A system is disclosed for depositing material on a component. The system includes a deposition device operatively coupled to a fiber optic Nd:YAG laser. The deposition device includes a focusing prism that focuses the Nd:YAG laser at a focal area on a bladed disk, where the focal area on the bladed disk is between two blades of the disk. The system further includes an imaging means that views the focal area of the component. The imaging means and the fiber optic Nd:YAG laser each are positioned in a substantially similar optical relationship to the focal area on the bladed disk The system further includes an additive material delivery means that delivers additive material to the component at the focal area on the component.

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.

A coolant supply system includes a coolant tank for accumulating coolant generated by using deionized water, a coolant supply passage for supplying the coolant in the coolant tank to the laser processing head, an electric conductivity meter for measuring an electric conductivity of the coolant to be supplied to the laser processing head, a drainage passage capable of draining the coolant from the coolant tank, an electromagnetic valve provided on the drainage passage, and a controller that controls open/close operations of the electromagnetic valve. The controller turns the electromagnetic valve from a closed state into an open state to drain the coolant in the coolant tank through the drainage passage when a measured value of the electric conductivity meter exceeds over a preset upper limit value.

A system that uses a scalable array of individually controllable laser beams that are generated by a fiber array system to process materials into an object. The adaptive control of individual beams may include beam power, focal spot width, centroid position, scanning orientation, amplitude and frequency, piston phase and polarization states of individual beams.
