Generative cold welding methods and generative cold welding device

摘要

The method involves providing metal particles (1) as a first welding pair through particle feeding unit (11). The metal particles are accelerated at speed of 100 m/s through particle accelerating unit (12). The accelerated metal particle is aligned onto welding point on metal substrate (1',5,5') forming second weld pair. The accelerated metal particles are made to impinge to welding point on substrate, for bringing surface atoms of metal particles and metal substrate at atomic spacing to form metal bond that bonds metal particles on welded joint (1') with metal substrates. An independent claim is included for cold welding device for joining metallic joining pair.
