Submerged Arc Flux features ultra-low diffusible hydrogen.

Press Release Summary:



Suitable for offshore welding joints with narrow groove angles and heavy wall thickness, Lincolnweld® 842-H™ features ultra-low diffusible hydrogen with less than 3 mL/100 g of deposited weld metal in DC and AC polarities. Impact toughness is capable of exceeding CVN values of 118 lb-ft at -76°F in body and cap pass. For cap pass welding in fatigue sensitive applications, flux features smooth bead profile with low entry angles, as well as optimized slag detachment.



Original Press Release:



Lincoln Electric Introduces a New Submerged Arc Flux with Ultra-Low Diffusible Hydrogen and Excellent Mechanical Properties for Offshore Welding Applications



Cleveland – Lincoln Electric introduces Lincolnweld® 842-H™, a submerged arc flux designed to meet the specific welding requirements for the offshore construction industry. Great for typical offshore welding joints with narrow groove angles and heavy wall thickness, Lincolnweld 842-H has excellent slag detachability and superior bead profile and smoothness.



Key Features:

Ultra-Low Diffusible Hydrogen – Less than 3 mL/100g of deposited weld metal in DC and AC polarities

Consistent Impact Toughness – Impact toughness capable of exceeding CVN values of 160 J (118 ft•lbs) at -60°C (-76°F) in the body and cap pass for consistent CTOD toughness

Outstanding Bead Profile – Smooth bead profile with low entry angles especially desirable for cap pass welding in fatigue sensitive applications

Excellent AC and DC Operation – High current capacity for single- or multiple-arc configurations

High Operator Appeal – Excellent slag detachment and wash-out

Robust Design – Allows for consistent deposit composition in a central recovery system



This neutral welding flux lowers the risk for delayed cracking and is capable of exceeding impact toughness requirements at -60°C (-76°F) and Crack Tip Open Displacement toughness at -10°C (14°F).
