主　　题：1Cr13,1Cr18Ni9Ti Welding joint Mechanical and galvano-chemistry property 

摘      要：The purpose of this study is to discuss the microstructure and properties variation of the weld metal in the dissimilar stainless steels during the argon tungsten-arc welding *** of the existence of different materials and chemistry variation within welds,properties,such as tensile and fracture properties and so on,are expected to show spatial *** the study,microstructures were observed by optical and electron *** appearance and uniform structure and typical dendrite structure were observed in welding *** micro-hardness tester and electronic universal stretcher were used to measure the mechanical properties of the weldments and base *** heat affected zone（HAZ） near 1Cr13 hardness is up to peak value of 1150 HV,the strength of weldments is nearly same as austenite stainless *** addition,through seawater immersion test,polarization curves and AC impedance spectroscopy of the weldments and base metals are *** was found that corrosion resistance at welding joint lies between 1C13 and 1Cr18Ni9Ti.
