Mushure mekupedza iyo welding process uchishandisa nut spot welding muchina, zvakakosha kuita post-weld ongororo kuti ive nechokwadi chemhando yeweld uye kutevedza kune yakatarwa zviyero. Nzira dzinoverengeka dzekuongorora dzinoshandiswa kuongorora kuvimbika uye kusimba kwemajoini e weld. Ichi chinyorwa chinopa tarisiro yeakasiyana nzira dzekuongorora dzinoshandiswa pamashure-weld bvunzo mune nut spot welding mashandiro.
- Kuongorora Kwekuona: Kuongorora kwekuona ndiyo inonyanya kukosha uye yekutanga nzira yekuongorora weld mhando. Inspector ane ruzivo anoongorora majoini e weld achishandisa ziso rakashama kuti aone zvikanganiso zvinoonekwa senge kusarongeka kwepasi, weld bead kufanana, uye zviratidzo zvekusakwana fusion kana porosity. Iyi nzira isingaparadzi yekuongorora inopa mhinduro yakakosha pakuonekwa kwese weld uye inogona kuratidza kuvepo kwehurema hunogona kuitika.
- Matekiniki eKuedza Kusina Kuparadza (NDT): a. Ultrasonic Testing (UT): UT inoshandisa mafungu e-high-frequency sound kuti iongorore welds yehurema hwemukati. Inogona kuona discontinuities, zvakadai sekutsemuka kana kushaya fusion, mukati meweld joint pasina kukonzera kukanganisa kune chikamu. UT inonyanya kubatsira pakuona zvakavanzwa kuremara mune zvakakosha welds.
b. Radiographic Testing (RT): RT inosanganisira kushandiswa kweX-rays kana gamma rays kuwana mifananidzo yeweld joint yemukati chimiro. Iyi nzira inobvumira vanoongorora kuti vaone kukanganisa kwemukati, voids, uye inclusions iyo inogona kunge isingaonekwe panguva yekutarisa kwekuona.
c. Magnetic Particle Testing (MT): MT inonyanya kushandiswa kuongorora ferromagnetic zvinhu. Zvinosanganisira kushandisa magineti uye magineti particles kune weld surface. Zvimedu zvinoungana panzvimbo dzine hurema, zvichiita kuti zvionekwe nyore.
d. Liquid Penetrant Testing (PT): PT inoshandiswa kuona kukanganisa-kupwanya kwepamusoro mune zvisiri-porous zvinhu. Mvura inopinza inoiswa kune weld surface, uye yakawandisa inopinda inopukuta. Iyo yasara inopinda inozoratidzwa kuburikidza nekushandiswa kwemugadziri, ichiratidza chero hurema hwepamusoro.
- Inoparadza Muedzo (DT): Muzviitiko apo weld mhando inofanirwa kuongororwa zvine simba, nzira dzekuyedza dzinoparadza dzinoshandiswa. Miedzo iyi inosanganisira kubvisa chikamu chejoin ye weld kuti uongorore michina yayo uye simba. Nzira dzakajairika dzeDT dzinosanganisira: a. Tensile Testing: Inoyera kusimba kwejoint weld uye ductility. b. Bend Testing: Inoongorora kuramba kwe weld pakutsemuka kana kutyoka pasi pekukotama kushushikana. c. Macroscopic Examination: Inosanganisira kukamura uye kupukuta iyo weld kuongorora chimiro chayo uye weld kupinda.
Kuita post-weld inspections uchishandisa nzira dzakasiyana-siyana kwakakosha kuti uve nechokwadi chekuvimbika uye kunaka kwemajoini e weld akagadzirwa nemuchina we nut spot welding. Musanganiswa wekutarisa kwekuona, kusaparadza nzira dzekuyedza, uye, kana zvichidikanwa, kuyedza kunoparadza kunopa ruzivo rwakakwana mukutendeseka kweiyo weld uye kuomerera kune indasitiri zviyero. Nekuita idzi nzira dzekuongorora, nyanzvi dzewelding dzinogona kuvimbisa kuchengetedzeka uye kuita kwezvikamu zvakashongedzwa mumashandisirwo akasiyana siyana.
