Abstract

En kjernetråd, dannet av en hul ståltråd, tiltenkt å fremstille et sveisemetall som har en 0,02% konvensjonell flytgrense (?0,2) på 620 MPa eller over og en Charpy slagfasthet vE-60 ved -60?C på 50 J eller over for gasskjermet lysbuesveising. Kjernetråden inneholder 0,02 til 0,15 % av masse C, 0,3 til 1,4 % av masse Si, 1,2 til 3,5 % av masse Mn, 0,2 til 3,4 % av masse Ni, 0,02 til 2,0 % av masse Cr, 2,0 til 6,0 % av masse Ti, 0,1 til 2,2 % av masse Mo og 0,01 til 1,0 % av masse Mg. Et flussmiddel inkludert i kjernetråden inneholder TiO2 og MgO, slik som å møte ulikheten: (TiO2) / (MgO) > 4,7, der (TiO2) og (MgO) er TiO2-innholdet og MgO-innholdet i kjernetråden tilsvarende de henholdsvise forhold i masse av TiO2 og MgO holdt i flussmiddelet til kjernetråden.A core wire, formed from a hollow steel wire, intended to produce a weld metal having a 0.02% conventional flow limit (? 0.2) of 620 MPa or above and a Charpy impact strength vE-60 at -60 ° C at 50 J or opposite gas shielded arc welding. The core wire contains 0.02 to 0.15% of pulp C, 0.3 to 1.4% of pulp Si, 1.2 to 3.5% of pulp Mn, 0.2 to 3.4% of pulp Ni, 0.02 to 2.0% of mass Cr, 2.0 to 6.0% of mass Ti, 0.1 to 2.2% of mass Mo and 0.01 to 1.0% of mass Mg. A flux included in the core wire contains TiO2 and MgO, such as to meet the inequality: (TiO2) / (MgO)> 4.7, where (TiO2) and (MgO) are the TiO2 content and the MgO content of the core wire corresponding to the respective conditions in mass of TiO2 and MgO held in the flux of the core wire.
