Ngā wāhanga mīhini ahuwhenua whānui, te pito o te koko parau, te pito o te parau kaha, ātete ki te kakahu
Rauemi tino ātete ki te kakahu: He mea hanga ki te koranu oneone onge chromium molybdenum boron kounga teitei, ā, kua tukuna ki te tukanga maimoatanga wera motuhake, e rua ngā painga o te pito parau, arā, he pakeke teitei me te pakari teitei. Ki te whakatauritea ki te maitai noa, he pai ake te roa o tōna ātete ki te kakahu i roto i te onepu me te kirikiri me te oneone kua whakakīia, ka whakaiti i te wā kore mahi mō te whakakapinga pinepine o ngā wāhanga.
Hoahoa urunga koi: Kua arotauhia e mātou te koki urunga me te raina piko o te pito parau, kia māmā ai te pakaru ahakoa i runga i te oneone maroke me te oneone pakeke, ka whakaitihia te ātete ki te kukume o te tarakihana me te penapena wahie 5% -10%, kia pai ake ai, kia ohanga ake ai hoki ō mahi.
Te tāutanga whakakapinga tika: me whai pūmau i te rahi o te wheketere taketake mō te whakatuwheratanga o te pokepokea ai, me te tino ōritetanga. Ahakoa he parau whenua, he parau tai whenua rānei, ka taea te tāutanga kore-whakangaro, kāore he keri, ā, ka urutau pai ki ngā parau hurihuri waipēhi kounga teitei mai i Leiken, Beisong, Kuhn, me ngā waitohu maha o te motu.
He wāhanga ngoikore, ātete-paowa te pito parau, e tāutahia ana ki te mata o mua o te tinana parau, ka pā tuatahi ki te oneone i te wā e whakamahia ana. He mea hanga, he mea whakarewa rānei mai i te maitai boron kaha-ātete-paowa, ā, ka tukuna ki te tukanga whakamahana motuhake, ka hua ake he pakeke teitei me te pakari pai. Ka taea e ia te tapahi pai i te oneone pakeke me te oneone kua kikī, te whakaiti i te ātete ki te parau, te tiaki i te pito parau matua me te ringa parau, te whakapai ake i te whai huatanga o te whenua pāmu me te kounga o te oneone, ā, he wāhanga ātete-paowa matua e kore e taea te whakauru ki roto i te mahi ahuwhenua whenua maroke me te keri i te mara raihi.
