【Abstract】 Weld geometric dimension and the structural performance are determined by welding procedure parameters, so it is important to design welding procedure parameters for weld structure production. Based on numerical simulation and neural network, a BP neural network system to design welding procedure parameters is built,in which weld quality information(weld geometric dimension and cool time) is the input parameter, while welding procedure parameters are the output parameters. Performance of this system is tested and validated.更多还原
