union thin protruding surfaces

[calacc]

Hello, I'm having a problem in modeling a squadron valve body. the operation to be carried out is the union of two thin blend surfaces in order to obtain a single homogeneous surface. perhaps it is not very indicated the use of this command but having little experience I do not know other methods. I attach images by trusting in your support

I think the best method is to model in surface mode (without thickness), join the two entities (merge), add rounding (if there is) and after thickness.

Thank you for the advice max, I actually suspected I should have jumped immediately on the surfaces... However making a cut in intelligent extrusion and extruding up to the inner surface of the first subtle blend I managed to take a step forward. now for completeness should I "buke" the surface at the intersection (can you do????), add the fitting and we are

think if you modeled it full from the beginning how many less you would have had...

Yes, the one you used is one of the possible solutions.
Of course you can do, you can use the merge or trim according to the context (the trim is advisable in situations of greater complexity).
the merge I think is more suitable, with a function less you get the same result.

or as ozzy says, you can achieve it in solid mode and then sgusciarlo ... but I don't know if you have constant thickness throughout the context.

in fact, initially I had tried to shape it from the full and I had problems in the sguscio phase because of the thicknesses. I couldn't manage the conflicts between the features and so I decided to change the way.. .
As for the two trim commands and the merge can't select either of them because they are in gray, I don't know how to do it.. .

Now I think I'm here! instead of using thin protrusion I used the surface command creating the 2 surfaces one inside the other (fig 1). I have created a fitting surface between 2 (fig 2), I have joined two to two surfaces with the intermediate fitting and finally offset the desired thickness surfaces (fig 3)
