I-electrode iwucingo lwensimbi olunamekwe futhi ngokuvamile kufanele lwenziwe kusukela kwinto efana nezakhiwo nokwakheka kuya ensimbi eshiselwayo, futhi kunezici ezimbalwa ezingena ekukhetheni i-electrode efanele yephrojekthi yakho ethile.
Ngenkathi ama-electrode ensimbi evikelekile e-arc (SMAW) noma "induku" esetshenziswa futhi eba yingxenye ye-weld, amanye ama-electrode (njengalawo asetshenziselwa ukushisela i-TIG) awasebenziseki, okusho ukuthi awancibiliki futhi abe yingxenye yokushisela. umthungo. Ukuhlukaniswa kwe-seam, kulezi zimo, ukusetshenziswa kwe-electrode kuyadingeka.
Thina kwa-Eng-weld siyazi ukuthi ukukhetha i-electrode efanele kubalulekile ekuqineni kokushisela, ikhwalithi yokushisela, ukunciphisa isipatha nokuhlanza.
Ama-electrode e-cellulose ama-electrode okushisela ambozwe ngesheath equkethe izinto eziphilayo. Ngokuvamile cishe u-30% ngesisindo se-coating i-cellulose, kodwa kwezinye izingxenye zomhlaba i-cellulose kanye nofulawa wezinkuni kungase kwengezwe ekunambeni ukuze kuncishiswe okuqukethwe kwe-cellulose okumsulwa.
Izinhlanganisela ezihlukahlukene zezinto eziphilayo kuma-electrode zizobola ku-arc zenze i-carbon dioxide, i-carbon monoxide ne-hydrogen, konke okwandisa i-voltage ngaphakathi kwe-arc, okuholela ku-arc enamandla futhi eqinile. Ngakho, ama-electrode e-cellulose angangena afinyelele ku-70% ajule kunama-electrode ahambisanayo anesilinganiso esifanayo samanje.
Ngokuvamile ekhiqizwa nge-coating encane noma ephakathi, nakuba lokhu kukhiqiza i-slag engasuswa ngemva kokuqedwa kwenqubo yokushisela, lokhu kungabangela ukulahlekelwa okukhulu kwe-spatter. Kodwa-ke, ikhono le-welding eliphansi eliqondile kanye nekhono lokungena lale electrode lihle kakhulu ngenxa yokugcwaliswa kwegebe ku-coating.
I-electrode ephansi ye-hydrogen empeleni iyi-gas shielded arc welding (SMAW) esebenzisekayo enokuqukethwe kwamanzi okungaphansi kuka-0.6% uma kuqhathaniswa nokuqukethwe kwamanzi okungokwesiko okungu-4-6% kwama-electrode e-cellulosic.
Ngokuvamile, ama-electrode e-hydrogen aphansi njenge-E7018 rod electrode ahlinzeka abasebenzisi nge-spatter ephansi kanye ne-arc ebushelelezi, ezinzile futhi ethule. Lezi zakhiwo zenza lawa ma-electrode abe yisinqumo esihle kakhulu kubo bobabili abashisela abanolwazi nabaqalayo. Izakhiwo zalawa ma-electrode ensimbi yokugcwalisa zinikeza i-welder ngokulawula okuhle kwe-arc futhi inciphise isidingo sokuhlanza ngemuva kokushisela.
Ngokungafani namanye ama-electrode afana ne-E6010 noma i-E6011, ama-electrode e-hydrogen aphansi ahlinzeka nge-deposition ephakeme kanye namazinga okungena, okuvumela i-welder ukuthi ingeze insimbi eyengeziwe ekuhlanganyeleni nganoma yisiphi isikhathi, ukuthuthukisa amandla e-weld futhi igweme ukukhubazeka kokushisela njengokuntuleka kokungena.
Ngokuvamile, ama-electrode ensimbi athambile ahlinzeka nge-arc ethule futhi ezinzile enokungena okuphansi, okuwenza alungele ukuvala igebe elibanzi kanye nezicelo zeshidi elincanyana. Kodwa-ke, kunezinhlobo ezahlukene zama-electrode ensimbi athambile, ngalinye linezindawo ezihluke kancane futhi ngaleyo ndlela lilungele kangcono izinhlelo zokusebenza ezahlukene.
Isibonelo, ibanga le-6013 liyinhloso evamile ye-electrode yensimbi emnene enikeza ukungena okujulile ngenkathi igcina i-arc ebushelelezi futhi ezinzile. I-arc kulula ukuyivuselela, i-welding seam yinhle, i-spatter incane, i-slag kulula ukuyilawula, ifaneleka ukushisela phansi okuqondile.
I-7018 arc electrode, ngakolunye uhlangothi, i-electrode yensimbi emnene eyenzelwe ukushisela izinto zensimbi ye-carbon ephezulu. Le electrode ivame ukusetshenziselwa ukushisela kwesakhiwo ngenxa yokumelana nokuqhekeka kwe-weld. Kodwa lokhu kudala i-slag eningi, engafanele ukushisela phansi okuqondile.
I-electrode yensimbi yokugcina emnene esizoyibona ingu-6011. Le electrode yokungena ejulile enemisebenzi eminingi inikeza i-arc ebushelelezi futhi ezinzile lapho sishisela insimbi ethambile ethambile nezinye izinsimbi eziphansi ze-alloy. Ukugqoka kwayo kudala i-arc enamandla yokungena okujulile, futhi ungqimba lwe-slag luncane futhi kulula ukulususa.
Njengamanye ama-electrode esiwabonile ngenhla, ama-electrode ensimbi engagqwali eza ngezinhlobo eziningana, ngalinye lihluke kancane kunangaphambili.
Lapha sibheka amamaki ama-3 ahlukene ama-electrode ensimbi engagqwali, 308, 309 kanye no-316, nokuthi kufanele asetshenziswe nini.
Uma usebenzisa amabanga 301, 302, 304, 305 nama-alloys e-casting CF-3 kanye ne-CF8, lapho-ke sincoma ukuthi usebenzise i-308L, okuhlanganisa ama-electrode e-ER308LSi. Lawa ma-electrode ensimbi engagqwali alungele izinsimbi ezingenasici ze-austenitic, kodwa ezinhlelweni ezifana nokuphehla amandla, sincoma i-electrode engu-308H njengoba le electrode ephezulu yekhabhoni inikeza ukumelana okungcono kwe-creep emazingeni okushisa aphezulu.
Uma uhlanganisa insimbi emnene noma ama-alloys ensimbi ethambile kuya kunsimbi engagqwali, sebenzisa i-309L, kuhlanganise ne-ER309LSi. Okufanayo kusebenza ekuhlanganiseni izinsimbi ezingenasici ezifana ne-409 noma 304L yensimbi engagqwali. Ngaphezu kwalokhu, kufanele futhi zisetshenziselwe ukubopha izinsimbi eziyisisekelo ezingama-309.
Uma usebenzisa izinsimbi eziyisisekelo 316L kanye ne-316 kanye nokulingana kwazo okuyi-CF-8m ne-CF-3M, kufanele kusetshenziswe u-316L kuphela njengensimbi yokugcwalisa, okuhlanganisa i-ER317LSi.
Ezinye izinhlelo zokusebenza ezingu-308L zingangena esikhundleni sika-309L njengensimbi yokugcwalisa njengoba zingadingi i-molybdenum ngokungafani nezinhlelo zokusebenza ezingu-316 noma ezingu-316L ezidinga i-molybdenum ngakho awukwazi ukufaka esikhundleni se-309 ngo-316.
Njengoba sibonile ngenhla, kunezinhlobonhlobo eziningi zama-electrode atholakalayo. Ngamunye wabo unezakhiwo ezihluke kancane ngakho-ke izici ezihlukile futhi eziyingqayizivele. Lapho kwenziwa noma yimuphi umsebenzi wokulungisa nowokulungisa, kufanele kuqikelelwe ukuthi ama-electrode asetshenzisiwe anezici ezidingekayo.
Okokuqala, thola ukuthi hlobo luni lwensimbi ozobe ulungisa noma ulusevisa. Khona-ke kufanele unqume ukuthi udinga i-electrode yenhloso evamile noma i-electrode enezakhiwo ezikhethekile. Uma usunalo lonke lolu lwazi ungaqala ukuhlanganisa, uma ungasebenzisi futhi usebenzise ama-electrode angalungile i-solder yakho cishe izohluleka noma ungavele ushise insimbi osebenza ngayo.
