Abstract: Loader tiger exists a prominent question of welding deformation. To reduce this welding deformation and get the optimal scheme of tiger shaped structure welding sequence,the numerical simulation of welding deformation of tiger-shaped structure for rear frame of loader was conducted using thermo elastic-plastic method. The finite element model was established to analyze four kinds of deformation trend of tiger shaped structure and quantitatively calculate the distortion of different welding sequence, the optimal welding sequence of the whole structure was obtained. The results show that the maximum deflection distortion of side arm was 8 mm,the torsional deformation of frame was 4 mm,the in-plane shrinkage of side arm was 12 mm.The simulated values and measured values are compared under the optimal welding sequence,and the results show that they are in good agreement.
