  • Cert for state highway bridge

    Looks like nobody knows about AWS D1.5, is any body on this forum doing welding on state highway bridges and if so what Certs are they using, I have friends that are using a DOT cert, is it a wast of time getting the D1.5 cert?
    Thanks Kevin

    The testing facilities here know about it. I heard it was around a 6 hour test. How true that is I don't know.

      Are you talking AWS D1.5 or DOT test

        The AWS. There's a whole couple hundred page book on it online. Once again I don't know what all is covered in it.

            The state DOT will have your answer. It varies quite a bit from state to state.

            Some will just accept any old AWS D1.1 or 1.5, but quite a few will impose additional conditions. Some states will designate where you have to test, consumables allowed, etc.

            The various DOT test's are all just versions of a D1.1 or D1.5 test.

            D1.1 usually applies up to the top of the pier caps and D1.5 above that. You can weld one set of coupons and get D1.1 and D1.5 out of it if the procedure is written properly.

            Not to mention any additional requirements the contract documents add.

              From what I have found the only difference in D1.1 and D1.5 is that only a Chipping hammer and wire brush is allowed for cleaning slag on D1.5

                There are other differences but yes, on the test end that's the big one.

                Some of the state dot's have unusual requirements so it's good to understand them. I know some only allow stick rod (or at least they did a few years ago). In other states there hasn't been a non semi-auto structural weld made in centuries
                I've never had a problem finding a particular state's dot rules online.

                Just be aware of any odd requirements put in contract doc's. Sometimes they clash with state requirements if engineering isn't paying attention. Those things need to be ironed out before the machine is started.

                What state are you looking at?

                    In my state (Maine), you get tested by the state DOT to do DOT work.
