[0004] Although the above-mentioned equipment can perform welding operations on pipelines, it is not convenient to accurately position the pipe joints when welding the pipelines. Moreover, the above-mentioned welding equipment can only perform a single welding operation, and it is not convenient to perform 360-degree repair welding on welding defects after welding is completed, which reduces the practical performance of the equipment. Therefore, an energy-saving and efficient welding positioning device is needed to solve the above-mentioned problems. Summary of the Invention
