采用正交试验设计和数理统计的方法,建立了焊缝截面形态的多项式回归模型,同时获得了焊缝截面几何形状参数与焊接规范参数的多元回归模型。为焊缝截面形态的预测及焊接规范参数的设计提供了依据。
By using orthogonal experimental design and mathematical statistics, a polynomial regression model of weld cross section morphology was established and a multiple regression model of weld geometry parameters and welding parameters was obtained. It provided the basis for the prediction of weld cross-section morphology and the design of welding specification parameters.
