Resistance welding inzira inoshandiswa zvakanyanya yekugadzira iyo inotsamira pamisimboti yekupokana kwemagetsi kugadzira mabhondi akasimba uye akasimba pakati pezvikamu zvesimbi.Muchikamu chino, tichaongorora basa rakakosha rinoitwa nekupikiswa mukupisa zvikamu zvemuchina wekupokana welding.
Resistance welding inowanzo shandiswa mumaindasitiri akasiyana siyana, anosanganisira emotokari, aerospace, uye zvemagetsi, nekuda kwekugona kwayo kugadzira emhando yepamusoro welds.Maitiro acho anosanganisira kuisa kumanikidza kuzvidimbu zviviri zvesimbi paunenge uchipfuura nemagetsi mazviri.Kupikiswa kwemagetsi painterface pakati pezvimedu zviviri izvi kunogadzira kupisa, zvichiita kuti zvinyunguduke uye zvisanganise pamwechete.
Izvo zvekutanga zvinhu zvinopesvedzera maitiro ekudziya mumashini ekushivirira welding mashini emagetsi kuramba uye kuyerera kwazvino.Ngationgororei kuti kuramba kunobata sei maitiro ekudziya:
- Material Properties:Kupokana kwemagetsi kwechinhu kunokonzerwa nehunhu hwayo hwekuzvarwa, senge resistivity uye conductivity.Zvishandiso zvine high resistivity zvinoda simba rakawanda remagetsi kuti ridziye, nepo zvinhu zvinoitisa zvakanyanya kupisa nekukurumidza.Resistance welding machines dzakagadzirirwa kugarisa zvinhu zvakasiyana siyana nekugadzirisa iyo inoshandiswa ikozvino uye kumanikidza zvinoenderana.
- Electrode Design:Dhizaini yemawelding electrode inokanganisawo maitiro ekudziya.Electrodes inofanira kugadzirwa kubva kuzvinhu zvinokwanisa kushingirira tembiricha yakakwira uye zvine yakanaka conductivity yemagetsi.Ukuru uye chimiro che electrode zvinokanganisa kugoverwa kwekupisa uye kudzvinyirira, izvo zvinogona kukanganisa kunaka kweweld.
- Contact Resistance:Iko kusangana kwekupokana pane iyo interface pakati pee electrode uye workpieces inoita basa rakakosha mukupisa maitiro.Yakakodzera electrode alignment uye kugadzirisa kwakakosha kuti ive nechokwadi chekushomeka kwekubata kuramba.High kuonana kuramba kunogona kutungamirira kusashanda kupisa uye kushaya simba welds.
- Ikozvino Kudzora:Kunyatso kudzora kweiyo welding ikozvino kwakakosha kuti uwane inowirirana uye yemhando yepamusoro welds.Iyo yazvino nhanho inofanirwa kuenderana kune chaiyo zvinhu zviri kubatanidzwa uye inodiwa weld zvivakwa.Kusakwana ikozvino kunogona kukonzera fusion isina kukwana, nepo yakawandisa ikozvino inogona kutungamira mukupisa uye kukanganisa kunogona kuitika kune workpieces.
- Kugovera Kupisa:Mukupikisa welding, zvakakosha kudzora kugoverwa kwekupisa.Kupisa kusina kuenzana kunogona kukonzera kukanganisa kweweld senge warping, kutsemuka, kana kupinda kusina kukwana.Yakakodzera electrode alignment uye kudzvanywa kugovera kunobatsira kuve nechokwadi chekudziya yunifomu uye chisungo chakasimba.
Mukupedzisa, kunzwisisa kupesvedzera kwekupokana kwemagetsi pane yekudziya maitiro mumashini ekushingisa welding kwakakosha kuti uwane akavimbika uye emhando yepamusoro welds.Vagadziri vanofanirwa kunyatso funga nezvezvinhu zvivakwa, dhizaini ye electrode, kuramba kubata, kutonga kwazvino, uye kugovera kupisa kukwenenzvera nzira yewelding kune yavo chaiyo maapplication.Nekuita izvi, ivo vanogona kuve nechokwadi chekugadzirwa kwezvakaremara uye zvisina hurema-isina welded zvikamu, zvichibatsira kune huwandu hwese uye kuvimbika kwezvigadzirwa zvavo.
