E6020 welding rod is a high iron oxide welding electrode used for stick welding applications. The main benefits of E6020 welding electrode are the high weld deposition and higher travel speed.
E6020 welding rod is similar to E6022 but they can be used for single pass and multipass welding. However, E6022 can only be used for single pass welding applications.
Due to low viscosity of the welding slag, E6020 welding electrode is limited to be use in Flat and horizontal welding positions.
