In 2009 the European Space Agency published a peer-reviewed paper detailing why cold welding is a significant issue that spacecraft designers need to carefully consider.

The chemical inertness produced by a vacuum is also useful for electron beam welding, cold welding, vacuum packing and distillation, metallurgy, and process purging.

Combined with other nano-and microfabrication technologies, cold welding is anticipated to have potential applications in the future bottom-up assembly of metallic one-dimensional nanostructures.
14.
Alternatively, cold welding between two metal surfaces could also transfer low-dimensional nanostructured metal without heating ( especially for critical sizes less than ~ 10 nm ),.

The conclusions of this appropriately titled study can be found on page 25 of " Assessment of Cold Welding between Separable Contact Surfaces due to Impact and Fretting under Vacuum ".
16.
The cold welding approach has the advantage of reducing surface contact contamination or defect due to no heating process, which is a main problem in the latest development and fabrication of organic electronic devices as well as novel solar cells.
17.
The process and contact can be compared to cold welding or friction welding, because cold welding is not truly cold and the fusing points exhibit an increase in temperature and energy density derived from applied pressure and plastic deformation in the contact zone.

Recently scientists discovered that single-crystalline ultrathin gold nanowires with diameters ~ 3 10 nm can be " cold-welded " together within seconds by mechanical contact alone, and under remarkably low applied pressures ( unlike macro-and micro-scale cold welding process ).
20.
The process is commonly used for welding dissimilar materials, such as the welding of aluminum with steel in ship hulls or compound plates . magnetic pulse welding, co-extrusion welding, cold welding, diffusion bonding, exothermic welding, high frequency welding, hot pressure welding, induction welding, and roll welding.
