Not To Rotate Around The Weld But The Part?

I'm welding my part to another part and I'd like to rotate it but using this

w.C1 = CFrame.new(0, 0, 3) * CFrame.Angles(0,1.5,0)

it's rotating around the part it's welded too and making it quite awkward, I was wondering if it's possible for me to just rotate the part using it's own position well keeping the weld?
