In order to meet the needs of different industries for steel pipe quality and specifications, steel pipe manufacturing technology has been continuously improved. Among them, straight seam steel pipe welding technology has gradually become mainstream due to its high efficiency, flexibility, and reliability. The research and development and manufacturing of straight seam steel pipe welding equipment have undergone a transformation from simple to complex, and from manual to automated. Early straight seam steel pipe welding equipment was mostly manually operated, resulting in low welding quality and production efficiency. With the development of automation technology, modern straight seam steel pipe welding equipment has achieved a high degree of automation and intelligence, including automatic feeding, clamping, positioning, welding, and testing of steel pipes.

[0003] The existing straight seam steel pipe welding device usually adopts the method of moving the steel pipe during use to continuously weld the straight seam on the steel pipe. However, if the steel pipe rotates slightly during the movement, it will affect the accuracy and quality of the welding, which is inconvenient to use. Therefore, in view of the above situation, there is an urgent need to develop a straight seam steel pipe welding device to overcome the shortcomings in current practical applications.
