QuNi29 Bobbin – Laser Welding Wire Pure Nickel Ni99.7 (2.4060) – Titanium-Free

QuNi29 is a pure nickel alloy Ni99.7Mg (material no. ~2.4060) for joint and build-up welding on commercial pure nickel grades, LC nickel, nickel alloys and nickel-clad steels.The difference from QuNi40 is stated in the datasheet: this wire is pure nickel without titanium. Where the electrical and thermal conductivity of nickel matters, this is the right choice. Where dissimilar joints to steel or cast iron repairs are involved, use the titanium-alloyed QuNi40 — its titanium binds nitrogen and prevents porosity.Recommended base materials2.4060, 2.4061, 2.4066, 2.40682.4052, 2.4053Commercial pure nickel grades, LC nickelNickel-clad steelsTypical applicationsPressure vessel and plant constructionChemical industryFood industryEnergy sector — where conductivity is requiredProperties and advantagesNi 99.7 % — pure nickel, no titanium additionGood corrosion and temperature propertiesPreserves the electrical and thermal conductivity of nickelMagnesium micro-alloyed (0.03–0.07 %) for clean weld metalRod form advantage: Constant wire feed for manual repair welding on vessels and apparatus.Rod form: Rod lengths 1000 mm and 333 mm, Ø 0,2 mm – 0,8 mm.

QuNi40 is the titanium-alloyed nickel wire: EN ISO 18274 S Ni 2061 (NiTi3) · AWS A5.14 ERNi-1 · filler material no. 2.4155.The 3.3 % titanium is what sets it apart from the pure QuNi29. Titanium binds nitrogen and thus suppresses porosity — precisely what is needed for nickel-to-steel dissimilar joints and for repairs on grey cast iron (GG-GJL), where gases migrate from the base material into the weld pool. For matching pure-nickel joints without such influence, QuNi29 is the simpler alternative.Recommended base materials2.4060, 2.4061, 2.4066, 2.4068Commercial pure nickel grades, LC nickelNickel-clad steelsNickel-to-steel dissimilar jointsCast iron (GG-GJL) — repairs possible to a limited extentTypical applicationsPressure vessel and plant construction, chemical industryNickel-to-steel dissimilar jointsGrey iron repairs (GJL)Food industry, energy sectorProperties and advantagesTi 3.3 % — binds nitrogen, suppresses porositySuitable for nickel-to-steel dissimilar jointsGrey iron repairs possible to a limited extentWeld metal: Re 300 MPa · Rm 450 MPa · A 25 %Bobbin form: K125, K250, K80, MA125, SH253 — wire weight 100 g–500 g, Ø 0,2 mm – 0,8 mm.
