A mist generating apparatus sprays a surface of an object (P) to be treated with a carrier gas (CGS) of mist (Mst) of a solution containing fine particles or molecules of a material substance, so that a layer of the material substance is deposited on the surface of the object (P) to be treated. The mist generating device includes a mist generator (14) for atomizing the solution to feed the carrier gas (CGS) containing the mist (Mst), and an ultraviolet irradiator (20B) for applying ultraviolet rays having a wavelength of 400 nm or lower to the mist (Mst) floating in the carrier gas (CGS) in a flow path extending from the mist generator (14) until the carrier gas (CGS) is sprayed on the surface of the object (P) to be treated.

The present disclosure provides a device and method for manufacturing a coated welding rod. The device for manufacturing a coated welding rod includes a grabbing device, a heating device, and a flux storage device. The heating device is configured to heat a welding rod in the grabbing device. A flux in granular form is stored in the flux storage device, the grabbing device is configured to transport the heated welding rod into the flux storage device, and the heated welding rod is configured to heat the flux surrounding the welding rod into a viscous glassy state so that the flux in the viscous glassy state adheres to the surface of the welding rod. The heated welding rod enables the granular flux to be formed into a viscous glassy state so that the flux can be adhered directly to the surface of the welding rod.
