SMAW Welding Tips on Electrode Classification
(252 votes)Welding Equipment
We report hereafter a few SMA-welding-tips on characteristics of covered electrodes of specific types:
E6010: suitable for direct current electrode positive (DCEP). Recommended for all welding positions with substantial penetration. The slag is thin, easily removable.
E6011: designed for use with alternating current (AC), to reproduce the characteristics and mechanical properties obtained with E6010.
E6012: may be used with direct current electrode negative (DCEN), suitable for vertical welding with low penetration and dense slag. May produce higher yield strength and lower ductility than the first two above.
E6013: can work with AC at low amperages and low open circuit voltage. Suitable for light sheet metal welding with low penetration. Easy slag removal. Otherwise similar to E6012.
E6019: electrodes of this type provide deep arc penetration with good ductility. Meet requirements for radiographic standards and specific impact properties at low temperature. Suitable for use with all currents (AC, DCEP or DCEN).
E6020: suitable only for flat or horizontal fillet position welding on thick material because of low viscosity slag. Medium to deep penetration depending on current level. With iron oxide in the covering.
E6022: suitable for flat and horizontal single pass welding at high speed with high current.
E6027: suitable for thick base metal in flat and horizontal position with all types of current with medium penetration. Thick cover containing iron. Easily removable slag.
E7014: similar to above E6012 and E6013 but usable at higher amperage. With iron powder in the covering to increase deposition efficiency. Suitable for all positions and wide root gap due to poor fit. Easily removable slag.
E7024: With iron powder in the covering, suitable for all types of current,low arc penetration. High travel speed possible.
E7024-1: Similar to the above (without suffix) but for greater ductility and lower Ductile to Brittle Transition Temperature.
E7027: Similar to E6027 but with higher mechanical properties. Must meet specified requirements on chemical composition.
