Duban lahani na cikin kayan ko sassa gabaɗaya yana ɗaukar hanyoyin gwaji marasa lalacewa. Gano kuskuren X-ray shine hanyar da aka fi amfani da ita don gwaji mara lahani na bututun ƙarfe na karkace. Siffofin wannan hanyar ganowa haƙiƙa ne kuma kai tsaye, hoton ainihin lokacin ta injinan X-ray, software don yin hukunci ta atomatik, gano lahani, da auna girman lahani.

3. Gwajin ƙarfi na jirgin ruwa: Baya ga gwajin hatimi, ana kuma fuskantar gwajin ƙarfin. Yawanci akwai nau'ikan gwajin hydraulic iri biyu da gwajin huhu. Suna iya gwada yawan weld na tasoshin da bututu masu aiki a ƙarƙashin matsin lamba. Gwajin huhu ya fi hankali da sauri fiye da gwajin ruwa, kuma samfurin da aka gwada ba ya buƙatar zubar da ruwa, musamman ga samfuran da ke da wahalar zubarwa. Amma haɗarin gwaji ya fi gwajin injin ruwa. Yayin gwajin, dole ne a kiyaye daidaitattun matakan tsaro da fasaha don hana hatsarori yayin gwajin.

4. Gwajin ƙwanƙwasa: Don kwantena masu walƙiya da ke adana ruwa ko iskar gas, babu wani lahani mai yawa a cikin walda, kamar fashe fashe, pores, slag, impermeability da sako-sako da ƙungiyar, da sauransu, waɗanda za a iya amfani da su don nemo gwajin ƙima. Hanyoyin gwaji na densification sune: gwajin kananzir, gwajin ruwa, gwajin ruwa, da dai sauransu.

5. Gwajin matsin lamba na Hydrostatic Kowane bututun karfe yakamata a yi gwajin hydrostatic ba tare da yabo ba. Matsakaicin gwajin shine gwargwadon gwajin gwajin P = 2ST / D, inda matsi na gwajin hydrostatic na S shine Mpa, kuma gwajin gwajin hydrostatic yana ƙaddara ta yanayin da ya dace. 60% na fitarwa da aka ƙayyade a daidaitaccen sifa. Lokacin daidaitawa: D <508 ana kiyaye matsa lamba na gwaji don ƙasa da 5 seconds; d ≥ 508 gwajin gwajin ana kiyaye shi don ƙasa da daƙiƙa 10.

6. Gwajin da ba a lalata ba na tsarin karfe bututu welds, karfe shugaban welds da zobe gidajen abinci ya kamata a za'ayi ta X-ray ko ultrasonic gwajin. Don walda mai karkatar da ƙarfe wanda aka isar da shi ta hanyar ruwa na gama gari, 100% X-ray ko gwajin ultrasonic za a yi. Karkataccen welds na bututun ƙarfe masu isar da ruwa na gaba ɗaya kamar ruwa, najasa, iska, tururi mai dumama, da sauransu yakamata a bincika ta X-ray ko ultrasonic. Amfanin duban X-ray shine cewa hoton yana da haƙiƙa, buƙatun ƙwararrun ƙwararru ba su da yawa, kuma ana iya adana bayanan da gano su.
