Resistance spot welding inzira inoshandiswa zvakanyanya mumaindasitiri ekugadzira kujoinha zvinhu zvesimbi zvakanaka. Kuve nechokwadi chemhando yemapoinzi weld kwakakosha kuchengetedza kurongeka kwechimiro uye kuchengetedzeka kwechigadzirwa chekupedzisira. Munyaya ino, isu tichakurukura nzira yekuona weld point mhando mumashini ekudzivirira nzvimbo welding.
Resistance spot welding inzira inobatanidzwa zvidimbu zviviri zvesimbi nekuisa kupisa uye kumanikidza panzvimbo dzakati. Hunhu hweiyo weld point hunoenderana nezvinhu zvakasiyana, kusanganisira welding paramita, zvinhu zvemukati, uye mamiriro emagetsi emagetsi. Kuona uye kuve nechokwadi chemhando yeaya weld mapoinzi kwakakosha kudzivirira kukanganisa uye kuchengetedza kuvimbika kweiyo welded zvikamu.
Nzira yekuona Weld Point Hunhu
- Visual Inspection: Nzira iri nyore yekuona weld point mhando ndeyekutarisa kwekuona. Vashandi vane hunyanzvi vanogona kuongorora maweld poinzi kune zvisizvo senge makatsemuka, voids, kana kusakwana kupinda. Kuongorora kwekuona kunopa mhinduro nekukurumidza uye kazhinji ndiyo yekutanga mutsara wekudzivirira mukutonga kwemhando.
- Ultrasonic Testing: Ultrasonic yekuongorora inzira isingaparadzi iyo inoshandisa yakakwirira-frequency mafungu eruzha kuti aongorore weld chimiro chemukati. Inogona kuona zvikanganiso zvemukati zvingave zvisingaoneki kuburikidza nekuongorora kwekuona, zvakadai sekuputika kwakavanzika kana voids.
- X-ray Kuongorora: X-ray kuongorora ndiyo imwe nzira isingaparadzi inopa mufananidzo wakadzama wemukati we weld chimiro. Inoshanda zvakanyanya pakuona kukanganisa kwemukati uye kuve nechokwadi chekutendeseka kweakakosha weld point.
- Weld Current uye Voltage Monitoring: Kutarisa welding ikozvino uye voltage panguva yekugadzira welding inogona kupa ruzivo rwechokwadi-nguva pamusoro pehutano hweweld. Kutsauka kubva kune yakatarwa parameter kunogona kuratidza nyaya ne weld, senge kusabatana zvakanaka kana kusapindirana kwezvinhu.
- Shear uye Tensile Testing: Kuti uongorore simba remuchina we weld, sampuli dzinogona kuiswa kune shear uye tensile bvunzo. Maedzo aya anoona kugona kweweld kushingirira masimba ekunze uye kuona kuti inosangana nezvinodiwa zvesimba.
- Microstructural Analysis: Microstructural analysis inosanganisira kuongorora weld's microstructure pasi pemaikorosikopu. Iyi nzira inogona kuburitsa ruzivo nezve weld chimiro chezviyo, icho chinogona kukanganisa michina yayo.
- Dye Penetrant Testing: Dhayi inopinda muyedzo inzira inoshandiswa kuona kuremara kwepamusoro mumawelds. Dhayi inopinza inoshandiswa kune weld surface, uye chero dhayi yakawandisa inodzimwa. Dhayi inopinda mukati mehurema hwepamusoro, ichiita kuti ionekwe pasi pechiedza cheUV.
- Magnetic Particle Testing: Iyi nzira yakanakira kuona pamusoro uye padyo-yepamusoro-yakakanganiswa mune ferromagnetic zvinhu. Magnetic particles anoiswa kune weld, uye chero kukanganisa musimba remagineti kunokonzerwa nekuremara kunoonekwa.
Kuve nechokwadi chemhando yeweld point mumashini ekushivirira welding kwakakosha kuchengetedza kutendeseka kwezvinhu zvakashongedzwa. Kushandisa musanganiswa wekutarisa kwekuona uye kusaparadza nzira dzekuyedza dzakadai seye ultrasonic bvunzo, X-ray yekuongorora, uye weld ikozvino yekutarisa inogona kubatsira kuona hurema uye kutsauka kubva pamhando yemhando. Mechanical kuyedzwa uye microstructural ongororo inowedzera kuve nechokwadi chekuti welds inosangana nesimba rinodiwa uye zvimiro zvakatemwa. Nekushandisa nzira idzi, vagadziri vanogona kugadzira zvigadzirwa zvemhando yepamusoro-welded nechivimbo.
