does anyone know how to weld a model to a player, and then make that part face forward?

function weldPartToCharacter(char)
	local root = char:WaitForChild("HumanoidRootPart")
	
	--new part to be created
	local part = Instance.new("Part")
	part.Anchored = false
	part.CanCollide = false
	part.Parent = char

	 --creates a weld with the humanoid root part and the newly created part
	local weld = Instance.new("Weld")
	weld.Part0 = root
	weld.Part1 = part

	--[[The CFrame difference of the part. 1 unit away on the x axis, 90 rotation on the y axis.
	The axes might be a bit different whenever welding when compared to the global ones]]-- 
	weldd.C1 = CFrame.new(1, 0, 0) * CFrame.Angles(0, math.rad(90), 0)
