Welding point position adjusting system and method

The invention discloses a welding point position adjusting system and method, and belongs to the technical field of welding. The system comprises a first sensor, a second sensor, a master control system and an adjusting device. The first sensor is used for measuring the first offset of a first to-be-welded steel pipe, and the second sensor is used for measuring the second offset of a second to-be-welded steel pipe. The master control system is used for receiving and processing the first offset and the second offset, obtaining the offset of the contact point of the first to-be-welded steel pipeand the second to-be-welded steel pipe and sending an adjusting instruction to the adjusting device according to the offset of the contact point. The adjusting device is connected with a welding device and used for making the welding device aligned with the deflected contact point according to the adjusting instruction. By means of the provided welding point position adjusting system and method,the welding point position
