摘要
采用回归正交试验设计方法建立了细丝ＣＯ２气体保护焊短路过渡时焊缝几何形状和尺寸与焊接工艺参数即电弧电压、焊接电流、焊接速度、焊枪角度、干伸长度间关系的数学模型．在试验范围内，该模型可预测焊缝几何形状，或根据对焊缝成形的要求对焊接工艺参数优化选择，以及控制焊缝形状。
By using fractional factorial techniques mathematical models have been developed to predict the relationships between the weld bead geometry and dimensions and welding parameters such as arc voltage,welding current, welding speed,gun angle,and the distance from nozzle to plate.These models can be used either to predict the bead geometry resulting from any combination of welding parameters within the range studied or to determine a combination or a range of parameters to obtain the dimensions of the desired bead geometry.However,these models can also be used in a production system for automatic control of welding conditions.
