In the present study, tungsten oxide nanorods were prepared by a plasma arcgas condensation technique where a gas nozzle was introduced to provide blowing gas.
By combining experiment with theoretical analysis, the influence of adding axial magnetic field on shape and properties of tungsten inert gas (TIG) welding arc and weld profile was studied.
