摘　　要：传统的火焰钎焊温度依靠人工目测的方法来判断,容易造成高温过焊、欠温漏焊的产品缺陷。该文以异型薄壁铜管的钎焊温度控制为研究对象,提出了一种基于红外线测温和PLC控制方法,设计了钎焊温度实时监控系统,给出温度信号监控流程,有效提高钎焊温度精准性,保证了在不同钎焊环境下对焊件温度的监控。The defects of traditional flame brazing temperature is to judge by visual,which will cause heated welding products.Taking the special-shaped thin-walled copper brazing temperature control as the research object,this paper proposes a controlled method based on infrared temperature test and PLC,and designs the real-time monitoring system for brazing temperature to monitor by temperature signal,in order to improve the accuracy of brazing temperature and ensure butt welding temperature monitoring under the environment of different brazing.
