Extreme　high-speed　laser　material　deposition　(EHLA)　allows　the　additive　manufacturing　to　a　mass　production　due　to　its　enhanced　scanning　speed　and　reduced　detrimental　to　the　substrate.　It　provides　the　potential　for　feasible　repair　of　valuable　metal　engineering　structures　those　are　complex　in　geometry.　In　the　process　of　EHLA　the　material　inherits　a　memory　of　the　complex　thermal　and　mechanical　history　in　the　form　of　microstructural　changes　and　residual　stress　distribution.　Numerical　modelling　of　the　residual　stresses　within　EHLA　produced　mechanical　components　is　of　great　significance　for　improving　the　quality　and　reliability　of　design　for　structural　integrity.　In　the　present　study,　we　proposed　a　procedure　for　constructing　residual　stress　field　caused　by　heat　involved　processes　through　eigenstrian　method.　Eigenstrain　variation　is　expressed　by　a　series　of　functions　of　the　distance　from　the　object　boundary　in　the　cross-sectional　plane　of　a　deposition.　We　applied　this　procedure　to　the　reconstruction　of　residual　stress　for　EHLA　produced　AISI　4140　structures,　and　validated　the　results　by　experimental　data　from　the　electronic　speckle　pattern　interferometry　(ESPI)　associated　hole　drilling　measurement.　The　good　consistency　of　predicted　results　and　experimental　data　indicates　that　the　procedure　provides　an　approach　for　evaluating　the　residual　stresses　of　an　EHLA　manufactured　component.　Fatigue　performance　of　a　deposited　structure　is　assessed　according　to　Dang　Van　criterion　with　considering　the　initial　stress　introduced　by　the　cladding　processes.
