Outline of Final Research Achievements

Welding fume is very small particles with size of nanometer or micrometer nucleated of metal vapor from welding wire and weld pool in arc welding. This study clarified influence of welding processes and welding parameters on welding fume formation process mainly through numerical simulation using a unified model consisting of a GMA welding model and a fume formation model in order to develop technique for controlling welding fume shape.
