摘要：
The adaptive control method was used in aluminum alloy pulse gas tungsten arc welding (TIG) to control penetration. The specialties of the TIG welding process for aluminium alloy were analyzed. The stochastic system theory was introduced into the welding process, the stochastic models between welding condition and the parameters of weld pool were established and the on-line identification of the model parameters was realized. Moreover, adaptive welding current adjuster based on the minimum variance theory was designed. The experiments show that the adaptive system is excellent in controlling weld bead for aluminium alloy TIG welding.
