Kodi Submerged Arc Welding (SAW) ndi chiyani?

Kuwotcherera kwa arc (SAW), monga momwe dzinalo likusonyezera, kumachitidwa pansi pa chinsalu chotetezera kapena bulangeti la flux.Monga arc nthawi zonse imaphimbidwa ndi makulidwe a flux, imachotsa ma radiation aliwonse omwe amawonekera komanso kufunikira kwa zowonera.Ndi mitundu iwiri ya ndondomeko, basi ndi theka-zokha, ndi mmodzi wa ambiri ntchito kuwotcherera ndondomeko ntchito makampani ndondomeko.Wenzhou Tianyu Electronic Co., Ltd., imodzi mwazinthu zodziwika bwino za waya zowotcherera za arc ku China, zikuwonetsa mfundo ndikugwiritsa ntchito kuwotcherera kwa sub-arc.Tiyeni tiwone zomwe iwo ali:

Njira:

Mogwirizana ndi kuwotcherera kwa MIG, SAW imagwiritsanso ntchito njira yopangira arc pakati pa cholumikizira cholumikizira ndi waya wosalekeza wopanda ma elekitirodi.Chingwe chopyapyala cha flux ndi slag chimagwiritsidwa ntchito kupanga zosakaniza zoteteza gasi ndikuwonjezera ma alloys ofunikira padziwe la weld, motsatana.Pamene weld ikupita, waya wa electrode amamasulidwa pa mlingo womwewo wa kumwa ndipo kutulutsa kowonjezera kumayamwa kudzera mu vacuum system kuti ibwezeretsenso.Kupatula kuteteza ma radiation, zigawo za flux ndizothandiza kwambiri popewa kutentha.Kutentha kwabwino kwa njirayi, pafupifupi 60%, kumabwera chifukwa cha zigawo izi.Komanso njira ya SAW ndiyopanda kutayira ndipo sikutanthauza njira iliyonse yochotsera utsi.

Njira yogwiritsira ntchito:

Mofanana ndi njira ina iliyonse yowotcherera, ubwino wa ma weld okhudzana ndi kuya, mawonekedwe ndi mankhwala a chitsulo chowotcherera chomwe chimayikidwa nthawi zambiri chimayendetsedwa ndi magawo omwe amawotcherera monga panopa, arc voltage, weld wire feed rate, ndi liwiro la kuyenda.Chimodzi mwa zovuta (zowona njira zilipo kuti zithetsedwe) ndikuti wowotchera sangayang'ane pa dziwe la weld ndipo chifukwa chake ubwino wa chitsime umadalira kwambiri magawo ogwiritsira ntchito.

Njira zoyendera:

Monga tanenera kale, zimangokhala ndi magawo a ndondomeko, ndipo wowotcherera amakwaniritsa mgwirizano wa weld.Mwachitsanzo, muzochita zokha, kukula kwa waya ndi kusinthasintha komwe kumagwiritsidwa ntchito komwe kuli koyenera mtundu wamba, makulidwe azinthu, ndi kukula kwa ntchitoyo kumagwira ntchito yofunika kwambiri pakusankha kuchuluka kwa makonzedwe ndi mikanda.

Waya:

Kutengera kufunikira kwa mlingo wa deposition ndi kuthamanga kwa maulendo otsatirawa mawaya akhoza kusankhidwa

· Twin-waya

·Mawaya ambiri

· Tubular waya

·Kuwonjezera ufa wachitsulo

·Waya umodzi wokhala ndi kuwonjezera kutentha

·Waya umodzi wokhala ndi kuzizira

Flux:

Kusakaniza kwa granular kwa ma oxides a zinthu zingapo monga manganese, titaniyamu, calcium, magnesium, silicon, aluminiyamu, ndi calcium fluoride amagwiritsidwa ntchito kwambiri ngati flux mu SAW.Kawirikawiri, kuphatikiza kumasankhidwa kotero kuti kumapereka zomwe zimapangidwira makina pamene zimagwirizanitsa ndi waya wowotcherera.Tiyeneranso kukumbukira kuti mapangidwe a fluxeswa amagwira ntchito yofunika kwambiri pamagetsi a arc ogwiritsira ntchito komanso magawo apano.Kutengera kufunikira kwa kuwotcherera, makamaka mitundu iwiri ya ma fluxes, omangika ndi osakanikirana amagwiritsidwa ntchito pochita izi.

Zogwiritsa:

Njira iliyonse yowotcherera ili ndi zida zake, zomwe nthawi zambiri zimadutsana chifukwa cha kuchuluka kwachuma komanso zofunikira.

Ngakhale SAW ikhoza kugwiritsidwa ntchito bwino pamalumikizidwe onse a matako (otalika ndi ozungulira) ndi ma fillet, ili ndi zoletsa zochepa.Chifukwa cha kusungunuka kwa dziwe la weld, slag mumkhalidwe wosungunuka ndi wosanjikiza wosanjikiza, zolumikizira matako nthawi zonse zimachitika pamalo athyathyathya, ndipo kumbali ina, zolumikizira za fillet zimachitika m'malo onse - lathyathyathya, lopingasa, ndi ofukula.

Tiyenera kukumbukira kuti malinga ngati njira zoyenera ndi kusankha kwa magawo okonzekera pamodzi akuchitika, SAW ikhoza kuchitidwa bwino pazinthu zamtundu uliwonse.

Itha kuyikidwa bwino pazitsulo za kaboni, zitsulo zosapanga dzimbiri ndi zitsulo zochepa za aloyi komanso ma aloyi ochepa opanda ferrous ndi zida, malinga ndi code ya ASME yoti ma waya ndi flux agwiritsidwa ntchito.

SAW imapeza malo okhazikika m'mafakitale olemera kwambiri ndi mafakitale opangira zombo zapamadzi pazigawo zazikulu zowotcherera, mapaipi akulu akulu, ndi zombo zamakina.

Pogwiritsa ntchito kwambiri mawaya a electrode komanso mwayi wopezeka wodzipangira, SAW nthawi zonse imakhala imodzi mwazinthu zomwe zimafunidwa kwambiri pakuwotcherera pamakampani opanga zinthu.
