General Review on Prediction of Welding Distortion of Construction in Naval Architecture

In this paper,the development and current situation of theories on welding distortion prediction,which were classified to three symbolic development stages: based on theoretical and empirical experiments;based on numerical simulation;based on data mining,have been discussed.Detailed comparative analysis of these methods in different stages also has been done to discuss their advantages and disadvantages in the application.The prospect of data mining used in the prediction was especially introduced with the ...
