Embodiment Construction

[0038] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0039] This embodiment provides a vertical butt welding method for thick plates, which is used for vertical butt welding of thick plates. In this embodiment, the thick plate is a workpiece to be welded with a thickness of 10mm-60mm, and the vertical butt joint of the thick plate is such that the angle between the workpiece to be welded and the horizontal plane is greater than 15° and less than or equal to 90°. The vertical butt welding method of thick plate is as follows: figure 1 shown, including the following steps:

[0040] S10, using a positioning tool to perform vertical butt joint positioning of the workpiece to be welded.

[0041] The workpiece to be welded is vertically docked and positioned by the positioning tool. Specifically, the positioning tool includes a first positioning tool and a...

Abstract

The invention relates to the technical field of welding, and discloses a thick plate vertical butt joint welding method, and is used for butt joint of the thick plates to carry out welding operation.The method comprises the following steps of S10, carrying out vertical butt joint positioning on a workpiece to be welded by adopting a positioning tool; S20, the carbon dioxide automatic welding equipment is used for detecting the size parameters of the workpiece to be welded and the welding seam groove; S30, the carbon dioxide automatic welding equipment automatically matches the corresponding vertical butt joint welding parameters according to the detected welding workpiece and the size parameters of the welding seam groove in the step S20; S40, and the automatic carbon dioxide welding equipment is used for welding a welding seam of the workpiece to be welded through a carbon dioxide flux-cored wire. The thick plate vertical butt joint welding method comprises the steps of vertical buttjoint welding parameters, the carbon dioxide automatic welding equipment is used for welding a welding seam of the welding workpiece through a carbon dioxide flux-cored wire, the automatic degree ishigh, the welding seam is uniformly formed, and the quality of the welding seam and the strength of the welding seam are effectively improved.
