Optimization and Improvement of Manufacturing Process for Large Diameter Irregular Tee Elbows
In order to ensure the manufacturing quality of special-shaped tee elbows,this article takes mine production work as an example,proposes the characteristics of large-diameter special-shaped tee elbows,analyzes the manufacturing process defects of special-shaped tee elbows,and provides optimization strategies for the manufacturing process of special-shaped tee elbows.Before welding,the groove and its vicinity are thoroughly cleaned,and surface oxide layers and pollutants are removed through pre-treatment methods such as sandblasting and polishing.During the welding process,adjust the welding speed and current according to the position and requirements of the weld seam,and use protective gas to effectively protect the welding area.Through the above optimization measures,the manufacturing quality and efficiency of large-diameter irregular three-way elbows have been further improved,and construction costs and risks have been effectively controlled.
