are allowed, the x-ray evidence will certainly weed out the poor and mediocre welders. The home builder should not be allowed to weld anything on an aircraft until he successfully completes the practical demonstration of his skills. When the successful candidate completes his aircraft welding, a certified weld inspector has to inspect and sign off on the air frame - before the home builder encloses it.

    The above outlined solution, when compared to what is being done now - I believe aircraft crashes due to faulty welding should be an extremely rare occurrence.
    Wait, are you sure you're on the right set of forums?

    What you're suggesting is only certified welders be allowed to work on homebuilts, and that their work to be x-rayed and then signed off by an FAA inspector at every step.

    At that point where is the amateur in amateur builder? One of the twin pillars of why Experimental Aircraft are encouraged by the government in the first place is Education. The second is recreation.

    You're advocating something other than that, where only experts should be allowed to build and pilot their own aircraft, something that will not be looked on favorably by the EAA.
    The opinions and statements of this poster are largely based on facts and portray a possible version of the actual events.

    NO I am not suggesting ONLY certified welders be allowed to weld on homebuilt aircraft.
    I am suggesting that anyone who wants to weld parts together on a homebuilt aircraft should be required to demonstrate their skill in front of any journeyman welder in the USA, by welding three sample welds similar to what is required for their aircraft.
    Then the weld sample should be inspected visually by any journeyman welder and x-rayed at your nearest NDT shop. If there are no defects then the homebuilder is approved by the EAA to start welding his aircraft.

    This simple demonstration would probably weed out most of the trainee welders in a hurry. It would reduce failures due to faulty welding and save pilot lives.
    I also believe that if a homebuilder does not choose to provide samples of his welds, then this hombuilder should be restricted from flying anywhere near a populated area and never be allowed to take up passengers.
    This way he will only hurt himself, if his welds fail.
    Otherwise the carnage and loss of pilot lives will continue unabated.

    Here is a quote I saw recently and it certainly applies to this forum:

    THE MORE YOU KNOW
    THE BETTER YOU KNOW
    HOW LITTLE YOU KNOW

    This little discussion has certainly changed my mind about purchasing any aircraft built or maintained in the USA by FAA certified mechanics.
    I always thought your aircraft mechanic certification was closer to ours - apparently I was misinformed.
    ISO9000 certification will be my acceptance guide, plus an in depth analysis of the log books.
    Have a happy day.

    The EAA is not a regulatory body. There is no such thing as a journeyman aircraft welder in the USA, that title does not exist. When I was looking up the requirements to me an Aircraft Maintenance Engineer in Canada I saw no mention of them being required to hold a journeyman card in welding. Is that not the case?
