Mild Steels Electrodes
ES 7024 GW A5.1: E 7024 / EN 499: E 42 0 RR 73
Description
ES 7024 GW It is a heavy coated, high efficiency rutile iron powder electrode. It gives a metal recovery of about 180 % due to high iron powder content in its coating. It is particularly suitable for GRAVITY welding of thick plates. It gives smooth weld bead appearance with a soft arc. The slag is easy to remove. Recovery 180.

Applications
It is used for the welding of mild steels having a maximum tensile strength of 440 N mm˛, Ana for ordinary ships plate of A- and D- quality. It is an ideal electrode particularly used for welding fillet and butt join in flat and horizontal positions. Machinery fabrication and ship building where smooth weld beads are required; boiler and pressure vessel manufacturing; automotive bodies and steel and bridge constructions are among some application areas where It is extensively used. It brings high efficiency as it is a very high position rate
