| Abstract: | Aiming at the CO2 pre-welding of the Longitudinal Welded pipe, taking the laser as the initiative light source, a visual sensing for automatic weld tracking system is developed. In order to eliminate the disturbance of spatter in weld image of laser marking, simulation circuit is applied in the process where video signal is magnified and trimmed, at the same time ,the program processing is utilized in one-chip computer. As a result, the deviation is estimated correctly and the weld automatic tracking is realized. Experiment results show that the response cycle of the system is no more than 80ms, and the tracking precision is less than ±0.5mm. |
