摘要：在复杂空间曲线的多层多道焊接过程中，每层道的焊道都会影响最终焊缝成型质量，而焊缝成型质量与焊接工艺参数相关。为了探究此种关系，搭建了以氩气作为保护气体的单道熔覆试验平台，根据对13组试验结果的分析，获得了各焊接工艺参数与焊道成型参数的影响规律，发现焊接电流保持不变，焊道横截面积、熔宽、余高都随着焊接速度的减小而增大，当焊接速度保持不变，焊道横截面积、熔宽、余高都随着焊接电流的减小而减小。采用二次旋转组合设计的方法建立数学模型，预测焊道成型参数以及根据焊道信息确定焊接工艺参数，将焊接速度作为模型的输入，焊接横截面积、余高、熔宽作为模型的输出，对该模型进行回归检验，并经过反编码计算得到输入与输出的关系表达式。最后，基于模型得到了焊接工艺参数与焊道成型参数的关系曲线图，为后续的焊接工艺参数选择以及多层多道焊路径规划提供理论指导。

Abstract：In welding process with complex spatial curves, the weld passes of the multi-layer welding affect the quality of the final weld formation. The weld formation quality is related to the welding process parameters. In order to explore this relationship, a single-pass cladding test platform with argon as the shielding gas was built. According to the analysis of 13 sets of test results, the influence laws of each welding process parameter and weld bead forming parameter were obtained. It was found that when the welding current remains constant, the cross-sectional area, fusion width and reinforcement of the weld bead increase with the decrease of the welding speed. When the welding speed remains constant, the cross-sectional area, fusion width and reinforcement of the weld bead decrease with the decrease of the welding current. The mathematical model is established by the method of secondary rotation combination design. The weld bead forming parameters are predicted and the welding process parameters are determined according to the weld bead information. The welding speed is taken as the input of the model, and the welding cross-sectional area, reinforcement and weld width are taken as the output of the model. Regression test is carried out on the model, and the relational expression between input and output is obtained through reverse coding calculation. Finally, based on the model, the relationship curve between welding process parameters and weld bead forming parameters is obtained, which provides theoretical guidance for subsequent welding process parameter selection and multi-layer multi-pass welding path planning.
