METHOD OF DIFFUSION WELDING OF METALS AND ALLOYS Russian patent published in 1999 - IPC

Abstract RU 2135337 C1

FIELD: mechanical engineering; aviation and space engineering; instrumentation; diffusion welding of homogeneous and heterogeneous metals and alloys in making of nonsplit structures. SUBSTANCE: first surfaces of workpieces to be welded are machined to provided high degree of roughness. Then blank are heated to polymorphous pre-transformation temperatures using pulsed high energy current action. EFFECT: simplified welding process, reduced labour input and power consumption, enlarged nomenclature of welded connections. 2 cl
