Yini i-brazing

I-Brazing yinqubo yokujoyina insimbi ehilela ukusetshenziswa kwensimbi ye-filler, encibilike futhi yasatshalaliswa phakathi kwezindawo ezimbili noma ngaphezulu ezihlanganiswe kakhulu. Le ndlela ihlukaniswe ekushisweni ngamazinga okushisa aphansi aphansi, lapho izinsimbi eziyisisekelo zingancibiliki kodwa zifudunyezwa emazingeni okushisa angenhla kwama-450 ° C (cishe ama-842 ° F). I-filler Metal ngokujwayelekile inendawo yokuncibilika ngaphezu kwalokhu kushisa kepha kuphansi kunaleyo yezisebenzi zomsebenzi. I-Brazing isetshenziswa kabanzi emikhakheni ehlukahlukene ngenxa yokusebenza kwayo ekwakheni amalunga aqinile, aqinile.

Inqubo yokubhidliza

Inqubo yokubhidliza ingahlukaniswa ibe yizigaba ezimbalwa ezibalulekile:

1. Ukulungiselela izindawo eziphakeme: Izindawo zensimbi okufanele zihlanganiswe kufanele zihlanzwe kahle ukuze zisuse noma yimiphi i-oxides, ukungcola noma amafutha. Lokhu kungenziwa ngezindlela zokuhlanza ezisebenza ngomshini njengokugaya noma ukugaya, noma izindlela zamakhemikhali njengokuthathwa.

2. Umhlangano: Ngemuva kokuhlanza, izakhi zihambisana eduze, ziqinisekisa ukuthi kufanelekile. Ukuqondanisa kahle kubalulekile ngoba isikhala phakathi kwezingxenye sithinta kahle ukuthi i-filler insimbi izogeleza kahle kanjani futhi isibopho.

3. Ukushisa: Umhlangano ufudunyezelwa usebenzisa izindlela ezahlukahlukene, kufaka phakathi iTorch Brazing, i-Furface Brazing, Ukuvuka kwamabhuleki, noma ukumelana nokuphikiswa. Ukushisa kumele kube umfaniswano ngokwanele ukufinyelela amazinga okushisa adingekayo ngaphandle kokudala izinsimbi eziyisisekelo ukuncibilika.

4. Ukusetshenziswa kwe-filler Metal: Lapho izinsimbi zesisekelo zifudumele ngokwanele, i-filler Metal, evame ukuba ngendlela yezinduku, amashidi, noma amapopi, kwethulwa. Idonswa ekuhlanganiseni ngesenzo se-capillary. Insimbi ye-filler bese igeleza ingena kwigebe phakathi kwezicucu zensimbi, yakha isibopho esiqinile njengoba iqina.

5 Umhlangano ophelile uvame ukuhlolelwa ukuvivinya ukuqinisekisa ukuthi ukuhlangana kuhlangabezana nezincazelo ezidingekayo.

Izinzuzo zokubhidliza

I-Brazing inikeza izinzuzo eziningana uma kuqhathaniswa nezinye izindlela zokujoyina njenge-welding noma i-soldering. Enye yezinzuzo eziyinhloko amandla okujoyina izinsimbi ezingafani. Lokhu kunamandla kubalulekile ezimbonini lapho izinto ezahlukahlukene kufanele zisebenze ngokubambisana, njengokwakhiwa kwabashisi bokushisa, izingxenye zezimoto, kanye namadivayisi we-elekthronikhi.

Enye inzuzo ebalulekile umthelela oncishisiwe we-thermal ezisebenzini. Njengoba izinsimbi eziyisisekelo azincibiliki ngesikhathi senqubo, kunengozi encane yokufaka kabusha noma yokuguqula izakhiwo ezibonakalayo ezinjengobulukhuni namandla. Lesi sici futhi sivumela uhla olubanzi lwezinto zokwakha luhlanganiswe, kubandakanya nalezo ezinzima ukuwela.

Ngaphezu kwalokho, amalunga aphanjisiwe akhombisa izakhiwo ezinhle zemishini, ezenza zilungele izinhlelo zokusebenza ezidinga amandla aphezulu nokuqina. Inqubo futhi ivumela ukwakhiwa kwama-geometries ayinkimbinkimbi okungenzeka ukuthi kube yinselele ukufeza nezinye izindlela zokujoyina.

Izicelo ze-Brazing

I-Brazing isetshenziswa emikhakheni ehlukahlukene, kufaka phakathi:

Izithuthi: Ezokukhiqiza izimoto, ukubheja kuvame ukusetshenziselwa ukujoyina izakhi kuma-radiator, amasistimu wokuqeda amandla, kanye nemihlangano yokuhambisa.

I-Aerospace: emkhakheni we-aerospace, i-brazing isetshenziswa ukuhlanganisa izingxenye ezibucayi ezifana nama-turbine blades kanye nabashisi bokushisa, lapho ukuthembeka kubaluleke kakhulu.

I-Electronics: I-Brazing isetshenziselwa ukudala ukuxhumana kumadivayisi we-elekthronikhi, ukuhlinzeka ngesibopho esiqinile sezinto okufanele zikwazi ukubekezelela ukucindezelwa okushisayo nokwenziwe ngomshini.

I-Plumbing: Ku-Plumbing and HVAC Systems, I-Brazing iyindlela ejwayelekile yokujoyina amapayipi nokufakwa kwamapayipi, kuqinisekiswe ukuxhumana okungenakuvuza.

Ukugcina

Ngokufingqwa, ama-Brazing kuyindlela ebalulekile ezinhlelweni zesimanje zokukhiqiza nezinqubo zokulungisa, enikeza amalunga aqinile futhi aqinile ngaphandle kwesidingo sokuncibilikisa izinsimbi eziyisisekelo. Ukuguquguquka okuhlukahlukene, ukusebenza kahle, kanye nekhono lokujoyina izinto ezingafani neze kwenze ithuluzi elikhulu kuzo zonke izimboni ezahlukahlukene. Njengobuchwepheshe buthuthuka, ukusetshenziswa kanye nezindlela zokubheja kuyaqhubeka ukuvela, kuthuthukisa futhi ukubaluleka kwako ebunjiniyela kanye nasekukhiqizweni.
