영문 초록

It is very important to form stable back bead, to decrease the distortion of weldments and to improve productivity in middle-thick butt joint welding of ships or steel structures. In a welding field, because SAW, FCAW or MAG welding has been generally applied to V-groove butt joint with root gap and root face, it is very difficult to make stable back bead without backing. therefore due to the increase in heat input and reduction in productivity caused by excessive groove area, the distortion of weldments is unavoidably increased. According, to solve the problems, a new welding process is necessary. The purpose of this study is to setup a optimum plasma keyhole welding condition range at bead on plate for plasma arc welding. We got the stable back bead in plasma keyhole welding at balance of many factors and applied to Y-groove butt joint without undercut
