Embodiment Construction
[0012] The present invention will be further described below in conjunction with specific embodiment:
[0013] See attached figure 1 As shown in this embodiment, a metal parts laser light internal wire feeding cladding laser shock forging composite additive manufacturing method described in this embodiment, the steps are as follows:
[0014] (1) The circular solid beam of the continuous laser beam is converted into a hollow conical focused beam through the optical path, and the coaxial wire feeding method in the light is used to clad the molten metal wire by thermal effect, while another pulsed laser beam is used The shock wave mechanical effect performs synchronous impact forging on the cladding layer in the temperature region prone to plastic deformation, and performs composite manufacturing;
[0015] (2) The cladding layer is stacked layer by layer to form the workpiece.
[0016] During the manufacturing process, the coaxial wire feeding speed of the continuous laser beam...
