There is a shouldered rod bit that looks like that, or you could make it. It gets brazed into the tube end, and then the thingie gets brazed to the seat tube. That's one way anyway.

The second way is to braze a manufactured plug to the top of the seat stay. The plugs are already finished with the shape designed in, but have the disadvantage of weighing more than the flat steel plate cap. Cinelli makes plugs of various shapes for different sized seat tubing.

For light duty frames you can use shot-in stays where the upper end is integrated with the seatpost clamp.
The classic method is good for light-med touring. There was a neat weight saving trick (shown by Peter White if I recall) using a reversed section of tubing (concave-out) cut form a scalloped end rather than a heavy investment cast plug. This example does it without the scalloped shape.
Heavy duty frames often extend the area of braze by using wrap-around plugs.
