The application of Kalman filtering for the weld detection in the arc welding process is presented. A Kalman filter is applied for processing the arc weld pool images from a visual sensor to recursively compute the solution to the weld position equations which are established based on an estimation of the position and displacement of the centroid of the weld pool images. 提出一种基于卡尔曼滤波技术的电弧焊焊缝检测新方法。利用视觉传感器获取弧焊区熔池图像,并抽取图像质心作为描述焊缝位置的特征矢量,建立图像质心状态方程和测量方程。在有色噪声模型的基础上,应用卡尔曼滤波对图像质心位置和质心位移进行状态估计,得到最小均方差条件下的焊缝位置最佳预测值,从而减小过程噪声和测量噪声引起的焊缝位置测量偏差,实现弧焊过程中焊缝位置的精确检测。

The effect of Al on inclusions, microstructure and mechanical properties of weld [I]meta[/I]l of self-shielded flux cored wire with high Al content BaF_2 slag was investigated. The experimental results reveal that the average size of the inclusions grows with the increase of Al component in the weld [I]meta[/I]l, and the inclusions in weld [I]meta[/I]l mainly consist of AlN and Al_2O_3; the inclusions in the weld with low Al concentration are predominantly Al_2O_3 通过光谱分析、Luzex.F图像分析、扫描电镜、能谱分析、力学性能试验等手段,研究了高铝BaF2渣系自保护药芯焊丝焊缝中的Al含量对焊缝中夹杂物、微观组织和力学性能的影响.研究结果表明:随焊缝中的Al含量增高,焊缝夹杂物平均尺寸增大;焊缝中的夹杂物以AlN和Al2O3为主,在低Al焊缝中以Al2O3为主的夹杂物较多
