Welding method for dissimilar stellite trace alloy elements

The invention provides a welding method for dissimilar stellite trace alloy elements, belongs to the field of welding, and aims to solve the technical problems of dilution rate, quality stability, service life and the like of stainless steel in a surfacing process. And the input and the outflow of elements in the welding process are in a high-quality range, so that the hardening degree of a welding seam and a heat affected zone is reduced, the wear resistance, the corrosion resistance and the crack resistance of the welding seam are improved, the generation of harmful components is inhibited, the product is prevented from generating low-melting-point eutecticum such as M23C6 and the like to cause grain boundary cracking, meanwhile, a surfacing layer can be ensured to have higher strength, and the welding quality is improved. And the long-term use performance of the product can be met and improved under high-temperature, high-pressure and complex working conditions. 本发明提供了一种异种司太立微量合金元素的焊接方法，属于焊接领域，目的是解决不锈钢在堆焊过
