Title:
FE-NI-CR WELDING WIRE AND PREPARATION METHOD AND WELDING PROCESS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/201891
Kind Code:
A1
Abstract:
An Fe-Ni-Cr welding wire, applied to the welding of 800H steel. The welding wire comprises a welding skin and a powder wrapped in the welding skin. The powder comprises the following components by mass percentage: Ni powder: 60.0-65.0%; Cr powder: 15.0-20.0%; Mn powder: 8.0-10.0%; Ce powder: 0.01-0.05%; the sum of the mass percentages of Nb powder and W powder is 3.0-4.0%; and the rest is Fe powder; the sum of the mass percentages of the above components is 100%; and the core filling rate of the welding wire is 30-35%, and the welding skin is a 310S stainless steel strip. Further comprised are a preparation method for an Fe-Ni-Cr welding wire and a welding process for an Fe-Ni-Cr welding wire. After using the described welding wire to weld an 800H base material, the welded joint can ensure high tensile strength, elongation and good sealing performance of a welded part under normal temperature and high temperature conditions.
