Description

Copper products are used in a variety of industrial applications like heat sinks, electrical components, etc. The specific parts are originally manufactured from copper raw material, which the process will form into long tubes or wires having various kinds of different cross sections. The process usually generates several hundreds of meters of this wire, which is wound on a big drum. The drum is eventually sold to the manufacturer of the electric components, for example. However, defects can also occur in the manufacturing process. The defects usually take the form of delaminations, and because of the fast drawing speeds of the tube or wire, the delaminations can be several meters long. Another type of defect that forms in the product is a small air bubble. If heat is applied to the product, the bubble may burst open leaving a hole in the surface.
