economical and proper way to weld these parts
(OP)
So I am designing a manifold, and I know there are multiple ways to weld a barb to a pipe, however the barb needs to be on a 30-45 degree angle (undecided) so reduce pressure drop, now, I will machine the barb, but would it be best to just drop the barb into an angled hole in the pipe? or cut a wedge shape on the end of the barb and mating pipe and weld or what?

Mounting the manifold into a mill and drilling angled holes is no big deal.
And if the barbs fit against the OD surface then a couple of tack welds is all that it takes.

Ed Stainless has given you the best advice , Hold the end of the barb at an angle in a machine vice, then cut the contour with a milling cutter to achieve what he said. The drilling is easy.

Cut the ends of the tubes at an angle, then use a cutter that matches the OD of the manifold to put a radius into the angled end. These will fit on the OD surface.
Drill your holes in the manifold to match the ID of the barbs.
I presume that the barbs have thinner walls than the manifold. This way you can get full penetration welds.

So would you drill straight holes into the pipe instead of angles holes? matching the holes of the ID of the barbs while the barbs are angle cut will be an oval hole on the pipe then?
RE: economical and proper way to weld these parts
Yes the holes in the main tube will be cut at an angle and will generate an oval hole. You can do this by first clamping the manifold in a vice , pilot drilling small holes at the correct locations , then clamping the manifold in a sine vise at the correct angle , use an end mill of the correct diameter to bore the holes at an angle. your correctly shaped barb will sit on top of this hole and match the shape of the outside of the main tube.

I guess my explanation was not quite clear, the pilot holes I described would be drilled in at 90* to the pipe surface at the correct positions .
These holes are only there to avoid material build up in the dead center of the end mill when milling at an angle into the tube.

Correct . You can use the method I proposed, or go talk to your machine shop, but the end result should be the same.
