An in‐situ TEM nanowelding process via Joule heating was used to achieve superstrong CNT‐carbide‐metal contacts, in which all shells of a multiwalled CNT contact the tungsten wire through the intermediate tungsten carbide layer. A remarkably high tensile strength (5–15GPa) and ultralow resistance(<1 kΩ) were documented for the heterojunctions, which were also sufficiently robust in CNT field‐emission applications.
