Iziphene zeWeld:iziphene weld zinzulu, manual mechanical processing processing indlela isetyenziselwa imbuyekezo, okubangela iimpawu zokusila, okubangela umphezulu ongalinganiyo, kuchaphazela inkangeleko.
Umphezulu ongangqinelaniyo:kuphela pickling kunye passivation weld kuya kubangela umphezulu ongalinganiyo kwaye kuchaphazela imbonakalo.
Kunzima ukususa imikrwelo:I-pickling passivation jikelele, ayikwazi ukuqhutyelwa kwinkqubo yazo zonke iintlobo zemikrwelo isuswe, kwaye ayikwazi ukususa ngenxa yokukrala, i-welding splashes kunye nokunamathela kumphezulu wentsimbi ye-carbon steel stainless steel, i-splashes kunye nobunye ukungcola, okubangelwa ubukho beendaba ezidliwayo phantsi kwemeko ye-corrosion yekhemikhali okanye i-electrochemical corrosion.
Ukugulisa okungalinganiyo kunye nokunyanzeliswa:unyango pickling passivation lwenziwa emva kokupolisha manual kunye nokupholisha. Kunzima ukufezekisa isiphumo sonyango esifanayo kunye nokungaguqukiyo kwi-forgings enkulu, kwaye umphezulu ofanelekileyo awufumaneki. Kwaye iindleko zeeyure zokusebenza, izinto ezincedisayo nazo ziphezulu.

Umthamo wokuchola ulinganiselwe:i-pickling passivation paste ayikho, ukusika i-plasma, ukusika i-flame kunye ne-oxide emnyama, kunzima ukuyisusa.
Imikrwelo ebangelwa yimiba yabantu iyingozi ngakumbi:kwinkqubo yokunyuswa, ukuthutha kunye nokulungiswa kwesakhiwo, imikrwelo ebangelwa kukunkqonkqoza, ukutsala, isando kunye nezinye izinto zobuntu zinobuzaza ngakumbi, okwenza ukuba unyango lomphezulu lube nzima ngakumbi, kwaye sesona sizathu siphambili sokubola emva konyango.
Izinto zezixhobo: kwiprofayili, ukugoba ipleyiti, inkqubo yokugoba, ebangelwa yimikrwelo kunye ne-creases nayo yisona sizathu siphambili sokubola emva kwonyango.
Eminye imiba:engenabalaizixhobo zentsimbiekuthengeni, inkqubo yokugcina, ngenxa yokuphakamisa, inkqubo yokuthutha i-bump kunye nemikrwelo inzulu kakhulu, nayo enye yezizathu zokubola.
