Weld bead blending, take down, or flattening can be done with a 50, 60, 80, or 100 grit abrasive disc, flap disc, or belt. Weld defects could also be removed with 50 to 80 grit abrasives. Try leveling weld or parting lines with an 80-grit abrasive product first. If metal removal is too slow, then go to coarser grits.Web
