Weld width prediction based on artificial neural network

The method of weld width prediction based on artificial neural network(ANN) was studied,and the weld quality could be estimated by it.Problems and questions relating to the welding process monitoring system were considered,such as picking up the characteristics of arc welding,welding quality prediction and the application of ANN.The welding quality monitor system based on ANN was designed and its composing structure was given.The weld quality prediction model based artificial neural network is build up,and simulation is given.The results of simulation showed that the ANN model could predict the weld width,and the welding quality monitor system based on ANN was efficient.
