Resistance spot welding inzira inoshandiswa zvakanyanya muindasitiri yekugadzira, inoshandirwa kujoinha simbi mashizha nekugadzira magetsi enzvimbo panzvimbo yeweld point. Sarudzo yemagetsi emagetsi inoita basa rakakosha mukuita welding, inopesvedzera zvinhu zvakaita seweld mhando, kusimba, uye mutengo-kushanda.
1. Copper Electrodes
Mhangura electrode ndeimwe yeanonyanya kusarudzwa sarudzo dzekudzivirira nzvimbo welding michina. Ivo vanozivikanwa nekunaka kwavo kwekupisa uye kwemagetsi conductivity, iyo inobatsira mukugadzira kupisa kunodiwa kwewelding. Copper electrodes inopawo kusimba kwakanaka uye inogona kumira kutonhora kwakanyanya. Nekudaro, ivo vanowanzosakara nekufamba kwenguva uye vangangoda kudzoreredzwa kana kugadziriswa.
2. Tungsten Electrodes
Tungsten electrodes ndiyo imwe sarudzo yekudzivirira nzvimbo welding. Ivo vane nzvimbo yakakwira yekunyungudika uye yakanakisa magetsi conductivity, ichiita kuti ive yakakodzera kune welding application inosanganisira kupisa kwakanyanya uye kusagadzikana kwemagetsi. Tungsten electrodes inozivikanwa nehupenyu hwayo hurefu, asi inogona kudhura kumberi kana ichienzaniswa nemhangura electrode.
3. Refractory Metal Alloys
Mamwe ekupikisa nzvimbo welding maapplication anoda zvakatonyanya kunyungudika nzvimbo uye kusimba kupfuura izvo tungsten inogona kupa. Muzviitiko zvakadaro, refractory simbi alloys se molybdenum uye tantalum anoshandiswa. Zvishandiso izvi zvinopa kupikisa kwakasarudzika pakupisa uye ngura, zvichiita kuti ive yakanakira mabasa ehunyanzvi ekupisa. Nekudaro, mutengo wavo wakakwira unogona kuve chinhu chinodzikamisa kune yakakura maapplication.
4. Composite Electrodes
Composite electrodes inosanganisa zvinhu zvakasiyana kuti zviwane kuenzana kwezvivakwa. Semuenzaniso, copper-tungsten composite electrode inobatanidza yakanakisa conductivity yemhangura nepamusoro-tembiricha kuramba kwe tungsten. Aya ma electrode anopa kuwirirana pakati pemutengo nekuita, zvichiita kuti ive sarudzo yakakurumbira kune akawanda welding application.
5. Electrode Coatings
Mune zvimwe zviitiko, maelectrodes akaputirwa nezvinhu zvakaita sechromium kana zirconium kuti avandudze kuramba kwavo kupfeka uye kuora. Aya machira anogona kuwedzera hupenyu hwe electrode uye kuwedzera kunaka kweweld.
Mukupedzisa, kusarudzwa kwe electrode zvinhu zvekudzivirira nzvimbo welding machina zvinoenderana nezvinhu zvakasiyana, zvinosanganisira chaiyo welding application, mari inotariswa, uye inodiwa maitiro ekuita. Mhangura, tungsten, refractory metal alloys, composite materials, uye electrode coatings zvese zvine zvazvakanakira uye zvinogumira. Mainjiniya nemawelder vanofanirwa kunyatso ongorora zvinhu izvi kuti vasarudze akanyatsokodzera electrode zvinhu kune zvavanoda, pakupedzisira vachiona budiriro yewelding process.
