I-A102I-Ss E308-16I-electrode yokuwelda inika ukusebenza okugqwesileyo ekwenzeni intsimbi engagqwaliyo ebalulekileyo. Le Cr19Ni10 esetyenziswayo enekhabhoni ephantsi inoyilo olugqunywe yi-rutile oluhambelana nemithombo yamandla ye-AC kunye ne-DC, ibonelela ngokusebenza okuguquguqukayo kwiindawo zokusebenzela nakwiindawo zasentsimini. Yenzelwe ngokukodwa ukudibanisa i-06Cr19Ni10 kunye ne-06Cr18Ni11Ti stainless grades, ivelisa isinyithi esiweld esineempawu zoomatshini eziphezulu kunye nokumelana nokugqwala okuthembekileyo phakathi kwegranular.，kubalulekile ekucutshungulweni kweekhemikhali, kwizixhobo zokutya, nakwimisebenzi yokwakha apho ukuthembeka okudibeneyo kumisela ubomi benkqubo.
Ukugqwesa kweMetallurgical kuchaza ukusebenza kwe-electrode engundoqo. Ukwakheka kwe-low-carbon elawulwayo (≤0.08% C) inciphisa imvula ye-carbide ngexesha lokuwelda, igcina ukumelana nokugqwala kwindawo echaphazelekileyo bubushushu. Ukulinganisela okuchanekileyo kwe-chromium (19%) kunye ne-nickel (10%) kuqinisekisa uzinzo lwe-austenitic microstructure, ngelixa iikhompawundi ze-titanium ngaphakathi kokuhamba zibonelela ngokuzinza okongezelelweyo ngokuchasene nokuziva. Olu lwakhiwo lwesayensi luqinisekisa ukumelana nokugqwala okuqhubekayo kunye noxinzelelo kumaqondo obushushu asebenzayo ukuya kuthi ga kwi-300°C, iphumelela kakhulu kwii-electrode zesiqhelo ezingenasici kwimidiya enamandla.
Iingenelo zokusebenza zahlula okuI-Ss E308-16imveliso. I-rutile flux coating ivumela ukuqaliswa kwe-arc okugudileyo kunye nokuchitheka okuncinci kunye nokususwa kwe-slag okulula. Ubuchule obuhle bokuwelda kwindawo buvumela ukusetyenziswa ngokuthe nkqo nangaphezulu ngaphandle kokuphazamisa ukubonakala kwe-bead okanye iprofayili yokungena. Ezi mpawu zilula ukuyisebenzisa zinciphisa ukudinwa komqhubi ngelixa zinyusa ukusebenza kakuhle kokubeka.–ukuguqulela ngokuthe ngqo kwixesha elifutshane leprojekthi kunye namazinga aphantsi okuhlaziya iivenkile zokuvelisa kunye namaqela okulungisa.
Ukuqinisekiswa komgangatho kudlulela ngaphaya kweenkcukacha zobugcisa. Yenziwe phantsi kwemigangatho yesatifikethi se-ISO 3581-A, ibhetshi nganye ivavanywa ngokuqatha kolawulo lwe-hydrogen olusasazekayo (<5ml/100g), isinyithi se-weld somgangatho we-radiographic, kunye nokumelana nokugqwala ngokwe-ASTM A262 Practice E. Olu qinisekiso lupheleleyo lwenza ii-electrode ze-A102 zilungele ukwenziwa kwemithambo yoxinzelelo, imibhobho yamayeza, kunye neminye imboni elawulwayo apho uxwebhu lwesatifikethi se-weld luyimfuneko.
I-A102 imisela umlinganiselo wokusetyenziswa kwezixhobo ezibalulekileyo zokudibanisa i-stainless. Ngokudibanisa ukuchaneka kwe-metallurgical, ukusebenza okulula kumqhubi, kunye nomgangatho oqinisekisiweyo, le mveliso iphucukileyoI-Ss E308-16i-electrode inika ukuthembeka okungenakuthelekiswa nanto kwi-300°Iindawo zenkonzo ze-C. Kwabenzi bezinto ababeka phambili ukuchasana nokugqwala, imveliso, kunye nokuthobela imithetho, imele ukhetho oluchanekileyo kwizinto ezisetyenziswayo zentsimbi engagqwali.
