Submerged arc flux for offshore welding

Share This Post

Lincoln Electric has introduced a new submerged arc flux designed for welding requirements for the offshore construction industry.

Suitable for typical offshore welding joints with narrow groove angles and heavy wall thickness, the Lincolnweld 842-H has excellent slag detachability, superior bead profile and smoothness, claims the company.

It features ultra-low diffusible hydrogen, less than 3 mL/100 g of deposited weld metal in DC and AC polarites. Impact toughness is capable of exceeding CVN values of 160 J (118 ft/lb at 60 degrees C (-76 degrees F) in the body and cap pass for consistent CTOD toughness. It produces a smooth bead profile with low entry angles for cap pass welding in fatigue sensitive applications. It has high current capacity for single or multiple arc configurations. 

The neutral welding flux lowers the risk for delayed cracking and is capable of exceeding impact toughness requirements at -60 degrees C (-76 degrees F) and crack tip open displacement toughness at -10 degrees C (14 degrees F).
