AS R-143 is a heavily coated rutile electrode. As its basic component quantity is higher than AS R-116, weld metal properties are superior accordingly. Weld metal has a high resistance to cracking. The slag is easy to remove, and it gives high quality, smooth and excellent weld beads. It is easy to strike and re-strike and thus an ideal, easy to use electrode.
AS R-143 is a general purpose electrode especially used for the welding of low and medium carbon structural steels ranging between St 33 and St 52.3. Machinery fabrications, bridge constructions; welding of boiler vessels, automotive bodies, steel furnitures, metal plate works, thin plates and small repairs are among its application areas.
