Abstract: The state of the art of laser strengthening technology on material and structure are briefly introduced. On the basis of optimal material parameter, a simulated fatigue test was conducted on a Y7 airplane stringer joint. The effects of irradiant parameter on fatigue life was studied. The results of tests show that fatigue life of the components treated by laser irradiation can be considerably increased.

Key words: laser, irradiation strengthening, fatigue life
