Ukuwelda ngentsimbi engenasiciyinkqubo ebalulekileyo kulwakhiwo lwanamhlanje, efuna izinto ezisetyenziswayo eziqinisekisa ukumelana nokugqwala kunye nokuqina kwesakhiwo. I-electrode ye-E308-16 sisixhobo esisisiseko esenzelwe ngokukodwa le njongo. Njenge-electrode egqunywe ngohlobo lwe-titanium, yenzelwe ukusetyenziswa ngeentsimbi ezingenasici ze-carbon eziphantsi kakhulu, nto leyo eyenza inxalenye ephambili kwiinkqubo ezininzi zokugcinwa kwemizi-mveliso kunye nokuveliswa. Ukuthembeka kwesakhiwo sonke esigqunywe nge-welded kudla ngokuxhomekeka ekukhetheni ngokuchanekileyo kwee-electrode ezikhethekileyo, okwenza ukuqonda iimpawu zazo kube yimfuneko kubathungi kunye neenjineli.
I-electrode ye-E308-16 yenziwe ngokweekhemikhali ukuze isetyenziswe njengesixhobo sokuqala kwi-stainless steel welding: ukudibanisa i-18% ye-chromium kunye ne-8% ye-nickel steels. Olu lwakhiwo lolunye lwezona ntlobo ziqhelekileyo ze-austenitic, kwaye i-chemistry yediphozithi ye-electrode ilungelelaniswe ngononophelo ukuze ihambelane nokumelana kwayo nokugqwala kunye neempawu zoomatshini. Igama elithi "L" kwisiseko sayo esihambelanayo sesinyithi libonisa umxholo ophantsi wekhabhoni, nto leyo ebalulekileyo ekuthinteleni ukuna kwe-carbide ngexesha lenkqubo ye-welding. Oku kuqinisekisa ukuba i-welded joint igcina ukumelana kwayo nokugqwala kwe-intergranular, indawo eqhelekileyo yokusilela kwi-stainless steel engagqwali kakuhle.
Ububanzi besicelo sale electrode kwiukuwelda ngentsimbi engagqwaliyoibanzi kakhulu, ingakumbi kwicandelo lezemizi-mveliso. Ifanelekile kakhulu ekwenzeni izakhiwo ezenziwe ngentsimbi engagqwaliyo ye-022Cr19Ni10 (eqhelekileyo yaseTshayina elingana ne-304L). Isetyenziswa kakhulu ekwenzeni izixhobo zeendawo ezinobungozi, izityalo zefayibha zokwenziwa, izixhobo zemveliso yesichumiso kunye nezixhobo ezahlukeneyo ze-petrochemical. Kwezi zicelo, ukuthembeka kwe-weld okunikezelwa yi-E308-16 kubalulekile ekuthinteleni i-corrosive media kunye nokugcina ukhuseleko lokusebenza.
Iimpawu zokusebenza ze-E308-16 zenza ukuba ibe lukhetho oluguquguqukayo kwiindawo ezahlukeneyo zokuwelda. Isimamva esithi “-16″ kudidi lwayo sibonisa ukuba ine-lame-titania coating, exhasa ukuwelda kuzo zonke iindawo.—ithe tyaba, ithe tyaba, imile nkqo, kwaye ingaphezulu. Le yinzuzo ebalulekileyo ekwenzeni nasekulungiseni intsimi apho ukutshintshwa kwenxalenye kungenzeki khona. I-arc izinzile, i-slag isuswa lula, kwaye imbonakalo yentsimbi igudileyo, nto leyo enegalelo kwimisebenzi yokuwelda yentsimbi engagqwaliyo esemgangathweni ophezulu nesebenzayo kunye nokucoca okuncinci emva kokuwelda.
I-electrode ye-E308-16 yinto esetyenziswayo eyilwe ngokuchanekileyo ejongana nemingeni ethileukuwelda ngentsimbi engagqwaliyokwiiklasi zekhabhoni eziphantsi kakhulu. Ukusetyenziswa kwayo kweekhemikhali ezichaziweyo kwiintsimbi ezili-18-8 kunye nokufaneleka kwayo kumashishini abalulekileyo afana neekhemikhali zepetrochemicals kunye nezichumisi kugxininisa ukubaluleka kwayo. Kwiingcali ezibandakanyeka ekudibaniseni intsimbi engagqwaliyo, ukukhetha i-electrode ye-E308-16 kwiiprojekthi ezifanelekileyo kubonelela ngendlela ethembekileyo yokufumana ii-welds ezihlala ixesha elide, ezingamelani nokugqwala ezihlangabezana neemfuno ezingqongqo zokusebenza kunye nokhuseleko kwizicelo zoshishino.
