Multi-gauge strip

摘要

An improved method and apparatus for the production of multi-gauge strip is disclosed wherein the multi-gauge strip comprises a first strip of metal having a first thickness and extending longitudinally for a given length. A second strip of metal has a second thickness, is narrower in width than the first strip, and coextends longitudinally with the first strip of metal. The first and second strips of metal are intimately bonded in direct metal-to-metal contact without the use of a welding or brazing material. The multi-gauge strip has a first portion extending the given length with a third thickness substantially equal to the sum of the first and second thicknesses and a second portion of substantially constant width extending the given length having a fourth thickness substantially equal to the first thickness.
