1, Te whakarewatanga o te pewa hikohiko
Ko te whakarewa pewa tētahi o ngā pūkenga taketake e matatauhia ana e ngā kaiwhakarewa; ki te kore ēnei pūkenga e tika ana, ka puta he maha ngā hapa i roto i te hononga whakarewa.
2, Whakarewa pewa rukuhia
Ko te whakarewa pewa ruku he tikanga whakarewa e whakamahi ana i te pewa hei pūtake wera. Nā te hohonu o te urunga o te whakarewa pewa ruku, he pai te kounga o te whakarewa: nā te tiakitanga o te para rewa, kāore te konganuku rewa e pā ki te hau, ā, he teitei te taumata o te mahi mīhini, nō reira he pai mō te whakarewa i ngā whakarewa roa o ngā hanganga pereti reo me te matotoru.
3. Te whakarewatanga o te pewa o te ākono
Anei ētahi whakatūpato mō te whakarewanga pewa argon:
(1) Me whakakoi pinepine te ngira tungsten. Ki te mea he pūngoi, kāore e kukū te iahiko, ā, ka mutu te whakarewanga.
(2) Ki te tata rawa te tawhiti i waenganui i te ngira tungsten me te whakarewa, ka piri tahi rāua. Ki te tawhiti rawa, ka puāwai te pewa. Kia puāwai te pewa, ka mangu te mura, ā, ka pakira te ngira tungsten. He kaha hoki te irahiko ki te tangata. He pai ake te pupuri tata.
(3) He mahi toi te whakahaere i te pana, inā koa mō te whakarewa pereti angiangi. Ka taea anake te tahuri takitahi. Ehara tēnei i te mīhini whakarewa aunoa me te nekehanga aunoa me te whāngai waea aunoa. Ki te mura tonu, ka tawhito.
(4) Me whāngai koe i te waea. Me pā te pā ki tēnei. Ka tapahia te waea whakarewa kounga teitei mai i ngā pereti 304 mā te mīhini kutikuti. Kaua e hoko i roto i ngā paihere. Ae ra, ka kitea e koe ngā mea pai i ngā toa hokomaha.
(5) Ngāna ki te mahi i roto i ngā āhuatanga hauhautanga, mau karapu hiako, kākahu, me te kopare whakamaroke aunoa.
(6) Me ārai te pane uku o te pū whakarewa i te pewa. Ina koa, me anga te hiku o te pū whakarewa ki tō mata i te mea ka taea.
(7) Ki te mea ka taea e koe te whai whakaaro ā-roto me te matapae mō te pāmahana, te rahi, me te mahi o te puna rewa, he tohunga hangarau matua koe.
(8) Whakamātauria te whakamahi i ngā ngira tungsten he kōwhai, he mā rānei ngā tohu, nā te mea he nui te mahi toi e hiahiatia ana mō tēnei.
4. Te whakarewanga wahie hāora
Ko te whakarewa hau wahie hāora ko te whakamahinga o te mura hei whakamahana i te konganuku me te waea whakarewa i te hononga o ngā wahi mahi konganuku hei whakarewa i a rātou, hei whakatutuki i te kaupapa o te whakarewa. Ko ngā hau mura e whakamahia whānuitia ana ko te acetylene, te hau hinu wai me te hauwai, ā, ko te hau tautoko mura e whakamahia whānuitia ana ko te hāora.
5. Te whakarewatanga taiaho
He tikanga whakarewa whai hua, tika hoki te whakarewa reera, e whakamahi ana i te hihi reera kiato-pūngao teitei hei pūtake wera. Ko te whakarewa reera tētahi o ngā āhuatanga nui o te whakamahinga o te hangarau tukatuka rauemi reera. I ngā tau 1970, i whakamahia nuitia mō te whakarewa i ngā rauemi angiangi me te whakarewa tere-iti. He momo kawe wera te tukanga whakarewa, arā, ka whakamahanahia e te hihi reera te mata o te mea mahi, ā, ka horapa te wera o te mata ki roto mā te kawe wera. Mā te whakahaere i te whānui, te pūngao, te mana tihi me te auau auau o te pā o te reera, ka rewa te mea mahi hei hanga i tētahi puna rewa motuhake.
