Description of the invention

A useful model relates to beam welding of materials, in particular devices for heliowelding. 2 Heliowelding allows you to weld refractory materials in conditions of high sterility. Concentrated solar energy is used for welding directly in the V.S. concentrator. Dvernyakov,

Transmission of concentrated beam energy from the focal volume of the concentrator by means of flexible fiber optic cables provides an alternative solution for 710 process improvement.

A well-known device for spot welding, which includes a source of laser radiation, the energy of which is divided in half, and optical fibers, one end of which is fixed in the foci of the branches of the laser beam, and the free ends are directed to different points of the welding object (O.S. Stgciskepapk, K. UMer, roi meidipd Yesppidtse, Rai. 05 dt33074, V2ZK 025/00, 22.03.1988I.

The disadvantage of the device is that the free ends of the light guides are each directed to different points of the welding object. This makes it impossible to combine the energy powers of laser beams carried by different optical fibers.

The closest to the proposed useful model is a known device for transmitting the beam flow from the 29 focal volume of the optical system using flexible fiber optic cables, which includes a solar radiation concentrator and a flexible fiber optic cable fixed at one end in the focus of the concentrator |IV.В . Pasichnyi, G.F. Gornostaev, Study of optical fibers for the transmission of solar radiation from the focal volume of the solar concentrator to the technological zone. Engineering Physics Journal, 2004, volume 77, Mo3Z, p.1-4). The free end of the light guide can be manipulated near the surface to be heated. with

The disadvantage of the device is the low power of the transferred energy flow due to the fact that the existing light guides, made on the basis of quartz glass or polymers, are not capable of transferring energy greater than 30 W/cm?, which is usually not enough for the welding process of refractory materials. at

The purpose of the utility model "Device for welding materials with concentrated solar radiation" Ge is to increase the output power of the device.

The problem is solved due to the fact that the device, which consists of a concentrator of solar cm radiation and a flexible fiber optic fiber, fixed at one end in the focus of the concentrator, is equipped with two or more pairs of concentrator - optical fiber, while the concentrators are arranged on one frame with a common guidance mechanism and following the Sun, and the other ends of the light guides are assembled into a harness and fixed in a bracket that can move with six degrees of freedom. The increased number of concentrators, each of which concentrates the energy corresponding to the optimal carrying capacity of the optical fiber, and, accordingly, the increased number of optical fibers, each of which transmits its energy, allow to additively increase the total power of the transmitted energy, and the free ends of the optical fibers , collected in a harness and fixed in a clip that can move freely, are able to transfer the total energy to the desired area of the welded surface of the material. yuyu 395 In Fig. a schematic diagram of the proposed device is shown. Two hubs (|1| arranged on one moving frame |2). In each of the foci of the concentrators, flexible fiber optic light guides (Ж) are fixed at one end. The other ends of the light guides are assembled into a bundle and fixed in a bracket (4), which can move with six degrees of freedom.

The device works as follows. With the help of the mechanism of pointing and following the Sun (not shown in Fig. (o) 50), the concentrators |(|1) are pointed at the Sun. Concentrated solar energy enters the ends of the light guides (ZI "z) and is transmitted through them to the other ends, from where they exit in the form of rays. The output ends of the waveguides, being assembled together and fixed in the clip (4), emit energy equal to the sum of the energies collected by each concentrator. The moving clip is able to direct the total flow of energy at any angle to the desired place on the welded surface of the material. To achieve sufficient total energy for the welding process, the necessary number of concentrators and light guides can be added. c Example of the implementation of the invention. A parabolic concentrator with a diameter of 40 cm with a fixed at its focus, a multi-module flexible light guide with a diameter of 5 mm was guided by a mechanism to the Sun, and the free end of the light guide was directed to the joined steel plates with a thickness of 2 mm. The input flux of 250 W/cm 2 turned out to be insufficient for welding the plates - they only heated up to 550 9bC. Then they took four because they are arranged on one movable frame concentrators with a diameter of 40Osm with multi-module flexible optical fibers with a diameter of 5mm fixed in their focuses and directed them all at once to the Sun. The free ends of the optical fibers were assembled into a bundle and fixed in a bracket that can move with six degrees of freedom, that is, in an arbitrary direction, turning at an arbitrary angle. The clip with the output ends of the light guides was oriented on the joined steel plates with a thickness of 2 mm and after 1 minute the plates were welded. 65 Welding became possible due to the increase in the output power of the device due to the increase in the number of concentrators and the combination of the solar radiation concentrated by each of them and transmitted through the flexible optical fibers together due to the fact that the free ends of the optical fibers were collected in a harness and fixed in a clip.

The useful model can be used to weld traditional structural metal materials as an alternative to electrowelding in the absence of electrical power, as well as refractory materials both on Earth and in space.
