CHEN Zhiyuan, FU Qiang, ZHU Yaqiong, et al. Research on the on-line detection technology of all position manual welding line energy[J]. Eletric Welding Machine2020, 50(3): 24-27.DOI: 10.7512/j.issn.1001-2303.2020.03.04.
An on-line detection method of line energy is proposed for the problem that the welding line energy can not be accurately measured in real time in the manual welding process. A flexible arc light capturing mechanism is designed
which can adapt to different beads in all position manual welding. The conversion technology from arc light signal to electrical signal is emphatically studied
and then a signal processing system with STM32 single chip microcomputer as the control core is built to realize the realtime display of digital quantity of welding line energy. The welding test shows that the method has good real-time performance and the detection precision meets the requirements.
