Unlike in fusion welding, no liquid or molten phase is present in the joint. Cold welding was first recognized as a ...
This is a list of welding processes, separated into their respective categories. The associated N reference numbers (second column) are specified in ISO 4063 (in the European Union published as EN ISO 4063 ). [ 1 ]

(a) Explain that Wikipedia's definition of cold welding in space is not the definition used by subject matter experts like the ESA, and (b) that the ESA has published an academic report explaining the difficulty in preventing what it considers to be cold welding in space. The ESA report is currently footnote 4:
