Temperature Field of In-service Welding of Stainless Steel Pipes

XUE Xiao-long1 ,LUO Xiao-ming1 ,YAO Jian-ping1 ,SANG Zhi-fu2(1.Shanghai Institute of Special Equipment Inspection and Technical Research,Shanghai 200062,China;2.College of Mechanical and Power Engineering,Nanjing University of Technology,Nanjing 210009,China)  
Temperature field of in-service welding was measured by thermal-couples and simulated by FEM.The material property change with the temperature,the convection and radiation boundary conditions were considered.The effect of internal flowing media on temperature field was defined as a forced boundary condition.The numerical simulated and experimental results accord with each other.It can be concluded that the temperature field of in-service welding can be simulated accurately by FEM.
