Mumagetsi ekuchengetera nzvimbo welding michina, kuve nechokwadi chemhando uye kutendeseka kwemajoini e weld kwakakosha zvakanyanya.Kuti uite izvi, nzira dzakasiyana-siyana dzekuongorora dzinoshandiswa kuongorora majoini e weld yehurema, senge kusakwana kusanganisa, kutsemuka, kana porosity.Ichi chinyorwa chinoongorora maitiro akasiyana-siyana ekuongorora majoini e weld mumagetsi ekuchengetera nzvimbo welding michina, ichipa vashandisi maturusi akakosha ekuchengetedza emhando yepamusoro welds.
- Kuongorora Kwekuona: Kuongorora kwekuona ndiyo inonyanya kukosha uye inowanzoshandiswa nzira yekuongorora majoini e weld.Vashandi vanotarisa nzvimbo yeweld kune chero hurema hunooneka, hwakadai sekusakwana kusanganiswa, kusarongeka kwepasi, kana discontinuities.Iyi nzira inoda ziso rakadzidziswa uye yakakwana mamiriro ekuvhenekesa kunyatsoona zvingangoitika nyaya.
- Matekiniki eKuedza Kusina Kuparadza (NDT): a.Ultrasonic Testing: Ultrasonic bvunzo inoshandisa yakakwirira-frequency mafungu eruzha kuti aone kukanganisa kwemukati kana kukanganisa mumajoini e weld.Ultrasonic masaisai anotapurirwa kuburikidza nejoin ye weld, uye masaisai anoratidzwa anoongororwa kuti aone chero abnormalities.Iyi tekinoroji inonyanya kushanda pakuona pasi pepasi makatsemuka kana porosity.
b.Radiographic Testing: Kuongororwa kweRadiographic kunosanganisira kupfuudza maX-rays kana gamma rays kuburikidza nejoinhi reweld uye kutora mufananidzo pafirimu kana dhijitari.Iyi nzira inogona kuratidza hurema hwemukati, hwakadai sekupinda kusina kukwana kana voids.Radiographic kuyedzwa inonyanya kubatsira kune akakora kana akaomarara weld majoini.
c.Magnetic Particle Testing: Magnetic particle yekuongorora inoshandiswa kuongorora ferromagnetic zvinhu.A magnetic field inoshandiswa kune weld joint, uye magnetic particles inoshandiswa pamusoro.Chero kukanganisa-kupwanya kwepamusoro kuchaita kuti magineti aungane, zvichiratidza kuvepo kwekukanganisa.
d.Dye Penetrant Testing: Dhayi inopinda muyedzo inoshandiswa kuona kuremara kwepamusoro mumajoini e weld.Dhayi ine ruvara inoshandiswa pamusoro, uye mushure menguva yakatarwa, dhayi yakawandisa inobviswa.Mugadziri anozoiswa, iyo inokwevera dhayi yakabatwa kubva pane chero hurema hwepamusoro, ichiita kuti ionekwe.
- Kuedza Kuparadza: Mune zvimwe zviitiko, kuedza kunoparadza kunodiwa kuti uongorore mhando yeweld joint.Izvi zvinosanganisira kubvisa chikamu chemuenzaniso chejoint ye weld uye kuchiisa kumiyedzo yakasiyana siyana, senge tensile test, kukotama, kana kuomarara kuyedzwa.Kuparadza kuyedzwa kunopa ruzivo rwakadzama nezve weld joint's mechanical properties uye inogona kuratidza yakavanzwa hurema.
Kuongorora majoini e weld mumagetsi ekuchengetedza nzvimbo welding machina kwakakosha pakuona weld mhando uye kurongeka kwechimiro.Nekushandisa yekutarisa yekuona, isiri-inoparadza nzira dzekuyedza (senge ultrasonic bvunzo, radiographic kuyedza, magineti particle bvunzo, uye dhayi inopinda mukati mekuyedza), uye, kana zvichidikanwa, inoparadza kuyedza, vanoshanda vanogona kunyatso ongorora majoini e weld kuti akaremara.Kuita chirongwa chakazara chekuongorora kunobatsira kuchengetedza yakakwira mwero wemhando uye kuvimbika mukuchengetedza simba nzvimbo welding application.Kuongororwa nguva dzose kunogonesa kuzivikanwa nekukurumidza uye kugadzirisa chero nyaya, zvichitungamira kune yakagadziridzwa weld mhando uye yakazara welding kuita.
