Submerged arc vuam (SAW), raws li lub npe qhia, yog ua nyob rau hauv qab ib tug tiv thaiv txheej los yog daim pam ntawm flux.Raws li lub arc yog ib txwm them los ntawm lub thickness ntawm flux, nws eradicates tej hluav taws xob los ntawm cov arches raug thiab tseem yuav tsum tau ntawm vuam cov ntxaij vab tshaus.Nrog ob qhov sib txawv ntawm cov txheej txheem, tsis siv neeg thiab semi-automatic, yog ib qho ntawm cov txheej txheem vuam siv dav siv hauv cov txheej txheem kev lag luam.Wenzhou Tianyu Electronic Co., Ltd., yog ib lub npe nrov submerged arc vuam hlau lwm tus neeg nyob hauv Suav teb, qhia txog lub hauv paus ntsiab lus thiab kev siv ntawm sub-arc welding.Cia peb saib lawv yog dab tsi:
Txheej txheem:
Akin rau MIG welding, SAW kuj siv cov txheej txheem ntawm kev tsim cov arc ntawm qhov sib koom ua ke thiab cov hlau tsis muaj hluav taws xob txuas ntxiv.Ib txheej nyias ntawm flux thiab slag yog siv los tsim cov roj sib xyaw tiv thaiv thiab ntxiv cov alloys uas yuav tsum tau ua rau lub pas dej ua ke, feem.Raws li cov vuam txuas ntxiv, cov hlau electrode raug tso tawm ntawm tib tus nqi ntawm kev noj thiab cov dej ntau dhau yog nqus tawm los ntawm lub tshuab nqus tsev rau kev rov ua dua tshiab.Sib nrug los ntawm kev tiv thaiv hluav taws xob, cov khaubncaws sab nraud povtseg kuj tseem muaj txiaj ntsig zoo hauv kev zam kom tsis txhob muaj cua sov.Qhov zoo tshaj plaws thermal efficiency ntawm cov txheej txheem no, nyob ib ncig ntawm 60%, yog ntaus nqi rau cov flux txheej.Tsis tas li ntawd SAW txheej txheem yog kiag li dawb ntawm spattering thiab tsis tas yuav muaj fume extraction txheej txheem.
Cov txheej txheem ua haujlwm:
Zoo ib yam li lwm cov txheej txheem vuam, qhov zoo ntawm cov pob qij txha ntawm qhov tob tob, cov duab thiab cov tshuaj muaj pes tsawg leeg ntawm cov hlau tso rau hauv vuam feem ntau yog tswj los ntawm cov vuam tsis xws li tam sim no, arc voltage, weld hlau pub tus nqi, thiab vuam mus ncig ceev.Ib qho ntawm qhov tsis zoo (txog txoj hauv kev yog muaj los tiv thaiv lawv) yog tias cov welder tsis tuaj yeem saib ntawm lub pas dej da dej thiab yog li qhov zoo ntawm qhov dej yog nyob ntawm qhov kev ua haujlwm tsis zoo.
Txheej txheem parameter:
Raws li tau hais ua ntej, nws tsuas yog nrog cov txheej txheem tsis ua haujlwm, thiab tus welder ua tiav qhov sib koom ua ke.Piv txwv li, nyob rau hauv ib tug automated txheej txheem, cov hlau loj thiab flux uas ua hauj lwm uas haum rau cov hom, thickness ntawm cov ntaub ntawv, thiab qhov luaj li cas ntawm txoj hauj lwm plays lub luag hauj lwm tseem ceeb nyob rau hauv kev txiav txim siab tus nqi deposition thiab hlaws daim duab.
Hlau:
Raws li qhov yuav tsum tau muaj ntawm qhov tso nyiaj tso nyiaj thiab kev mus ncig ceev hauv qab cov xov hlau tuaj yeem xaiv
· Twin-wire
· Ntau cov xov hlau
· Tubular hlau
· Hlau hmoov ntxiv
· Ib qho hlau nrog kub ntxiv
· Ib txoj hlua nrog txias ntxiv
Flux:
Kev sib xyaw ntawm cov oxides ntawm ntau lub ntsiab lus xws li manganese, titanium, calcium, magnesium, silicon, aluminium, thiab calcium fluoride yog dav siv los ua flux hauv SAW.Feem ntau, kev sib xyaw ua ke raug xaiv xws li nws muab cov khoom siv kho tshuab thaum nws ua ke nrog cov vuam hlau.Nws tseem yuav tsum tau muab sau tseg tias muaj pes tsawg leeg ntawm cov fluxes plays lub luag haujlwm tseem ceeb hauv kev khiav hauj lwm arc voltage thiab tam sim no tsis.Raws li qhov yuav tsum tau vuam, feem ntau yog ob hom fluxes, sib txuas thiab fused yog ua haujlwm hauv cov txheej txheem.
Kev siv:
Txhua txoj kev vuam muaj nws tus kheej cov ntawv thov, uas feem ntau sib tshooj vim qhov ntsuas ntawm kev lag luam thiab kev xav tau zoo.
Txawm hais tias SAW tuaj yeem ua haujlwm zoo rau ob lub pob qij txha (ntev thiab ncig) thiab cov pob qij txha, nws muaj qee qhov kev txwv me.Vim lub fluidity ntawm lub pas dej weld, slag nyob rau hauv lub molten lub xeev thiab ib tug xoob txheej ntawm flux, pob tw pob qij txha yeej ib txwm nqa tawm nyob rau hauv lub tiaj tus, thiab ntawm qhov tod tes, fillet pob qij txha yog ua nyob rau hauv txhua txoj hauj lwm - tiaj, kab rov tav, thiab ntsug.
Nws yuav tsum raug sau tseg tias ntev npaum li cov txheej txheem tsim nyog thiab xaiv cov kev txwv rau kev npaj sib koom ua ke tau ua tiav, SAW tuaj yeem ua tiav rau cov khoom siv ntawm txhua qhov tuab.
Nws tuaj yeem siv tau zoo heev rau cov pa roj carbon steel, stainless hlau thiab cov hlau tsis tshua muaj hlau thiab tseem muaj ob peb cov hlau tsis muaj hlau thiab cov ntaub ntawv, muab ASME code qhia kev sib txuas ntawm cov hlau thiab flux.
SAW pom qhov chaw ruaj khov hauv kev lag luam tshuab hnyav thiab kev lag luam shipbuilding rau cov khoom siv vuam ntau, cov kav dej loj, thiab cov txheej txheem nkoj.
Nrog rau kev siv siab heev ntawm electrode hlau thiab siv tau automation possibilities, SAW yog ib qho ntawm feem ntau nrhiav tom qab vuam txheej txheem hauv kev lag luam tsim.
