Gwaje-gwajen Weld na Bayan-Weld don Welding Spot Spot: Binciken Yiwuwar

Bayan kammala aikin walƙiya tabo na goro, yana da mahimmanci don kimanta inganci da amincin welds.Gudanar da gwaje-gwaje bayan walda yana ba da haske mai mahimmanci game da kaddarorin injin walda, ƙarfi, da amincin tsarin walda.Wannan labarin ya bincika dabaru daban-daban na gwaji waɗanda za a iya yi don tantancewa da tantance walda tabo na goro.

1. Gwajin tensile: Ana amfani da gwajin juzu'i da yawa don kimanta kaddarorin injina da ƙarfin haɗin gwiwa.A cikin wannan gwaji, jerin samfuran welded ana fuskantar dakaru masu ƙarfi har sai an gaza.Sakamakon yana ba da bayani game da ƙarfin juzu'i na ƙarshe, ƙarfin yawan amfanin ƙasa, haɓakawa, da halayen raunin walda, yana taimakawa tantance aikinsu gabaɗaya da dacewa ga aikace-aikacen da aka yi niyya.
2. Gwajin Shear: Gwajin juzu'i an ƙera shi musamman don kimanta ƙarfi da juriya na walda tabo.Wannan gwajin ya ƙunshi ƙaddamar da samfuran welded zuwa ƙarfin shearing har sai gazawar ta faru.Bayanan da aka samu, gami da ɗaukar nauyi, ƙaura, da yanayin gazawa, yana ba da damar tantance ƙarfin juzu'in walda da ikonsa na jure kayan aiki.
3. Binciken Microstructural: Binciken ƙananan ƙananan yana ba da damar bincika tsarin ciki na weld kuma yana ba da haske game da tsarin hatsi, yankin da zafi ya shafa, da duk wani lahani ko yankewa.Za a iya amfani da fasaha irin su metallography, microscopy, da scanning electron microscopy (SEM) don dubawa da kuma nazarin ƙananan ƙirar walda, suna taimakawa wajen tantance ingancinsa da gano duk wata matsala da za ta iya shafar aikinta.
4. Gwajin taurin: Ana yin gwajin taurin don auna rarraba taurin a cikin yankin walda.Wannan gwajin yana taimakawa kimanta ingancin tsarin walda da tantance kasancewar kowane yanki mai laushi ko wuya wanda zai iya tasiri ƙarfinsa da dorewa.Za a iya amfani da dabaru kamar Vickers ko gwajin hardness na Rockwell don ƙididdige ƙimar taurin walda da gano duk wani bambance-bambance a cikin haɗin gwiwa.
5. Gwajin mara lalacewa (NDT): Dabarun gwaji marasa lalacewa, kamar gwajin ultrasonic, gwajin eddy na yanzu, ko gwajin hoto, ana iya amfani da su don tantance ingancin ciki na welds ba tare da haifar da lalacewa ba.Waɗannan hanyoyin na iya gano lahani, kamar tsagewa, ɓoyayyiya, ko haɗawa, tabbatar da walda sun cika ƙa'idodin da ake buƙata da ƙayyadaddun bayanai.

Gudanar da gwaje-gwaje bayan walda yana da mahimmanci don kimanta inganci, ƙarfi, da amincin tsarin walda tabo na goro.Gwajin juzu'i, gwajin juzu'i, bincike na microstructural, gwajin taurin, da gwaji marasa lalacewa dabaru ne masu mahimmanci waɗanda ke ba da mahimman bayanai game da kaddarorin injin walda, tsarin ciki, da yuwuwar lahani.Ta hanyar yin waɗannan gwaje-gwajen, injiniyoyi da masu walda za su iya tabbatar da waldar sun cika ka'idodi da buƙatun da ake so, ta yadda za su tabbatar da amincin su da aikin su a aikace-aikacen ainihin duniya.
