Siyini isizathu se-electrode enamathelayo ngesikhathi sokushisela

Ukunamathela kwe-Electrode yinto ye-electrode futhi ingxenye inamathelana lapho indawo yokushisela ishisela kanye ne-electrode nezingxenye zakhe ukushisela okungavamile. Ezimweni ezimbi kakhulu, i-electrode ikhishwa futhi ukugeleza kwamanzi okupholisa kubangela ukuthi izingxenye zigqwale.
Kunezizathu ezine eziyinhloko zokunamathela kwe-electrode ngesikhathi sokushisela: izindawo zokusebenza zama-electrode amabili azihambisani, izindawo zokusebenza zama-electrode zilukhuni, ingcindezi ye-electrode ayanele, kanye nepayipi lamanzi endaweni yokupholisa yesibhamu sokushisela. exhunywe emuva noma ukujikeleza kwamanzi okupholisa kuvinjiwe.

Imishini yokushisela i-Xinfa inezici zekhwalithi ephezulu nenani eliphansi. Ukuze uthole imininingwane, sicela uvakashele:Abakhiqizi Bezinto Zokushisela Nabasika - Imboni Yokushisela & Cutting yase-China & Suppliers (xinfatools.com)

1. Izindawo zokusebenza zama-electrode amabili azihambelani

Lapho izindawo zokusebenza zama-electrode amabili zingahambisani, izindawo zokusebenza zama-electrode zizoxhumana kancane nezingxenye, ukumelana nokuxhumana phakathi kwama-electrode kanye nezingxenye kuzokwanda, futhi i-current of the welding circuit izokwehla.

Lapho i-current igxiliwe endaweni yokuxhumana yendawo, futhi ukuminyana kwamanje endaweni yokuxhumana kukhulu kunomthamo wamanje wendawo yokusebenza ye-electrode ngesikhathi sokushisela okujwayelekile, izinga lokushisa lephoyinti lokuxhumana likhuphukela ekushiseni okushiselwe kwe-electrode. futhi ingxenye, kanye ne-electrode kanye nengxenye kuzohlanganiswa.

2. Indawo yokusebenza ye-electrode ilukhuni

Indawo yokusebenza ye-electrode ayikwazi ukufakwa ngokuphelele nengxenye, futhi izingxenye ezithile eziphumayo kuphela ezixhumene nengxenye. Lesi simo sizophinde sibangele ukuthi izindawo zokusebenza zama-electrode amabili zingahambelani, okuholela kuma-electrode anamathelayo.

3. Ukucindezela kwe-electrode okunganele

Ukumelana nokuxhumana kuhambisana ngokuphambene nengcindezi. Ukucindezela kwe-electrode okunganele kwandisa ukumelana kokuxhumana phakathi kwe-electrode nengxenye, futhi ukushisa kokumelana kwengxenye yokuxhumana kuyanda, ukuze izinga lokushisa lendawo yokuthintana phakathi kwe-electrode nengxenye likhuphuke liye ezingeni lokushisa elishiselayo, ngaleyo ndlela kwakheka uxhumano lwe-fusion phakathi i-electrode kanye nengxenye.

4. Ipayipi lamanzi lendawo yokupholisa isibhamu sokushisela lixhunywe emuva noma ukujikeleza kwamanzi okupholisa kuvinjiwe.

Ipayipi lamanzi lendawo yokupholisa isibhamu sokushisela lixhunywe emuva noma ukujikeleza kwamanzi okupholisa kuvinjiwe, izinga lokushisa le-electrode liyakhuphuka, futhi i-electrode kanye nengxenye ingahlanganiswa ngesikhathi sokushisela indawo eqhubekayo.

Izimo ezine ezingenhla kungenzeka zibangele ukuthi i-electrode nengxenye kuhlanganiswe futhi kuxhunywe, okuholela kumkhuba onamathelayo we-electrode. Ngakho-ke, ungakugwema kanjani ukwenzeka kwezinto ezinamathelayo ze-electrode?

(1) Fayela ikhanda le-electrode ukuze wenze izindawo zokusebenza zama-electrode amabili zihambisane futhi zingabi namahholo. Inqubo yokushisela ingakhethwa njengenqubo yokugaya (akukho okukhiphayo kwamanje), futhi izindawo zokusebenza zama-electrode amabili zingabhekwa njengokufana ngokudubula isibhamu sokushisela.

(2) Esimeni sokugaya, shisa isibhamu sokushisela izikhathi ezi-5 kuye kweziyi-10 ukuze wenze izindawo zokusebenza zama-electrode amabili ukwandisa indawo yokuxhumana ngaphakathi kobubanzi obucacisiwe bekhanda le-electrode futhi uthuthukise ubulukhuni bobuso.

+ i-electrode kanye nengxenye.

(4) Faka umthofu obomvu olungiselelwe umshiseli endaweni yokusebenza ye-electrode ukuze ucekele phansi ukushisela phakathi kwe-electrode nengxenye.

(5) Lungisa ingcindezi ye-electrode futhi usebenzise imingcele yokushisela ngokucindezela okukhulu, ukunikezwa kwamandla amakhulu kanye nesikhathi esifushane samandla.

(6) Hlanza ipayipi lamanzi okupholisa njalo ukuze uqinisekise ukugeleza kwamanzi okupholisa. Okungenhla yizo zonke izinyathelo ezingaxazulula inkinga yokunamathela ama-electrode ngesikhathi sokushisela.
