[MW:20655] WPQ for SS to Inconel Welding

Dear all,

Plate thickness 14 mm
Plate material SA 240 TYPE 304L
Joint Single V groove joint
Can I qualify welder for SS and inconel ( for F-No) in the same joint?
Weld deposited thickness 7mm (for SS ) and 7mm (for inconel).
I have heard that SS cannot be welded on Inconel but vice versa is  possible i.e. Inconel on SS.
If yes how? And if answer is No then how?
Is there any metallurgical change involved in this?

Kindly help.
