Hanyoyin Gwaji marasa lalacewa a cikin Injin Welding na Matsakaicin Mitar Inverter?

Gwajin marasa lalacewa (NDT) yana taka muhimmiyar rawa wajen tabbatar da inganci da amincin walda da injinan walda tabo mai matsakaicin mitar inverter ke samarwa. Ta hanyar amfani da hanyoyin NDT daban-daban, masana'antun na iya gano lahani da lahani a cikin walda ba tare da haifar da lahani ga abubuwan walda ba. Wannan labarin yana bincika hanyoyin gwajin gama-gari na gama gari waɗanda aka yi amfani da su a cikin inverter spot waldi inverter da kuma tattauna mahimmancin su a cikin tabbacin inganci.

1. Duban Kayayyaki: Duban gani hanya ce ta asali amma tana da mahimmanci ta NDT wacce ta ƙunshi duban walƙiya da wuraren da ke kewaye don rashin daidaituwar saman ƙasa, yankewa, ko wasu lahani na bayyane. ƙwararrun masu duba suna amfani da isassun kayan aikin haske da haɓakawa don bincika walƙiya sosai da gano duk wata alamar al'amura masu inganci, kamar tsagewa, porosity, ko rashin isassun haɗuwa.
2. Gwajin Radiyo (RT): Gwajin rediyo yana amfani da hasken X-ray ko gamma don bincika tsarin ciki na walda. A cikin wannan hanyar, fim ɗin rediyo ko mai ganowa na dijital yana ɗaukar radiyon da aka watsa, yana samar da hoton da ke bayyana lahani na ciki, kamar ɓoyayyiya, haɗawa, ko rashin shiga. Gwajin radiyo yana ba da haske mai mahimmanci game da inganci da amincin walda, musamman a cikin kauri ko hadaddun walda.
3. Gwajin Ultrasonic (UT): Gwajin Ultrasonic yana amfani da igiyoyin sauti masu tsayi don gano lahani na ciki da auna kaurin walda. Ta hanyar aika raƙuman ruwa na ultrasonic cikin yankin walda da kuma nazarin siginar da aka nuna, kayan aikin UT na iya gano lahani kamar fasa, ɓoyayyiya, ko haɗakar da ba ta cika ba. UT yana da amfani musamman don gano lahani na ƙasa da kuma tabbatar da ingancin walda a cikin aikace-aikace masu mahimmanci.
4. Gwajin Magnetic Particle (MT): Gwajin ƙwayar maganadisu hanya ce ta farko da ake amfani da ita don gano lahani na kusa da ƙasa a cikin kayan ferromagnetic. A cikin wannan fasaha, ana amfani da filin maganadisu zuwa wurin walda, kuma ana amfani da ɓangarorin ƙarfe (ko dai busassu ko rataye a cikin ruwa). Barbashi suna taruwa a wuraren da yatsan ruwan maganadisu ke haifar da lahani, yana sa su ganuwa ƙarƙashin ingantattun yanayin haske. MT yana da tasiri don gano fashewar saman ƙasa da sauran abubuwan da aka dakatar a cikin walda.
5. Gwajin Penetrant (PT): Gwajin Penetrant, wanda kuma aka sani da duban shigar rini, ana amfani da shi don gano lahani a cikin walda. Tsarin ya ƙunshi shafa rini na ruwa zuwa saman walda, ƙyale shi ya shiga cikin kowane lahani na saman ta hanyar aikin capillary. Bayan ƙayyadadden lokaci, za a cire rini da ya wuce gona da iri, kuma ana shafa mai haɓakawa don zana rini ɗin da aka kama. Wannan hanya tana bayyana alamun fashe, porosity, ko wasu lahani masu alaƙa da saman.

Hanyoyin gwaje-gwaje marasa lalacewa suna taka muhimmiyar rawa wajen kimanta inganci da amincin walda waɗanda ke samar da injunan walƙiya ta matsakaicin mitar inverter. Ta hanyar dubawa na gani, gwajin hoto, gwajin ultrasonic, gwajin ƙwayar maganadisu, da gwajin shiga, masana'antun na iya ganowa da tantance lahani masu yuwuwar ba tare da lalata amincin abubuwan waldadin ba. Ta hanyar haɗa waɗannan hanyoyin NDT cikin tsarin sarrafa ingancin su, masana'antun za su iya tabbatar da cewa welds sun cika ka'idojin da ake buƙata da ƙayyadaddun bayanai, wanda ke haifar da amintattun sifofi da abubuwan haɗin welded.
