| Abstract: | Based on the heat-transfer theory and the law of the black-body radiation, the authors developed a mathematic model for identifying the temperature distribution across the back of weld-bead with CCD (Charge Coupled Devices) as the sensor. A program which processes the image picked by CCD was designed. The excellent consistency between the results of the calculation and measurements proves the correctness of the proposed method. Being of rather simple system construction and fast imagerecognition, the developed technique may be utilized to precisely control the welding quality in real--time. |
