Arc Welding Service

CATEGORY

TYPE

Solid wire for submerged arc welding process for welding HSLA structural steels

APPLICATIONS

Heavy construction, lifting, platforms, jackups, towers, crane building, machinery, riser pipes etc.

PROPERTIES

High strength weld deposit with good post weld heat treatment properties. S2 1NiCrMo can be used in combination with FL 851 and FL 155, both fluxes offer low hydrogen content and excellent weldabillity in multi layer welding and narrow gab.
