What do pressure vessel riveters mainly do? Tell me the general content. I want to tell the interviewers.

The riveting of pressure vessels mainly involves sealing and riveting. This interface involves sealing as long as it is a container. For containers that bear pressure, the requirements for sealing are even more stringent. Gluing refers to applying sealant. The fitting surface between the parts achieves a sealing effect and withstands a certain fatigue strength. The surface is smooth and the weight is light. The labor intensity is also small, which almost overcomes the shortcomings of riveting. In order to achieve a sealing effect of the sealed container and have a certain connection strength, it is adopted. The glue riveting hybrid connection method is divided into the first type, in-seam sealing riveting, which first places the sealing material between the connecting parts to block the gap after the parts are connected to achieve a sealing effect. The second type, surface sealing riveting, is after the parts are riveted in the structure. The inner or outer surface is coated with one or more layers of sealing material to achieve a sealing effect. The last one is hybrid sealing riveting, which is a combination of the first and second types. When parts with high structural strength requirements can also be used with dry fit bolts and belts. Of course, the gasket connection also belongs to the category of riveting
