    Default Guide to size of electrode and bead size

    Is there a guide somewhere that specifies what size electrode to use and the proportions of the ideal bead size that you are after?
    I am trying to weld a 1/8th inch bit of plate to a 1/4 inch bit of plate at right angles and would like to know what sort of bead size should I strive for?

    2 to 3 times core wire diameter size would be ok.

    Thanks Grahame, would any particular diameter of electrode work better when welding different thicknesses of metals?

    Tiger,


    A 1/8" to 1/4" fillet weld would be best suited by using a 2.6mm electrode.

    This is to prevent burn through by a bigger electrode size .ie. 3.2mm which would well suit the 1/4" PLATE, but destroy the 1/8"plate.

    Obvious techniques are to run at the amperage best suited to the thickness
    ( practice on scrap) and maintain 2/3 rds of the wash on to the thicker plate to direct the heat away from the thin plate and avoid burn through.

    Thanks, Grahame, that makes sense.
