Umehluko phakathi kokubhidlizwa kanye ne-fusion welding

I-Welding kanye ne-Brazing kungamasu amabili ajwayelekile asetshenziselwa ukujoyina izinsimbi, kepha asebenza ezimisweni ezahlukahlukene futhi alungele izinhlelo ezihlukile. Ukuqonda umehluko phakathi kokubhidlizwa kanye nokufakelwa kwe-fusion kubalulekile onjiniyela, ama-Facricators, nanoma ngubani obandakanyeke ezinqubweni zokukhiqiza. Lo mbhalo uhlola umehluko omkhulu phakathi kokubhidliza kanye ne-fusion welding, kufaka phakathi izinqubo, izinto zokwakha, amasu, izinzuzo, kanye nokusetshenziswa kwendlela ngayinye.

Ukuchazwa kanye nenqubo

I-Brazing yinqubo yokujoyina insimbi engahileli ukuncibilika kwezinsimbi eziyisisekelo. Esikhundleni salokho, isebenzisa insimbi ye-filler, enamaphuzu aphansi ancibilikayo kunezisebenzi zomsebenzi, ngokuvamile ngenhla 450 ° C (842 ° C). Ngesikhathi sokubhidlizwa, izinsimbi eziyisisekelo ziyafudumala, okwenza i-filler metal inyathele bese ingena ekuhlanganiseni ngesenzo se-capillary. Njengoba umhlangano upholile, insimbi ye-filler iqinisa, yakha isibopho esiqinile phakathi kwezinto.

Ngakolunye uhlangothi i-Fusion Welding, ngakolunye uhlangothi, kubandakanya ukuncibilika kwezinsimbi eziyisisekelo kanye nezinto zokuhlanza (uma zisetshenziswa) ezindaweni zazo zokujoyina. Inqubo idala ichibi elibunjiwe eliqina ekupholiseni, kwakha ukuhlangana okuqhubekayo. I-Fusion Welding ibandakanya izindlela ezahlukahlukene ezifana ne-Arc Welding, i-Welding Welding, i-Laser Welding, ne-Electron Beam Welding. Isici esibalulekile se-Fusion Welding ukuthi sincike ekunciphiseni okuphelele kwezinsimbi ezihlanganisiwe.

Ukucatshangelwa Kwezinga Lokushisa

Omunye womehluko oyinhloko phakathi kokubhidlizwa kanye nokufakelwa kwe-fusion izinga lokushisa lapho inqubo ngayinye yenzeka khona. I-Brazing yenziwa emazingeni okushisa aphansi, okusho ukuthi ingasetshenziswa ukujoyina izinto ezingase zizwele ukushisa okuphezulu. Lokhu kulawulwa kwe-thermal kusiza ekunciphiseni impi, ukuhlanekezela, kanye nezinguquko ezintweni ezibonakalayo.

Ngokuphambene, ukufudumala kwe-fusion kuhlanganisa amazinga okushisa aphezulu avame ukwedlula iphuzu lokuncibilika lezinsimbi eziyisisekelo. Lokhu kushisa okuphezulu kungadala ushintsho oluphambili ekuhlelekeni kwezinsimbi ezenziwayo. Ngenkathi lokhu kungaba yinzuzo kwezinye izimo, njengokudala amalunga aqine kakhulu, kungaholela nezinselelo ezifana nezindawo ezithintekile ukushisa ezingase zisebenzise izinto ezisisekelo.

Izinsimbi ze-filler

Olunye umehluko obucayi lulele ekusetshenzisweni kwezinsimbi ze-filler. Ku-Brazing, i-filler Metal ikhethwe ngokuqondile ukuze ibe nephuzu elincibilikayo eliphansi kunalena yezinsimbi eziyisisekelo. Izinto ezijwayelekile ze-filler zifaka ama-alloys ethusi, isiliva, kanye ne-aluminium. Ukukhethwa kwensimbi ye-filler kwenzelwe ukuthuthukisa izakhiwo zokuhlangana, njengokumelana nokugqwala namandla.

Ku-fusion welding, insimbi ye-filler kungenzeka noma ingahle isetshenziswe, kuya ngendlela esetshenzisiwe. Lapho kufakwa impahla ye-filler, kukhethwe ngokujwayelekile ukufanisa izakhiwo zezinsimbi eziyisisekelo eduze. Lokhu kuqinisekisa ukuthi ukuhlangana kwe-welded kugcina amandla nokukhohlisa kwezinto zoqobo.

I-Joint Design and Fit-up

Ukubopha okuvumela ukubekezelela okwengeziwe ekwakhiweni okuhlangene kune-fusion welding. Isenzo se-capillary sensimbi ebiwe ye-molten singagcwalisa izikhala phakathi kwezingcezu ezihlanganisiwe, ukwenza amabhuleki alungele amalunga anembe kangako ngokufanele. Lokhu kungaba yinzuzo lapho kusebenza ngezakhi ezibunjiwe noma emihlanganweni emincane edinga ukubekezelela okukhulu.

Ngakolunye uhlangothi i-Fusion Welding, ngakolunye uhlangothi, ifuna ukuqina okulula phakathi kwezinsimbi ukuqinisekisa i-Weld ephumelelayo. Izikhala noma ama-misaligments angaholela ekuhlanganeni okubuthakathaka noma okungaphelele, aqokomise ukubaluleka komhlangano oqondile ngaphambi kokufudumala.

Izinzuzo

Zombili izikejana zokufafaza kanye nokufakelwa kwe-fusion zinikela ngezinzuzo ezihlukile ngokuya ngesicelo. 

Izinzuzo ze-Brazing:

1. Izinsimbi ezingafani

2. Ukuhlanekezelwa okuphansi

I-3. Amajamo aguquguqukayo: Amandla okugcwalisa izikhala kuvumela ukubopha ukujoyina ukwakheka nokucushwa okuzoba yinselele ukuwela.

4. Ukumelana nokugqwala: Ama-alloy amaningi abhidlikayo ahlinzeka ngokumelana kahle nokugqwala, abenze balungele izinhlelo zezimboni.

Izinzuzo ze-Fusion Welding:

1. Amandla aphezulu: I-Fusion Welding yakha amalunga anamandla amakhulu afanele izinhlelo zokusebenza ezihlelekile kanye nezimo ezisindayo zomthwalo.

2

I-3. Izinto ezitholakala kalula: Izinsimbi eziningi zingahle zibe nokuhlanganiswa kalula - izinsimbi, futhi izinto zokuhlunga zivame ukulinganisa, zibenza batholakale kalula.

Izinja

Zombili izikejana zokubopha izicelo zokufaka izicelo zithola izicelo ezimbonini eziningi, kepha zivame ukugqama ezindaweni ezithile.

Izicelo ze-Brazing: I-Brazing isetshenziswa kakhulu ku-elekthronikhi, amapayipi, amasistimu we-HVAC, kanye nokukhiqiza izimoto, ikakhulukazi lapho izinsimbi ezingafani zidinga ukujoyinwa. Isibonelo, kuvame ukuqashwa ukuhlanganisa ukushintshaniswa kokushisa kanye nezakhi zeqandisini.

Izicelo ze-Fusion Welding: Ukufakwa kwe-fusion welding kugcwele ezimbonini ezisindayo njengokukhiwa, okwakha umkhumbi, kanye ne-aerospace, lapho amandla nobuqotho bezinhlangothi kubaluleke kakhulu. Isetshenziselwa kabanzi ukwabiwa kwensimbi yensimbi, amapayipi, kanye nezinto zemishini.

Ukugcina

Ngamafuphi, ngenkathi i-brazing ne-fusion welding zombili ziyizindlela ezibalulekile zokujoyina izinsimbi, zihlukile kakhulu ezinqubweni zazo, amazinga okushisa, ukusetshenziswa kanye nezimpawu ezihlangene. I-Brazing iyinqubo yokushisa ephansi evumela ukujoyina izinsimbi ezingafani futhi ukunciphisa ukuhlanekezela okushisayo, ngenkathi ukufudumala i-welding kunikeza amandla aphezulu, amalunga angenamthungo alungele izinhlelo zokusebenza ezisindayo. Ukuqonda lo mehluko kusiza onjiniyela kanye nabakhiqizi bakhethe indlela efanele yezidingo zabo ezithile, beqinisekisa ubuqotho kanye nokwethembeka kwemikhiqizo yabo. Inqubo ngayinye inendawo yayo ezweni lokukhiqiza, inikela ekuhlanganyeleni emikhakheni ehlukahlukene.
