Embodiment Construction
[0016] Below in conjunction with specific embodiment the present invention is described in further detail:
[0017] A rutile-type flux-cored welding wire suitable for welding low-alloy high-strength steels with a yield strength exceeding 890MPa. It is composed of a steel strip wrapped around the flux core and a flux core filled in it. There is no gap, that is, the form of seamless flux-cored welding wire is adopted, wherein the filled flux core contains slagging agent, arc stabilizing agent, alloying agent, etc., relative to the total weight of the welding wire, the filling rate of the filled flux core is 14.5-15.5%, including Has the following components:
[0018] C:0.03-0.09%, Si:0.3-0.8%, Mn:1.2-2.2%, Ni:0.5-1.5%, Co:1.0-3.5%, Ta:0.020–0.045%, REM (rare earth alloy):0.2- 0.5%, TiO 2 :2.0–4.0%, SiO 2 :0.2-0.5%, ZrO 2 :1.0–3.0%, K 2 O:0.2-0.4%; the remainder is Fe and other unavoidable impurities.
[0019] C can effectively improve the strength of the weld metal, but if...
