Ukuthungwa kwensimbi okungenasici

Iyacubungula insimbi engagqwali, njengezinto ezibonakalayo, inenqwaba yezici. Lokhu kusebenza nakwezingxenye ze-welding.

Ukushisa okungenalutho akuyona umsebenzi olula. Kudinga umenzi ukuba aqaphele kahle inqubo yezobuchwepheshe. Indawo yokuxhumeka kwezinsimbi kufanele ivikeleke emiphumeleni emibi yomoya emoyeni. Njengoba sesinelisekile lesi simo, sizoqinisekisa ukuthembeka kwe-welding.

Ngezindlela eziningi, ukukhishwa kwekhwalithi ephezulu ye-stainless steel kuxhomeke ekunqumeni okulungile kwemiphetho yezingxenye ezifakwe ohlangothini kanye nokulungiswa kwama-electrodes.

Ngenxa yokushisa kwezingxenye, okungukuthi, ukushisa kwabo, ifilimu ye-oxide, okumelwe isuswe kamuva. Ngokuvamile, ukukhishwa kwensimbi okungenasici kukhishwa umthombo wamanje osebenzisa ama- tungsten electrodes.

Insimbi engenasici iqukethe i-chromium, ekhishwa ngomlilo ihlanganisa isakhi samakhemikhali se-carbon ne-chromium, ephula ukuhlelwa kwensimbi futhi yandisa ukwehlukana kwayo.

Eqinisweni, lesi sizatfu siphinde saphoqelelwa ukushiswa kwe-stainless steel emvelweni wegesi ezivikelayo nokusebenzisa ukuguqulwa okukhethiwe.

Izindlela zokudonsa

Ukuxhuma izingxenye ezivela ensimbi engagqwali, noma yiluphi uhlobo lwe-welding lungasetshenziswa. Kukhona umthetho ongabonakali kule ndaba. Uma izakhi ezifakwe emagumbini zikhudlwana kunamamitha ayizigidi nengxenye, ukukhishwa kwe-arc isetshenziswa ngesandla ngamakhemikhali angenakudliwa okwenziwa nge-tungsten ekhanyayo. Le nqubo kumele yenzeke endaweni yokuvikela yanoma yimaphi amagesi angenayo. Amagesi anjalo azinzile, awasekeli ukushisa futhi awafaki imikhiqizo yokuphendula kwamakhemikhali nezinye izinto. Lapho welingisa insimbi engenasici, igesi le- inert alihlanganisi nezinsimbi zezingxenye eziphethwe.

I-tank ensimbi engenasici noma amapayipi ensimbi angenalutho angenakulinganiswa nge-arc method manual.

Ukuxhuma izakhi obuncane obungaphansi kwe-1 mm, ukudonsa okufakwe nge-pulsed electrode engasetshenzisiwe endaweni yokugesi engathathi hlangothi isetshenziswa.

Izinto zensimbi ezinobuningi obungaphansi kwezingu-0.8 mm zihlangene ne- arc kagesi ngensimbi yokudluliswa yi-jet.

Kanye nezindlela ezimbili zakudala zokucubungula insimbi engenasici echaziwe ngenhla, imvamisa ephakeme, i-laser nezinye izindlela zokwelusa zisetshenziswa kakhulu.

Indlela yokujoyina izingxenye ikhethwa ngokusekelwe kokubunjwa kwensimbi nokuqina kwayo.

Kunezinhlobo eziningi zezici ze-welding izitsha ezingenalutho. Futhi uma bengacabangi, umcibisholo ophehliwe uzoba ongalungile. Isibonelo, emva kokususa endaweni yokugcoba, kungabonakala ukubola, okubizwa ngokuthi ochwepheshe ngokuthi "ummese". Futhi uma ivuleka isikhathi eside emazingeni aphezulu okushisa, umcibisholo ungase uphuke.

Ukukhetha ngokufanele izinto zokugcwalisa kanye nobude be-arc, "ukuphahla okushisayo" kungavinjelwa.

Lapho insimbi engagqwali isiphelile, izingxenye eziphelile ziphathwa ngezinto zokuqeda, ukugaya nokuziphofa.

Ukwelashwa okushisayo kwenziwa ngaleso sikhathi . Ngesikhathi esifanayo, izingxube ezixubile ziyancibilika, futhi i-chromium isakazeka ngokulinganayo kulo lonke ucingo.

Ama-enching agents asetshenziselwa ukuhlanza umcengezi weld kusuka kokungcola kanye ne-plaque. Le nqubo ibuye iqinisekise ukuthi umcibisholo awuyikuthumba esikhathini esizayo.
