Fusion 01
Fusion 01 : Nuclear Energy and Nuclear Disasters. (1) The joining of atomic nuclei to form a heavier nucleus, accomplished under conditions of extreme heat (millions of degrees). If two nuclei of light atoms fuse, the fusion is accompanied by the release of a great deal of energy. The energy of the sun is believed to be derived from the fusion of hydrogen atoms to form helium. (2) In welding, the melting together of filler metal and base metal (substrate), or of base metal only, which results in coalescence
