Mekameka waikano kătahi: āhuatanga me whakamārama

whakaritea te kounga o te fehokotaki'anga e pehea totoka tahuri tahi. I roto i tenei take, kia waiho te hononga mana kore-urutomo, e hanga rangatira i muri i te mahi ki te tono ki te tikanga tirotiro motuhake. I roto i ētahi wā, tukua me whakamātautau waho, kahore mea, engari i roto i te take o ngā hanganga tino kore e kia iti ki te tirohanga ataata. kia kia kō atu te reira i mekameka kătahi tae - tetahi o nga tikanga whai hua tino, e watea ai, me te pono o te tātaritanga o taua pūhui.

Āhuatanga o te tikanga o te manatoko

E pā ana tēnei ara o mekameka whakamātautau ki te capillary, engari hāngai anake i runga i Rapurongoā waho. E ko, e kore e tukua te reira ki te tirohia i te hanganga ā-o te wāhi tahi, rite te ātete ki, hei tauira, i te kitenga koha ultrasonic. Tikanga, Kei te waiho i raro taua whakamātautau ki whakarewa, e pängia ana ki te hangai. I tua atu, ka taea te mana tae ki a koutou tōtika tautuhi puta ki te discontinuities mata.

Ki te whakaute ki te parau tumu whakaū, kei te hāngai ki runga ki te tūtohutanga o te whakarewa ki te taunekeneke ki te rauemi tae penetrant. Anga ke ki te tātaritanga whakapono rongonui rite mōhiohio mana, whakamahia e te reira i kore āhuatanga workpiece mata, a ka whakapataritari huringa i ritenga o te hanganga o ngā matū. I runga i nga tukanga o te tikanga tirohanga penetrant matū, me te tae e hāngai ana te, e taea ana ki te tukatuka mōhiohio e pā ana ki te huringa me te putanga ki te whakarato i raraunga i runga i te hapehape tāutuhia o te whakarewa.

te tikanga iho rite taua te uaua whakamahia anake. Ko te tikanga kua whakamahia te reira i roto i te whakamātautau matatini whānui - tahi ki ultrasound. Tuatahi, me tātari e koe te tae, me te tirohanga ka ultrasonic.

rauemi ka whakamahia

Ka rite ki kua whakahuatia, ko oti waho te whakamahi o ngā matū motuhake te tirohanga. huinga Paerewa mō te tae penetrant ngā toru ngā momo o ngā wāhanga: te tohu penetrant, e tamâ me te kaiwhakawhanake. E ko, whakahohe mana o te tūtohutanga tae te tika ki te maimoatanga e toru-wāhanga o te rohe mahi. I ia wāhanga o te rauemi motuhake whakamahia.

Penetrants - he, i roto i te meka, colorants, e ai kia te aroaro i roto i te puka rerekē. te tono hoki matū maroke, engari me tomo ratou whakamahi me te atu ngā mahi, maimoatanga waiariki ranei i konatunatua ki te wai. penetrants E tika ana hoki te ngā penetrant whakarewa waikano tīpako e hāngai ana i runga i te maha o ngā āhuatanga mahi. Tangohia ki pūkete, i roto i ngā, ahi resistance, me te tāoke taiao, te hiahia mo te horoi muri o te okotahi, a na i runga i. D.

Whakaritenga ki te wāhi o te mana

Ko taea te kawe i mahi tirohanga anake i roto i te ruma rite rawa. He mea nui ki te tango ki roto ki pūkete nga whakaritenga wāhi taputapu kōrero hoki ki ngā rangi, te tautoko hangarau, a na i runga i. D. Me hā me te ruma i kahore mura tuwhera wera nui ranei. kia whānui, me te rohe, tata ki te pae o rama pokanga Me tiaki i wera Lighting.

I roto i ngā, mo te tono i nga pu penetrant taua kia whakamahia ai, kēne rehu, brushes me t. D.

Whakapaia te turanga tui

Kei te rite ano te wahi hononga mō ngā mahi tirohanga. Ki te mea kua whakahuatia te mata roughness contamination ranei, ka taea e koe te whakamahi i te rauemi pai me te hua ngāwari whāwhā. Next, whakamana degreasing te. Hoki tenei mahi, ka taea e koe te whakamahi i tetahi o te huinga tirotiro o ngā wāhanga, engari he mea nui e te whakaratohia reira pānga degreasing, a tae noa pai - ki te whakapiki ake i tūtohutanga mana. E kore e tūtohu ana ki te whakamahi mo te taua take, karahīni, engari ka taea e koe te whakamahi i penehīni me te hauwaiwaro. Ki te kahore he hā ora i roto i te ruma, whakamana te degreasing te anake i runga i te pūtake o wairewa waiwai o te paura waihanga tikanga he kukū iti. Ki te whakamahere koe ki te tae penetrant wahi iti-rahi, ko reira taea ki te tono me te oti rumaki i roto i te degreasing hanganga.

Ano, whakakitea ki tae mekameka kătahi hua tika optimally, kua ki te taupoki ana i te rohe āhua nui o te mua ia paparanga angitu. Ko e tika ana ki te meka e ka memeha ia paparanga hou wahi mua aratau, faka'ehi'ehi mei whakawhitinga ohorere, me te sagging, e taea te mohio a rite kapiti teka tenei.
