Problems solved by technology
Due to the internal stress generated during the welding process, the weldment is deformed, which seriously affects the project quality, project progress and welding performance; however, the way of mechanical pressure to suppress welding deformation is cumbersome and inflexible, and different products require different fixtures , the economic investment is large, and the effect is sometimes not obvious, and the cause of the welding deformation has not been found out fundamentally, and the welding deformation has not been solved
At the same time, the existing methods of mechanical pressure to suppress welding deformation all require cable connection. In the actual manufacturing process, the cable will affect the welding of the manipulator.

The invention provides a wireless closed-loop control method, device and storage medium for suppressing welding deformation of medium and thick plates based on laser. The method includes: emitting laser illumination; receiving the emitted effective laser illumination; processing the received effective laser illumination to obtain the deformation amount of the medium and thick plate, and determining output parameters; receiving the determined output parameters, And adjust the deformation amount of the medium and thick plate according to the output parameter. The invention uses laser emission and reception technology to monitor the welding deformation of medium and thick plates in real time, and transmits the monitoring data to the manipulator control box in a wireless manner. parameters to suppress welding deformation, form a closed-loop control, and then fundamentally suppress welding deformation. At the same time, the interference effect of cables on the actual welding of the manipulator is avoided.
Description
technical field [0001] The present invention relates to the technical field of welding, in particular, to a wireless closed-loop control method, device and storage medium for suppressing welding deformation of medium and thick plates based on laser. Background technique [0002] With the advancement of science and technology and the development of industry, various welding machinery and welding methods are changing with each passing day. However, during the construction process, since the weldment is a whole, if the weldment is partially heated and cooled during the welding process, then The degree of thermal expansion and contraction of the metal in each part of the welded joint is also different. The overall factor of the weldment determines that each part is interconnected and restricted, and cannot be freely extended and shortened, so it is inevitable that strain and deformation will occur during the welding process. Due to the internal stress generated in the welding p...
