Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, in particular to a cylinder welding device for magnetic resonance equipment. Background Art

[0002] In the manufacturing process of magnetic resonance imaging (MRI) equipment, the cylinder is a critical component, and its welding quality directly impacts the overall performance and stability of the device. Traditional welding processes often rely on manual welding or simple automated welding equipment, making it difficult to consistently control welding quality. Manual welding relies heavily on the welder's skill level, and problems such as uneven welds and weld deformation can easily occur during the welding process, affecting the cylinder's sealing and service life. While simple automated welding equipment can improve production efficiency, it also struggles to ensure consistent welding quality due to its lack of sophisticated control and adjustment mechanisms.

[0003] Secondly, traditional welding processes suffer from low production efficiency. Manual welding requires significant manpower and time, while less automated welding equipment cannot achieve efficient and continuous welding operations. This not only increases production costs but also limits the large-scale production of MRI equipment.

[0004] Furthermore, traditional welding processes present a harsh working environment. The smoke, harmful gases, and noise generated during welding pose a threat to welders' health. Long-term exposure to such conditions can lead to welders developing occupational diseases such as pneumoconiosis and hearing loss.

[0005] Therefore, in order to improve the welding quality and production efficiency of cylinders used in magnetic resonance equipment, improve the working environment, and reduce maintenance costs, it is necessary to develop a new cylinder welding process and device. Summary of the Invention
