Embodiment Construction

[0044] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with specific embodiments.

[0045] The present invention provides the control method specifically as figure 1 shown, and includes the following steps:

[0046] Move the welding unit, identify the pipe joint position and judge whether the welding unit is located directly above the pipe joint position, if not, continue to move the welding unit until the welding unit is directly above the pipe joint position, if so;

[0047] Initialize the welding unit and determine the initial position of the welding unit, scan the contour of the pipe joint position, and obtain the pre-scanning data;

[0048] Determine the position of the welding torch according to the pre-scanning data, plan the welding parameters and welding path;

[0049] The welding unit is controlled according to the positi...

Abstract

The invention discloses an automatic welding control method. By moving the welding unit and recognizing the butt joint position of the pipeline, the welding unit is located over the butt joint position of the pipeline, and the labor cost is reduced through the automatic control mode. Initializing the welding unit, obtaining the initial position of the welding unit, scanning the butt joint position of the pipeline, obtaining scanning data, obtaining the position of a welding gun through the scanning data, planning welding parameters and a welding path, and controlling the welding unit to carry out welding operation. The position of the welding gun is obtained through calculation of the sensor, the welding parameters and the welding path are automatically planned through the deep learning network, automation of the whole welding process is achieved, the labor cost is greatly reduced, precision errors caused by manual operation are eliminated, and the welding precision is improved.

Description

technical field [0001] The invention relates to the field of welding, in particular to an automatic welding control method. Background technique [0002] With the advancement of social technology and the sharp increase in human demand for various resources, long-distance pipelines are developing in the direction of large-diameter, long-distance, high-pressure, and high-grade steel. Traditional manual welding and semi-automatic welding have been difficult to meet the requirements of pipeline welding. , The welding technology is also developing in the direction of automatic welding, using multi-layer and multi-pass welding, first using the internal welding machine for bottom welding, and then using the external welding machine for heat welding, filling welding, and cover welding. [0003] At present, external welding adopts manual control remote control, controls the welding machine to perform single-layer welding on the groove, obtains the initial position of each unit before...
