Ngexesha lokuphatha, indibano, i-welding ye-welding, i-Welding Seam, izixhobo, kunye nezinto ezingcolileyo zentsimbi ezingenamabala, ukuqhekeza, iipeyinti, ipeyinti, kunye ne-slagtas. Ezi zinto zichaphazela umgangatho wensimbi engaphezulu, yonakalisa ifilimu yayo, inciphise ukunganyangeki komhlaba, kwaye ikwazi ukuthuka imithombo yeendaba ezithuthayo kwiimveliso zemichiza ezithuthwayo, kwaye inesiko lokungakhathali.
Iitanki zentsimbi ezingenasitali, ngenxa yokuthwala ezahlukeneyo iichemicals, zineemfuno eziphezulu zokuthintela ungcoliseko lwempahla. Njengomgangatho womhlaba wokuveliswa kweepleyiti zentsimbi engenamsebenzi, ihlwempuzeke kakhulu, kuyinto eqhelekileyo ukwenza umatshini, ikhemikhali, okanyeI-eleclictrolytic iPolilingKwipleyiti zentsimbi engenasimo, izixhobo, kunye nezixhobo ngaphambi kokucocwa, ukuthathwa, kunye nokuphucula ukuphucula ukunganyangeki kwentsimbi engenasigaba.
Ifilimu yokupasa kwintsimbi engenasimo ineempawu ezinamandla kwaye akufuneki ithathwe njengento ebonakalayo ukuba ikhuselwe kodwa endaweni yoko kwenziwa kokuzikhusela. Ihlala yonakaliswa phambi kokuncitshiswa kwearhente (njenge-chloride ion) kwaye inokukhusela kwaye ilungiswe kubukho bee-onudants (njengomoya).
Xa intsimbi engenasimo ivezwe ngumoya, iifom zefilimu ze-oxia.
Nangona kunjalo, le propati yokukhusela ifilimu ayonelanga. Ngokusebenzisa i-acid yokuthatha, ubukhulu be-8μm yeindawo yentsimbi engenasitayileifakwe utyala, kwaye umsebenzi wekhemikhali we-acid wenza inqanaba lokuphelisa kwiziphelo ezinesiphene elingaphezulu kweendawo ezingaphezulu. Ke ngoko, ukukhetha kwenza wonke umphezulu othambekele kwimali eseleyo. Ngokubalulekileyo, ngokuhamba kunye nokudutyulwa, intsimbi kunye ne-oxiles yayo inyibilikiswe ngokukhethekileyo i-chromium kunye ne-oxider yayo, isusa umphezulu we-chromium. Phantsi kwesenzo esidlulayo see-oxidants, ifilimu epheleleyo nelizinzileyo neyenzeka kwifilimu enesidima etyebileyo yeChromium efikelela kwi + 1.0v (S6V), ukusondela ekuzinzeni izinyithi ezibalaseleyo, ukuphucula ukuzimela kwengqondo.
