J422
Introduction:
The J422 is a lime-titania coated carbon steel electrode that is specially designed for facial welding on low alloy steel structures. The welding rods are suitable for all-position welding and they produce a glossy, beautiful weld. The electrodes provide a stable are, easy re-ignition, excellent fluidity and minimal slag that is quickly detachable.
Applications:
The J422 carbon steel electrode is used for welding structures with strict appearance requirements, such as, ships, vehicles, construction machinery, etc.
