Ngā irahiko whakarewa nikara me te koranu nikaraHe tino ātete ki te waikura, ā, ka noho pumau tonu i roto i ngā taiao uaua pēnei i te waikawa, te kawakore, me te wai tote. Ka taea e rātou te pupuri i te kaha me te ātete ki te waikura i ngā pāmahana teitei, ā, he pai mō ngā tono wera maha. Ko te pumau o te pewa, te iti o te tauhiuhi, me te tere whakatakotoranga teitei ka maeneene ake, ka whai hua ake hoki te tukanga whakarewa. He tino ātete ngā irahiko whakarewa nikara me te konukōre nikara ki ngā kapiti wera me te makariri, e whakarite ana i te whakarewa roa me te pono. Nā te maha o ngā whakamahinga ka taea te hototahi ki ngā momo konukōre nikara me te nikara, tae atu ki te monel, inconel, me te hastelloy, hei whakatutuki i ngā hiahia rerekē. Kāore e taea te wareware i ngā āhuatanga tiaki taiao. Ko te iti o ngā tukunga paowa me ngā rauemi hoa taiao ka whakarato i tētahi taiao mahi haumaru ake.
He mea hanga ngā irahiko whakarewa nikara me te konukōre nikara ki ngā konukōre nikara me te nikara kounga teitei hei whakarite i te mahi pumau me te roa. He pai mō ngā momo tukanga whakarewa, tae atu ki te SMAW (whakarewa rākau) me ngā tikanga whakarewa GTAW/TIG hei whakatutuki i ngā hiahia whakarewa rerekē. Mā te mahi pewa maeneene ka māmā te whakahaere me te whakahaere tika i te wā whakarewa. He kaha, he roa te whakarewa, ka puta he whakarewa kaha mō ngā tono uaua. Ka taea te whakarerekē i te whānuitanga o ngā diameter irahiko ki ngā mahi whakarewa me ngā taputapu rerekē, kia ngāwari ai te whakamahi. He roa te wā e ora ana, ā, he ātete ki te makuku me te kino ka roa te mahi pumau.
Ko ā mātou irahiko whakarewa nikara me te konukōre nikara te whiringa tuatahi mā ngā tohunga e rapu ana i ngā otinga whakarewa pono, mahi teitei. Ahakoa i roto i ngā taiao waikura, i ngā tono pāmahana teitei, i roto rānei i ngā ahumahi nui pēnei i te rererangi me te mana karihi, ka whakaratohia e ēnei irahiko te kounga me te pakari e kore e taea te whakataurite. Ka whakakotahihia e ngā irahiko whakarewa nikara me te konukōre nikara te ātete ki te waikura, te kaha pāmahana teitei, me te ngāwari o te whakamahi kia tino whiwhi koe i ngā hua pai i ia wā ka whakarewa koe.
Mā ā mātou irahiko whakarewa nikara me te koranu nikara kounga teitei, ka taea e koe te whakapai ake i te kounga o ō kaupapa whakarewa. I hangaia ki ngā paerewa kounga me te mahi tino teitei, he pai ēnei irahiko mō te whānuitanga o ngā tono mai i te tukatuka matū ki te hangarau rererangi. Ka whakaratohia e ngā irahiko whakarewa nikara me te koranu nikara he otinga pono, pakari me te kounga teitei mō ngā mahi whakarewa tino uaua.
