Solid welding wire for Duplex (2209, 1.4462)

Solid Duplex welding wires are usually welded in almost the same way as the standard stainless steel grades, when using gas for backing a nitrogen containing gas is preferred. Usually the weldabillity of solid Duplex welding wires is a little worse than normal stainless steel wires and impulse arc welding is recommended. Flux cored Duplex welding wires do not have this problem, they offer excellent wetting, less spatter and 2 times more productivity in PF position. Recently we extended our range with a special new development of a flux cored welding wire for Duplex with extreme high impact values at temperatures down to -50ºC, see datasheet of AA 2209 Pi
