System and method of processing or combining materials and their use

Przedmiotem zgłoszenia jest system do obróbki lub łączenia materiałów zawierający źródło promieniowania (L) generujące wiązkę promieniowania o gęstości strumienia umożliwiającej uzyskanie zmiany postaci lub właściwości fizycznych zadanego materiału i skierowaną na obrabiany materiał (1), charakteryzujący się tym, że ma co najmniej jedno źródło zimnej plazmy atmosferycznej (A, A1, A2, B, B1, B2) kierujące strumień (9) zimnej plazmy atmosferycznej na obszar materiału (1) poddawany działaniu wiązki ze źródła promieniowania (L) lub częściowo albo całkowicie na ślad (2) obróbki. Zgłoszenie obejmuje także sposób obróbki lub łączenia materiałów z wykorzystaniem ww. systemu. A system for processing or joining materials comprises a radiation source (L) generating a beam of radiation with flux density that allows to obtain a change in the form or physical properties of the given material, and directing this beam at the treated material (1). The system has at least one source of cold atmospheric plasma - CAP (A, B) directing the CAP stream (9) to the area of material (1) exposed to the beam from the radiation source (L), or partially or entirely onto a trace (2) of treatment. The CAP source (A, B) has an adjustment of distance αof the nozzle (8) outlet from the treated surface of material (1) and is positioned coaxially with the radiation beam or inclined to this beam, and in such case it has an adjustment of angle (α, β) between the nozzle (8) axis and the surface of material (1). The system has a wire feeder for feeding a welding wire (3) and/or a powder feeder (5) and/or an additional material feeder that are mounted in the feeding head. Between the radiation source (L) and the material (1), above the feeding head or in the feeding head itself, a focusing and beam-guiding system is mounted, preferably with an adjustment of distance from the surface of treated material (1), in particular it is an optical system (S) focusing and guiding the beam of infrared radiation from a laser or a laser diode, preferably by means of an optical fiber. The system is applicable to carry out a new method of welding, cladding alloying, dispersing, surface remelting or surface heat treatment using a radiation source (L), where at least one stream (9) of cold atmospheric plasma is directed at the treated material (1).
