1. Zvikamu zvakagadziriswa uye zvigadzirwa zvakapedzwa hazvizoraswa kunze kusvikira zvagamuchirwa neruzivo.

2. Mabhururu ari pamusoro pekunze kwewelded simbi pombi, welding ganda, welding knobs, spatters, guruva uye chikero, nezvimwewo zvinofanira kucheneswa tisati tabvisa ngura, uye loose oxide scale uye gobvu rust layer inofanira kubviswa panguva imwe chete.

3. Kana pane mafuta nemafuta pamusoro pepipe yesimbi yakashongedzwa, inofanira kucheneswa isati yabviswa ngura.Kana pane mavara emafuta uye girisi pane chikamu chenzvimbo chete, nzira dzekurasa dzisina kukwana dzinowanzosarudzwa;kana pane nzvimbo huru kana nzvimbo dzose, unogona kusarudza solvent kana inopisa alkali yekuchenesa.

4. Kana pane maasidhi, alkali, uye munyu pamusoro pepombi yesimbi yakashongedzwa, unogona kusarudza kuigeza nemvura inopisa kana kuti steam.Zvisinei, kutarisirwa kunofanira kubhadharwa pakuraswa kwemvura yakasviba, iyo isingagoni kukonzera kusvibiswa kwezvakatipoteredza.

5. Mamwe mapombi esimbi achangobva kukungurutswa akaputirwa nependi yekurapa kuitira kuti adzivise ngura panguva yenguva pfupi yekuchengetedza uye yekufambisa.Mapaipi esimbi asina tsvina akaputirwa nependi yekurapa acharaswa zvinoenderana nemamiriro chaiwo.Kana pendi yekurapa iri yezvikamu zviviri zvakaporeswa neanorapa, uye kupfeka kwacho kwakanyatso kurongeka, kunogona kurapwa nemucheka we emery, simbi isina tsvina yechubhu velvet kana kuputika kwechiedza, uye guruva rinogona kubviswa, uyezve rinotevera. danho rekuvaka .

6. Iyo yekuputira yekurapa primer kana yakajairwa primer yekunze kweiyo welded simbi pombi inowanzotarwa zvichienderana nechimiro chekuputira uye inotevera inotsigira pende.Chinhu chipi nechipi chisingagoni kushandiswa pakuwedzera kuvhara kana kukanganisa kusungirirwa kwechifukidzo chinotevera chinofanira kubviswa zvakakwana.
