Technical Vision System for Arc Welding Process Automatic Control Systems in Shipbuiding

摘要

The work reports development of the technical vision system (TVS), included into the metal structure arc welding process automatic control system in shipbuilding. Versions of construction and optimization of the sensor system (SS) of TVS and its main components - irradiation and television unit (ITU) and program and computer system are considered. TVS allows to control geometrical parameters of the butt of joined parts of various configurations and welded seam and also develops signals on control of matched movement of a torch with real line of a welded joint, adjustment of feed of welding components (wire, fluxes, gases) and arc welding parameters. The non-contact method of triangulation measurement, used in TVS, provides resolution of geometrical sizes in real time scale not lower than 50 μM.
