| Abstract: | Following a theoretical analysis of the welding process of metal structure, a computer program for the calculation of the welding deformation is described in this article. Then a finite element model for the main beam of 936E loader rear frame is established and computation is carried out according to different welding sequence. Satisfactory accordance between calculation and experimental results so that a reliable basis is provided for the control of welding deformation and the preparation of welding schedule of metal structures. |
