微机控制熔化极脉冲窄间隙焊缝自动跟踪系统从窄间隙焊的实际出发,设计了一种以坡口棱边为依据的新型跟踪传感器——光电数字传感器,该传感器能直接以数字形式给出偏移量的大小,且体积小、抗干扰能力强,并以单板计算机为主体组成控制系统,有效地实现了对焊缝的跟踪. (西北工业大学陆依成等) 高频脉冲TIG辉电弧阳极行为的研究对高频脉冲TIG焊电弧阳极的平均电流密度分布及其中心电流密度动态过程进行了测定及研究,并建立了数学模型。还利用自制的微压测试装置,研究了高频脉冲TIG焊电弧阳极轴向压力的分布,建立了数学
Based on the actual situation of narrow gap welding, a new type of tracking sensor based on bevel edge is designed, photoelectric digital sensor, which can be directly given in digital form Offset size, and small size, strong anti-interference ability, and the single-board computer as the main component control system, the effective realization of the weld tracking. (Northwestern Polytechnical University Lu Yicheng, etc.) high-frequency pulsed TIG glow arc anode Behavior The average current density distribution and the center current density dynamic process of high-frequency pulsed TIG arc anode were measured and studied, and a mathematical model was established. The self-made micro-pressure test device was also used to study the distribution of the axial pressure in the pulsed TIG welding arc anode. A mathematical
