| Research Abstract |
The switchback welding method can obtain a steady back bead and the penetration shape. The purpose of this research is to show the availability of this welding method in one side welding without thick plate. First, the mechanism of the movement phenomenon of the weld pool shape was analyzed when the switchback operated. Next, the best parameter of the switchback welding with the groove gap was detected. And the method of increasing the welding speed was developed. The availability of the switchback welding in joints other than the mild steel material such as titanium was verified.
