How do I weld something to a specific place on the player?

I have here my weld script but It doesn't weld the part to the specific place I want it to. What could I add to my code to make this work?

game.Players.PlayerAdded:Connect(function(Player) -- Player
    Player.CharacterAdded:Connect(function(Char() -- Character
        local Head = Char.Head -- Character's Body Part
        local Part = game.Workspace.Part -- Directory To Part To Weld
        local Weld = Instance.new('Weld', Head) -- Create Weld
        Weld.Part1 = Part
        Weld.Part0 = Head
    end)
end) -- End
