FILARC flux- andmetal- coredwelding wiresFlux-cored wires for high strength steelsContents page 4Previous pageNext pageThe FILARC range for high strength steelscomprises 5 types with 0.2% proof stressranging from min. 500 to min. 890N/mm 2 .All types are based on the FILARCPZ 6125 formulation, with Mn, Ni, Mo or Cralloying to acquire the strength levelsneeded.The wires have good all-positional weldabilityand are well suited for welding one-sidedroot passes on ceramic backing strips.Productivity in vertical-up and overheadposition is significantly higher than withMMA or solid wire MIG welding, usingAr/CO 2 gas shielding.The table below surveys the FILARC typesfor high strength steels and their guaranteedminimum proof stress in the as weldedcondition, including relevant highstrength steel classifications and tradenames.FILARC AWS Rp 0.2% High strength steelstype classification (MPa)PZ 6145* A5.29: E81T5-G >500 EStE460-500, Weldox 460-500PZ 6146 A5.29: E91T5-K2 >550 EStE500-550, N-A-Xtra 56, HY80PZ 6147 A5.29: E101T5-K3 >620 EStE550-620, N-A-Xtra 63PZ 6148 A5.29: E111T5-K4 >690 EStE620-690, N-A-Xtra 70, Weldox 700,HY100PZ 6149 A5.29: E121T5-G >890 EStE890-960, Weldox 900-960, HY130,HY120 Mod.* CTOD testedTest welding with FILARCPZ6148 under fully restrainedconditions.64

Developed for use inAr/CO 2 shielding gas.Excellent impact values down to–50°C, with good CTOD results areobtained in both the as welded andstress relieved condition.Work in the PF position is welded inthe semi-spray arc mode, providinggood penetration. Other positions arecovered in the spray arc mode.Easy slag release.The 1.0mm size is especially suited forpipe welding in the 5G fixed position,including good root run performance.High quality root runs are economicallyproduced on ceramic backing.The weld metal hydrogen content fallswithin class H5 for all parameters.WELD METAL COMPOSITIONC : 0.05-0.09% P : ≤0.020%Si : 0.30-0.60% S : ≤0.015%Mn: 1.50-1.90%Ni : 0.60-1.00%SHIELDING GASAr/15-25%CO 2EN 439: M21WELD METAL HYDROGENEuronorm 758-95: class H5Typical value in Ar/20%CO 2: 1.9ml/100gAPPROVALSsee pages13 to17for gradesFORCETÜVUDTPOSITIONSDEPOSITION DATA IN: Ar/CO 2DiameterStickout1.0mm15mmI V wire Dep. rate[A] [m/min] [kg/h]100 5.6 1.4150 9.2 2.3200 12.3 3.1250 18.6 4.7ALL WELD METAL MECHANICAL PROPERTIESDiameter1.2mmStickout20mmI V wire Dep. rate[A] [m/min] [kg/h]150 5.8 2.1250 13.2 4.7350 22.0 7.9Diameter1.6mmStickout20mmI V wire Dep. rate[A] [m/min] [kg/h]150 2.8 1.8250 4.7 3.1350 9.0 5.9450 12.0 7.9CURRENTANDPOLARITYDC –DC +As welded PWHT 2h/600°CTensile strength, R m [MPa]: 580-680 550-650Proof stress, R p0.2 [MPa]: ≥500 ≥450Elongation, A 5 [%] : ≥24 ≥25Impact value, A v (ISO-V) – 20°C [J] : ≥100 ≥100–50°C [J] : ≥54 ≥60CERAMICBACKING65
