Review on prediction and control welding distortion of ship structure

Welding distortion control of ship structure is a vital component of precision shipbuilding.It is significant to improve ship quality and to shorten building period.Process of research and application on prediction and control welding distortion of ship structure is reported.Various numerical simulation methods and features about prediction welding distortion have been discussed.The anticipation of thermo-elastic-plasticity finite element method and inherent strain method in shipbuilding has been represented detailed.Measures of control welding distortion have also given.Thus,precision shipbuilding technology could be promoted in shipyards.
