Abstract

The invention discloses a thick plate robot welding system and a multilayer multiple-pass weld real-time tracking and planning method. The thick plate robot welding system comprises a robot, a laser structure optical sensor, a welding system and a control system. The laser structure optical sensor comprises a main system, an optical system, a clamping system and a cooling system. In the welding process, images containing weld groove feature information can be obtained in real time and transmitted to the control system; the control system obtains the groove information from the images and controls the robot to constantly correct the position of a welding gun in the welding system; meanwhile, the control system adjusts a weld pass track and welding parameters so that multilayer multiple-pass real-time planning can be achieved, and labor efficiency and production quality can be improved.

Description

technical field [0001] The invention relates to the technical field of intelligent control of welding robots, in particular to a thick plate robot MAG welding system and a method for real-time tracking and planning of multi-layer and multi-pass weld seams. Background technique [0002] With the rapid development of heavy industrial fields such as road traffic, ocean engineering, and special ships, the demand for welding of large and thick plates in my country is also increasing. In the welding of large and thick plates, multi-layer multi-pass welding is one of the commonly used welding methods. At present, manual welding is mostly used in practical applications, which has high labor intensity and harsh working environment. Therefore, there is an urgent need for an automated and intelligent welding method that can replace manpower with robots. However, the main problems of using robots for multi-layer and multi-pass welding of thick plates at present are: as the number of we...
