摘要：It is important for ship production to form logical models for welding distortion. The cause of welding distortion has been analyzed. Based on the BP neural network, two mathematical models of transverse shrinkage due to butt weld and T-joint fillet weld, with input layer nodes 2, concealed layer nodes 3 and output layer node 1 are established by using experimental data of practical ship fabrication. The network structure and the training process are explained, and the examples show that the model is suitable for practice.
