Ingenabalaumnatha wentsimbi weldingine-anti-corrosion enamandla kunye ne-anti-oxidation iimpawu.Isetyenziselwa ukukhuselwa koomatshini, ishishini, ezolimo, ulwakhiwo, njl njl. Ukukhetha intsimbi yentsimbi yensimbi engenasici yomgangatho ophezulu wentsimbi yentsimbi, ngokuchaneka kokuchaneka komatshini wokuwelda, umphezulu wemveliso womnatha ogudileyo, ulwakhiwo oluqinileyo, ingqibelelo eyomeleleyo, kunye nokumelana nomhlwa okuqinileyo.
Uvavanyo lwenqaku le-nitric acid ye-stainlessumnatha wentsimbi welding.Into ephawulekayo yeetyhubhu zetsimbi yentsimbi kukuxhathisa kwemvelo kokubola kokugxila kunye nokuhlambulula i-nitric acid.Le propati ivumela ukuba yahluke ngokulula kwezinye iintsimbi okanye i-alloys.Nangona kunjalo, i-carbon 420 ephezulu kunye ne-440 steels i-corrored kancinane kuvavanyo lwe-nitric acid point, kwaye iintsimbi ezingenayo i-ferrous ziya kugqwala ngokukhawuleza xa zidibana ne-nitric acid.Ukuhlambulula i-nitric acid yonakalisa kakhulu intsimbi ye-carbon.
Uvavanyo lwe-asidi ye-sulfuric ukuntywiliselwa kwintsimbi yentsimbi engenamnatha.Olu vavanyo lusetyenziselwa ukwahlula i-302 kunye ne-304 ukusuka kwi-316 kunye ne-317. Umphetho osikiweyo wesampuli ngumhlaba omhle kwaye emva koko ufakwe kwi-nitric acid kunye nomthamo we-20-30% kunye nobushushu be-60-66.℃ukuhlamba kunye nokugqithisa isiqingatha seyure.I-sulfuric acid test solvent kunye ne-volume concentration ye-10% ishushu kwi-71℃.Xa i-302 kunye ne-304 ingena kuqala kwesi sisombululo, i-corrod ngokukhawuleza kwaye ivelise iisampulu ezinamacandelo awaziwayo ngokuthelekisa ukulinganisa.Ngale ndlela, uvavanyo lunokuchaneka ngakumbi.
Uvavanyo lwendawo ye-Copper sulfate ye-stainlessumnatha wentsimbi welding.Uvavanyo lwe-copper sulfate point yeyona ndlela ilula kwaye ilula kakhulu yokwahlula ngokukhawuleza iintsimbi zekhabhoni eziqhelekileyo kuzo zonke iintlobo zeentsimbi ezingenasici.Ukuxinwa kwesisombululo se-sulfate yethusi esetyenzisiweyo yi-5 ~ 10%.Ngaphambi kovavanyo lwamanqaku, indawo yovavanyo kufuneka icocwe ngokucokisekileyo kwigrisi okanye ukungcola okwahlukeneyo, kwaye indawo encinci kufuneka ipoliswe ngelaphu elithambileyo, emva koko ibhotile yokulahla kufuneka isetyenziswe ukuwisa isisombululo se-copper sulfate kwindawo ecociweyo.Intsimbi yekhabhoni eqhelekileyo okanye intsimbi yenza umaleko womphezulu wobhedu kwisithuba semizuzwana, ngelixa umphezulu wensimbi engenasici awubeki ubhedu okanye ubonise umbala wobhedu.
