摘要：
In the present study, the duplex stainless steel (DSS) composite plate (SAF2205/16MnR) was welded by shielded metal arc welding, and the appropriate joint design and welding procedure were carried out. After welding, the mechanical behaviors and microstructure of welded joint were analyzed by using SEM and TEM. Results show that the tensile strength of welded joint satisfied the requirement, and the plate-like -phase was uniformly distributed in -Fe based solution matrix at interface between the DSS and weld metal, a carbon-rich layer and decarburized layer formed in carbon steel-weld metal interface due to migration of the element carbon. However, there were only and phases in weld metal of the joint transition layer, which is advantageous to the properties of welded joint.
