摘要
由于CO2短路过渡焊接过程是一个非线性、时变的过程,所以对其焊接工艺参数的优化研究一直是焊接界的热点。运用正交试验,结合自行研制的焊接电弧动态小波分析仪对焊接电流、电弧电压、焊接速度等主要焊接工艺参数进行了优化研究。根据试验结果分析了主要焊接工艺参数与焊接质量之间的关系,为焊接工艺参数的优化及焊机性能的改进奠定了必要的基础。
The CO_2 short circuiting transfer welding is a non-linear and time-variant process , so the optimization of its welding parameters is a focus in the field of welding. The main welding parameters such as welding current, arc voltage and welding speed have been optimized by the orthogonal test and welding arc dynamic wavelet analysis instrument. The relationship between the main welding parameters and welding quality were analyzed according to the experiment results, and it laid the groundwork for the optimization of welding parameters and the promotion of welding performance.
