Vertex Offset Model of Cladding Layer by Annular Laser Metal Deposition Based on Response Surface Methodology
With A304 stainless steel as the substrate and Fe313 as the cladding powder,the effects of laser power,scanning speed,collimating pressure,inclining angle of substrate and their interactions on the vertex offset of the cladding layer were studied.The results show that the inclining angle of substrate has the greatest influence on the vertex offset,followed by the laser power.With the increase of the inclining angle of substrate,the vertex offset of the cladding layer increases and then decreases.With the increase of laser power,it gradually increases.The mathematical model between the process parameters(laser power,scanning speed,collimating pressure,inclining angle of substrate)and the vertex offset of the cladding layer is established by the response surface methodology(RSM).The collimating pressure and inclining angle of substrate have significant interaction effects on the vertex offset,and the laser power and inclining angle of substrate have significant interaction effects on the vertex offset.
