J507 is a low-hydrogen sodium coated carbon steel welding electrode, which can be welded in all positions by DCEP. It has excellent welding performance with stiff arc, low spatter level, effortless slag removal ability, optimal bead appearance, and deposited metal has excellent mechanical properties and crack resistance.
The product is applicable for welding carbon steel and low alloy steel structures (under pressure and dynamic load), such as 16Mn, 09Mn2Si, 09Mn2V and A, B, D and E grade steels for ships.
