Kumenya ibyibanze kuri E7018 ya hydrogène nkeya ya hydrogène electrode irashobora gufasha mugusobanukirwa uburyo bwogukora ibikorwa byabo, imikorere yabo hamwe na weld bashobora kubyara.
Gusudira ku nkoni bikomeza kuba urufunguzo rw'imirimo myinshi yo gusudira, igice kubera ko ibikoresho bikoreshwa muri porogaramu nyinshi bikomeza kwitanga muri gahunda, kandi kimwe n'abashinzwe gusudira benshi babizi neza.Ku bijyanye no gusudira inkoni, Sosiyete y'Abanyamerika yo gusudira (AWS; Miami, FL) E7018 inkoni ya electrode ni amahitamo asanzwe kuko itanga ibikoresho bya mashini na chimique bibereye mubisabwa bitandukanye, hamwe na hydrogène nkeya kugirango bifashe gukumira hydrogène iterwa no guturika .
Kumenya ibyibanze kuri E7018 hydrogène nkeya ya hydrogène electrode irashobora gufasha mugusobanukirwa imikorere yabo, imikorere, hamwe na weld.Nkibisanzwe, E7018 inkoni ya electrode itanga urwego ruto rwa spatter hamwe na arc yoroshye, itajegajega, kandi ituje.Ibiranga ibyuma byuzuza biha abashoramari gusudira kugenzura neza arc kandi bikagabanya ibikenewe nyuma yo gusukurwa - ibintu byombi byingenzi mubisabwa bisaba kwitondera neza ubuziranenge bwo gusudira no kwinjiza ubushyuhe, hamwe nibihe ntarengwa.
Izi electrode zitanga igipimo cyiza cyo kubitsa no kwinjirira neza, bivuze ko abakora gusudira bashobora kongeramo ibyuma byinshi byo gusudira mugice mugihe cyagenwe kuruta andi mashanyarazi menshi ya electrode (nka E6010 cyangwa E6011), kandi birashobora gukomeza kwirinda ubusembwa nko kubura fusion. .Kwiyongera kwibintu nka poro yicyuma, manganese, na silikoni kuri electrode bitanga ibyiza bitandukanye, harimo (ariko ntibigarukira gusa) kubushobozi bwo gusudira neza binyuze mumwanda, imyanda, cyangwa ingano.
Arc nziza itangira kandi igatangira, ifasha gukuraho ibibazo nkubushake bwo gutangira gusudira, ninyungu yinyongera ya E7018 inkoni ya electrode.Kubisubiramo byiza (gutangiza arc nanone), birakenewe kubanza kuvanaho ububiko bwa silicon ikora kumpera ya electrode.Ni ngombwa, ariko, kugenzura ibisabwa byose mbere yo gusudira, kubera ko kodegisi zimwe cyangwa inzira zitemewe guhagarika electrode yinkoni.
Nkuko byavuzwe mubyiciro byabo bya AWS, E7018 inkoni ya electrode itanga byibuze 70.000 psi yingutu (yagenwe na “70”) kandi irashobora gukoreshwa mumwanya wose wo gusudira (wagenwe na “1”)."8" bivuga igipimo cya hydrogène nkeya, kimwe no kwinjira hagati ya electrode itanga nubwoko bugezweho busaba gukora.Hamwe na AWS isanzwe ishyirwa mubikorwa, E7018 inkoni ya electrode irashobora kugira ibishushanyo mbonera nka "H4" na "H8" bivuga ubwinshi bwa hydrogène ikwirakwizwa ya hydrogène yuzuza ibyuma muri weld.Urugero rwa H4, kurugero, rwerekana ububiko bwa weld bufite ml 4 cyangwa munsi ya hydrogène ikwirakwizwa kuri g 100 yicyuma.
Electrode hamwe nuwashizeho “R” - nka E7018 H4R - yakorewe ibizamini byihariye kandi byafashwe nkuwabikora.Kugirango ubone iri zina, ibicuruzwa bigomba kurwanya ubushuhe mugihe runaka nyuma yo guhura nubushyuhe bwa deg deg 80 na 80% ugereranije nubushuhe bwamasaha icyenda.
Ubwanyuma, gukoresha "-1" kumurongo wa electrode (urugero E7018-1) bivuze ko ibicuruzwa bitanga imbaraga zingirakamaro kugirango bifashe kurwanya gucika mubikorwa bikomeye cyangwa mubushyuhe buke.
E7018 amashanyarazi make ya hydrogène electrode irashobora gukorana numuyoboro uhoraho (CC) utanga amashanyarazi asimburana (AC) cyangwa amashanyarazi meza (DCEP).E7018 ibyuma byuzuza bifite arc stabilisateur ya arc hamwe na / cyangwa ifu yicyuma mugipfundikizo kugirango ifashe kugumana arc ihamye mugihe cyo gusudira ukoresheje amashanyarazi ya AC.Inyungu yibanze yo gukoresha AC hamwe na electrode ya E7018 nugukuraho arc ya arc, ishobora kubaho mugihe DC yo gusudira ukoresheje ibitari byiza-byiza cyangwa mugihe cyo gusudira ibice bya magneti.Nubwo ufite arc stabilisateur yinyongera, gusudira bikozwe ukoresheje AC ntibishobora kuba byiza nkibyakozwe na DC, ariko, kubera impinduka zikomeje mubyerekezo bigezweho bigera inshuro 120 kumasegonda.
Iyo gusudira hamwe numuyoboro wa DCEP, izo electrode zirashobora gutanga uburyo bworoshye bwo kugenzura arc hamwe nisaro ryiza cyane ryo gusudira, kubera ko icyerekezo cyimyuka ihoraho.Kubisubizo byiza, kurikiza ibyifuzo byabashinzwe gukora ibipimo bya diameter ya electrode.
Kimwe nuburyo ubwo aribwo bwose na electrode, tekinike ikwiye mugihe cyo gusudira inkoni hamwe na E7018 inkoni ya electrode ni ngombwa kugirango ubuziranenge bwiza bwo gusudira.Fata uburebure bwa arc - nibyiza kubika electrode hejuru yicyuzi cya weld - kugirango ugumane arc ihamye kandi ugabanye amahirwe yo kwikunda.
Mugihe cyo gusudira mumwanya uringaniye kandi utambitse, point / gukurura electrode 5 deg kugeza kuri 15 deg kure yicyerekezo cyurugendo kugirango bifashe kugabanya amahirwe yo gufata umutego muri weld.Mugihe cyo gusudira muburyo bwa vertical-up, point / gusunika electrode hejuru ya 3 deg kugeza kuri 5 deg mugihe ugenda hejuru, hanyuma ukoreshe tekinike yo kuboha kugirango ifashe kubuza gusudira kugabanuka.Ubugari bw'amasaro yo gusudira bugomba kuba inshuro ebyiri nigice z'umurambararo wa insinga ya electrode yibanze ya weld ya tekinike kandi itambitse, hamwe na kabiri nigice kugeza kuri bitatu bya diameter yibanze ya vertical-up weld.
E7018 inkoni ya electrode isanzwe yoherezwa nuwabikoze mumapaki yifunze kugirango abarinde kwangirika no gufata.Ni ngombwa kugumisha iyo paki neza kandi ikabikwa ahantu hasukuye, humye kugeza ibicuruzwa byiteguye gukoreshwa.Bimaze gukingurwa, electrode yinkoni igomba gukoreshwa hamwe na gants isukuye, yumye kugirango birinde umwanda n imyanda kwizirika kuri kote no gukuraho amahirwe yo gufata amazi.Electrode nayo igomba gufatwa mu ziko ubushyuhe bwasabwe nuwabikoze nyuma yo gufungura.
Kode zimwe zerekana igihe electrode yinkoni ishobora kumara hanze yububiko bufunze cyangwa ifuru yo kubikamo kandi niba cyangwa inshuro zingahe icyuzuzo gishobora gusubirwamo (nukuvuga binyuze mugikoni kidasanzwe kugirango gikureho ubuhehere bwakiriwe) mbere yuko kijugunywa.Buri gihe ujye ubaza ibisobanuro hamwe nibisabwa kuri buri murimo.
