I te hoko rauemi kowiri tira mō ngā kaupapa ahumahi, hangahanga, hangahanga rānei, he mea nui te manatoko i te kounga me te tutuki o aua rauemi. Koinei te wāhi eNgā Pūrongo Whakamātautau Mira (MTR)ka whai wāhi mai. Ka whakaratohia e ngā MTR ngā tuhinga nui e whakaū ana kei te tutuki te maitai kore waikura i ngā paerewa, ngā whakaritenga, me ngā paearu mahi e hiahiatia ana. Heoi, mō te tini o ngā kaihoko, ngā miihini, ngā kaiwhakahaere kaupapa rānei, he uaua pea te mārama ki te pānui me te whakamārama i tētahi MTR i te tīmatanga.
I roto i tēnei tuhinga, ka ārahi mātou i a koe i ngā kaupapa matua o te pānui i ngā MTR kowiri tira, ka whakamārama i te tikanga o ngā wāhanga matua, me te whakamārama he aha i hiranga ai ēnei mō te angitu o tō kaupapa.
He aha te Pūrongo Whakamātautau Mira?
He tuhinga whakaū kounga te Pūrongo Whakamātautau Mira e whakaratohia ana e te kaihanga maitai kore waikura. E whakaatu ana kua hangaia, kua whakamatautauria, kua tirotirohia hoki te rauemi i tukuna mai i runga anō i ngā paerewa e tika ana (pēnei i te ASTM, ASME, EN rānei).
I te nuinga o te wā ka haere tahi ngā MTR me ngā pereti maitai kore waikura, ngā paipa, ngā ngongo, ngā pae, me ngā taputapu, ā, hei taunakitanga mō te hanganga o te rauemi, ngā āhuatanga hangarau, me te tutuki i ngā whakaritenga ota.
At sakysteel, ka tukuna ia hua kowiri tira me tētahi MTR katoa, ka taea te whai, kia mau ai te rangimarie o te hinengaro me te kawenga mō ā mātou kiritaki.
He aha te Hiranga o ngā MTR
Mā ngā MTR ka whakawhirinaki koe ki ngā rauemi e whiwhi ana koe:
-
E tutuki ana te taumata kua tohua (pēnei i te 304, 316, 904L rānei)
-
E tutuki ana ki ngā paerewa ahumahi, kaupapa rānei
-
Kua paahitia ngā whakamātautau matū me ngā whakamātautau miihini e tika ana
-
Ka taea te whai i tōna pūtake hei whakapūmau i te kounga
He mea nui ēnei i roto i ngā rāngai pēnei i te hinu me te hau, te tukatuka matū, te hanga taputapu kai, me te hanganga hanganga ina kore e taea te whiriwhiri i te pono o ngā rauemi.
Ngā Wāhanga Matua o te MTR Kowiri tira
1. Tau Wera
He tohu ahurei te tau wera mō te puranga maitai i hangaia ai tō rauemi. Ka hono tēnei tau i te hua ki te puranga me ngā hua whakamātautau tuturu i tuhia ki te mira.
2. Whakatakotoranga Rauemi
E whakamārama ana tēnei wāhanga i te paerewa e tutukihia ana e te rauemi, pērā i te ASTM A240 mō te pereti, te ASTM A312 rānei mō te paipa. Tērā pea ka uru atu ētahi atu waehere mēnā kua whakamanahia kia rua ngā whakaritenga.
3. Tau me te Momo
I konei ka kite koe i te kounga o te maitai kore waikura (hei tauira, 304, 316L, 430) me ētahi wā te āhua, te whakaotinga rānei (pēnei i te whakamahana, i te oro rānei).
4. Te Hanganga Matū
E whakaatu ana tēnei ripanga i te ōrau tika o ngā huānga matua pērā i te chromium, te nickel, te molybdenum, te waro, te manganese, te silicon, te phosphorus, me te whanariki. E whakaatu ana tēnei wāhanga kua tutuki i te rauemi ngā herenga matū e hiahiatia ana mō te taumata kua tohua.
5. Ngā Āhuatanga Mīhini
Kua whakarārangihia ki konei ngā hua whakamātautau ā-mīhini pērā i te kaha kume, te kaha tuku, te roa, me te pakeke. E whakaū ana ēnei hua kua tutuki ngā āhuatanga mahi o te maitai i ngā whakaritenga o te paerewa.
6. Ngā Hua Whakamātautau mō ngā Āhuatanga Tāpiri
I runga anō i te ota, ka taea hoki e ngā MTR te ripoata i ngā hua mō ngā whakamātautau pānga, ngā whakamātautau waikura (pēnei i te ātete ki te poka), ngā whakamātautau kore-whakangaro rānei (pēnei i te ultrasonic, te X-ray rānei).
7. Ngā Tiwhikete me ngā Whakaaetanga
Ko te MTR ka hainatia i te nuinga o te wā e tētahi māngai whai mana o te mira, hei whakamana i te tika o te pūrongo. Tērā pea ka whakaatuhia hoki ngā tohu tirotiro a te hunga tuatoru, ngā tohu tiwhikete rānei mēnā e hiahiatia ana.
Me pēhea te Tirotiro Whakawhiti i ngā Raraunga MTR
Ina arotakehia he MTR, me:
-
Manatokohia te tau werae ōrite ana ki te mea kua tohua ki tō rauemi
-
Whakaūtia te hanganga matūe tutuki ana i ngā whakaritenga o tō kaupapa
-
Tirohia ngā āhuatanga ā-pūkahae ai ki ngā whakaritenga hoahoa
-
Me whakarite kia tutuki ngā paerewa e hiahiatia aname ngā tuhipoka motuhake katoa
-
Arotake i te āheinga whaihei whakaū i ngā tuhinga katoa mō ngā arotake kounga
At sakysteel, ka āwhina mātou i ngā kiritaki ki te whakamārama i ngā MTR, me te whakarite kia oti, kia tika hoki ngā tuhinga katoa i mua i te tuku.
Ngā Hapa MTR Noa hei Ārai
-
Te whakaaro kia tutuki ngā whakaritenga me te kore e tirotiro i ngā raraungaKaua rawa e mahue te arotake i ngā raraunga matū me ngā raraunga ā-pūkaha.
-
Te kore aro ki te taurite o te weraKa taea e tēnei te waihanga i ngā āputa whai i roto i ngā tono nui.
-
Te tirotiro i ngā tāmati tiwhikete, ngā waitohu rānei e ngaro anaKāore pea e tika ana kia tirohia he MTR kāore anō kia hainatia, kāore rānei i oti.
Puritia tonutia ngā MTR hei tirotiro mā te heke mai, inā koa i roto i ngā ahumahi kua whakahaeretia e hiahiatia ana ngā pūkete mō ngā tau maha.
