Disclosed is a method for an all-laser hybrid additive manufacturing. After a matrix is obtained by means of selective laser melting forming, a subtractive forming is carried out on the matrix by means of a pulse laser to form a cavity, and the cavity is then packaged to obtain a forming material with an internal cavity structure. A laser precision packaging method is used in the method based on the melting of the laser selective region. Also disclosed is the apparatus, comprising a laser unit (2), a control unit (4) and a forming unit (6). The laser unit is in light path connection with the forming unit, and the control unit is electrically connected with the laser unit and the forming unit respectively. The laser unit comprises a first laser light source to and a second laser light source. The forming unit comprises a welding unit (68), and the welding unit is controlled by the control unit and is matched with the laser unit for the additive manufacturing.

Provided is a metal jointed body, joined by solid-phase joining in the atmosphere, in which no protrusion of molten joining material occurs, that improves dimensional stability. A metal jointed body is formed by (A) making Ag films of two metal laminated bodies opposed to each other, the metal jointed body being configured by sequentially laminating a Zn film and an Ag film on an Al substrate serving as a member to be joined, and (B) bringing the Ag films into contact with each other, then (C) heating is performed while pressurizing, and closely adhering and solid-phase joining the Ag films to each other. The completed metal jointed body is a portion where Al—Ag alloy layers are provided on both sides of an Ag—Zn—Al alloy layer to join the Al substrates to each other.

A mobile waterstop welding apparatus includes a first and second support member for supporting a first and second waterstop section, respectively. The second support member is movable between a loading configuration, a heating configuration, and a welding configuration. In the loading configuration, the first and second support members are spaced apart so that the first and second waterstop sections may be loaded onto the first and second support members. In the heating configuration, the first and second support members are spaced apart so that a heating iron may be placed in-between respective welding ends of the first and second waterstop sections. In the welding configuration, the first and second support members are moved towards each other so as to weld the first and second waterstop sections together at their respective welding ends. During the welding process, a spring assembly may urge the first and second support members towards each other.

A brazing process using Nickel(Ni)-Carbon as graphite(Cg) alloys, Ni-Cg-Molybdenum(Mo) alloys, and Ni-Cobalt(Co)-Cg-Mo alloys for brazing together ceramics, ceramics to metals, metals to metals. Semiconductor processing equipment made with the use of Ni-Cg alloys, such as heaters and chucks. Semiconductor processing equipment components and industrial equipment components using a highly wear resistant surface layer, such as sapphire, joined to a substrate such as a ceramic, with a Ni-Cg alloy braze.

A method of attaching a cladding element to a base element. A first inner side of the cladding element is positioned spaced apart from a second inner side of the base element to define a slot therebetween, and one or more heating elements are located in the slot. A non-oxidizing atmosphere is provided in the slot, and the heating element is energized, to heat at least portions of the cladding element and the base element to a hot working temperature. While at the hot working temperature, the first and second inner sides are engaged with each other, and one or both are moved relative to the other, for plastic deformation of the first and second inner sides, to subject the portions of the cladding element and the base element to shear stresses. The portions are allowed to cool, for recrystallization thereof.

A method for producing a sliding element, providing a first band-shaped or strip-shaped metallic material of a thickness, wherein the first material has apertures which extend over the entire thickness of the first material, providing a second band-shaped or strip-shaped metallic material of a thickness, areally connecting the first band-shaped or strip-shaped material to the second band-shaped or strip-shaped material by laser roll cladding such that a band-shaped or strip-shaped composite material is formed, which has a longitudinal direction X and a transverse direction, and has a thickness oriented perpendicularly with respect to the longitudinal and transverse directions. The method further includes bending the composite material about an axis oriented parallel to the transverse direction of the composite material, such that a sliding element is formed which has cutouts on its running surface that are formed at least partially from the apertures of the first material.
