Iyo EM12K, inoenderana neAWS A5.17 specification, inomiririra giredhi rakati rewaya yekuwedera yearc iri pasi pemvuraYakagadzirirwa kubatanidza zvakasimba zvikamu zvesimbi yekabhoni. Sechinhu chakakosha chinoshandiswa mukusanganisa arc nesimbi, mashandiro ayo akabatana nekushandiswa kweflux inoenderana panguva imwe chete. Iyi waya yekusanganisa arc nesimbi yakagadzirwa kuti igadzire ma weld deposits akasimba, anokwanisa kutsungirira kushushikana kukuru kwekushanda munzvimbo dzinoda maindasitiri.
Chinhu chinoratidza waya yekuwelda ye EM12K iri pasi pemvura ndeyekuumbwa kwayo kwemakemikoro. Waya iyi ine kabhoni yakawanda kupfuura mamwe marudzi ari muchikamu chayo. Yakabatanidzwa nehuwandu hwakakwira hwe manganese ne silicon, yakagadzirirwa zvakanyanya kupfuura huwandu hunowanikwa mu EL12 wire grade. Kuenzanisa uku kwakakosha pakuzadzisa hunhu hwemakanika hunodiwa uye maitiro esimbi mu weld yakapedzwa.
Kuwedzera kwehuwandu hwemanganese nesilicon muwaya iyi yekuwelda kunowedzera zvakanyanya kugona kwayo kubvisa oxidizing panguva yekushanda kwewelding. Ichi chinhu chakakosha chehunyanzvi, sezvo ichirwisa kuumbwa kwe porosity nekubvisa oksijeni kubva mudziva rekuwelda rakanyungudutswa. Kushandiswa kweizviwaya yekuwedera yearc iri pasi pemvuraInokurudzira kunaka kwesimbi yesimbi uye kuvimbika kwayo, zvichiita kuti ive sarudzo yakavimbika kune mashandisirwo ayo kubatanidza kwakakwana uye madhipoziti asina kukanganisa zvinosungirwa.
Simbi inosungirirwa inobva pawaya yeEM12K inoratidza kusimba kwayo uye ductility, yakakodzera kushandiswa pakugadzira zvivakwa zvinorema, midziyo yekumanikidza, ngarava, uye zvikamu zvechivakwa zvinorema zvakanyanya. Kushanda kwayo nguva dzose kunoita kuti majoini akasungirirwa arambe akasimba kwenguva refu, kunyangwe mumamiriro ezvinhu akaoma ekushanda anosanganisira kudedera kana kushushikana.
Iyo EM12Kwaya yekuwedera yearc iri pasi pemvuraimhando yepamusoro yekushandiswa kwesimbi yakakosha yekabhoni. Makemikoro ayo akasiyana, ane kabhoni yakawanda, manganese, uye silicon, anopa deoxidation yakawedzerwa uye hunhu hwakavimbika hwemakanika mumamiriro akasungirirwa. Kutevedzera mwero weAWS A5.17 kunosimbisa kunaka kwayo kwakafanana, zvichiita kuti waya iyi ive mhinduro yakanaka kumaindasitiri anoda kubatana kwakasimba uye kushanda zvakanaka.
