Making welds with rotation?

I have this sphere like ball made with parts that are rotated and cframed. Is it possible to weld them all together without removing its rotation?

all=Workspace.Model:getChildren()
for a=1,#all do
	if all[a]:IsA("BasePart") and all[a].Name=="Holder" then
		holder=all[a]
	end
end
for a=1,#all do
	if all[a]:IsA("BasePart") and all[a].Name~="Holder" then
		local weld=Instance.new("Weld",all[a])
		weld.C0=all[a].CFrame--+all[a].CFrame.Angles
		weld.Part0=all[a]
		weld.C1=holder.CFrame
		weld.Part1=holder--+holder.CFrame.Angles
	end
end
for a=1,#all do
	if all[a]:IsA("BasePart") then
		all[a].Anchored=false
	end
end
