E7018 electrode and J506 electrode are basically the same in two kinds of materials, and the composition and performance are almost the same, different places in E7018 is a low-carbon steel electrode of iron powder and low hydrogen type coating, AC and DC, can be all-position welding. Its characteristic is that the coating contains iron powder, and the weld deposition coefficient is large, which can reduce the number of welding layers.
J506 electrode is a low-carbon electrode type low-carbon steel electrode with good mechanical properties and crack resistance. It can be used for all-position welding in both AC and DC applications. When AC welding, its arc stability is slightly inferior to DC welding.
