The invention relates to a steel pipeline friction-welding device. A programmable logic controller (PLC) device is respectively connected with an oil cylinder 1, an oil cylinder 4, an oil cylinder 6, an oil cylinder 8, an oil cylinder 13, an oil cylinder 22 and an oil cylinder 15 through a magnetic valve. The oil cylinder 1 is connected with a trolley, a rail is arranged under the trolley, the oil cylinder 4 is connected with an engine base plate, the oil cylinder 6 is connected with a clamp 7, and the clamp 7 is connected with a clamp base. The oil cylinder 8, a friction wheel and the oil cylinder 13 are connected with a movable clamping frame, the movable clamping frame is connected with the oil cylinder 15, and the oil cylinder 22 is connected with a fixed clamping frame. The fixed clamping frame 20 is connected with a clamp 21, the trolley 3 is installed on the engine base plate, and the movable clamping frame is connected with an upset forging vertical seat through the oil cylinder 13. The PLC device is connected with a pressure sensor, a temperature sensor and a power device. The power device is connected with the clamp 7. By means of the steel pipeline friction-welding device, the fact that weld joint strength is equal to strength of a matrix material in respect of welding quality can be achieve, welding efficiency is high, the quality is stable, and consistency is good.
Description
technical field [0001] The invention relates to a welding operation device used at the laying site of steel pipelines. In particular, it relates to friction welding equipment for steel pipelines. Background technique [0002] At present, when steel pipes are laid both at home and abroad, the butt joint of steel pipes all adopts the fusion welding construction method that the steel pipes are first matched and then arc welded. However, this method has poor welding quality. Compared with traditional fusion welding, friction welding has high-quality welded joints—it can reach the strength of the weld seam and the base material, and has high welding efficiency, stable quality, and good consistency. But so far, due to the particularity of the steel pipeline laying site, friction welding has not been applied. The length of the steel pipe on the laying site is generally 6 meters to 12 meters. Due to the limitations of the site conditions, it is difficult to make such a steel pipe...
