WPS Oscillation American Welding Society

Dec 31 Oscillation is not the same as quot width of the weld bead quot Oscillation is the amount of electrode movement Say for example the weld puddle width is 1 4 inch without oscillation and a 1 8 inch diameter electrode is used that is oscillated 2x the diameter 1 4 inch The final weld bead width would be about 1 2 inch from toe to toe
