Nzira yekusarudza sei electrode zvinhu zvepakati frequency nzvimbo welding muchina?

Nzira yekusarudza sei electrode zvinhu zvepakati frequency nzvimbo welding muchina? Spot welding electrode musoro kuburikidza neyazvino yezviuru kusvika makumi ezviuru zveamperes, inomira nevoltage ye9.81 ~ 49.1MPa, pakarepo tembiricha ye600 ℃ ~ 900 ℃. Naizvozvo, iyo electrode inodiwa kuti ive yakanaka yemagetsi conductivity, thermal conductivity, thermal hardness uye high corrosion resistance.

Spot welding electrodes inogadzirwa nemhangura alloys. Kuti uvandudze mashandiro emhangura alloy electrode, zvinowanzodikanwa kuti upinde mukusimbisa kurapwa, senge: kutonhora kugadzirisa kusimba, kusimba kwemhinduro kusimba, kuchembera kwemvura kusimbisa uye kupararira kusimba. Kuitwa kwe electrode kunoshandukawo mushure mekurapa kwakasiyana kwekusimbisa. Kana mahwendefa esimbi anotonhora-akakungurutswa, mahwendefa esimbi, simbi isina tsvina kana mahwendefa ealuminium anoda kuve akaiswa mavara-welded, zvakakodzera electrode zvinhu zvinofanirwa kusarudzwa zvinoenderana nehunhu hwemidziyo yeplate.

Kusarudzwa kwezvinhu zve electrode zvespot welding galvanized steel plate kunofanira kuderedza kusvibiswa uye deformation ye electrode panguva yekuputika kwemavara, izvo zvinoda kuoma kwepamusoro, kunaka kwemagetsi uye kupisa kwemagetsi e electrode pakupisa kwepamusoro, uye maitiro maduku alloying ane zingi.

Hupenyu hwemagetsi emagetsi esimbi yesimbi welding ine akati wandei maelectrode zvinhu hurefu kupfuura hwecadmium copper electrode. Nekuti kunyangwe iyo yemagetsi uye yekupisa conductivity yecadmium copper iri nani, zvinotendwa kuti kunamatira zinc kushoma, asi kutaura zvazviri, nekuda kwekudzikira kwayo kunyorova, kukanganisa kwekuoma kwekushisa kwakanyanya. Iyo yakanyanya tembiricha yakaoma ye zirconium mhangura yakakwirira, saka hupenyu hwayo zvakare hwakareba. Kunyangwe iyo yakanyanya tembiricha kuomarara kweberyllium diamond mhangura yakakwira, nekuti iyo conductivity yakashata zvakanyanya kupfuura yechromium-zirconium mhangura, iyo conductivity uye yekupisa conductivity inoita basa guru mukupesvedzera kwehupenyu hwayo, uye hupenyu hwayo hwe electrode hwakaderera.

Uye zvakare, kushandiswa kwe tungsten (kana molybdenum) yakamisikidzwa composite electrode welding galvanized steel plate, hupenyu hwayo hwakakwirawo, kunyangwe conductivity ye tungsten, molybdenum yakaderera, chete 1/3 yekromium mhangura, asi kunyorova kwayo kwakakwira. (1273K), kuoma kwekushisa kwepamusoro (kunyanya tungsten), iyo electrode haisi nyore deformation.
