Cross-section of cold welding – before and after the weld. Cold welding or contact welding is a solid-state welding process in which joining takes place without fusion or heating at the interface of the two parts to be welded. Unlike in fusion welding, no liquid or molten phase is present in the joint. Cold welding was first recognized as a ...

Overhead stick welding. Welding is a fabrication process that joins materials, usually metals or thermoplastics, primarily by using high temperature to melt the parts together and allow them to cool, causing fusion.
Cold metal transfer (CMT) is a welding method that is usually performed by a welding robot. The CMT machine detects a short circuit which sends a signal that retracts the welding filler material, giving the weld time to cool before each drop is placed. This leaves a smooth weld that is stronger than that of a hotter weld.
Using a high energy mill to favor plastic deformation required for cold welding and reduce the process times; Using a mixture of elemental and master alloy powders (the latter to reduce the activity of the element, since it is known that the activity in an alloy or a compound could be orders of magnitude less than in a pure metal)
In metallurgy, cold forming or cold working is any metalworking process in which metal is shaped below its recrystallization temperature, usually at the ambient temperature.. Such processes are contrasted with hot working techniques like hot rolling, forging, welding, etc. [1]: p.375 The same or similar terms are used in glassmaking for the equivalents; for example cut glass is made by "cold ...

Operation Condor was an attempt to weaken the Viet Minh artillery's assaults against the besieged French Union garrison of Dien Bien Phu. On April 22 1954, General Cogny insisted with his superior General Navarre to take a decision about Condor. General Navarre approved the mission on April 27 and it was launched on April 30. [1]
