Pipe Welding Covered Electrode is suitable for welding high strength pipe. The Electrode is an all position cellulosic electrode that has high tensile strength. The Pipe Welding Covered Electrode produces the consistent, deep penetration required to maintain a proper keyhole when vertical down welding in open root pipe joints. Pipe Welding Covered Electrode comes in different sizes like 2.50 X 350mm, 3.25 X 350mm, 4.00 X 350 mm and 5.00 X 350mm.
