Chifukwa chiyani electrode yomata pa nthawi yowotcherera

Electrode kumamatira ndi chodabwitsa cha elekitirodi ndi mbali kumamatira pamodzi pamene welder malo welds ndi elekitirodi ndi mbali kupanga weld wachilendo. Pazovuta kwambiri, electrode imatulutsidwa ndipo kutuluka kwa madzi ozizira kumapangitsa kuti ziwalozo zichite dzimbiri.
Pali zifukwa zinayi zazikulu zomwe ma elekitirodi amamatira panthawi yowotcherera: malo ogwirira ntchito a maelekitirodi awiriwo safanana, malo ogwirira ntchito a ma elekitirodi ndi ovuta, kuthamanga kwa electrode sikukwanira, ndi chitoliro chamadzi pamalo ozizira a mfuti yowotcherera. olumikizidwa mobwerera kapena kufalikira kwa madzi ozizira kwatsekedwa.

Zida zowotcherera za Xinfa zili ndi mawonekedwe apamwamba komanso otsika mtengo. Kuti mudziwe zambiri, chonde pitani:Opanga Kuwotcherera & Kudula - China Welding & Cutting Factory & Suppliers (xinfatools.com)

1. Malo ogwirira ntchito a maelekitirodi awiri sali ofanana

Pamene malo ogwirira ntchito a maelekitirodi awiri sali ofanana, malo ogwirira ntchito a ma electrode adzakhala okhudzana ndi magawo, kukana kukhudzana pakati pa ma elekitirodi ndi zigawozo kudzawonjezeka, ndipo mphamvu yozungulira yowotcherera idzachepa.

Pamene panopa anaikira pa malo kukhudzana m'deralo, ndipo kachulukidwe panopa pa malo kukhudzana ndi wamkulu kuposa kachulukidwe panopa ntchito pamwamba pa elekitirodi pa kuwotcherera yachibadwa, kutentha kwa malo kukhudzana limakwera kwa weldable kutentha kwa elekitirodi. ndipo gawo, ndi elekitirodi ndi gawo zidzasakanizidwa.

2. Malo ogwirira ntchito a electrode ndi ovuta

Malo ogwirira ntchito a electrode sangathe kuikidwa kwathunthu ndi gawolo, ndipo mbali zina zotulukapo zimalumikizana ndi gawolo. Izi zipangitsanso kuti malo ogwirira ntchito a maelekitirodi awiriwa asafanane, zomwe zimapangitsa kuti ma elekitirodi omata.

3. Kuthamanga kwa electrode kosakwanira

Kukana kulumikizana kumayenderana mosagwirizana ndi kukakamizidwa. Kuthamanga kosakwanira kwa elekitirodi kumawonjezera kukana kukhudzana pakati pa elekitirodi ndi gawolo, ndipo kukana kutentha kwa gawo lolumikizana kumawonjezeka, kotero kuti kutentha kwa malo olumikizana pakati pa ma elekitirodi ndi gawolo kumakwera mpaka kutentha komwe kungathe kutenthedwa, potero kupanga kulumikizana pakati electrode ndi gawo.

4. Chitoliro chamadzi cha malo ozizirirapo mfuti zowotcherera chimalumikizidwa kumbuyo kapena kufalikira kwa madzi ozizira kwatsekedwa.

Chitoliro chamadzi cha malo ozizirirapo mfuti chowotcherera chimalumikizidwa mobwerera kumbuyo kapena kuzungulira kwa madzi ozizira kwatsekedwa, kutentha kwa ma elekitirodi kumakwera, ma elekitirodi ndi gawolo limatha kusakanikirana panthawi yowotcherera mosalekeza.

Zinthu zinayi zomwe zili pamwambazi zitha kupangitsa kuti ma elekitirodi ndi gawolo asakanike ndikulumikizidwa, zomwe zimapangitsa kuti pakhale chodabwitsa cha electrode. Ndiye mungapewe bwanji kuchitika kwa chodabwitsa cha electrode chomata?

(1) Lembani mutu wa electrode kuti malo ogwira ntchito a maelekitirodi awiri akhale ofanana komanso opanda roughness. Njira yowotcherera imatha kusankhidwa ngati njira yopera (palibe chotulukapo), ndipo malo ogwirira ntchito a maelekitirodi awiri amatha kuwoneka kuti akufanana ndi kuwombera mfuti yowotcherera.

(2) M'malo akupera, womberani mfuti yowotcherera ka 5 mpaka 10 kuti mupange malo ogwirira ntchito a maelekitirodi awiri kuti muwonjezere malo olumikizirana mkati mwamtundu wina wamtundu wa electrode m'mimba mwake ndikuwongolera kuuma kwapamwamba.

(3) Kutenthetsa ntchito pamwamba pa elekitirodi ndi lawi la oxyacetylene kupanga okusayidi wosanjikiza (okusayidi wosanjikiza) pa ntchito pamwamba pa elekitirodi, amene angathe kuonjezera kusungunuka kwa ntchito pamwamba pa elekitirodi ndi kuwononga weldability pakati pa electrode ndi gawo.

(4) Ikani chitsogozo chofiira chokonzedwa ndi wowotcherera kumalo ogwirira ntchito a elekitirodi kuti awononge kutsekemera pakati pa electrode ndi gawolo.

(5) Sinthani mphamvu ya elekitirodi ndi ntchito magawo kuwotcherera ndi kuthamanga kwambiri, mphamvu yaikulu ndi yochepa mphamvu pa nthawi.

(6) Tsukani chitoliro cha madzi ozizira nthawi zonse kuti madzi ozizira ayende. Pamwambapa ndi miyeso yonse yomwe ingathetse vuto la kumamatira maelekitirodi panthawi yowotcherera.
