| Abstract: | By way of comprehensive analysis of distortion problems happened to welding chassis of tractors, the paper concluded that, which was resulted from the causing factors such as welding thermo-stress, residue stress and external force etc. , the measures of layers and part-specific based welding could be taken as to reduce thermo-stress, adding constraints and counter-distortlon allowance etc. |
