Optimized design on condensing tubes high-speed TIG welding technology magnetic control based on genetic algorithm
An orthogonal experiment was conducted by the means of multivariate nonlinear regression equation to adjust the influence of external transverse magnetic field and Ar flow rate on welding quality in the process of welding condenser pipe by high-speed argon tungsten-arc welding (TIG for short).The magnetic induction and flow rate of Ar gas were used as optimum variables,and tensile strength of weld was set to objective function on the base of genetic algorithm theory,and then an optimal design was conducted.According to the request of physical production,the optimum variables were restrained.The genetic algorithm in the MATLAB was used for computing.A comparison between optimum results and experiment parameters was made.The results showed that the optimum technologic parameters could be chosen by the means of genetic algorithm with the conditions of excessive optimum variables in the process of high-speed welding.And optimum technologic parameters of welding coincided with experiment results.
