Abstract: The design is divided into three parts, basic knowledge of welding structure, welding process and welding inspection. It contains nine chapters. The first and second chapter mainly introduce the knowledge of cylinders, the third and fourth chapter are about materials used in cylinders and cylinder production. The fifth, sixth and seventh chapter mainly introduce the whole process of welding production, welding materials, and welding technical inspection. The content of this part is the most important. Cylinder is the main auxiliary equipment of a boiler. It is used to allocate the boiler steam produced during the boiler running to each pipe. Cylinder is a pressure bearing equipment, and its pressure bearing capacity should be corresponding with the auxiliary boiler.
Key words: Cylinder ;Pressure vessel ;Pressure welding; assembly;
