| Abstract: | Based on the arc light spectrum theory, the auxiliary lighting source and composite filtering techniques were used to solve the negative factors such as poor resolution and radiation disturbance by weld pool. The effect of spectral filter and auxiliary lighting source on the image quality was experimentally studied. The results show that compared with conventional image acquisition method, this system can acquire the image with high resolution and can be used in real-time monitoring during welding process. |
