[Abstract]: the welding deformation of the structure not only caused the size deviation and reduce the structure bearing capacity and service life, must take reasonable precautions, reduce the maximum degree of deformation of welded structure. This paper introduces the reasons and types of welding deformation of hull structure, influence factors of welding deformation, welding process and correct the shipbuilding process, assembly welding sequence, for shrinkage deformation, rigid fixation and the prevention of the welding deformation and the deformation of the structure measures of correcting method.
