The augmenting cylinder is made of an augmenting material having a second hardness, is fixedly secured in the first interior of the boss cylinder, and has a second interior defined by a second cylindrical shaped wall, a base rim, and a second opening. The second hardness is greater than the first hardness. The fastener is fastened to the multi-material boss via the second opening of the augmenting cylinder having the higher liquidus temperature and greater hardness.

Provided is a tape-shaped contact member including a tape-shaped contact material. At least one wire-shaped brazing material is bonded to the tape-shaped contact material, at least one projection including the brazing material and protruding from a surface of the contact material is formed in a cross-sectional shape, a diffusion region containing a metal component forming the brazing material is formed along an interface with the brazing material inside the contact material, and the diffusion region has a thickness of 2 μm or more and 10 μm or less. A chip-shaped contact component can be obtained by cutting the tape-shaped contact member to an arbitrary length. The present contact component is useful as a constituent member for a switching electrical contact, and capable of adapting to height reduction of the electrical contact. The present invention can also contribute to reduction of occurrence of poor bonding.

The tube wall may have at least one curved wall area that extends between two adjacent comb-shaped support points. Between the at least one curved wall area of the tubular connecting part and the receiving wall inner side of the receiving part at least one gap is arranged where a solder is received to establish a materially bonded and fluid-tight connection.

A method for soldering a solar cell, includes: placing a plurality of back contact cells on a soldering platform, where back surfaces of the back contact cells face away from the soldering platform, and electrodes corresponding to two adjacent back contact cells have opposite polarities in a connection direction of a plurality of to-be-connected ribbons; placing the plurality of to-be-connected ribbons on the electrodes of the plurality of back contact cells by using a first clamping portion, a second clamping portion, and a plurality of third clamping portions, where the first clamping portion, the second clamping portion, and the plurality of third clamping portions respectively correspond to head ends, tail ends, and middle portions of the plurality of ribbons; and heating the plurality of ribbons by using a heater to connect the plurality of ribbons to the plurality of back contact cells.

A method for producing a heat exchanger having tubes that are each received at a longitudinal end side in an associated header, the tubes and the headers are formed out of aluminium. The method may include soldering the tubes and the headers to one another to form a coolant-conducting channel structure, and cold-forming the heat exchanger following the soldering of the tubes to the headers such that strength is thereby increased.

A method for creating an electric heating source, including a body equipped with one or more housings containing mineral-insulated heating cables. The housings communicate with one or more reservoirs which accept a purely metallic solder material in solid, powder or sheet form. The device is heated in a vacuum degassing plateau, followed by a casting plateau during which the solder melts and fills the housing around the heating cables, resulting in full metal contact between the cables and the body, providing a more uniform temperature and a shorter response time to heating or cooling. Also, a heating source obtained in this manner, including an infrared faired source or an immersion heater for the heating of a liquid bath of molten metal.

The invention relates to a method of producing a plate arrangement comprising two plates (1, 2) which, at least in sections, have an intermediate space (4) located between them and a constant distance (d) to one another and/or are arranged parallel to one another and between which a fusible solder material (3, 3′) is arranged. The task of setting a defined distance between the plates as accurately as possible is solved according to the invention by creating a pressure difference between the intermediate space (4) between the plates and the outer space surrounding the plates in such a way that the pressure in the outer space is higher than in the intermediate space (4) and that the temperature of the solder material (3, 3′) is at least temporarily raised above its melting temperature during the existence of the pressure difference.

The present invention pertains to a brazing method and a brazing apparatus. This brazing method comprises: a brazing material supply step for supplying a brazing material to a to-be-welded part; and a laser irradiation step for irradiating the brazing material having been supplied to the to-be-welded part with a laser beam while moving the laser beam along a brazing direction to form a welding bead. In the laser irradiation step, a gas is injected toward an area to be injected with gas, which is an area encompassing the welding bead located rearward of a laser-irradiated portion of the brazing material in the brazing direction, from above said area or from a front side of said area in the brazing direction.

A brazing apparatus and method for brazing an anode target plate of an X-ray generator are disclosed. The brazing apparatus comprises: a vacuum part for providing, during brazing, a vacuum environment at least for a target plate main body formed of an alloy, a brazing material, and a substrate; an induction brazing part for applying an induction current to the target plate main body, the brazing material and the substrate in the vacuum part so as to achieve heating to a temperature higher than the melting point of the brazing material, causing the substrate to be welded to the target plate main body through melting of the brazing material and a resulting reaction; and a directional energy welding part for applying a generated directional energy beam to a position of lower temperature determined on the target plate main body to perform heating.
