Submerged arc welding (SAW), sezvinoreva zita racho, inoitwa pasi pechidziviriro chekudzivirira kana gumbeze rekuyerera.Sezvo iyo arc inogara yakafukidzwa nehupamhi hwekuyerera, inobvisa chero radiation kubva kune akafumurwa arches uye zvakare kukosha kwewelding skrini.Iine maviri akasiyana eiyo maitiro, otomatiki uye semi-otomatiki, ndeimwe yeanonyanya kushandiswa welding process inoshandiswa muindasitiri yekugadzira.Wenzhou Tianyu Electronic Co., Ltd., mumwe wevane mukurumbira pasi pearc welding waya vatengesi muChina, inoratidza musimboti uye mashandisiro e sub-arc welding.Ngativaonei zvavari:
Maitiro:
Akin to MIG welding, SAW inoshandisawo hunyanzvi hwekugadzira arc pakati pejoinhi reweld uye inoenderera isina bare electrode waya.Iyo yakatetepa yekuyerera uye slag inoshandiswa kugadzira inodzivirira gasi musanganiswa uye kuwedzera anodiwa alloys kune weld pool, zvichiteerana.Sezvo weld ichienderera mberi, waya ye electrode inoburitswa pachiyero chimwe chekushandisa uye iyo yakawandisa flux inoyamwa kunze kuburikidza nevacuum system yekudzokorodza.Kunze kwekudzivirira radiation, flux layers zvakare inobatsira zvakanyanya mukudzivirira kurasikirwa nekupisa.Kunyanya kupisa kwekupisa kwekuita uku, kwakatenderedza 60%, kunonzi kune aya mafungu ekuyerera.Zvakare SAW process haina zvachose yekupfira uye haidi chero nzira yekubvisa utsi.
Operating procedure:
Kungofanana nedzimwe nzira dzewelding, mhando yeweld joints ine chekuita nekudzika kwekupinda, chimiro uye chimiro chemakemikari ye weld simbi yakaiswa kazhinji inodzorwa neiyo welding paramita seyazvino, arc voltage, weld wire feed rate, uye weld yekufamba kumhanya.Chimwe chezvipingamupinyi (zvechokwadi nzira dziripo kuti dzipikisane nazvo) ndeyokuti welder haigoni kutarisa pane weld pool uye naizvozvo kunaka kwetsime kunoenderana zvachose nemaitiro ekushanda.
Maitiro parameters:
Sezvambotaurwa, zvinongori nemaitiro maparamita, uye welder anokwenenzvera weld joint.Semuyenzaniso, mukuita otomatiki, saizi yewaya uye flux yakashandiswa inokodzera mhando yakajairwa, ukobvu hwezvinhu, uye saizi yebasa inoita basa rakakosha pakusarudza chiyero chekuisa uye mabead maumbirwo.
Waya:
Zvichienderana nezvinodiwa zvedeposition rate uye mafambiro ekufambisa anotevera waya anogona kusarudzwa
·Twin-waya
·Waya dzakawanda
·Tubular waya
·Metal poda kuwedzera
·Waya imwe chete ine kupisa kuwedzera
·Waya imwe chete inotonhora kuwedzera
Flux:
Musanganiswa wegranular weokisidhi yezvinhu zvakati wandei senge manganese, titanium, calcium, magnesium, silicon, aluminium, uye calcium fluoride inoshandiswa zvakanyanya sekuyerera muSAW.Kazhinji, kusanganiswa kunosarudzwa kwakadai kuti kunopa iyo inotarisirwa mechanical properties kana ichibatanidza ne welding wire.Izvo zvinofanirwa kucherechedzwa kuti kuumbwa kweaya fluxes anoita basa rakakosha mukushanda arc voltage uye ikozvino paramita.Zvichienderana nezvinodiwa zvewelding, mhando mbiri dzekuyerera, dzakasungwa uye dzakasanganiswa dzinoshandiswa mukuita.
Zvishandiso:
Imwe neimwe nzira yewelding ine yayo seti yemashandisirwo, ayo anowanzo kupindirana nekuda kwehukuru hwehupfumi uye hunhu hunodiwa.
Kunyange zvazvo SAW inogona kushandiswa zvakanaka kune ese majoini ebutt (longitudinal uye circumferential) uye majoini efillet, ine mashoma mashoma anorambidzwa.Nekuda kweiyo fluidity yedziva re weld, slag mune yakanyungudutswa uye yakasununguka layer ye flux, butt majoini anogara achiitwa munzvimbo yakati sandara, uye kune rumwe rutivi, majoini efillet anoitwa munzvimbo dzese - flat, yakatwasuka, uye vertical.
Izvo zvinofanirwa kucherechedzwa kuti chero nzira dzakakodzera uye kusarudzwa kwezviyereso zvekugadzirira majoini zvichiitwa, SAW inogona kubudirira kuitwa kune chero ukobvu hwese.
Inogona kunyatso kuisirwa kabhoni simbi, simbi isina tsvina uye yakaderera alloy simbi uye zvakare mashoma asiri-ferrous alloys uye zvinhu, chero iyo ASME kodhi yakakurudzirwa musanganiswa wewaya uye flux uchishandiswa.
SAW inowana nzvimbo yechigarire mumaindasitiri anorema emuchina uye maindasitiri ekuvaka ngarava yezvikamu zvakakura zvewelding, mapaipi makuru edhayamita, uye midziyo yekugadzira.
Nekushandiswa kwakanyanya kwewaya ye electrode uye zvinogoneka otomatiki mukana, SAW inogara iri imwe yeinonyanya kutsvakwa mushure mekuita welding muindasitiri yekugadzira.
