Welding with a server event function, wtf am I doing?

game.ReplicatedStorage.RemoteEvent.OnServerEvent:Connect(function(player)
		if	player.Character.Humanoid.Health >= 100 then
		local anvil1 = Instance.new("Part")
		local anvil2 = Instance.new("Part")
		local anvilweld1 = Instance.new("Weld")
		anvilweld1.Part0 = anvil1
		anvilweld1.Part1 = anvil2
		anvilweld1.C0 = anvil1.CFrame
		anvilweld1.C0 = anvil2.CFrame
		anvilweld1.Parent = anvil2
		anvil2.CFrame = anvil1.CFrame * CFrame.new(5, 5, 5)
		anvil1.Parent = game.Workspace
		anvil2.Parent = game.Workspace
		anvil1.CFrame = player.Character.Head.CFrame * CFrame.new(0, 10, 0)
		anvil1.Velocity = Vector3.new(0, -50, 0)

Was trying to figure out how welding works in general, ended up having no clue what I did, but managed to weld anvil1 and 2 inside each other, but cant change the position of anvil2, if that's actually what I did. Need help figuring out how this actually works lol.
