Description: AFM E7024 is a high speed, heavy-coated, iron powder electrode. The coverings usually amount to about 50% of the weight of the electrode, resulting in higher deposition efficiency.
Welding Characteristics: AFM E7024 electrodes are characterized by having a quiet arc, very low spatter, low arc penetration and are well suited for making fillet welds in the flat or horizontal position. The weld face is slightly convex to flat and has a very smooth surface with a very fine ripple. They can be used with high travel speeds.
Applications: AFM E7024 can be used on mild and some alloy steels used in earth-moving and construction equipment, truck bodies, ships, barges, and railcars.
