Hanyoyin gwajin da ba a lalata ba da aka saba amfani da su doncarbon karfe bututugwaje-gwaje na ultrasonic (UT), gwajin ƙwayar maganadisu (MT), gwajin shigar da ruwa (PT) da gwajin X-ray (RT).

Amfani da iyakancewar gwajin ultrasonic sune:
Yafi amfani da karfi penetrability da kyau directionality na ultrasonic tãguwar ruwa don tattara tunani na ultrasonic tãguwar ruwa a cikin daban-daban kafofin watsa labarai, da kuma maida da tsangwama tãguwar ruwa a cikin lantarki dijital sakonni a kan allo gane mara lalacewa aibi. Abũbuwan amfãni: babu lalacewa, babu tasiri a kan aikin abin da aka bincika, daidaitaccen hoto na tsarin ciki na kayan da ba a sani ba, aikace-aikace masu yawa na ganowa, wanda ya dace da karafa, ƙananan ƙarfe, kayan haɗin gwiwa da sauran kayan aiki; mafi daidaitaccen matsayi na lahani; kula da lahani na yanki, Babban hankali, ƙananan farashi, saurin sauri, mara lahani ga jikin mutum da muhalli.

Iyakance: Dole ne raƙuman ruwa na Ultrasonic ya dogara da kafofin watsa labarai kuma ba zai iya yaduwa a cikin sarari ba. Raƙuman ruwa na Ultrasonic suna sauƙin ɓacewa kuma suna warwatse cikin iska. Gabaɗaya, ganowa yana buƙatar amfani da masu haɗin gwiwa waɗanda ke haɗa abubuwan ganowa, kuma kafofin watsa labarai kamar (ruwa mai lalata) na gama gari.

Dogaro da iyakoki na gwajin ƙwayar maganadisu sune:
1. Magnetic duban dan tayi ya dace don gano katsewar da ke da ƙananan girman a saman da kuma kusa da saman kayan ferromagnetic, kuma rata yana da kunkuntar da wuya a gani.
2. Binciken kwayoyin halitta na Magnetic na iya gano sassa a yanayi daban-daban, kuma yana iya gano nau'ikan sassa daban-daban.
3. Ana iya samun lahani irin su tsagewa, haɗawa, layin gashi, fararen fata, folds, rufewar sanyi da sako-sako.
4. Magnetic barbashi gwajin ba zai iya gano austenitic bakin karfe kayan da welds welded tare da austenitic bakin karfe electrodes, kuma ba zai iya gane wadanda ba Magnetic kayan kamar jan karfe, aluminum, magnesium da titanium. Yana da wahala a sami ƙulle-ƙulle da folds tare da tarkace mara tushe a saman, ramuka masu zurfi da aka binne, da kusurwoyi ƙasa da 20 ° tare da saman aikin.

Abubuwan da ke tattare da gano masu shiga sune: 1. Yana iya gano abubuwa daban-daban; 2. Yana da babban hankali; 3. Yana da nuni mai mahimmanci, aiki mai dacewa da ƙananan farashin ganowa.
The shortcomings na penetrant gwaji ne: 1. Bai dace da duba workpieces sanya na porous sako-sako da kayan da workpieces tare da m saman; 2. Gwajin shiga ba zai iya gano rarrabuwar lahani kawai ba, kuma yana da wahala a tantance ainihin zurfin lahani, don haka yana da wahala a gano ƙimar ƙima na lahani. Sakamakon ganowa kuma yana da tasiri sosai daga mai aiki.

Aiwatar da iyakoki na gwaji na rediyo:
1. Ya fi dacewa da gano lahani na nau'in girma, kuma yana da sauƙin kwatanta lahani.
2. Abubuwan da ba a iya gani ba suna da sauƙin kiyayewa kuma suna da ganowa.
3. Nuna siffa da nau'in lahani a gani.
4. Rashin lahani Ba za a iya gano zurfin binnewa na lahani ba. A lokaci guda, kaurin ganowa yana iyakance. Fim ɗin mara kyau yana buƙatar wanke shi musamman, kuma yana cutar da jikin ɗan adam, kuma farashin yana da yawa.
