Abstract：Welding equipment is a kind of mechanical equipment, assembly in order to reduce the time consumed in the auxiliary and subsequent additional work, in order to improve the welding efficiency and quality, plays an important role in the welding as the main process in the manufacturing process. This graduation project has mainly analyzed the working principle of the ring welding machine, and studied the whole layout and structure of the device. After fully considering several design ideas, the best scheme is selected. Based on this, the power system, transmission system, supporting system and connecting device of the reaction tank are designed. Finally, the three-dimensional modeling is completed. Its strength meet the design conditions and components, reasonable arrangement of the space, simple structure, can be widely used in all kinds of welding machinery and equipment to improve labor productivity, its reasonable design and wide application of the smooth realization of welding process is of great practical significance.
