Kusina-kuparadza kuyedzwa (NDT) inoita basa rakakosha mukuona kunaka uye kutendeseka kwemawelds anogadzirwa nepakati frequency inverter spot welding michina. Nekushandisa nzira dzakasiyana siyana dzeNDT, vagadziri vanogona kuona hurema uye kukanganisa mune welds pasina kukonzeresa kukuvadzwa kwezvinhu zvakasungwa. Ichi chinyorwa chinoongorora akati wandei asingaparadze nzira dzekuyedza dzinoshandiswa mune yepakati frequency inverter spot welding michina uye inokurukura kukosha kwavo mukusimbisa kwemhando.
- Kuongorora Kwekuona: Kuongorora kwekuona inzira yakakosha asi yakakosha yeNDT inosanganisira kuongorora nekuona weld nenzvimbo dzakatenderedza kune kusarongeka kwepasi, discontinuities, kana kumwe kukanganiswa kunoonekwa. Vaongorori vane hunyanzvi vanoshandisa magetsi akakwana uye maturusi ekukurisa kunyatsoongorora weld uye kuona chero zviratidzo zvemhando yemhando, sekutsemuka, porosity, kana kusakwana fusion.
- Radiographic Testing (RT): Kuongororwa kweRadiographic kunoshandisa X-rays kana gamma rays kuongorora chimiro chemukati chewelds. Nenzira iyi, firimu reradiographic kana digital detector inotora mwaranzi inotapurirwa, ichigadzira mufananidzo unoratidza hurema hwemukati, senge voids, inclusions, kana kushaya kwekupinda. Kuongororwa kweRadiographic kunopa ruzivo rwakakosha mumhando uye kutendeseka kweiyo welds, kunyanya mune dzakakora kana dzakaoma weldments.
- Ultrasonic Testing (UT): Ultrasonic bvunzo inoshandisa yakakwirira-frequency mafungu eruzha kuti aone kukanganisa kwemukati uye kuyera ukobvu hwewelds. Nekutumira mafungu e ultrasonic munzvimbo ye weld uye nekuongorora masaini anoratidzwa, UT michina inogona kuona hurema hwakadai sekutsemuka, voids, kana fusion isina kukwana. UT inonyanya kubatsira pakuona kukanganiswa kwepasi uye kuve nechokwadi chekunzwika kwewelds mumashandisirwo akakosha.
- Magnetic Particle Testing (MT): Magnetic particle testing inzira inonyanya kushandiswa kuona pamusoro uye pedyo-pamusoro pehurema mune ferromagnetic zvinhu. Muchiitiko ichi, magnetic field inoshandiswa kune weld area, uye iron particles (zvichida yakaoma kana yakamiswa mumvura) inoshandiswa. Izvo zvimedu zvinoungana munzvimbo dzemagineti flux kuvuza kunokonzerwa nekuremara, zvichiita kuti zvionekwe pasi pemamiriro emwenje chaiwo. MT inoshanda pakuona kutsemuka kwepasi uye zvimwe zvisizvo muma welds.
- Penetrant Testing (PT): Penetrant testing, inozivikanwawo sedhayi inopinza yekuongorora, inoshandiswa kuona kuremara kwepamusoro-soro mumawelds. Maitiro acho anosanganisira kuisa dhayi yemvura kune weld pamusoro, ichibvumira kuti ipinde mune chero hurema hwepamusoro necapillary action. Mushure menguva yakatarwa, dhayi yakawandisa inobviswa, uye mugadziri anoshandiswa kuburitsa dhayi rakabatwa. Iyi nzira inoratidza zviratidzo zvekutsemuka, porosity, kana kumwe kukanganisa kwepamusoro.
Nzira dzisiri dzekuparadza dzekuyedza dzinoita basa rakakosha mukuongorora mhando uye kutendeseka kwemawelds anogadzirwa nepakati frequency inverter spot welding michina. Kuburikidza nekutarisa kwekuona, radiographic kuyedzwa, ultrasonic kuyedzwa, magineti particle kuyedzwa, uye nekupinda kuyedza, vagadziri vanogona kuona uye kuongorora hurema hungangoita pasina kukanganisa kutendeseka kwezvinhu zvakasungwa. Nekubatanidza idzi nzira dzeNDT mumaitiro avo ekudzora emhando, vagadziri vanogona kuona kuti welds inosangana nezvinodiwa uye zvakatemwa, zvichitungamira kune zvakachengeteka uye zvakavimbika welded zvimiro uye zvikamu.
