Resistance spot welding inzira inoshandiswa zvakanyanya mukugadzira, kunyanya mumaindasitiri emotokari uye aerospace, uko kudiwa kwemawelds akasimba uye akavimbika kwakakosha. Iyi nzira inosanganisira kushandiswa kwemagetsi emagetsi uye kumanikidzwa kubatanidza zvidimbu zviviri zvesimbi pamwechete. Imwe yakakosha parameter mukupikisa nzvimbo welding inguva yewelding, iyo inoita basa rakakosha pakuona kunaka uye kusimba kweiyo weld. Muchikamu chino, tichaongorora hukama hwakaoma pakati penguva yewelding uye electrode displacement, tichijekesa zvinhu zvinopesvedzera simba iri.
Resistance spot welding, inowanzonzi spot welding, inzira yekubatanidza inotsamira pakuiswa kwenzvimbo yekupisa kunogadzirwa nemagetsi kuramba panguva yekusangana pakati pezvidimbu zviviri zvesimbi. Electrodes anoshandiswa kuisa kumanikidza uye ikozvino kugadzira weld nugget. Nguva yekuyerera ikozvino, inozivikanwa sewelding nguva, chinhu chakakosha mukubudirira kweiyo welding process.
Welding Nguva uye Impact Yayo
Nguva yewelding inobata zvakananga ukuru uye kunaka kwe weld nugget. Nguva refu yewelding inokonzeresa mawelds akakura uye akawedzerwa, nepo nguva pfupi dzichigadzira madiki, asina kudzika. Hukama pakati penguva yewelding uye electrode displacement yakaoma uye zvinoenderana nezvinhu zvakasiyana, zvinosanganisira zvinhu zvenyama, electrode geometry, uye welding ikozvino.
Zvinhu Zvinokonzera Electrode Displacement
a. Hukuru hwezvinhu:Zvishongo zvakakora zvinowanzoda nguva yakareba yewelding kuti ive nechokwadi chekupinda uye kusanganisa. Sezvo nguva yewelding ichiwedzera, iyo electrode displacement inowedzerawo kugadzirisa kuwedzera kupisa uye kumanikidza kunodiwa.
b. Electrode Force:Simba rinoshandiswa ne electrode rinokanganisa electrode displacement. Masimba emagetsi epamusoro anogona kutungamira kukurumidza kufamba kwe electrode nekuda kwekuwedzera kudzvanywa, zvichikonzera kupfupika kwewelding nguva.
c. Electrode Design:Chimiro uye saizi yemagetsi anoita basa rakakosha. Akasiyana magadzirirwo emagetsi anogona kuve neakasiyana mhedzisiro pakufambiswa kwe electrode, kunyangwe yenguva imwe chete yewelding.
d. Welding Current:The welding current intensity inokanganisa kukurumidza kunoita weld nugget. Makwikwi epamusoro anowanzo konzera kukurumidza kusimuka kweelectrode uye nguva pfupi yewelding.
Kunzwisisa hukama pakati penguva yewelding uye electrode displacement kwakakosha kuti uwane anowirirana uye emhando yepamusoro welds. Vagadziri vanogona kudzora hukama uhu nekugadzirisa welding paramita uye nekungwarira kusarudza electrode zvinhu uye magadzirirwo.
Munzvimbo yeresitorendi nzvimbo welding, hukama pakati penguva yewelding uye electrode displacement iine simba uye ine mativi mazhinji. Sezvatakaongorora, zvinhu zvakaita sehukobvu hwezvinhu, simba re electrode, dhizaini ye electrode, uye welding zvazvino zvese zvinopinda. Kuziva hukama uhwu kwakakosha pakugadzira akavimbika uye akasimba welds mune akasiyana maindasitiri maapplication. Vatsvagiri uye mainjiniya vanoramba vachiferefeta nekunatsa kubatana uku kusunda miganhu yezvinogoneka munyika yenzvimbo welding.
