  • Taking the fillet weld of the dust removal system of the TX-18 railway track bed as a model, Ansys is selected to simulate the fillet welding process of the dust removal system. Through the instantaneous temperature field, welding residual stress and plastic deformation cloud graph, the influence of the welding process on its deformation is studied. Based on the calculation results and the actual weld length considerations, the anti-deformation amount is controlled to 5-10 mm, and after the welding stress is removed by annealing, the surface flatness of the dust removal system can be controlled within 2.5 mm, which can meet the design requirements of the dust removal system.
