OK Autrod 12.22 SAW Copper-coated, unalloyed wire for Submerged Arc Welding. Suitable in combination with most fluxes. Increased Si content and thus especially for neutral fluxes (e.g: OK Flux 10.62) or in order to increase the fluidity of the molten pool. For structural steels, ship buildings steels, preassure vessel steels, fine grained steels, etc. Classifications Approvals Typical all weld metal composition, % Typical mech. properties all weld metal SFA/AWS A5.17 EM12K EN ISO 14171-A S2Si DB 52.039.05 CE EN 13479 VdTüV 12103 APPROVALS NAKS/HAKC 2.0, 2.5, 3.0, 4.0, 5,0mm C 0,1 C 0,1 Si 0,2 Si 0,3 Mn 1,0 Mn 1,0 Wire composition Diameter, mm 2,0 2,5 3,0 4,0 5,0 Diameter, mm 2,0 2,5 3,0 4,0 5,0 6
