AISI 316L stainless steel was joined by CO2 laser beam welding method.
In vitro cell interactions with base metal and laser welded sample were investigated.
Base metal shows better cell viability when compared to laser welded sample in the short term period.
Laser welded sample shows better cell viability when compared to the control group.
The most ions released from base metal in the long term period as compared to the laser welded sample.
