| Popis: | The purpose of this study is to develop the ultra-high-speed GTA welding process with hot-wire system using pulsed current to heat filler wire. For precise control of the ultra-high-speed (over 5 m/min) GTA welding, it is necessary to understand deeply the ultra-high-speed welding phenomenon. The melting phenomenon of filler wire was observed in detail by a high-speed camera and filler wire temperature was measured precisely by a radiation thermometer. As a result, precise temperature distribution of filler wire and clearly visualized wire melting phenomenon was obtained. |
