Front Side Image Detectingand Processing of Keyhole Pubdle in Plasma Arc Welding of Aluminum Alloys

Wang Huijun Wang Qilong Liu Zhonghua (Harbin Institute of Technology)  
A narrow-band composite filtering system is developed to acquire clear image of keyhole puddle in plasma arc welding of aluminum alloy. The geometric size of visible keyhole, such as keyhole width and keyhole area are detected with Gauss fillter, Prewitt edge detecting and image offsetting edge detecting.
