Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe welding devices, in particular to a steel pipe welding device with a grinding function. Background Art

[0002] The steel pipe welding device is a device specially used for connecting steel pipes. It is widely used in various industries, such as oil and gas pipelines, building structures, shipbuilding, automobile manufacturing, aerospace, chemical equipment and other fields. It fixes two steel pipes on the welding fixture and welds the two steel pipes by welding.

[0003] Common steel pipe welding equipment needs to move the steel pipe from the welding area to the grinding area after welding, which reduces the overall production speed. Grinding can help check the welding quality. After the steel pipe is polished, defects in the weld may be found, such as weld nodules, depressions or lack of fusion, which may require rework due to welding quality issues.

[0004] Therefore, the above-mentioned steel pipe welding device lacks a grinding function. After welding, the steel pipe needs to be moved from the welding area to the grinding area, which reduces the overall production speed. At the same time, after the steel pipe is polished, defects in the weld may be found, such as weld nodules, depressions or unfusion, which requires rework. A steel pipe welding device with a grinding function can be designed. The two steel pipes are welded by a welding mechanism. After the welding work is completed, the steel pipes do not need to be disassembled. The connection between the two steel pipes can be polished by the grinding mechanism, eliminating the step of moving the steel pipe from the welding area to the grinding area, thereby speeding up the overall production speed. Grinding can also help check the welding quality, timely discover and correct defects in the weld, reduce rework caused by welding quality problems, and ensure the flatness and strength of the weld to solve the above problems.
