Supercored 70NS is used for welding in shipbuilding, machinery, bridge construcion, structural fabrication, automated or robotic welding.

Supercored 70NS is a metal-cored wire which combines the high deposition rates of F.C.W with the high efficiencies of a solid wire, provides exceptionally smooth and stable arc, low spatter and
minimal slag coverage.

① Proper preheating(50~150°C)(122~302°F) and interpass temperature must be used in order to release hydrogen which may cause cracking in weld metal when electrodes are used for
medium and heavy plates.
② One-side welding defects such as hot cracking in may occur with wrong welding parameter such as high welding speed.
③ Use Ar+20~25% CO₂gas.
