1. Kuongororwa kwekuonekwa kwezvigadzirwa zvegokora: kazhinji, kuongorora kwekuona ndiyo nzira huru.Kuburikidza nekutariswa kwechitarisiko, zvinoonekwa kuti weld chitarisiko chakaremara chewelded elbow pombi fittings inowonekwa ne5-20 nguva yekukudza girazi dzimwe nguva.Zvakadai se undercut, porosity, weld bead, surface crack, slag inclusion, welding penetration, etc. The whole dimension of weld inogonawo kuyerwa ne weld detector kana template.

2. NDT yegorofu fittings: tarisa kukanganisa kwakadai sekuiswa kwe slag, gomba remhepo uye kuputika mu weld.X-ray kuongorora ndiko kushandiswa kwe X-ray kutora mapikicha e weld, maererano nemufananidzo wakashata kuti uone kana pane zvikanganiso mu weld, nhamba uye rudzi rwezvakaremara.Parizvino, X-ray yekuyedza, ultrasonic bvunzo uye magineti yekuyedza inoshandiswa zvakanyanya.Zvino maererano nechigadzirwa hunyanzvi zvinodiwa, tarisa kana weld inokodzera.Panguva ino, iyo inoratidzwa wave inoonekwa pachiratidziri.Nekuenzanisa uye kuona aya mafungu anoratidzwa uye masaisai akajairwa, saizi nenzvimbo yehurema inogona kutsanangurwa.Ultrasonic yekuongorora iri nyore kupfuura X-ray yekuongorora, saka yakashandiswa zvakanyanya.Nekudaro, kuongororwa kwe ultrasonic kunogona kungotongwa nechiitiko chekushanda uye haigone kusiya hwaro hwekuongorora.Kana iyo ultrasonic danda inopfuudzwa kune simbi mhepo interface, inoramba uye ichipfuura nepakati weld.Kana pane kukanganisa mu weld, iyo ultrasonic beam icharatidzwa pane probe uye bheya.Magnetic inspection inogona zvakare kushandiswa kune hurema hwemukati uye madiki madiki akatsemuka asina kudzika kubva kune weld pamusoro.

3. Mechanical property test yegokora fittings: nondestructive testimendi inogona kuwana hurema hwemukati we weld, asi haigone kutsanangura ma mechanic zvimiro zvesimbi mukupisa kunokanganisa nzvimbo ye weld.Dzimwe nguva tensile, kukanganisa uye kukotama bvunzo zvinodiwa kune akasungwa majoini.Iyi miedzo yakaitwa pabhodhi.Iyo ndiro yekuyedza inofanirwa kuve yakashongedzwa neiyo longitudinal seam yehumburumbira kuti ive nechokwadi chakafanana mamiriro ekuvaka.Ipapo iyo mechanical properties ye test plate yakaedzwa.Mukugadzira kunoshanda, iyo chete yekubatanidza yewelding yegiredhi nyowani yesimbi inoedzwa mune izvi.

4. Hydrostatic test uye pneumatic test ye elbow fittings: nokuda kwezvikepe zvekumanikidzika zvinoda kuiswa chisimbiso, hydrostatic test uye pneumatic test inotarisirwa kutarisa kuvhara uye kudzvinyirira kutakura simba re welds.Iyo nzira ndeyekuisa jekiseni mugaba musimba rekushanda remvura kana 1.25-1.5 nguva yekushanda kwegasi (yakawanda yemhepo) kwenguva yakati rebei, wozoongorora kudonha kwekumanikidza mumudziyo, uye ongorora kana paine chinhu chipi nechipi chinobuda, kuitira kuti uone kana weld inokodzera.
