Low-Power YAG Laser Welding Process Under Vacuum Condition |
| |
| Abstract: | The characteristics of using lowpower YAG laser welding 304 stainless steel under different vacuum degree are investigated. In order to confirm that vacuum condition can restrain plasma effectively, the effect of welding speed and energy input on welding penetration are analyzed. Macroappearances of the seam welded under different vacuum conditions are compared, and the microstructure as well as microhardness are tested. |
