As shown in the figure, the height of the boss is 3 mm; can a 5-mm radius fillet be created?

It’s very easy. Has anyone told you that you’re a complete R5? It can be a 90-degree arc; can’t it also be 60 degrees or 40 degrees?

R5 is not a fixed value; its value cannot be determined after welding, while all other dimensions can be guaranteed. This structure is a common type used in heat exchangers and is a proven design.

Please refer to Appendix G, page 142 of GB151-1999

Actually, it’s just an approximate indication; no matter how many angles are specified, it still doesn’t give a clear picture, and the situation on site is completely different
