    Weld Strength

    While I was deciding whether to leave a joint alone, or reinforce it, I was skimming through some material in the Bible.

    While this only covers fillets, gotta remember that probably 80% of the welding anybody does is a fillet.

    I can't put my fingers on it, but I also remember seeing that fillets are generally analyzed in shear. It was stated that all weld failures in the weld itself, not the base material, are in shear......regardless of the direction of the applied load.

    The table, and method, is highly simplified, but ought to give the average guy like me (not math oriented) a few numbers to work with. At least it's some insight into sizing of welds.

    I guess we were spoiled on the job. Always worked off engineered drawings. All we needed was a set of these.
