焊缝截面形态的数学模型、预测与焊接规范参数的设计

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 of orthogonal experiment design and mathematical statistics, make the multinomial regression model of welding section form and the multivariate-regression model of welding section geometry form parameters and welding process parameters. These models not only establish a basis for the forecasting of welding section form, but also furnish a basis in the designing of welding process parameters.
