Uma kukhulunywa ngokushisela insimbi engagqwali, ukukhethwa kwama-electrode kudlala indima ebalulekile ekunqumeni ikhwalithi nokuqina kwe-weld. Phakathi kwezinketho eziningi emakethe, i-A412izinduku zokushiselaIvelele njengokukhetha kokuqala phakathi kochwepheshe kanye nabantu abathanda izinto zokuzilibazisa ngokufanayo. I-A412 iyi-electrode yensimbi engagqwali ye-austenitic ehlanzekile ye-Cr26Ni21Mo2 ene-calcium titanium coating enikeza ukusebenza okuhle kakhulu kanye nokuguquguquka kwezinhlelo zokusebenza ezahlukahlukene zokushisela.
Idizayinelwe ukunikeza imiphumela emihle kakhulu lapho isebenza ngensimbi engagqwali, ama-electrode e-A412 ahlinzeka ngokusebenza okuhle kakhulu kokushisela kwe-AC kanye ne-DC. Ukwakheka kwayo okuyingqayizivele, okuhlanganisa nokwengezwa kwe-molybdenum ensimbini efakiwe, kuthuthukisa ukumelana kwayo nokugqwala kwemigodi, amandla okushisa kanye nokuqhekeka uma kuqhathaniswa nezinye izinketho ze-electrode ezifana ne-A402 kanye ne-A407. Lokhu kwenza i-A412 ibe ukukhetha kokuqala kwamaphrojekthi okushisela adinga amandla aphezulu nokuqina.
Enye yezinzuzo ezibalulekile zama-electrode e-A412 yikhono lawo lokunikeza imiphumela ethembekile nehambisanayo ezinhlotsheni ezahlukene zezicelo zokushisela. Kungakhathaliseki ukuthi usebenza ezingxenyeni zesakhiwo, imishini noma ukwenziwa kwensimbi engagqwali okuyinkimbinkimbi, ama-electrode e-A412 anikeza ukunemba nokuthembeka okudingayo kuma-weld asezingeni eliphezulu. Isembozo se-titanium-calcium sithuthukisa kakhulu ukuzinza kwe-arc kanye nokuhlukaniswa kwe-slag, okuqinisekisa ama-weld abushelelezi, ahlanzekile ane-spatter encane.
A412izinduku zokushiselazaziwa ngokulula kwazo ukusetshenziswa kanye nokuguquguquka kwazo. Lawa ma-electrode angasetshenziswa kokubili nemishini yokushisela ye-AC kanye ne-DC, enikeza ukuguquguquka kanye nokulula kubashiseli ezindaweni ezahlukene. Kungakhathaliseki ukuthi ungumshiseli ochwepheshe onolwazi noma ungumshiseli osafufusa, i-A412izinduku zokushiselainikeze ulwazi olusebenziseka kalula olukuvumela ukuthi ugxile emsebenzini okhona ngaphandle kokubeka engcupheni ikhwalithi yokushisela.
Ama-electrode e-A412 amelela ikhambi eliphelele lokushisela insimbi engagqwali, enikeza ukusebenza okungenakuqhathaniswa, ukuqina kanye nokuguquguquka. Ngokwakheka kwawo okuhlukile kanye nokwembozwa kwe-calcium titanium, ama-electrode e-A412 aklanywe ukuze ahlangabezane nezidingo zezinhlelo zokusebenza zokushisela zesimanje, eletha imiphumela emihle kakhulu kumaphrojekthi ahlukahlukene okushisela. Kungakhathaliseki ukuthi usebenza emisebenzini yokushisela yezimboni, yezentengiselwano noma yezindlu, ama-electrode e-A412 anikeza ukuthembeka nokunemba okudingekayo kuma-weld ekhwalithi, okwenza abe yinto ebalulekile kunoma yimuphi uchwepheshe wokushisela noma umthandi.
