Ukushisa kuqala kuyinqubo ebucayi emishinini yokushisela izinqe ehlanganisa ukuphakamisa izinga lokushisa lensimbi eyisisekelo ngaphambi kokuqala umsebenzi wokushisela. Ukuqonda inhloso kanye nezinzuzo zokushisa kwangaphambili kubalulekile kubashicileli nabachwepheshe embonini yokushisela. Lesi sihloko sihlola ukubaluleka kokushisisa kwangaphambili emishinini yokushisela izinqe, igqamisa indima yako ekuqinisekiseni ukushisela okuphumelelayo kanye nokukhuthaza ikhwalithi yokushisela.
- Incazelo ye-Preheating: Ukushisa kuqala kuhilela ukushisa isisekelo sensimbi ebangeni elithile lokushisa ngaphambi kokushisela. Izinga lokushisa langaphambi kokushisa linqunywa ngokusekelwe ohlotsheni lwempahla, ukujiya, ukwakheka okuhlangene, kanye nenqubo yokushisela.
- Ukuvimbela Ukuqhekeka: Enye yezinjongo eziyinhloko zokushisa kwangaphambili ukuvimbela ukuqhekeka ekuhlanganyeleni okushisela. Ukushisa kuqala kunciphisa izinga lokushisa phakathi kwendawo yokushisela kanye nesisekelo sensimbi ezungezile, kunciphisa ubungozi bokuqhekeka okubangelwa i-hydrogen kanye nokuqhekeka okubandayo.
- Ukunciphisa Ingcindezi: Ukushisa ngaphambi kwesikhathi nakho kunikeza ukukhululeka kwengcindezi kusisekelo sensimbi. Kuyasiza ekunciphiseni ukucindezeleka kwangaphakathi okubangelwa inqubo yokushisela, ukunciphisa amathuba okuhlanekezela kanye nokucindezeleka okusele ekushiselweni kokugcina.
- Ukuqina Kwe-Weld Okuthuthukisiwe: Ngokushisisa kuqala insimbi eyisisekelo, ijoyinti le-weld lithola ukuqina nokudumba okuthuthukisiwe. Lokhu kuholela kuma-welds anokumelana nomthelela ophezulu kanye nezakhiwo ezithuthukisiwe zemishini.
- Ukunciphisa I-Hydrogen Embrittlement: Ukushisa ngaphambi kwesikhathi kusiza ekwehliseni i-hydrogen embrittlement, okuyisenzakalo lapho ama-athomu e-hydrogen esakazeka ensimbi eshiselayo, okuyenza ibe brittle. Izinga lokushisa eliphakeme ngesikhathi sokushisa ngaphambili lisiza ukuphunyuka kwe-hydrogen, kunciphisa ubungozi bokuthi i-embrittlement.
- Ukungena Kwe-Weld Okungcono: Izinsiza zokushisa ngaphambili ekuzuzeni ukungena okungcono kwe-weld, ikakhulukazi ezintweni eziwugqinsi. Izinga lokushisa eliphakeme lithambisa isisekelo sensimbi, okwenza kube lula ukuthi inqubo yokushisela ingene ngokuhlanganyela.
- Ukuqinisekisa Ukuhlanganisa Okufanelekile: Ukushisa Ukushisa kukhuthaza ukuhlangana okufanele phakathi kwensimbi ye-weld kanye nesisekelo sensimbi. Lokhu kubaluleke kakhulu uma usebenza ngezinsimbi ezinengxubevange ephezulu nezinye izinto ezijwayele ukuhlangana kabi.
- Ukunciphisa Indawo Ethinteke Ukushisa (HAZ): Ukushisa kuqala kusiza ukulawula usayizi wendawo ethinteke ukushisa (HAZ) ngesikhathi sokushisela. I-HAZ encane inciphisa ingozi yezinguquko ze-metallurgical ensimbi eyisisekelo, igcina izakhiwo zayo zangempela.
Sengiphetha, ukushisa kwangaphambi kwesikhathi kudlala indima ebalulekile emishinini yokushisela izinqe ngokulungiselela isisekelo sensimbi yokushisela nokuqinisekisa ukushisela okuphumelelayo. Inqubo ivimbela ukuqhekeka, inikeza ukukhululeka kokucindezeleka, ithuthukisa ukuqina kwe-weld, inciphisa i-hydrogen embrittlement, ithuthukisa ukungena kwe-weld, ikhuthaza ukuhlanganisa okufanele, futhi inciphise indawo ethinteke ukushisa. Ngokusebenzisa ngokucophelela amasu okushisa asekelwe ekucacisweni kwezinto ezibonakalayo kanye nezinqubo zokushisela, ama-welders kanye nezingcweti bangakwazi ukufeza ama-welds wekhwalithi ephezulu ngezakhiwo eziphakeme zemishini. Ukugcizelela ukubaluleka kokushisa kwangaphambi kokushisa kunomthelela ekwenzeni ngcono ukusebenza kwe-butt welding, ukukhuthaza ukujoyina okuphephile nokuthembekile kwensimbi emisebenzini nasezimbonini ezihlukahlukene.
