摘要： A method and apparatus particularly for additively manufacturing materials that are susceptible to hot cracking. The additive manufacturing process may include a leading energy beam (16) for liquefying a raw material to form a melt pool (20), and a trailing energy beam (17) directed toward a trailing region of the melt pool. The trailing energy beam may be configured to enhance agitation and/or redistribution of liquid in the melt pool to prevent hot cracking, reduce porosity, or improve other characteristics of the solidified part. The method and apparatus also may improve processing parameters, such as adjusting vacuum level to prevent volatilization of alloying agents, or providing a chill plate to control interpass temperature. The process may be used to form new articles, and also may be used to enhance tailorability and flexibility in design or repair of pre-existing articles, among other considerations.

摘要： A laser processing machine (100) includes a laser oscillator (11) . The laser oscillator (11) excites a laser beam having a wavelength in a 1 µm band or a shorter wavelength band. One process fiber (12) transmits the laser beam emitted from the laser oscillator (11). A focusing lens (27) that is formed of a facet lens is an example of a focusing optical element. The focusing optical element focuses, when a sheet metal (W1) as a workpiece is irradiated with the laser beam emitted from the process fiber (12), the laser beam on a plurality of spots in a unit area within a unit time, the unit area having a radius of 0.5 mm of an optical axis of the laser beam, and the unit time being a time from when the sheet metal (W1) starts to melt to when the melting of the sheet metal (W1) ends.
