J502WCu

According with GB E5003-G


Introduction: J502WCu is a kind of low-alloy atmospheric corrosion-resistant steel electrode with lime-titania type coating. AC/DC. All-position welding. It has excellent welding performance, excellent mechanical properties, stable arc, fewer spatters, good slag detachability and beautiful appearance of weld. The weld metal has excellent atmospheric corrosion-resistance.


Uses: Specially used for welding atmospheric corrosion-resistant steel on railway locomotive vehicles, such as 09MnCuPTi, etc.
