High-auau fehokotaki'anga ko te whakamahi o te pānga kiri ki te hanga i te kaha-auau nui o nāianei kukū i runga i te mata o te mea mahi;Ka whakamahia te awe tata ki te whakahaere i te tuunga me te awhe o te ara rere o naianei.He tino tere te tere o te naianei, ka taea e ia te whakamahana i te taha o te pereti rino tata i roto i te wa poto rawa, ka rewa, ka mohio ki te tauranga na roto i te extrusion kei a ia ano nga painga, engari kei a ia ano nga ngoikoretanga.Ko te tikanga he mea tika ki te wetewete i nga whiringa motuhake i runga i nga ahuatanga motuhake.
Ko te tukanga o te hanga Pipe Whakaaetanga Hiko (ERW) e whai ake nei:
Tuwhera te tirotiro pereti → Whakatika i te mira → tapahi hanga → Te tapahi wea o te reke → Tirotiro tirohanga → Tirotiro irahiko → Tirohanga X-ray → Te whakamatautau pehanga → Chamfering papatahi → Tirohanga whakamutunga
Pupa kore he paninga Pango / Varnish ranei (kua whakaritea);
i roto i te paihere, i te wewete ranei;
Ko nga pito e rua me nga kaitiaki mutunga;
Ko te pito maata, ko te mutunga o te taiawhio(2" me runga ake me nga pito o te bevel, tohu: 30~35°), miro me te hono;
Te tohu.
