coldweld
Coldwelding is a solid-state welding process where two clean metal surfaces are joined together under pressure without the application of heat or filler material. This occurs when the surfaces are brought into such close contact that their atoms bond across the interface. The process relies on removing or preventing the formation of oxide layers or other contaminants that would inhibit direct metal-to-metal contact.
For coldwelding to be successful, the materials being joined must be ductile. The pressure applied forces the
Common applications for coldwelding include joining dissimilar metals, particularly soft, ductile metals like aluminum and copper,
