Te tukanga hanga o te waea kowiri tira: mai i te rauemi mata ki te hua oti

He rauemi maha ngā whakamahinga o te waea kowiri tira, e whakamahia whānuitia ana i roto i ngā momo ahumahi nā tōna pakari, tōna ātete ki te waikura, me tōna kaha kume. He mea nui te mārama ki te tukanga hanga o te waea kowiri tira mai i te wāhanga rauemi mata ki te hanga hua kua oti. Ka hoatu e tēnei tuhinga he whakataki hōhonu ki te tikanga hanga o te waea kowiri tira me te hangarau tukatuka e uru ana ki te tukanga hanga.

Ka tīmata te haerenga hanga o te waea kowiri tira mā te whiriwhiri i ngā rauemi mata. Ko te wāhanga matua o te waea kowiri tira ko te chromium, e whakanui ana i te ātete ki te waikura o te hua whakamutunga. Hei tāpiri, ka tāpirihia ētahi atu huānga pērā i te nikara, te waro me te manganese hei whakarei ake i ngā āhuatanga motuhake o te waea, pērā i te kaha me te ngāwari ki te hanga. Ka inehia me te whakaranua ēnei rauemi mata ki ngā ōwehenga tika kia tutuki ai ngā āhuatanga e hiahiatia ana.

Kia oti te whakaranu i ngā rauemi mata, ka rewa. Ka whakamahanahia te ranunga i roto i te taiao e tino whakahaerehia ana, i roto i te oumu hiko. I te pikinga o te pāmahana, ka rewa te rauemi mata, ka hanga he koranu wai kowiri tira. Kātahi ka ringihia te kowiri tira rewa ki roto i ngā pokepoke hei hanga i ngā hua haurua-oti pērā i ngā pireti, i ngā ingota rānei.

Ko te taahiraa e whai ake nei i roto i te tukanga hanga ko te hurihuri wera o te hua haurua-oti. Ka whakamahanahia he poro, he poro rānei, ka tukuna mā roto i tētahi raupapa roera, ka whakaiti haere i tōna matotoru. Ka āwhina te tukanga hurihuri wera ki te whakapai ake i te hanganga o te kopa o te maitai kore waikura me te whakapai ake i ōna āhuatanga hangarau. He mea nui te whakaiti matotoru e tutukihia ana i te wā hurihuri wera kia whiwhi ai i te diameter waea maitai kore waikura e hiahiatia ana.

I muri i te hurihanga wera, ka uru te maitai kore waikura ki tētahi tukanga e kiia nei ko te whakamahana. Ko te whakamahana he whakamahana i te waea maitai kore waikura ki tētahi pāmahana kua whakaritea, ā, ka pupuri i taua mea mō tētahi wā kua whakaritea. Mā tēnei tukanga ka whakamama i te ahotea o roto, ka whakangawari i te rauemi, ka ngāwari ake te hanga. Ka whakatikatikahia hoki e te whakamahana te hanganga tioata, ā, ka whakapai ake i te ngāwari o te miihini me te hanga o te waea.

I muri i te whakamahana, kua rite te waea kowiri tira mō te kukume makariri. Ko te kukume makariri ko te kukume i te waea mā roto i tētahi raupapa o ngā mate hei whakaiti haere i tōna whānui me te whakanui ake i tōna roa. Ka whakapai ake hoki te tukanga i te āhua o te mata o te waea, ka whakakore i ngā ahotea o roto e toe ana, ā, ka whakapai ake anō i ōna āhuatanga hangarau. Ka taea te kukume i te waea kowiri tira i ngā wā maha hei whakatutuki i te whānui e hiahiatia ana, kia mau ai te ōritetanga me te kounga.

Ko te taahiraa whakamutunga o te tukanga hanga ko te maimoatanga mata. He maha ngā wā ka hiahiatia he maimoatanga mata mō te waea kowiri tira pēnei i te whakapūkara, te whakakorenga, te paninga rānei, i runga i te whakamahinga e tika ana. Ko te whakakorenga he tango i te unahi, i ngā poke rānei mai i te mata o te waea, ko te whakakorenga ka hanga he paparanga waikura angiangi e whakarei ake ana i te ātete ki te waikura. Ka taea hoki te whakamahi i ngā tukanga paninga pēnei i te whakakikorua hiko, te whakapūkara rānei hei whakarato tiaki tāpiri, hei whakapai ake rānei i te āhua o te waea.
