AWS E7018 is a carbon steel electrode with iron powder type coating. Both alternative current(AC) and direct current (DC) can be applied. It can be welded in all positions. The welding performance is excellent. The arc is stable. The welding spatter is small and the welding slag is easy to remove. The welding bead appearance is beautiful. Welding deposits exhibits high efficiency. AWS E7018 can be used for welding low carbon steel and low alloy steel structure. It must be baked at 350-380 degrees Celsius for 1 hour before use. It can be used anytime after bake. And the amplitude should not be too large.
