Three kinds of typical welding components in the process of hull construction were chosen to analyze their flame rectification process, which, as a result, realizes the process automation. By means of analyzing process rule and establishing logic reasoning codes to generate the flame rectification method automatically; by analyzing the parameters that influence the distortion of flame rectification and welding process to build the mapping formula; and then use artificial neural network algorithm to resolve it so as to determine the critical process parameters of flame rectification. Satisfying results were achieved through the experiment in shipyard. It proves that the proposed method can improve the productivity and quality of flame rectification, and provide with the fundament for the automation of flame rectification.
