State of the art of numerical simulation methods in welding

ANSYS is a large general-purpose finite element analysis software,an overview of ANSYS behavior in the welding arc, welding temperature field and numerical simulation of welding residual stress in the application of the characteristics described SYSWELD and in the application of numerical simulation of welding.Cellular automata is a kind of time,space,objects are the discrete form of the state of the dynamic model,which is the study of nonlinear science is an important research tool for a detailed overview of the Cellular Automata Method in Simulation of weld solidification,recrystallized weld simulation applications.Finally, numerical simulation of welding technology is prospected.
