Ngokuvamile, ukwakheka kwento eyodwa yensimbi emsulwa akulula ukugqwala. Insimbi eyenziwe ngensimbi emoyeni onomswakama ithambekele ekugqwayineni kokugqwala; kanye nocezu lwensimbi emsulwa noma ngabe lubekwe emanzini ngeke kugcwale. I-Welding yensimbi engagqwali, ihlukaniswe yinduku ye-welding, ingeyokwelashwa kokushisa, okuholele entweni yensimbi akuyona into emsulwa, uhlangane nomswakama nomoya-mpilo emoyeni, kulula ukugqwala.
Indlela yeUkusebenza kwensimbi engenasicinayo izohola ekugqekelweni kwensimbi engenasici. Uma ishidi lensimbi ligoqwa futhi lalungiswa ngokungqongqoza, indawo ye-crease futhi kulula ukugqwala.
Ukubusheleleka kwensimbi yensimbi kanye nosayizi wamathuba okugqwala nawo unobudlelwano obuthile. Ingaphezulu lensimbi ebushelelezi akulula ukugqwala, kanti indawo enolaka yensimbi kungenzeka kakhulu ukugqwala. Ukushisa ngokweqile kwensimbi yensimbi noma izinga lokushisa elingaphezulu likhuphuka ngenxa yesando nokucutshungulwa kwangaphandle, futhi kungenye yezizathu zokugqwala komhlaba wensimbi.
Uhlelo lokugqwala lwensimbi olungenasici
1. I-Surface Polishing. Ubulukhuni bensimbi engagqwali futhi ingaphezulu lingaba namabala asolwandle, kuzosheshisa i-oxidation of rust ngaphandle kwe-weld. Uma i-weless yensimbi engagqwali ye-electrolysis noma ukugaya nokuphoqelela, ingathuthukisa ukumelana nokuphikiswa kwe-oxidation, ngoba incane ubulukhuni bensimbi yensimbi, ngcono ukumelana nokugqwala. Ngoba ingaphezulu elibunjiwe lensimbi engenasici lingakhiqiza ungqimba lwefilimu eliminyene, elinomfaniswano we-oxide oxide, ukuvikela insimbi yangaphakathi ukunciphisa amathuba okugqwala oxidative.
2. Ukuthatha izintambo zokwelashwa. Inhloso yokukhahlela ukuhlanza i-acides yensimbi engenasici, bese ukhiqiza ungqimba lwefilimu eliminyene lokudlula endaweni yensimbi, wandise ubuso bekhono lokuvimbela ukugqwala kanye ne-oxidation.
