The importance of purge welding

When welding stainless steel, titanium and other corrosion-resistant materials, it is important to create a perfect weld environment in order to retain the desired corrosion resistance and to eliminate weld contamination.  During welding, the heated weld seam is exposed to air and oxidizes if it is not protected. By filling the welded tube with argon, the internal potion of the tube is protected from the oxidizing atmosphere. This gives a weld that is structurally superior and lays flatter for less exhaust flow turbulence
