    摘要
  • 摘要: 为了实现电子束焊接过程的在线监控，保证焊缝成形质量，研制了一套空间电荷信号采集处理系统，系统由传感采集模块、信号处理模块和显示分析模块组成.通过多组6061铝合金平板对接焊接工艺试验，实时采集焊缝熔池正上方8个位置的电荷，分析电荷信号波形特征与焊接成形质量关系规律，建立了波形变化对焊缝成形质量判据准则.结果表明，该系统采集的信号波形能够有效的评价焊接过程稳定性，以及实时判断焊偏、未熔合、焊穿等成形缺陷.
    Abstract: In order to realize the on-line monitoring of the electron beam welding process and ensure the quality of weld formation, a space charge signal acquisition and processing system was developed. The system consists of a sensor acquisition module, a signal processing module and a display analysis module. In this study, multiple sets of 6061 aluminum alloy plate butt welding process tests were carried out, and the electric charge of 8 positions directly above the weld pool was collected in real time. The relationship between the characteristics of the charge signal waveform and the quality of the weld forming was analyzed, and the criterion for the quality of the weld was established. The results show that the signal waveform collected by the system can effectively evaluate the stability of the welding process and determine the forming defects such as welding misalignment, incomplete fusion and burn-through in real time.
