Abstract

We present a coaxial laser metal deposition (LMD) system based on the single mode laser. The influence of input beam diameter on the ring spot properties such as spot shape, filling factor and ring width are investigated through numerical simulation. The result shows that the smaller ring spot and narrower ring width can be obtained by adopting the single mode laser in the coaxial LMD system, compared with the traditional coaxial LMD system based on the multimode laser (Flat-top beam). This also indicates that our system has advantages in the application of high-precision additive manufacturing (AM).
