    Default Help with Lap joint on 1/2" plate

    Let me start by saying I don't know what is best when doing stick welding since I don't do a lot of it so please be kind. I am about to weld some W8x24 beams to 8"x8" anchor plates with a lap joint and going to use a gas powered SMAW machine. What type and size rod would be best for this application and would multi passes be required or is there a rod that is large enough that a single pass would do.

    Thanks in advance for your help.





    The only person that can be considered ignorant is the one that knows that they don't know and doesn't ask some one who does.

    An answer would depend on your machine current output and welding position.

    I would run 5/32 6010 first pass around the beams 1/4" web and 3/8 flanges and use either 1/8 or 5/32 7018 to complete the fillet welds.

    I don't understand where lap joints are going?

    I'm thinking the 1/2" anchor plates will be welded to the end of the W8X24 beams and be bolted to a floor or another beam.

    I'm thinking they will be lap joints because he said these are to be beams, not columns.

    Thanks chewinggum for trying to straighten me out but I still don't get it. South Carolina people are the best, never ran across one that wasn't polite and helpful.

    Do you have a home made BBQ? I wish I could come down and eat some South Carolina BBQ with ya, tackit

    Default More Explaination

    There will be W8x24 beams spanning 20' and resting on 1'x1' columns.
    under the beams will be anchor plates 8"x8"x1/2" that the beams will sit on
    and need to be weldedDetail.jpg

    I hope this is more clear.
