| Abstract: | Studied in this paper is the test of welded joints resistant to intercrystalline corrosion of identical type metal welding of 1Cr18Ni9Ti and different type metal welding of 1Cr18Ni9Ti / 16MnDR. The thesis analyses the chemical composition and microstructure of welded joints,clarifies the effect of major alloy elements,such as C and Cr,in joints seam and its construction on the anti-erosion performance of welding joints,and verifies the appropriate welding material and welding procedure. |
