Hanyoyin gwajin da ba su lalacewa da aka fi amfani da su: Gwajin ultrasonic (UT), gwajin ƙwayar maganadisu (MT), gwajin shigar da ruwa (PT) da gwajin X-ray (RT).
Gwajin Ultrasonic
UT (Gwajin Ultrasonic) yana ɗaya daga cikin hanyoyin gwajin masana'antu marasa lalacewa. Lokacin da igiyar ultrasonic ta shiga cikin wani abu kuma ya ci karo da wani lahani, ɓangaren sautin za a nuna, kuma mai watsawa da mai karɓa na iya bincikar igiyar da aka nuna, kuma ana iya gano lahanin daidai. Kuma yana iya nuna matsayi da girman lahani na ciki, auna kauri na kayan, da dai sauransu.
Amfanin gwajin ultrasonic:
1. Babban ikon shiga ciki, alal misali, zurfin ganowa mai tasiri a cikin karfe zai iya kaiwa fiye da mita 1;
2. Don lahani na tsari irin su fasa, interlayers, da dai sauransu, ganewar ganewa yana da girma, kuma za a iya auna zurfin da girman girman lahani;
3. Kayan aiki yana šaukuwa, aikin yana da lafiya, kuma yana da sauƙin gane dubawa ta atomatik.
kasawa:
Ba abu mai sauƙi ba ne don duba kayan aiki tare da siffofi masu rikitarwa, kuma saman da za a duba yana buƙatar samun wani nau'i na santsi, kuma rata tsakanin binciken da saman da za a duba dole ne a cika shi da coupplant don tabbatar da isassun haɗakar sauti.
Gwajin Kwayoyin Magnetic
Da farko, bari mu fahimci ƙa'idar gwajin ƙwayar maganadisu. Bayan da ferromagnetic abu da workpiece suna magnetized, saboda kasancewar katsewa, da Magnetic filin Lines a kan surface da kuma kusa da surface na workpiece suna cikin gida gurbatacce, sakamakon yayyo Magnetic filin, wanda ya sha da Magnetic foda amfani a kan. surface na workpiece, da kuma Forms wani bayyane Magnetic filin karkashin dace haske. burbushi, ta haka yana nuna wuri, siffa da girman katsewar.
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.

gwajin shigar ruwa
Babban ka'idar gwajin shigar da ruwa shine cewa bayan saman ɓangaren an rufe shi da dyes mai kyalli ko rini masu launi, mai shiga zai iya shiga cikin lahani buɗe saman saman ƙarƙashin aikin capillary na wani lokaci; bayan cire wuce haddi mai ratsa jiki a saman sashin, ana amfani da mai haɓakawa a saman sashin.
Hakazalika, a ƙarƙashin aikin capillary, wakilin hoto zai jawo hankalin ruwan shigar da ke riƙe a cikin lahani, kuma ruwan da ke shiga ya sake komawa cikin ma'aunin hoto, kuma a ƙarƙashin wata hanyar haske (hasken ultraviolet ko farin haske), alamar. Ruwan da ke shiga a cikin lahani yana nunawa, (rawaya-kore mai haske ko ja mai haske), don gano ilimin halittar jiki da rarraba lahani.
Fa'idodin gwajin shiga ciki sune:
1. Yana iya gano abubuwa daban-daban;
2. Babban hankali;
3. Nuni mai mahimmanci, aiki mai dacewa da ƙananan farashin ganowa.
Abubuwan da ke tattare da gwajin shiga ciki sune:
1. Ba dace da duba workpieces sanya na porous sako-sako da kayan da workpieces tare da m saman;
2. Gwajin shigar ciki kawai zai iya gano rarrabuwar lahani ne kawai, kuma yana da wahala a tantance ainihin zurfin lahani, don haka yana da wahala a ƙididdige ƙima na lahani. Sakamakon ganowa kuma yana da tasiri sosai daga mai aiki.
Binciken X-ray
Na karshe, gano ray, shi ne saboda X-ray za a bace bayan wucewa ta cikin abin da ya haskaka, da kuma daban-daban kayan da daban-daban masu kauri daban-daban da adadin sha daban-daban a gare su, da kuma mummunan fim da aka sanya a daya gefen abin da ya haskaka. wanda zai bambanta saboda bambancin hasken hasken. Ana samar da zane-zane masu dacewa, kuma masu dubawa za su iya yanke hukunci ko akwai lahani a cikin abin da yanayin lahani bisa ga hoton.
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 shi ne cewa zurfin da aka binne na lahani ba zai iya samuwa 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.
Gabaɗaya, gano lahani na ultrasonic da X-ray sun dace don gano lahani na ciki; Daga cikin su, ultrasonic ya dace da sassan da siffar yau da kullum fiye da 5mm, kuma X-ray ba zai iya gano zurfin binne lahani ba kuma yana da radiation. Magnetic barbashi da mai shiga gwaji sun dace don gano lahani na abubuwan da aka gyara; A cikin su, gwajin ƙwayar maganadisu yana iyakance ga gano kayan maganadisu, kuma gwajin shiga ya iyakance ga gano lahani buɗe saman saman.
