摘要： An additive manufacturing system includes an energy source and a material delivery device. The energy source is configured to direct an energy beam toward a component to form a melt pool. The material delivery device is configured to feed a wire toward the melt pool to deposit material on the component. In some examples, the material delivery device is configured to discharge a current to the wire to disengage the wire from the melt pool. In some examples, the material delivery device is configured to measure an arc voltage between the wire and the component.

摘要： A method for laser welding a stack of metal foils to a metal substrate includes securing the stack of metal foils between a surface of the metal substrate and a removable clamp such that a side of the stack, formed by edges of the foils, is located on an interior portion of the surface, and the clamp is set back from the side of the stack. A first laser welding step interconnects the foils with an initial laser-weld joint by serially tracing a plurality of lateral paths along the foil edges with a laser beam. A second laser welding step connects the stack of interconnected foils to the substrate by tracing, with a laser beam, a path along the interface between the initial laser-weld joint and the substrate surface. This two-step laser welding process circumvents the difficulties of welding together materials with highly disparate thicknesses in a single laser-welding operation.

摘要： A method for welding at least two aluminum-containing components includes subdividing an output laser beam into multiple partial beams directed onto the at least two components, so that multiple laser spots are generated on a surface of the at least two components, and traversing a welding contour with the multiple laser spots on the surface of the components. Centers of at least three laser spots of the multiple laser spots are arranged in a ring formation. The output laser beam is generated by a multifiber, so that each laser spot of the multiple laser spots on the surface of the components has a core portion and a ring portion. The welding contour is traversed at least partially a second time after the welding contour has been traversed a first time.

摘要： A method for welding at least two aluminum-containing components is provided. The components have an aluminum content of at least 75% by weight. The method includes subdividing an output laser beam into multiple partial beams directed onto the components, so that multiple laser spots are generated on a surface of the components, and traversing a welding contour on the surface of the components with the multiple laser spots. Laser spot centers of at least three laser spots of the multiple laser spots are arranged in a ring formation. The output laser beam is generated by a multifiber, so that each laser spot of the multiple laser spots on the surface of the components has a core portion and a ring portion, with a mean power density in the core portion being higher than a mean power density in the ring portion.

摘要： A three-dimensional (3D) printer is configured to introduce a liquid metal onto a first part and a second part while the first part and the second part are in contact with one another. The liquid metal subsequently solidifies to join the first part and the second part together to produce an assembly.

摘要： A method for manufacturing a joined body including two plate-like portions, the method including forming a joint part that comprises at least a portion of each of the two plate-like portions and joins the two plate-like portions; and irradiating the joint part with a beam, thereby to perform laser welding. The joint part includes at least one folded part, the at least one folded part is a bent part that is bent so as to be folded back in one of the two plate-like portions. First and second bases are formed at both ends of the bent part to face each other such that at least a portion of the other of the two plate-like portions is arranged between the first and second bases, the other of the two plate-like portions including no bent part.
