Description

Technical Field

[0001] The present invention relates to the technical field of pipeline welding, in particular to a pipeline welding tracking mobile device. Background Art

[0002] Pipeline welding is a process of connecting pipe components by heating, pressurizing, or both, to form atomic bonds between pipes and pipe fittings. It is commonly used in the construction of pipeline systems such as oil, natural gas, water supply and drainage. The welding method such as argon arc welding, arc welding, and submerged arc welding should be selected according to the pipe material (such as carbon steel, stainless steel), pipe diameter, and wall thickness. Before welding, the interface must be cleaned and the assembly must be calibrated. During welding, the molten pool temperature and welding gun angle must be controlled to ensure a uniform weld.

[0003] In the actual operation of current pipeline welding operations, there are generally two typical welding scenarios, namely straight seam welding and circular seam welding. Regardless of whether straight seam welding or circular seam welding is performed, in order to ensure the accuracy and quality of the welding process, the operator will use a pipeline welding tracking mobile device to assist in completing the welding operation. The welding tracking mobile device controls the movement of the welding gun through a laser positioning device in conjunction with a mobile device. However, different tracking mobile devices are required in the process of straight seam welding and circular seam welding. When facing different welding methods, different welding tracking mobile devices need to be switched, which brings many inconveniences to the welding construction.

[0004] For this purpose, we propose a pipeline welding tracking mobile device. Summary of the Invention
