MANUFACTURING METHOD OF LAMINATED CLAD WIRE ROD Russian patent published in 2015 - IPC B21C23/22 B23K20/04 

FIELD: metallurgy.

SUBSTANCE: surface of a base is pre-cleaned by an ultrasonic method, and then, it is subject to electrolyte-plasma treatment. Simultaneous supply of the base and a clad layer and assembly of a workpiece by sealing of a connection zone is performed. Heating and joint deformation of a laminated workpiece is performed in a rolling mode in a vertical pair of rolls with further drawing in a horizontal pair of rolls in a common deforming block at preliminary stepped heating to pre-rolling temperature within 0.7-0.8 of the melting temperature of the clad material. The workpiece is blown with a steam-and-air mixture at the inlet of the horizontal pair of rolls. Pre-rolling heating is performed in a non-corrosive medium. A rolling pair of rolls has a diameter of at least by 10% larger than the diameter of the rolls of the drawing pair.

EFFECT: method provides for obtaining of a strong connection of a base with a clad cover.
