    non-uniform weld

    Using less than minimum prescribed fillet weld size

    the strength of the weld is in the leg size not the cross section, by reducing the size from requirement you are also lowering the safety factor of the engineering calculations. If it calls for a 1/4 welds, then a 1/4 it should be. master ICC inspector, AWS CWI

    moment welds.

    Had a meeting with the erector today, after looking at the steel, the fabricator was nice enough to slot the bolt holes about an extra 3/8 so they is some slack for adjustment. The steel erector today told me, he has done many of the bldgs, and he wasnt going to comply, he was just going to weld...

    moment welds.

    Doing a three story red iron bldg, they are hanging this week. Its loaded with moment welds, every connection. The weld is a B-u4a which is basically a groove butt weld unlimited thickness with a 45 degree and a 1/4 inch root, with backing. My question is, since the whole bldg is moment, how are...

    weld plates, I beam bearing.

    So if the bearing gap is over a 16th, I could use the argument that it violates the wps on root opening. I know the weld is suppose to be stronger than the metal welded, but would you want the whole column be supported on the weld itself. OK I can understand when the total load is applied that...

    weld plates, I beam bearing.

    This is an issue I been fight with steel erectors for years. If the weld plate is not flat the beam wont set bearing on the plate. Some will have 100% on the weld and not the plate. This is the same with K joist. I like to see 100% bearing on beams and as much as possible with k joist. My...
