E7028 is an iron powder, low hydrogen electrode developed for high deposition efficiency welding of flat and horizontal fillets, as well as deep groove joints in 71,000 psi, high tensile strength steel. This electrode produces X-ray quality weld deposits which exhibit high cracking resistance and excellent mechanical properties. In addition to its high deposition rate, E7028 provides easy slag removability and a nice bead appearance, free from undercuts. Welding efficiency can be further improved by using a gravity welder. This electrode can be used with AC or DC (reverse polarity). E7028 is used for welding strength members of ship hulls, bridges, heavy machinery parts and fired or unfired pressure vessels
