| Abstract: | In this paper,the plasma shape in deep penetration laser welding mild steel is observed using a high speed camera system,and the effect of the processing parameters such as laser beam defocus on plasma are experimentally investigated. And the plasma shape in different welding mode is grasped with high speed camera. |
