Displacement Field Simulation and Deformation Prediction of Longitudinal Straight Seam Welding of Thin-Wall Aluminium Alloys Cylinder
The numerical simulation calculation of longitudinal seam TIG welding of thin-wall aluminium cylinder was conducted by the FEM software, Marc. Based on the generating of analysis model, displacement field was quantitatively described. Circular profile of aluminium alloy cylinder after welding was predicted by the radial displacement. The simulation results showed that the post-weld deformation for the longitudinal seam of aluminium alloy cylinder was mainly destabilizing deformation.
