Popis: | An experimental and numerical investigation of double laser beam bilateral and simultaneous welding is carried out in this paper. A dedicated heat source model is developed based on a combined heat source with coordinate transformation and mirroring. Several groups of heat source parameters are assigned, and the simulated results based on these heat source parameters are compared with the experimental results. The deformation after welding for a seven stringers welding panel is predicted by finite element analysis. To optimize the welding sequence, four welding schemes are applied to the simulation. Comparing the simulated results, the scheme 3 is thought to be the best weld sequence for the smallest welding distortion. |
