Paper Abstract

The surfaces of Ti6Al4V alloy EBW (Electron beam welding) were processed by CO2 laser quenching, and residual stresses of EBW were measured with X-ray stress tester X-350A. The mechanism of residual stress was analyzed, the effects of assistant gas and laser power and spot diameter on residual stresses in EBW of Ti6Al4V alloy is investigated. Experimental results show that residual stresses in EBW are increased obviously by CO2 laser quenching under the given laser parameters, which improve its mechanical performances.
