Ukusebenza kanye nobuqotho bezakhiwo ezihlanganisiwe ezindaweni ezidinga kakhulu kuncike kakhulu ekukhetheni izinsimbi zokugcwalisa ezifanele. Ukuze kuhlanganiswe ama-alloy ensimbi engagqwali asezingeni lokushisa eliphezulu futhi amelana nokugqwala, ukukhetha okuthileI-Alloys Electrodes Welding Rodkubalulekile. Isigaba se-AWS A5.4 E310-16 simelela izinga eliphezulu le-electrode yokushisela yensimbi engagqwali eyenzelwe ukuletha ukushisela okuthembekile nokuqinile kwezinhlelo zokusebenza eziningi eziyinselele.
Le nduku ethize ye-Alloys Electrodes Welding, eyaziwa nangokuthi i-A402, iyi-electrode yensimbi engagqwali ye-austenitic emsulwa ye-chromium26-nickel21 ene-titania-calcium coating. Ukwakheka kwamakhemikhali kwenduku kuyisisekelo ekusebenzeni kwayo, kunikeza ukumelana okumangalisayo nokugqwala emazingeni okushisa aphezulu, ngokuvamile afinyelela ku-2100°F (1150)°C). Okuqukethwe okuphezulu kwe-alloy yentambo eyinhloko kuqinisekisa ukuthi insimbi yokushisela egciniwe igcina isakhiwo sayo kanye nezakhiwo zayo ngaphansi kokucindezeleka kokushisa.
Isici esiyinhloko salokhuI-Alloys Electrodes Welding Rodizici zayo zokumboza nokusebenza. I-titanium-calcium coating yenza kube lula ukushaya i-arc, ukushisa kwe-arc okuzinzile, kanye nokuchitheka okuncane, okuholela ekubukekeni kobuhlalu obubushelelezi, obuhle ngobuhle. I-electrode inikeza ukusebenza okuhle kakhulu ekushiseni okubekwe kuzo zonke izindawo, kufaka phakathi okuqondile kanye nokuphezulu, okunikeza ukuguquguquka okukhulu ngesikhathi sokukhiqiza nokulungisa. I-slag ngokuvamile iyaziphakamisa futhi kulula ukuyisusa, okuthuthukisa ukusebenza kahle kokushisisa.
Ukusetshenziswa okuyinhloko kwe-electrode ye-E310-16 ukushisela kwezinsimbi zohlobo lwe-25Cr-20Ni ezingashisi, njenge-HK40 kanye ne-310S. Isetshenziswa kakhulu ekwakhiweni nasekugcinweni kwezingxenye zokushisa okuphezulu, okuhlanganisa izingxenye zesithando somlilo, amashubhu okulungisa, kanye neminye imishini ye-pyrolysis. Le nduku yokushisela yama-electrode e-alloy ivame ukukhethwa ukuze ishisele phakathi kwamazinga ahlukene ensimbi engagqwali noma ezindaweni ezimbozayo ezidinga ukumelana nokushisa okuphezulu.
Ukuhlukaniswa kwe-AWS A5.4 E310-16 kuchaza ukusebenza okuphezuluI-Alloys Electrodes Welding Rodkubalulekile ezimbonini lapho ukuzinza kokushisa kanye nokumelana nokugqwala kubaluleke kakhulu. Ukusebenza kwayo okuqhubekayo kwe-arc kanye nezakhiwo zayo zensimbi ezisebenza kahle kakhulu kwenza kube ukukhetha okuthembekile kokuqinisekisa ukuhlala isikhathi eside nokuphepha kwezimpahla ezibalulekile ezishisa kakhulu. Ukusetshenziswa okufanele kwalokhu kushiswa okukhethekile okudliwayo kuyitshe lesisekelo lokwenziwa kwekhwalithi emikhakheni ye-petrochemical kanye nokukhiqizwa kwamandla.
