Hanyar dubawa ta jiki ita ce amfani da wasu al'amura na zahiri don aunawa ko hanyoyin dubawa. Material ko workpiece duba lahani na ciki, gabaɗaya ta amfani da hanyoyin gano lahani marasa lalacewa. Gano aibi mara lalacewa na yanzu na gano aibi na ultrasonic, gano aibi na ray, gano shigar ciki, gano aibi na maganadisu.
① Ganewar Ray
Gane lahani na Ray shine amfani da radiation zai iya shiga cikin kayan kuma a cikin kayan yana da halayyar attenuation don gano lahani a cikin hanyar gano kuskure. Dangane da haskoki daban-daban da aka yi amfani da su wajen gano aibi, ana iya raba su zuwa gano aibi na X-ray, gano aibi na γ-ray, gano aibi mai ƙarfi mai ƙarfi. Saboda hanyar nuna lahani daban-daban, kowane ganowar hasashe ya kasu kashi-kashi hanyar ioniization, hanyar kallon allo mai kyalli, hanyar daukar hoto da hanyar talabijin na masana'antu. Ana amfani da duban Ray galibi don gwada ɓarna na ciki na weld, unwelded, porosity, slag da sauran lahani.
②UGane aibi na ltrasonic
Duban dan tayi a cikin karfe da sauran kayan aikin watsa labarai na uniform, saboda haɗin kai a cikin kafofin watsa labaru daban-daban zai haifar da tunani, don haka ana iya amfani da shi don duba lahani na ciki. Binciken Ultrasonic na kowane kayan walda, kowane ɓangare na lahani, kuma yana iya zama mafi mahimmanci don gano wurin lahani, amma yanayin lahani, siffar da girman ya fi wuya a tantance. Don haka ana amfani da gano aibi na ultrasonic sau da yawa tare da duban haske.
③ Binciken Magnetic
Binciken Magnetic shine amfani da maganadisu na filin maganadisu na sassan ƙarfe na ferromagnetic da aka samar ta hanyar ɗigon maganadisu don gano lahani. Dangane da hanyoyi daban-daban na auna zubin maganadisu, ana iya raba su zuwa hanyar magnetic foda, hanyar shigar da maganadisu da kuma hanyar rikodin maganadisu, wanda aka fi amfani da hanyar foda na maganadisu.
Gano aibi na Magnetic zai iya samun lahani kawai a saman da kuma kusa da saman ƙarfen maganadisu, kuma yana iya yin ƙididdige ƙididdiga na lahani, kuma yanayi da zurfin lahani ba za a iya ƙididdige su ba bisa ga gogewa.
④ Gwajin shigar ciki
Gwajin shigar ciki shine don amfani da yuwuwar wasu ruwaye da sauran kaddarorin jiki don nemowa da nuna lahani, gami da gwajin launi da gano aibi biyu, ana iya amfani da su don bincika lahanin saman ferromagnetic da maras ferromagnetic abu.
Abin da ke sama shine samfuran bakin karfe da ke sarrafa abubuwan dubawa na walda bakin karfe ciki har da daga zanen zane zuwa samfuran bakin karfe daga duk tsarin samar da hanyoyin binciken walda bakin karfe da kwatance.
