Herein, a novel process of direct deposition (cladding) of wires with multi-beam laser and on-centerline heat is proposed and tested. In the single-pass deposition experiment, the efficiency of laser deposition of hot wire is higher than that of cold wire, and the clad beads and the substrate easily bond together. Hot wire is used in tests for deposition with multidirectional laser scanning, tests for single-layer multi-pass lapping deposition, and tests for deposition of thin walls and solids. Results show that stable and continuous wire-feeding deposition can be finished in the proposed process. The surface of the finished clad bead is smooth with uniform sections, and lacks burrs or spheroidization defects. Moreover, the deposited surface of the sample is substantially planar in any scanning direction. The deposited cuboid solid produced by this process demonstrates that the new process can be used to form three-dimensional complex structures.
