Ka whakamahia te hau awhina i te wa e tapahi ana i te rino/whakarewa rereke.
Ko te hau awhina te mea e tika ana ina tapahi konganuku/ maitai.Engari he aha te rerekee o te konganuku / maitai e hiahia ana kia rereke te hau awhina?Na te mea he rereke nga whakarewa / rino he rereke nga waahanga tinana.
Ka tapahia e te miihini laser muka te kowiri tira, ka whakamahia te Nitrogen.Ka tapahia e te miihini taiaho muka te maitai waro, ka whakamahia te Oxygen.
A, no te ki te kowiri tira, he iti te waro ihirangi, haunga reira he onge ihirangi pērā i chrome, nickel, molybdenum.He nui te hauota hei hau awhina ina tapahi.
A, no te ki te waro maitai, waro ihirangi he nui ake, he mea tika ki te hāora ki te hoatu i te mana ngingiha-tautoko ki te whakatutuki i pai hua tapahi.
Na te kino o te mahi tapahi me te moumou i o rawa ina whakamahi hau he, uru ranei enei hau e rua.Tena koa whakarongo mai!
