Abstract: The state of research of laser cladding in the stress concentration zone is briefly introduced.On the bais of optimal material and laser parameter,the laser cladding was used to treat the steel specimens of the fatigue test.The effects of claddng parameter on fatigue life are studied.The results of tests show that fatigue life of steel specimens treated with laser cladding can be considerably increased.

Key words: laser cladding fat igue life, stress concentration
