Abstract
A storage reel for copper coated iron welding electrode wire comprises a tubular core of plywood having opposite ends and flanges of plywood at the opposite ends. A vapor barrier layer preferably having outer layers of aluminum foil and an intermediate layer of paper is bonded to the axially inner surfaces of the flanges to provide a barrier against the migration of moisture and other vapor contaminate in the wood material to the welding electrode wire wound on the reel. A method of constructing the reel is also disclosed.
