Ngā Pūrongo Hua

I roto i te umanga hanga waka e piki haere ana te whakataetae, ko te hauora me te mahi a ngā pokepokea ai te mea e whakatau tika ana i te kounga o ngā wāhanga kua tāia, te whai huatanga o ngā raina whakaputa, me te kounga whakamutunga o ngā waka. I a koe e anga atu ana ki te kati me te tango i ngā pokepokea ai nā te kakahu, te karawarawa, me te waikura, kei te pāngia koe e ēnei āhuatanga mamae?

I te 7:30 i te ata, i taraiwa tā mātou tīma hangarau i roto i te raima haukū o te wheketere, ā, i tū ki mua i te awheawhe mīhini taumaha a te kiritaki. I tēnei rā, i mahi mātou i te whakakikorua laser ki te pakitara o roto o te kōhao titi mō tētahi wāhanga nui o te taputapu—te anga aorangi.

Nō nā tata nei, kua wehe atu tētahi puranga taputapu tinei laser tino tika i whakawhanakehia i roto i te mahi tahi me tā mātou kamupene ki Vietnam. He tohu tēnei i tētahi whanaketanga nui i roto i te aroaro o tā mātou kamupene ki te mākete o te Tonga-Rawhiti o Āhia, e tohu ana kua piki ake te rongonui o tā mātou hangarau maimoatanga mata laser matatau ki te ao. Ka werohia e ngā taputapu he nekehanga hangarau hou ki roto i te rāngai hanga ahumahi o Vietnam.

I roto i ngā mahi ahumahi o ēnei rā, ko ngā taputapu roera pēnei i ngā roera hurihuri, ngā roera kawe, me ngā rango whakamaroke hei pou tuarā mō ngā raina whakaputa. Ka tū pakari ēnei wāhanga ki te pēhanga nui, te waku kaha, te pāmahana teitei, me ngā taiao waikura. Ko te kounga o te mata o ēnei wāhanga e whakatau tika ana i te pai o te whakaputa, te kounga o te hua, me te roa o te mahi.

I roto i te ao o te miihini keri, ko ngā āhuatanga mahi tino uaua tonu te wero matua e whakararu ana i te mahi pumau o ngā taputapu. He kuiti, he whaiti hoki ngā taiao keri whenua, ā, ko te puehu kukū nui e memeha haere ana i ngā mata o ngā taputapu.

Ngā rauemi whakarewa ferrous (te mea tino rongonui i tēnei wā)
1. He maitai waro-waenga me te waro-teitei (te ihirangi waro 0.3%~0.8%), ko ngā rauemi noa: 45 maitai (te maitai hanganga waro-waenga kounga teitei), kua tohua ko S45C i roto i ngā paerewa JIS, ASTM 1045/080M46, me te DIN C45, he maitai hanganga waro kounga teitei me te hanganga matū e whai ake nei:

I te tere o te whanaketanga o te umanga motuka me te haere tonu o ngā whanaketanga o ngā kaha hanga, kua noho ngā pokepokea ai hei taputapu tukatuka nui i roto i te hanga motuka. Ko tōna kounga me tana mahi ka whakatau tika i te tika, te roa o te ora, me te whai huatanga o te hanga o ngā wāhanga motuka.

He tukanga hou te tinei i te wera i runga i te reera e whakamahi ana i ngā hihi reera kaha-teitei hei whakamahana i ngā mata o ngā rauemi ki tua atu i ō rātou pūwāhi whakawhiti āhua. I te whakamataotanga māori o te rauemi, ka huri te austenite hei martensite, ka hangaia he paparanga mārō me te tino pakari me te ātete ki te kakahu i runga i te mata o te hua.

I raro i te hohonutanga o ngā maina waro, ka wiriwiri ngā pou tautoko waipēhi i roto i ngā pūnaha maina miihini katoa i raro i te pēhanga 10,000-tana, ka huri ngā waka kawe waru ki te konukōre waro, i te mea ka uaua ngā rango waipēhi ki te mahi i roto i ngā taiao makuku me te waikura.
