Makhalidwe ndi ntchito zosiyanasiyana za electrode arc kuwotcherera

Mukamagwiritsa ntchito ma elekitirodi pakuwotcherera arc, makina owotcherera omwe amafunikira ndi osavuta, ndipo mutha kusankha makina owotcherera a AC kapena DC.Kuphatikiza apo, palibe chifukwa chowonjezera zida zothandizira powotcherera, bola ngati pali zida zosavuta zothandizira.Makina owotcherera awa ndi osavuta kupanga, otsika mtengo pamtengo, komanso osavuta kuwasamalira.Chifukwa cha kuchepa kwa ndalama zogulira zida, kuwotcherera kwa electrode arc kwagwiritsidwa ntchito kwambiri popanga mafakitale.

Ukadaulo wowotcherera wa Electrode arc sikuti umangokhala ndi ntchito yodzaza zitsulo mu weldment, komanso safunikira kuyambitsa mpweya wotchingira wowonjezera pakugwiritsa ntchito.Panthawi yotentha ya arc, mphamvu yapakati pa electrode ndi weldment imapanga dziwe losungunuka, pamene electrode yokha imapanga zinthu zoyaka zomwe zimagwirizanitsa kupanga mpweya wotetezera womwe umateteza dziwe losungunuka ndi weld.Kuphatikiza apo, kapangidwe ka ndodo yowotcherera idapangidwa kuti ikhale yosagwira mphepo komanso yolimba pakukana kwa mphepo, zomwe zimapangitsa kuwotcherera kwapamwamba kwambiri pamalo amphepo.

Electrode arckuwotchereraali ndi ubwino wa ntchito yosavuta ndi lonse ntchito osiyanasiyana.Ndikoyenera kuwotcherera zinthu zingapo kapena magulu ang'onoang'ono, makamaka ma welds omwe ndi ovuta kuwotcherera ndi makina monga mawonekedwe osamvetseka ndi kutalika kwaufupi.Mukamagwiritsa ntchito ukadaulo wowotcherera ndodo, malo owotcherera sakhala ochepa, ndipo amatha kugwiritsidwa ntchito mosinthika ngakhale m'malo opapatiza kapena m'malo ovuta.Kuphatikiza apo, zida zomwe zimafunikira paukadaulo wowotcherera wa electrode arc ndizosavuta, palibe mpweya wothandiza womwe umagwiritsidwa ntchito, ndipo luso la wogwiritsa ntchito silokwera kwambiri.

The applicability wa ma elekitirodi arc kuwotcherera luso ndi lonse, ndipo ndi oyenera kuwotcherera pafupifupi zitsulo zonse muyezo ndi aloyi.Posankha elekitirodi olondola, kuwotcherera chingapezeke kwa zipangizo zosiyanasiyana, kuphatikizapo otsika aloyi chitsulo, mpweya zitsulo, mkulu aloyi zitsulo ndi zitsulo zosiyanasiyana sanali ferrous.Komanso ma elekitirodi angagwiritsidwe ntchito kuwotcherera mitundu yosiyanasiyana ya workpieces, monga zitsulo zosiyana, komanso ntchito zosiyanasiyana kuwotcherera monga kukonza kuwotcherera chitsulo chotayidwa ndi pamwamba kuwotcherera zipangizo zosiyanasiyana zitsulo.Elekitirodi yokha imatha kuperekanso kuchuluka kwa mpweya wotchinga kuti mupewe mavuto monga okosijeni wa weld.Panthawi imodzimodziyo, zitsulo zodzaza zimatha kuwonjezera mphamvu ndi kulimba kwa weld.M'madera ovuta monga mphepo yamkuntho, teknoloji yowotcherera ya electrode arc imatha kukhala ndi zotsatira zabwino, kuonetsetsa kuti ntchito zowotcherera zikuyenda bwino.

Njira yowotcherera imatsimikiziridwa molingana ndi momwe zitsulo zimapangidwira, ndipo zida zosiyanasiyana zachitsulo zimafunikira njira zowotcherera.Nthawi zambiri, chitsulo cha kaboni, chitsulo chochepa cha aloyi, chitsulo chosapanga dzimbiri, chitsulo chosagwira kutentha, mkuwa ndi ma aloyi awo amatha kuwotcherera ndi njira zowotcherera wamba.Komabe, pazinthu zina zazitsulo, monga chitsulo choponyedwa, chitsulo cholimba kwambiri ndi chitsulo cholimba, kutentha kwa preheating kapena pambuyo pa kutentha kungafunike, kapena njira zowotcherera zosakanizidwa zingagwiritsidwe ntchito.Komabe, zitsulo zotsika kwambiri zosungunuka (monga zinki, lead, malata ndi ma aloyi ake) ndi zitsulo zosasunthika (monga titaniyamu, niobium, zirconium, etc.) sizingawotchedwe pogwiritsa ntchito njira zowotcherera wamba.Choncho, musanayambe kuwotcherera, m'pofunika kufufuza mosamala ndikuwunika zinthuzo, ndikusankha teknoloji yoyenera yowotcherera ndi ndondomeko malinga ndi momwe zinthu zilili.

Zogulitsa zotere nthawi zambiri zimakhala ndi mawonekedwe ovuta komanso mawonekedwe osiyanasiyana, zomwe zimafuna ntchito zamanja ndi njira zowotcherera kuti zitsimikizire mtundu ndi kudalirika kwa kuwotcherera.Popeza njira yowotcherera imafunikira luso laukadaulo ndi chidziwitso, njira zamakina ndi zodziwikiratu sizoyenera kuzinthu zamtunduwu.Panthawi imodzimodziyo, mtundu uwu wa mankhwala nthawi zambiri umakhala ndi mtengo wapamwamba wa unit kapena gulu laling'ono lopanga, ndipo limayenera kupangidwa mwachindunji.Chifukwa chake, pamtundu uwu wazinthu, njira yabwino kwambiri yopangira ndi kuwotcherera pamanja ndi kupanga batch yaying'ono kuti zitsimikizire kuti ntchitoyo ndi yabwino komanso yabwino.Panthawi imodzimodziyo, luso lamakono ndi zochitika zimafunikanso pakuyika ndi kukonza kuti zitsimikizidwe kuti zimagwiritsidwa ntchito bwino komanso chitetezo cha mankhwala.
