JQ-E7018 ISO 2560-A-E 42 3 B 42 H5AWS A5.1 E7018H4 Introduction： JQ-E7018 is a carbon steel welding electrode with Fe powder and low-hydrogen potassium coating, which is designed for vertical down welding work. AC/DC both can be applied.The welding electrode has excellent welding performance with smooth arc, optimal appearance, extreme low spatter level and effortless slag removal ability. The deposited metal has stable mechanical properties, good plasticity and low temperature impact toughness; also it has low diffusion hydrogen content and good crack resistance. Purpose： The product is applicable for welding carbon steel and low alloy steel structures such as marine engineering, ships, storage tanks, pressure vessels and bridges.
