Abstract
In order to reduce the deformation of welding parts,optimize welding technics,it is necessary to forecast the thermal field of welding process.It is proved the finite element analysis(FEA) is a good method to resolve the problem.After reviewing the present research of the finite element simulation and theoretical calculation of the laser welding,a physical model for plate welding was built and its temperature field was simulated based on ABAQUS,the modeling and meshing method,boundary conditions and the simulation result were discussed.The simulation results can tell us the temperature of any point of the workpiece at any time.For a 2mm thick A3 steel plate,the simulation results are the highest temperature is 3100℃,the temperature of the point A 4mm distant from the center point of the plate is 150℃ under the condition of 2000W laser power and 20mm/s welding speed,which are in good agreement with experimental results and prove that the FEA can be used to forecast the temperature field of welding process precisely.
