How do I weld parts to the head like eyes with r15?

local Chosen = Players:GetChildren()[math.random(1,#Players:GetChildren())] -- Shadow walker
if Chosen.Character and Chosen.Character:FindFirstChild('Pants') then
Chosen.Character.Pants:Destroy()
Chosen.Character.Shirt:Destroy()
for i,v in pairs(Chosen.Character:GetChildren()) do
    if v:IsA('Accoutrement') then
        v:Destroy()
    end
for _,v in pairs(Chosen.Character:GetChildren()) do
   if v:IsA("BasePart") then
      v.BrickColor = BrickColor.new("Really black")
   end
end
end
end
end)

How would I weld to parts to the head at the location as eyes? Thanks!
