摘要
介绍了一种铝合金点焊过程电压、电流、声音和电极位移信号的实时采集系统,并给出了该采集系统所采用的传感器和数据采集卡等硬件构成原理和使用虚拟仪器设计软件LabVIEW编制的程序框图。试验表明:该采集系统能够正确采集铝合金点焊过程的各个特征信号,并能有效反映焊接过程中焊点熔核的变化,可以满足点焊过程实时监测的要求。
This paper introduces the real-time acquisition system of vohage,current,sound and electrode displacement signals in aluminum alloy spot welding and presents on the composition of sensor and data acquisition card and the program frame by using ~irtual instruments design software LabVIEW.The system is able to acquire the characteristic signals,effectively reflect the change of welding spot nugget during the welding process and satisfy the real-time measurment in spot welding process.
