Whakatupato mo te whakamahi hua
1.Ko te pāmahana i waenga i nga weld e tūtohu ana kia whakahaeretia i te 150°C.A, no te maha-paahi maha-paparanga fehokotaki'anga o te iti me te reo-rahi, whakarongo ki te whakahaere i te pūngao raina fehokotaki'anga.
2.Ko te paparanga waikura, te makuku, te hinu, te puehu, me era atu mea o te wahanga wea me horoi.
3.Me tunu te rere ki te 300-350 ℃ mo te 2 haora i mua i te whakamahi.
Ko nga whakaaro i runga ake nei mo te tohutoro anake, a ko te tino ahuatanga ka kaha i roto i nga mahi motuhake.Mena e tika ana, me whakahaere tohu tohu i mua i te whakatau i te mahere whakaahuru.
