Embodiment Construction

[0037] The application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain related inventions, rather than to limit the invention. It should also be noted that, for ease of description, only parts related to the invention are shown in the drawings.

[0038] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and embodiments.

[0039] As mentioned in the background art, most of the automatic welding robots currently used in China adopt a rail-type welding design, and the robot travels along the rails, which has achieved certain results. However, when the robot reaches the corresponding position, certain welding personnel...

Abstract

The present application discloses a control method and a control device for a welding process. The method determines the width and depth of the welding seam based on a laser image; obtains the deposition width and deposition height based on the deposition amount and welding parameters; establishes the welding seam The mapping relationship between the groove width and the welding seam groove depth and the deposition width and deposition height; the moving path of the welding torch is determined based on the mapping relationship. When the welding device reaches the corresponding position, the welding torch automatically moves to the position that needs to be welded, without the need for welding personnel to operate and control, the operation is simple, the accuracy is good and the efficiency is high.

Description

technical field [0001] The present invention generally relates to the technical field of welding control, in particular to a control method and a control device for a welding process. Background technique [0002] As an important production method closely related to the manufacturing industry, pipeline welding is facing unprecedented challenges in many aspects with the gradual deepening of the modernization of industrial production. New requirements are put forward for welding technology level and welding production mode, and it is urgent to improve welding. level of intelligence and automation. As an important aspect reflecting the level of welding automation technology, the pipeline weld automatic tracking system is playing an increasingly important role. At present, most of the automatic welding robots used in China adopt the guide rail welding design, and the robot travels along the guide rail, which has achieved certain results. However, when the robot reaches the cor...
