Kodi Kuweta Arc Wodzazidwa ndi Madzi (SAW) n'chiyani?

Kuwotcherera kwa arc woviikidwa m'madzi (SAW), monga momwe dzinalo likusonyezera, kumachitika pansi pa wosanjikiza woteteza kapena bulangeti la flux. Popeza arc nthawi zonse imaphimbidwa ndi makulidwe a flux, imachotsa kuwala kulikonse kuchokera ku ma arches owonekera komanso kufunikira kwa zotchingira zowotcherera. Ndi mitundu iwiri ya njira, automatic ndi semi-automatic, ndi imodzi mwa njira zowotcherera zomwe zimagwiritsidwa ntchito kwambiri mumakampani opanga njira. Wenzhou Tianyu Electronic Co., Ltd., imodzi mwa ogulitsa mawaya odziwika bwino a arc woviikidwa m'madzi ku China, ikuwonetsa mfundo ndi kagwiritsidwe ntchito ka sub-arc welding. Tiyeni tiwone zomwe zili:

Njira:

Mofanana ndi MIG welding, SAW imagwiritsanso ntchito njira yopangira arc pakati pa weld joint ndi continuous bare electrode wire. Gawo lochepa la flux ndi slag zimagwiritsidwa ntchito popanga zosakaniza zoteteza mpweya ndikuwonjezera ma alloys ofunikira ku weld pool, motsatana. Pamene weld ikupitirira, waya wa electrode umatulutsidwa pamlingo womwewo wa kugwiritsidwa ntchito ndipo flux yochulukirapo imayamwa kudzera mu vacuum system kuti ibwezeretsedwenso. Kupatula kuteteza kuwala kwa dzuwa, flux layers imathandizanso kwambiri popewa kutaya kutentha. Kutentha kwabwino kwambiri kwa njirayi, pafupifupi 60%, kumayendetsedwa ndi flux layers izi. Komanso njira ya SAW siimatulutsa madzi ndipo siifuna njira iliyonse yochotsera utsi.

Njira yogwirira ntchito:

Mofanana ndi njira ina iliyonse yowotcherera, ubwino wa zolumikizira zowotcherera zokhudzana ndi kuya kwa kulowa, mawonekedwe ndi kapangidwe ka mankhwala a chitsulo chowotcherera chomwe chayikidwa nthawi zambiri zimayendetsedwa ndi magawo a kuwotcherera monga mphamvu yamagetsi, mphamvu ya arc, kuchuluka kwa waya wowotcherera, ndi liwiro la kuyenda kwa wowotcherera. Chimodzi mwa zovuta (ndithudi njira zilipo zothanirana nazo) ndikuti wowotcherera sangathe kuyang'ana dziwe lowotcherera motero ubwino wa chitsime umadalira kwathunthu magawo ogwirira ntchito.

Magawo a ndondomeko:

Monga tanenera kale, zimangochitika ndi magawo a njira, ndipo wowotcherera amawongolera bwino cholumikizira chowotcherera. Mwachitsanzo, mu njira yodziyimira yokha, kukula kwa waya ndi kusuntha komwe kumagwiritsidwa ntchito komwe kuli koyenera mtundu wamba, makulidwe a zinthu, ndi kukula kwa ntchitoyo kumachita gawo lofunikira pakusankha kuchuluka kwa malo ndi mawonekedwe a mikanda.

Waya:

Kutengera ndi kufunika kwa kuchuluka kwa malo osungiramo katundu ndi liwiro loyendera, mawaya otsatirawa akhoza kusankhidwa

· Waya wawiri

· Mawaya ambiri

· Waya wa Tubular

·Kuwonjezera ufa wachitsulo

· Waya umodzi wokhala ndi chowonjezera chotentha

· Waya umodzi wokhala ndi chowonjezera chozizira

Kusintha kwa kutentha:

Kusakaniza kwa granular kwa ma oxides a zinthu zingapo monga manganese, titaniyamu, calcium, magnesium, silicon, aluminium, ndi calcium fluoride kumagwiritsidwa ntchito kwambiri ngati flux mu SAW. Nthawi zambiri, kuphatikiza kumeneku kumasankhidwa kotero kuti kumapereka mawonekedwe amakina omwe amafunidwa akaphatikizidwa ndi waya wowotcherera. Tiyeneranso kudziwa kuti kapangidwe ka ma fluxes awa kamakhala ndi gawo lofunikira pamagetsi ogwirira ntchito ndi magawo amagetsi. Kutengera ndi zofunikira pakuwotcherera, makamaka mitundu iwiri ya ma fluxes, olumikizidwa ndi osakanikirana amagwiritsidwa ntchito panthawiyi.

Ntchito:

Njira iliyonse yowotcherera imakhala ndi ntchito zake, zomwe nthawi zambiri zimafanana chifukwa cha kuchuluka kwa ndalama zomwe zimagwiritsidwa ntchito komanso mtundu wake.

Ngakhale kuti SAW ingagwiritsidwe ntchito bwino kwambiri pa malo olumikizirana mafupa (aatali komanso ozungulira) komanso malo olumikizirana mafupa, ili ndi zoletsa zochepa. Chifukwa cha kusinthasintha kwa dziwe losungunula, slag yomwe yasungunuka komanso kusayenda bwino kwa madzi, malo olumikizirana mafupa nthawi zonse amachitidwa pamalo osalala, ndipo kumbali ina, malo olumikizira mafupa amachitidwa m'malo onse - athyathyathya, opingasa, komanso oimirira.

Tiyenera kudziwa kuti bola ngati njira zoyenera komanso kusankha magawo okonzekera majoini akuchitika, SAW ikhoza kuchitidwa bwino pazinthu zilizonse zokhuthala.

Itha kugwiritsidwa ntchito bwino kwambiri pa zitsulo za kaboni, zitsulo zosapanga dzimbiri ndi zitsulo zopanda aloyi ambiri komanso ma aloyi ndi zinthu zochepa zopanda chitsulo, bola ngati ASME code ikuwonetsa kuti waya ndi flux zimagwiritsidwa ntchito.

SAW imapeza malo okhazikika m'mafakitale olemera a makina ndi mafakitale omanga zombo za zigawo zazikulu zowotcherera, mapaipi akuluakulu, ndi zombo zoyendetsera ntchito.

Popeza waya wa electrode umagwiritsidwa ntchito kwambiri komanso njira zodzipangira zokha zomwe zingagwiritsidwe ntchito mosavuta, SAW nthawi zonse ndi imodzi mwa njira zowotcherera zomwe zimafunidwa kwambiri mumakampani opanga zinthu.
