economical and proper way to weld these parts 2

[valmeidan]

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?

Thanks all for yout help...

The manifold diameter looks too small relative to the size of the branches. You have too much velocity in the pipe - increase the manifold diameter so that the velocity pressure is inconsequential compared to the static pressure in the manifold. Study your fluid dynamics before you try to tweak a manifold that will never work regardless of take-off angle.
