摘要
所研制的CCD图像传感器系统 ,通过采用比色测温的方法 ,实现了对焊接温度场图像的实时采集与处理。以焊接电流为控制量 ,研制了薄板钨极氩弧焊 (TIG)背面温度场等温线宽度闭环控制系统 ,实现了对焊缝背面熔宽和熔透的控制。大量的焊接工艺试验证明本系统在焊接生产中具有重要的应用价值。
In the developed CCD image sensor system,real-time collecting and disposing the welding temperature field image is realized by means of using the method of colorimetric temperature measure.A closed-loop control system with welding current as control parameter is founded to control the width of isothermal line of back-side welding temperature field in TIG welding of thin plate.The control of penetration and width of back side weld is achieved.As welding experiments suggested,the system have important application value .in welding production.
