美国陆军建设工程研究室(CERL)和依里诺斯大学的无线电研究室一起研制了一种能监测焊接过程参数并提供连续的图象或打印输出的焊接质量监测仪(WQM)。该仪器能提供焊接参数的自适应反馈控制,把它们保持在预定的范围内。对于不良的焊接消耗材料,要发现它在焊接电弧中引起的化学方面的变异是较困难的。由于电弧温度极高,故必须采用遥感方法——前置摄影。作为 CERL 的焊接质量 The United States Army Engineering Research Laboratory (CERL) and the University of Illinois Radio Laboratory have developed a Welding Quality Monitor (WQM) that monitors welding process parameters and provides continuous images or printouts. The instrument can provide adaptive feedback control of welding parameters, keep them within the predetermined range. For poor welding consumables, it is more difficult to find out the chemical variations it causes in the welding arc. As the arc temperature is very high, so must use the remote sensing method - front photography. Welding quality as CERL
