Pakushandisa maerekitironi pakushongedza arc, muchina wekushongedza unodiwa uri nyore, uye unogona kusarudza muchina wekushongedza weAC kana DC. Pamusoro pezvo, hapana chikonzero chekushandisa michina yekuwedzera pakubatanidza, chero bedzi paine zvishandiso zvekuwedzera zviri nyore. Michina iyi yekushongedza iri nyore pakuvaka, yakachipa pamutengo, uye iri nyore kugadzirisa. Nekuda kwekudyara mari shoma mukutenga michina, electrode arc welding yakashandiswa zvakanyanya mukugadzira maindasitiri.
Tekinoroji yekuwelda yemagetsi haina basa rekuzadza simbi muweldment chete, asiwo haidi kuwedzera gasi rekudzivirira panguva yekushandiswa. Munguva yekupisa kwemagetsi, simba riri pakati peelectrode neweldment rinogadzira dziva rakanyungudutswa, nepo electrode pachayo ichigadzira zvigadzirwa zvekupisa zvinobatana kuti zvigadzire gasi rekudzivirira rinodzivirira dziva rakanyungudutswa uye weld. Pamusoro pezvo, chimiro chetsvimbo yekuwelda chakagadzirwa kuti chisavhuvhute mhepo uye chive chakasimba mukudzivirira mhepo, zvichigonesa welding yemhando yepamusoro munzvimbo ine mhepo.
Electrode arckusonaine mabhenefiti ekushanda kuri nyore uye kushandiswa kwakasiyana-siyana. Yakakodzera kusanganisa zvigadzirwa zvishoma kana mabhechi madiki, kunyanya ma weld akaoma kusanganisa nemichina yakaita semaumbirwo asina kujairika uye kureba kupfupi. Paunenge uchishandisa tekinoroji ye stick arc welding, nzvimbo ye welding haina muganho, uye inogona kushandiswa zviri nyore kunyangwe munzvimbo dzakamanikana kana munzvimbo dzakaoma. Pamusoro pezvo, michina inodiwa tekinoroji ye electrode arc welding iri nyore, hapana gasi rekubatsira rinoshandiswa, uye hunyanzvi hwemushandisi hahuna kukwira zvakanyanya.
Kushandiswa kwetekinoroji ye electrode arc welding kwakakura kwazvo, uye yakakodzera kusanganisa simbi dzinenge dzose dzakajairwa uye alloys. Nekusarudza electrode chaiyo, kusanganisa kunogona kuwanikwa pazvinhu zvakasiyana, zvinosanganisira simbi isina alloy yakawanda, simbi yekabhoni, simbi ine alloy yakawanda uye simbi dzakasiyana-siyana dzisina ferrous. Pamusoro pezvo, ma electrode anogona kushandiswa kusanganisa mhando dzakasiyana dzebasa, dzakadai sesimbi dzakasiyana, pamwe nemabasa akasiyana-siyana ekusanganisa akadai sekugadzirisa kusanganisa simbi yakakandwa uye kusanganisa pamusoro pesimbi dzakasiyana-siyana. Electrode pachayo inogonawo kupa huwandu hwakati hwegasi rekudzivirira kudzivirira matambudziko akadai sekuoxidation kwe weld. Panguva imwecheteyo, simbi inozadza inogona zvakare kuwedzera simba uye kugara kwenguva refu kwe weld. Munzvimbo dzakaoma dzakadai semhepo ine simba, tekinoroji yekubatanidza electrode arc welding inogonawo kuchengetedza mhedzisiro yakanaka, ichivimbisa mhando uye kushanda zvakanaka kwemabasa ekusanganisa.
Maitiro ekubatanidza anotsanangurwa zvichienderana nehunhu hwesimbi, uye zvinhu zvakasiyana zvesimbi zvinoda matekiniki ekubatanidza anoenderana. Kazhinji, simbi yekabhoni, simbi isina alloy yakawanda, simbi isingatsvi, simbi isingatsvi, mhangura uye alloys dzayo zvinogona kusungirirwa nenzira dzemazuva ano dzekubatanidza. Zvisinei, kune zvimwe zvinhu zvesimbi, zvakaita sesimbi yakakandwa, simbi ine simba guru uye simbi yakaoma, kupisa kana kurapwa mushure mekupisa kunogona kudiwa, kana matekiniki ekubatanidza akabatanidzwa anogona kushandiswa. Zvisinei, simbi dzine nzvimbo yakaderera yekunyunguduka (senge zinc, lead, tin uye alloys dzadzo) uye simbi dzisingagadzirisike (senge titanium, niobium, zirconium, nezvimwewo) hadzigone kusungirirwa uchishandisa maitiro ekubatanidza akajairika. Saka, usati wabatanidza, zvakakosha kuongorora nekuongorora zvinhu zvakanyatsonaka, uye kusarudza tekinoroji yakakodzera yekubatanidza uye maitiro zvichienderana nemamiriro chaiwo.
Zvigadzirwa zvakadaro zvinowanzova nemaumbirwo akaomarara uye maumbirwo akasiyana-siyana, zvichida mashandiro emaoko uye maitiro ekubatanidza akapfava kuti ive nechokwadi chekuti welding yakanaka uye yakavimbika. Sezvo maitiro ekubatanidza achida hunyanzvi hwehunyanzvi uye ruzivo, nzira dzekugadzira dzakagadzirwa nemashini uye otomatiki hadzina kukodzera rudzi urwu rwechigadzirwa. Panguva imwe chete, rudzi urwu rwechigadzirwa runowanzova nemutengo wakakwira kana boka diki rekugadzira, uye rinoda kugadzirwa nenzira yakanangwa. Saka, kune rudzi urwu rwechigadzirwa, nzira yakakodzera yekugadzira ndeye welding nemaoko uye kugadzirwa kweboka diki kuti ive nechokwadi chekuti chigadzirwa chacho chakanaka uye chinoshanda. Panguva imwe chete, tekinoroji yehunyanzvi neruzivo zvinodiwawo pakuiswa nekugadzirisa kuti ive nechokwadi chekushandiswa kwakajairika uye kuchengetedzeka kwechigadzirwa.
