The root surface of a weld that is prepared on both sides may need to be ground or gouged clean before the next weld pass(es) to ensure proper penetration and fusion. If the surface is not properly cleaned, it can lead to defects in the final weld. Sanded smooth may not be sufficient to remove any contaminants or potential defects. Re-tack welding may not address issues with the root surface. Nothing, it will be on the back anyway is incorrect as issues with the root surface can still affect the overall quality of the weld.
