J422
J422 According with GB E4303
Introduction: J422 is a kind of carbon steel electrode with lime-titania type coating specially used
for facial welding or low-alloy steel/low mechanical property requirement steel as 09Mn2. AC/DC.
All-position welding. lt has glossy and beautiful appearance of weld, excellent mechanical properties,
stable arc, easy re-ignition, good fluidity and detachability of slag.
Applications: Applicable for welding the structures with high appearance requirements, such as
ocean platforms, ships, vehicles, construction machinery, etc
