J502NiCu
J502NiCu is a low-alloy weather-resistant steel welding electrode with titanium-calcium coating, which adopts DCEP connection method and is permitted for all positions welding. It has excellent welding performance with smooth arc, low spatter level, effortless slag removal ability and optimal bead appearance. The deposited metal has good mechanical properties and atmospheric corrosion resistance.
It is applicable for welding weather-resistant railway vehicles, such as 09MnCuPTi and 16MnCu.
