Numerical Simulation on Effect of Filler Material on Q345/2Cr13 Dissimilar Steel Welding
Based on the welding expert numerical simulation SYSWELD,using different filler material,numerical simulation welding between Q345 low alloy steel and 2Cr13 stainless steel was carried out under different welding temperature field and residual stress.The research results show that,the effect for welding temperature field is not obvious by using different filler material,for residual stress distribution is prominent.The measuring welding thermal cycle and the simulation.
