A multi-gauge composite metal strip is produced from a plurality of individual metal strips of different thicknesses. The individual strips are heated, passed through an oxide reducing atmosphere and are then directed between a pair of work rolls with their adjacent edges arranged in a mutually overlapping relationship. The rolling action effects a reduction in the thickness of each strip while simultaneously effecting solid phase bonding of their overlapping edges. The resulting composite multi-gauge strip is subjected to tensile stresses which exceed the yield strength of the strip materials at the time and in the condition at which the composite strip exits from between the work rolls.
