Abstract

The invention discloses an automatic welding system and method based on a moveable thick plate. The automatic welding system comprises an industrial robot, a welding machine, a welding gun, a touch screen, an industrial personal computer, a laser sensor, a welding gun cleaner, a wire feeder, a wire feeding plate and the like. A filling amount model and a welding process data card are used as references to form a set of welding expert database system; through acquisition of information of welding plates and assembly condition, the welding seam layer passage distribution is planned, and the welding process parameter of each layer passage is calculated. The laser sensing technology is adopted to acquire the position data of the starting point and the terminal point of a welding seam; according to the welding seam layer passage distribution condition, the position data of the starting point and the terminal point of the welding seam is calculated. Therefore, workpiece difference auto-adaptation thick plate beveling multi-layer multi-passage automatic welding is realized.

Description

technical field [0001] The invention relates to the technical field of intelligent control of welding robots for thick plates, in particular to an automatic welding system and welding method based on movable thick plates. Background technique [0002] With the rapid development of heavy industrial fields such as ships, road traffic, and ocean engineering, the demand for thick plate welding in my country is also increasing. In thick plate welding, multi-layer multi-pass is one of the commonly used welding methods. At present, the degree of automation in domestic thick plate welding is low, and most of the welding work is done manually, resulting in insufficient quality stability and insufficient production capacity. Due to the advantages of strong versatility and reliable operation of welding robots, the use of robot welding has become the main symbol of the modernization of welding automation technology. [0003] At present, because the welding path and welding parameters ...
