영문 초록

  In the remote welding system using CO₂ laser, laser beam is rapidly deflected by moving mirrors of scanner system and has focusable distance over 1000㎜ from workpiece. From such arrangement, various advantages and disadvantages arise. Remote welding is a highly efficient laser process. As the mirrors of the scanner system allow positioning speeds exceeding 700m/s, it becomes possible to reduce the welding cycle time. On the other hand, as there no the provision of shielding gas which is normally required for beam powers exceeding 3㎾, may become difficult task. Therefore, in this study, the influence of the various penetration of back bead by the different laser welding speed on the weld seam formation without shielding gas was investigated.
