| Abstract: | Fusion penetration for 5A06 Electronic Beam Welding(EBW) is predicted based on Articial Neural Network(ANN) .Based on adaptive network model and network structure,and selected trainning algorithm and times,a BP neural network mapping model from accelerating voltage,beam current and welding speed to fusion penetration is established.Training samples are obtained by using orthogonal experiment and normalized for reducing prediction error.The trained network can predict fusion penetration in a definite range through GUI,which has good verifying precision. |
