Resistance spot welding inzira inoshandiswa zvakanyanya yekubatanidza simbi dzakasiyana siyana, kusanganisira masimbi emhangura.Iyi nzira inotsamira pakushandiswa kwekupisa kunogadzirwa nemagetsi kuramba kugadzira mawelds akasimba, akasimba.Muchikamu chino, tichaongorora maitiro ekupikisa nzvimbo welding copper alloys uye kukurukura matanho akakosha anobatanidzwa.
Kunzwisisa I
1. Kugadzirira kwezvinhu:
Usati watanga kugadzira welding, zvakakosha kuve nechokwadi kuti zvimedu zvemhangura zvinosanganiswa zvakachena uye hazvina kusvibiswa.Chero kusvibiswa kwepamusoro kunogona kukanganisa kunaka kweweld.Kuchenesa kunowanzoitwa uchishandisa waya brashi kana kemikari solvent.
2. Kusarudzwa kweElectrodes:
Sarudzo ye electrode yakakosha mukushingisa nzvimbo welding.Electrodes inofanira kugadzirwa nechinhu chinogona kumira kutonhora kwakanyanya kunogadzirwa panguva yekugadzira welding.Copper electrodes anowanzo shandiswa kugadzira alloys yemhangura nekuda kwekuita kwavo kwakanakisa uye kusimba.
3. Kuisa Welding Parameters:
Kunyatso kumisa maparamita ewelding kwakakosha kuti uwane inobudirira weld.Iyo parameter yekutarisisa inosanganisira:
- Welding current: Huwandu hwemagetsi anoshandiswa panguva yewelding process.
- Welding nguva: Nguva iyo ikozvino inoshandiswa.
- Electrode force: Kumanikidza kunoshandiswa kune ma workpiece nema electrode.
Izvo zvakakosha zvezviyero izvi zvinoenderana nehupamhi uye kuumbwa kwemhangura alloy iri kugadzirwa.
4. Welding Process:
Kana iyo welding parameter yaiswa, iyo chaiyo welding process inogona kutanga.Iwo maworkpiece akaiswa pakati pema electrode, kuve nechokwadi chekusangana kwemagetsi.Kana iyo welding ikozvino yaiswa, kuramba panzvimbo dzekusangana kunoburitsa kupisa, zvichiita kuti alloy yemhangura inyunguduke uye isanganise pamwechete.Simba re electrode rinovimbisa kusangana kwakakodzera uye rinobatsira kuumba weld.
5. Kutonhodza uye Kuongorora:
Mushure mekuputika, zvakakosha kubvumira weld kuti itonhorere zvakasununguka kana nekushandisa nzira inodzorwa yekutonhodza kudzivirira kuumbwa kwehurema.Kana yatonhodzwa, weld inofanira kuongororwa kunaka.Izvi zvinosanganisira kutarisa kutsemuka, porosity, uye fusion chaiyo.Kana paine chakakanganisika chikaonekwa, weld ingangoda kugadziriswa kana kuvandudzwa.
6. Post-Weld Treatment:
Mune zvimwe zviitiko, kurapwa kwemashure-weld kungave kuri madikanwa kuti uvandudze ma mechanic properties ye weld kana kuderedza kusara kwekunetsa.Izvi zvinogona kusanganisira maitiro akadai seannealing kana kuderedza kushushikana.
Mukupedzisa, resistance spot welding inzira inoshanda kwazvo yekubatanidza ma alloys emhangura kana yaitwa nemazvo.Nekutevera matanho akataurwa pamusoro apa uye kunyatso kudzora maparamendi ekushongedza, zvinokwanisika kugadzira yakasimba uye inovimbika welds mumhangura alloys, zvichiita kuti iyi nzira ive chishandiso chakakosha mumaindasitiri akasiyana siyana anoshandiswa alloys emhangura.
