DW-A61LSR is a rutile flux cored wire that was specially formulated to meet the demands for matching S500 structural steel and P500 PV-steel. It has good toughness down to -46ºC after post weld heat treatment and fulfils Sour Service / NACE-requirement of Ni < 1,0% in weld metal.
The fast freezing slag promotes easy and very productive positional welding with slag removing easily to reveal a weld bead of smooth appearance. Typical applications are offshore constructions including S500-grades, often combined with S420- and S460-grades.
The tensile properties of DW-A61LSR make it applicable for the welding of L450 / X65 and L485 / X70-pipes, including overmatching yield strength.
