A method and system to manufacture workpieces employing a high intensity energy source to create a puddle and at least one resistively heated wire which is heated to at or near its melting temperature and deposited into the puddle as droplets.

A braze alloy includes by atom %, about 30% to about 60% iron, 0 to about 40% nickel, and about 10% to about 20% in total of melting point depressants selected from the group consisting of phosphorous, carbon, boron, and silicon.

The present applicant presents a structure intended for high temperature use above 30 C. comprising multiple components having metal-to-metal or metal-to-ceramic contacting surfaces wherein the surfaces are joined by a braze composed of pure aluminum. Anticipated devices include but are not limited to igniters as well as electronic applications in the automotive and aerospace industries.

The present invention discloses a method and a system for additive manufacturing of a complex metal part by sheet lamination, and belongs to the field of manufacturing. A three-dimensional data model of a part is sliced into metal sheets, the metal sheets are molded, and each metal sheet is combined into the part by using diffusion welding or friction welding. A diffusion welding or friction welding technique is introduced in additive manufacturing, so that a production capacity of additive manufacturing is further expanded and supplemented, so as to manufacture parts with higher precision and better finish quality.

The present disclosure relates to an additive manufacturing method. The method includes applying metallic powder in layers to a base surface. The base surface is formed in part by a base plate and in part by at least one insert arranged in a through opening in the base plate. The metallic powder layers are bonded in some region or regions by heating, whereby an object having connecting structures that are connected to the at least one insert is manufactured. After manufacture is finished, each insert is adjusted within a through opening relative to the base plate, thereby separating at least parts of the connecting structures from the insert.

A method for the production of a heat exchanger is provided, particularly a sorption heat exchanger, in which several components of the heat exchanger have a ferrous based material, such as pipes, the pipes finishing the bottoms, and the bottoms and the pipes enclosing the housing components are coffered and then soldered. In one method, which reliably realizes the soldering of the joints with different widths, a brazing foil is introduced during the coffering of the components of the heat exchanger formed of steel or stainless steel between the joints of the components of the heat exchanger, and then the joints are filled with a low-melting solder and soldered without flux material.

The present disclosure relates to a method which uses welding in order to join a FeCrAl alloy to a FeNiCr alloy by using a specific filler metal. The present disclosure also relates to a product obtained thereof. Further, the present disclosure relates to the use of the method, especially in high temperature applications.

A method to restore a cast iron part is provided. The method includes providing the cast iron part with an impaired surface. The method further includes depositing a layer of repair material on the impaired surface of the cast iron part. The method further includes exposing the layer of repair material to heat to generate a cladding layer. The method further includes cooling the cladding layer.

Apparatus, systems, and methods for synthesis of powder from asteroids or meteorites and the use of the powder as the feed source for additive manufacturing systems deployed in space. Location and analysis of suitable asteroids or meteorites is demonstrated on earth and later used to produce components and products in space using natural space resources. The method includes the steps of locating an asteroid, making contact with the asteroid using meteorites on earth, harvesting material from the asteroid, processing material from the asteroid producing additive manufacturing quality powder, using the additive manufacturing quality powder as a feed stock for additive manufacturing in space, and completing the parts or products by the additive manufacturing in space.

The invention provides a wound magnetic core which is configured by winding an Fe-based amorphous alloy ribbon, the wound magnetic core containing a recess row including plural recesses formed by laser irradiation in a central part of the Fe-based amorphous alloy ribbon in a width direction, in which a ratio of a length of the central part to a total width is from 0.2 to 0.8.
