Abstract
Aiming at the strict requirement for weld alignment tolerance in CO2 pre-welding of the longitudinal welded pipe, taking the laser as the initiative light-source, a visual sensing for automatic weld misalignment tracking system was studied. In order to eliminate the influence on laser stripe of spatter, groove reflection and arc light, the software based on VC++6.0 developing environment is applied in the process where image data was handled. Experiment results showed that the detection precision and sensitivity of the system meet the requirements for the practical production. The response cycle of the system is not more than 60 ms, and the tracking precision can reach ±0.2 mm.关键词
