Laser tracking type angle welding system and method for large curved plate

Abstract

The invention relates to a laser tracking type angle welding system and method for a large curved plate. The system comprises a laser tracking system, a welding parameter database, a data processing module and a welding adjusting module, wherein the laser tracking system is used for outputting real-time weld joint track data, the welding parameter database is used for storing welding parameter selecting data, the data processing module is used for retrieving corresponding welding parameter selecting data according to the real-time weld joint track data and outputting the corresponding weldingparameter selecting data to the welding adjusting module, and the welding adjusting module is used for adjusting a welding gun according to the welding parameters. The method comprises the steps thata weld joint is tracked in the welding process, and the real-time weld joint track data is output; the corresponding welding parameter selecting data is retrieved according to the real-time weld jointtrack data and is output to the welding adjustment module; the welding gun is adjusted according to the welding parameters of the welding parameter selecting data; and each piece of the welding parameter selecting data comprises a welding parameter part and weld joint track information corresponding to the welding parameter part. The system and method have the beneficial effects that the weldingparameters can be adjusted according to real-time weld joint data in the welding process, and therefore the welding errors can be conveniently reduced.

Description

technical field [0001] The invention belongs to the field of welding automation, in particular to a laser tracking system and method for fillet welding of large curved panels. Background technique [0002] Shipbuilding includes parts processing, parts group, segmented assembly and welding, segmented closure, hull closure and many other technological links. Among them, parts processing, component group, and component painting have realized automatic or semi-automatic construction and processing, but as hull construction The core link in the process - segmental welding, especially curved surface segmental welding, there is still no sufficient and effective automation / semi-automation technology solution. [0003] Most of the technologies for curved surface welding in the prior art are aimed at the curved panels that are easy to move, and it is difficult to weld large curved panels that are inconvenient to move; one of the technical solutions is to use the manual operation simul...

Problems solved by technology

The disadvantage of this welding method is that firstly, manual operation is required for simulation, which is inefficient, and secondly, the movement trajectory of the automatic welding robot is too rigid, and the error existing in the welding seam cannot be adjusted in real time, and the welding effect is not good.
