Resistance spot welding inzira inoshandiswa zvakanyanya mumaindasitiri akasiyana ekubatanidza simbi. Kubudirira uye kunaka kwemaitiro aya kunonyanya kuenderana nemidziyo inoshandiswa kune welding electrodes. Muchinyorwa chino, isu tichaongorora zvakakosha zvinhu zvekufunga nezvazvo pakusarudza electrode zvinhu zvekupikisa nzvimbo welding michina.
- Conductivity: Iyo magetsi emagetsi emagetsi emagetsi akakosha pakugadzira kupisa kwakanaka panguva yewelding. Mhangura uye alloys ayo, akadai semhangura-chromium uye mhangura-zirconium, isarudzo dzakakurumbira nekuda kwekukwirira kwemagetsi. Ivo vanobvumira zviri nani kufambisa simba uye kubatsira mukuwana anowirirana welds.
- Kudzivirira Kupisa: Resistance spot welding inogadzira huwandu hwakakura hwekupisa, kunyanya panzvimbo dzekusangana dzemagetsi. Naizvozvo, iyo yakasarudzwa electrode zvinhu zvinofanirwa kuve neyakanakisa kupisa kwekudzivirira kuti irambe ichishanda kwenguva refu pasina deformation kana kushatisa. Refractory simbi senge tungsten uye molybdenum inozivikanwa nekusarudzika kwayo kupisa.
- Kuoma: Kuti ive nechokwadi chekugadzikana uye kunoenderana weld, iyo electrode zvinhu zvinofanirwa kuve nekuoma kwakakwana kuramba kupfeka uye deformation panguva yewelding. Zvinhu zvakaomarara zvinogona kuchengetedza chimiro chazvo uye kupa yakavimbika welding nzvimbo kwenguva yakareba. Zvinhu zvakadai semhangura-chromium-zirconium (CuCrZr) inozivikanwa nokuda kwekuoma kwavo kwepamusoro uye kusimba.
- Thermal Conductivity: Kunze kwemagetsi conductivity, thermal conductivity chinhu chakakoshawo. Kunyatsopisa kupisa kubva munzvimbo ye weld kunokosha kudzivirira kupisa uye kuchengetedza weld quality. Copper-based electrodes, nekuda kwekukwirira kwavo kwekushisa kwekushisa, inowanzosarudzwa nekuda kwechikonzero ichi.
- Welding process uye Material Compatibility: Funga nezve chaiyo welding maitiro uye zvinhu zviri kubatanidzwa. Zvishandiso zvakasiyana zvingada zvinhu zvakasiyana-siyana zve electrode. Semuyenzaniso, kana welding high-simba simbi, maelectrodes ane zvakanaka kuramba kupfeka uye deformation pasi kumanikidzwa mukuru anogona kudiwa.
- Kufunga Kwemitengo: Mutengo wezvinhu zve electrode unogona kusiyana zvakanyanya. Nepo zvinhu zvakaita semhangura yakachena zvinopa yakanakisa conductivity, zvinogona kunge zvisingadhure kune ese maapplication. Kuenzanisa mashandiro ekuita nezvinonetsa bhajeti kwakakosha.
- Maintenance: Kugara kugadziridzwa kwe electrode kwakakosha pakugara kwenguva refu kwemidziyo yewelding. Zvimwe zvinhu zve electrode zvingada kuchengetedzwa kakawanda kupfuura zvimwe. Funga kusununguka kwekugadzirisa paunosarudza zvinhu zve electrode.
Mukupedzisa, kusarudzwa kwezvinhu zve electrode kunoita basa rakakosha mukuita uye kugona kwemashini ekudzivirira nzvimbo welding. Mainjiniya nevagadziri vanofanirwa kunyatso ongorora izvo chaizvo zvinodikanwa zvekushandisa kwavo welding uye kusarudza zvinhu zvinopa chiyero chakakodzera che conductivity, kupisa kupisa, kuoma, uye mutengo-kushanda. Maitiro ekugadzirisa anofanirwa kuitwa zvakare kuti ave nechokwadi chekuti ma electrode 'akareba uye anowirirana weld mhando.
