The Mechanical Properties of High Speed GTAW Weld and Factors of Nonlinear Multiple Regression Model Under External Transverse Magnetic Field
A transverse magnetic field was introduced to the arc plasma in the process of welding stainless steel tubes by high-speed Tungsten Inert Gas Arc Welding (TIG for short) without filler wire.The influence of external magnetic field on welding quality was investigated.9 sets of parameters were designed by the means of orthogonal experiment.The welding joint tensile strength and form factor of weld were regarded as the main standards of welding quality.A binary quadratic nonlinear regression equation was established with the conditions of magnetic induction and flow rate of Ar gas.The residual standard deviation was calculated to adjust the accuracy of regression model.The results showed that,the regression model was correct and effective in calculating the tensile strength and aspect ratio of weld.Two 3D regression models were designed respectively,and then the impact law of magnetic induction on welding quality was researched.
