Thick plate vertical butt joint welding method

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.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a vertical butt welding method for thick plates. Background technique [0002] In the pre-loading and loading stages of the shipbuilding industry, carbon dioxide semi-automatic welding methods, simple carbon dioxide automatic welding methods or vertical gas-electric welding methods are generally used for vertical butt welds, among which carbon dioxide semi-automatic welding methods are affected by workers' skills and groove quality. , uneven weld formation and unstable welding quality; the vertical gas-electric welding method cannot be used during the welding process due to the heavy vertical gas-electric welding equipment, many cables, complicated operation, small space or obstacles; simple carbon dioxide automatic welding This method cannot realize the functions of automatic groove detection, matching parameters, automatic welding, etc., and there are many human interventions ...
