I understand that a post made of two studs has better strength than a "real" post with the same dimensions. But how do you best assemble the studs?

Screw, nail?
Toe-nail or straight through?
Or does it not matter at all?

The times I have seen a carpenter join a post, they have just nailed or screwed the studs straight up and down.

Depends on what you're going to use it for. In most cases, I usually glue and clamp them together, even with treated wood.

They will carry a glulam beam which in turn will support a standing seam metal roof.
 
Glue with PU glue and fasten it with a screw. Over time, it is the glue that holds it together.
 
There are also glulam posts. If you want a shape-stable post.
 
Without glue, a massive post is better.
If you use PU glue, apply glue on one piece and moisten the other; if you have plenty of clamps, use them or screw relatively closely. PU glue requires high pressure as it tends to expand.

PU - is it polyurethane?

Sounds reasonable as the prototype with several writes. To get multiple parts to cooperate, it's necessary to manage shear forces between the parts. If you don't, you'll have parts acting independently. Compare this to a plank between two supports. Place a milk carton in the middle, and it bends down. Add another plank and repeat the same thing. The deflection is almost the same. Now try using three screws so the planks can't slide between each other. Probably no significant deflection.

I usually use two pieces of 45x195 with a 45x95 on edge in between. This forms an I-profile. I haven’t calculated what such a column can handle in terms of load, but it’s substantial. Suitable for carports, decks, etc.

One very important thing with all column/beam constructions is that the supports are properly executed. Here, you want to distribute the load evenly across the entire column's cross-section so that you don't get stress concentrations that risk crushing the column's end.

Another thing that's good to consider is trying to make the column bear the load without surrounding building parts having to bend down first. I usually use a jack to lift the beam properly and almost lift the load a little before I install the columns.
 
Ok, I get your point. In this case, the posts will be covered with panel boards, so any screws will not be visible. My basic idea was to save a few kronor on the lumber cost, but since it turns out that there's only a ten kronor difference between two meters of 45x95 and one meter of 95x95, the savings are probably offset by the cost of screws and glue.

But now at least I know how it all fits together :-)

Does it work to assemble 2 45x95 (one a bit longer and one a bit shorter that the support can rest on) when building a deck? Large deck!
This way, you avoid buying heavy 95x95 posts.
 
That 95x95 is heavy can't really be a reason, can it? 2 pieces of 45x95 weigh pretty much the same...

Okay, but there are more advantages than just making it easier to handle studs.
Not least with having the bearers "resting" before screwing...

That's how I always do it.

Go for it!

Additionally, there is less risk of cracks in a glued post.

It gets better :-)
