A term generally applied to welding applications in which all of the filler metal is deposited from one side. The resulting welds are usually free of imperfections on the backside so that it should not be necessary to do any welding on the backside. Submerged arc welding (SAW) has been considered a “one-sided” method. For the most part, welding can be completed from one side, but sometimes there may be imperfections that necessitate back-chipping or gouging and welding on the underside.
