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.
