The zikuchokera kuwotcherera elekitirodi

Elekitirodi yowotcherera ndi ndodo yachitsulo yomwe imasungunuka ndi kudzazidwa pamgwirizano wa ntchito yowotcherera pakuwotcherera gasi kapena kuwotcherera kwamagetsi.Zinthu za electrode nthawi zambiri zimakhala zofanana ndi zomwe zimagwiritsidwa ntchito.

Apa titha kumvetsetsa momwe ma electrode amapangidwira:

Chithunzi 1 Kapangidwe ka Tianqiao welding electrode

Elekitirodi yowotcherera ndi ma elekitirodi osungunuka okutidwa ndi zokutira kuti arc kuwotcherera ndodo.Amapangidwa ndi zokutira ndi kuwotcherera pachimake.

Chitsulo chachitsulo chomwe chimakutidwa ndi zokutira mu ndodo yowotcherera chimatchedwakuwotcherera pachimake.Pachimake chowotcherera nthawi zambiri ndi waya wachitsulo wokhala ndi kutalika kwake komanso m'mimba mwake.

Chithunzi 2 Kore ya Tianqiao kuwotcherera elekitirodi

Ntchito ziwiri za pachimake

1. Kuchititsa kuwotcherera panopa ndi kupanga arc kusintha mphamvu magetsi kutentha.

2. Chowotcherera pachokha chimasungunuka ngati chitsulo chodzaza ndi zitsulo zamadzimadzi kuti apange weld.Mukawotchera ndi electrode, chitsulo chapakati chimakhala gawo la chitsulo chonsecho.Choncho, mankhwala zikuchokera weld pachimake zimakhudza mwachindunji ubwino wa weld.Chifukwa chake, waya wachitsulo womwe umagwiritsidwa ntchito ngati pachimake cha elekitirodi uli ndi mtundu wake komanso kapangidwe kake kapadera.

Electrode zokutiraamatanthauza ❖ kuyanika wosanjikiza ntchito pamwamba pa kuwotcherera pachimake.Chophimbacho chimawonongeka ndikusungunuka mu njira yowotcherera kuti ipange gasi ndi slag, zomwe zimagwira ntchito poteteza makina, chithandizo chazitsulo, komanso kusintha kwa ntchito.

Chithunzi 3 Kupaka kwa Tianqiao welding electrode

The zikuchokera ❖ kuyanika zikuphatikizapo: mchere (monga nsangalabwi, fluorspar, etc.), ferroalloys ndi ufa zitsulo (monga ferromanganese, ferro-titaniyamu, etc.), organic zinthu (monga nkhuni ufa, mapadi, etc.), mankhwala (monga titaniyamu dioxide, madzi galasi, etc.).Kuphimba kwa electrode ndi chinthu chofunikira pozindikira mtundu wa welds.

Main ntchito ❖ kuyanika mu ndondomeko kuwotcherera

1. Sinthani kukhazikika kwa kuyaka kwa arc:

Elekitirodi yosatsekedwa sikophweka kuyatsa arc.Ngakhale utayaka, sungathe kuwotcha mokhazikika.

2. Tetezani dziwe la weld:

Panthawi yowotcherera, mpweya, nayitrogeni ndi nthunzi wamadzi mumlengalenga zimalowa mumsoko wowotcherera, womwe ungakhale ndi zotsatira zoyipa pa msoko wowotcherera.Osati mapangidwe pores, komanso kuchepetsa makina katundu wa weld, ndipo ngakhale chifukwa ming'alu.Pambuyo pakusungunuka kwa electrode, mpweya wochuluka umapangidwa kuphimba arc ndi dziwe losungunuka, zomwe zidzachepetsa kuyanjana pakati pa chitsulo chosungunuka ndi mpweya.Pamene weld itakhazikika, chophimba chosungunuka chimapanga slag, yomwe imaphimba pamwamba pa weld, imateteza chitsulo chowotcherera ndikuchizizira pang'onopang'ono, kuchepetsa kuthekera kwa porosity.

Chachitatu, kuonetsetsa kuti weld ndi deoxidized ndi desulfurized ndi phosphorous zonyansa

Ngakhale kuti chitetezo chimachitika panthawi yowotcherera, sichingalephereke kuti mpweya wochepa ulowe mu dziwe losungunuka kuti likhale ndi oxidize zitsulo ndi aloyi, kutentha zinthu za alloy, ndi kuchepetsa ubwino wa weld.Choncho, m'pofunika kuwonjezera chochepetsera (monga manganese, silicon, titaniyamu, aluminiyamu, ndi zina zotero) ku zokutira za electrode kuti muchepetse ma oxide omwe alowa mu dziwe losungunuka.

4. Onjezani zinthu zopangira ma weld:

Chifukwa cha kutentha kwapamwamba kwa arc, zinthu zopangira zitsulo za weld zidzasungunuka ndikuwotchedwa, zomwe zidzachepetsa mphamvu zamakina a weld.Choncho, m'pofunika kuwonjezera zinthu zoyenera alloying kuti weld kupyolera ❖ kuyanika kuti alipire kuwotcha kutayika kwa aloyi zinthu ndi kuonetsetsa kapena kusintha makina katundu wa weld.Pakuwotcherera zitsulo zina za aloyi, m'pofunikanso kuti alowetse aloyi mu weld kupyolera mu zokutira, kuti zitsulo zowotcherera zikhale pafupi ndi zitsulo zazitsulo zazitsulo, ndipo mphamvu zamakina zimatha kugwira kapena kupitirira. zitsulo zoyambira.

5. Kupititsa patsogolo ntchito zowotcherera ndikuchepetsa spatter:

Chophimba cha electrode chimakhala ndi zotsatira zowonjezera dontho ndi kuchepetsa spatter.Malo osungunuka a zokutira ma elekitirodi ndi otsika pang'ono kuposa kuwotcherera mfundo pachimake.Komabe, chifukwa chowotcherera chili pakatikati pa arc ndipo kutentha kumakhala kokwera kwambiri, chowotcherera chimasungunuka choyamba, ndipo zokutirazo zimasungunuka pakapita nthawi.Nthawi yomweyo, popeza kutayika kwachitsulo komwe kumachitika chifukwa cha sipatter kumachepetsedwa, kuchuluka kwa magawo kumachulukira, ndipo zotulutsa zowotcherera zimakulanso.
