  In the remote welding system using CO₂ laser, laser beam can be rapidly transferred to a workpiece by moving mirrors of scanner system. So, it makes reducing the cycle time of welding process. We can also use and apply various kinds of weld beads by linear controlled mirrors. But most of the domestic car makers have usually applied use stitch-shaped weld bead. In that case, we don"t have the merit of remote welding system efficiently. Therefore, in this paper, we investigated the characteristic of strength weld according to patterns of weld bead on CO₂ laser welding. And we also studied the relationship between shape of weld bead and value of tensile load.
