Welding issue with a DN25 small connection (flush water inlet) of an evaporation separator

The cylinder of an evaporation separator I designed requires S30403 material with a thickness of 24 mm; the upper head of the separator has a wash water inlet pipe with a DN25 diameter, and the maximum wall thickness there is only 4.5 mm. What should be done in this situation? Should it be a local forging, or the addition of a reinforcement ring, or a tube blank? What do everyone else do?
It’s not necessary to reinforce when taking over a DN25 pipe. Welding can be carried out directly with a groove.
But welding by directly making a groove like this would likely cause the fitting to be welded through, right? The cylinder is so thick while the nozzle is so thin. We require full penetration welding.
The real hair system belongs to a negative pressure system, allowing for direct welding.
One and a half cobelens need to be added. Then weld the DN25 pipe.

Direct welding will do. If you’re worried, add a tube socket.
Thank you all, I’ve added the pipe socket.
Suggestion: Just speak up； Welding is performed using TIG welding
