摘要
Abstract
The medium carbon steel 40MnB has advantage physical properties such as high strength and good toughness,but its high carbon content lead to bad weldability and high cold cracking tendency.The low alloy high strength steel 16MnR has good physical properties and weldability.The dissimilar welding joints between 40MnB and 16MnR are widely used in automobile industry.The dissimilar steel between 40MnB and 16MnR are welded by Carbon dioxide gas shielded arc welding.The microstructures and properties of welded joints are analyzed by means of optical microscope,mechanical properties and nondestructive testing.Results show that grain growth is not serious in Heat-Affected Zone and good fusion between weld and base material.Based on the present work,it is concluded that Carbon dioxide gas shielded arc welding is the suitable welding procedure for dissimilar metals between steel between steel 40MnB and 16MnR.关键词
