An　orthogonal　test　method　was　used　to　optimize　parameters　for　Ni60A-25%　tungsten　carbide　(WC)　laser　cladding　layers.　Meanwhile,　the　tensile　properties　of　the　optimized　laser　cladding　layer　are　explored.　A　multi-factor　analysis　of　variance　(ANOVA)　was　conducted　to　examine　the　effect　of　factors　(laser　power-A,　scanning　speed-B,　powdering　rate-C,　and　spot　diameter-D)　and　interactions　on　responding　variable.　The　results　showed　that　the　interaction　of　scanning　speed　and　powdering　rate　with　spot　diameter　has　a　more　pronounced　impact　on　the　dilution　rate　compared　to　a　single　factor.　Based　on　the　ANOVA　of　the　dilution　rate,　the　optimal　combination　of　process　parameters　was　A3C2B1D3.　Furthermore,　the　optimal　combination　of　process　parameters　was　C3B2D3A3　for　the　effective　area.　The　results　showed　that　the　yield　strength　of　the　specimens　was　512.3　MPa　and　509.7　MPa,　and　the　tensile　strength　was　646.3　MPa　and　605.7　MPa　for　process　parameters　I　and　II,　respectively.
