Kāore he mea e whakarihariha ake ana i te patu i tētahi pewa ki tō rākau whakarewa, ā, ka tūtaki noa ki te tauhiuhi, te porosity, te whakarewa ngoikore rānei e kore e mau. Ahakoa kei te whakatika koe i ngā taputapu pāmu i te mara, kei te hanga rānei i ngā hanganga maitai i roto i te toa, he mahi uaua te whakarewa rākau whakarewa—engari he ngāwari ki te pāngia e ngā raruraru noa e pā ana ki ngā tohunga mohio. Ka tapahia e tēnei aratohu ngā kupu matua hei whakatika wawe i ngā raruraru whakarewa rākau whakarewa tino whakarihariha, kia taea ai e koe te hoki ki te hanga whakarewa kaha, ma i ngā wā katoa.
Ngā Mea Me Mōhio Koe Mō Ngā Kaupapa Taketake me Ngā Āhuatanga o te Rākau Whakarewa
Ko te rākau whakarewa, te poutokomanawa o te whakarewa ā-ringa mō ngā tekau tau, e whakawhirinaki ana ki tētahi hiko pau kua pania ki te rere hei hanga i tētahi pewa, hei whakarewa i te konganuku, hei hanga hoki i tētahi whakarewa. Kāore i rite ki te whakarewa MIG, TIG rānei, he mea kawe, he ātete ki te hau, ā, ka mahi ki ngā rauemi paru, matotoru rānei—he mea nui mō te hanga, te whakatika paipa, te tiaki mīhini taumaha, me ngā mahi o waho. He mea nui te paninga rere: ka tahuna hei tuku i te hau tiaki me te hanga para, hei tiaki i te puna whakarewa mai i ngā poke. Engari koinei te raruraru—ko ngā hapa iti i roto i te rokiroki, ngā tautuhinga tawhā, ngā tikanga rānei ka raru pea i tāu mahi. Me ruku tātou ki ngā whakatikatika mō ngā take ka pāngia koe e te nuinga o te wā.
Ngā Take Matua o te Rākau Whakarewa me te Me pēhea te Whakatika
1. Te Pūngao
Ko te pūngao te hoariri o te whakarewa kaha—ko aua kōhao iti, rite ki te mirumiru ka ngoikore te hononga, ka poke hoki te tohu. Ko ngā take matua? Ko te makuku, te paru o te konganuku turanga, te roa hē rānei o te pewa.
Ngā otinga:Rokirokihia ngā rākau whakarewa ki te wāhi maroke me te haumākū kei raro i te 60%, ā, rongoatia i mua i te whakamahinga—me 150-250°C te pāmahana mō ngā hiko waikawa, ko ngā hiko taketake ia me 350-400°C. Horoia te konganuku turanga ki te huri hei tango i te waikura, te hinu, te peita rānei. Kia poto te pewa kia kore ai te hau e uru ki roto i te puna whakarewa. Ki te mea kei waho koe e whakarewa ana, tiakina te wāhi mai i te hau, e kukume ana i ngā poke ki roto i te wai rewa.
2. Te Piri o te Hikohiko ki te Mea Mahi
E kore rawa ngā tauhou me ngā tohunga e pai ki terākau whakarewaka piri ki te konganuku. I te nuinga o te wā ka puta tēnei i te iti o te iahiko, i te puhoi o te tīmatanga o te pewa, i te pakaru rānei o te hiko.
Ngā otinga:Whakanuia ake te ia whakarewa - tirohia ngā aratohu a te kaihanga hiko mō te rahi o tō rākau whakarewa. Ina pā ki te pewa, whakamahia te tikanga waru, ka hiki wawe i te hiko hei whakatū i te pewa. Ki te piri, whakangaueuetia mārire te hiko, patohia rānei ki te konganuku kia mawhiti - karohia te kukume, ka kino pea te paninga hiko.
3. Te Whakaurunga o te Para (Te Para i Mau i roto i te Whakarewa)
Ko te para te kirinuku e toe ana i muri i te whakarewa, engari ki te mau ki roto i te whakarewa, ka puta he ngoikore. Ka puta tēnei ina kore e horoia te para o mua, he iti rawa te iahiko, herākau whakarewawhānui rawa ngā piu.
Ngā otinga:Tapatapahia ngā para katoa ki te hama me te paraihe waea i waenga i ngā whakawhiti - kaua e pekehia tēnei taahiraa. Whakanuia te ia kia tino uru te paru, kia tere ake ai te tere whakarewa, kia kore ai e tau te para ki roto i te puna whakarewa. Whakawhāitihia tō rākau whakarewa kia kore ai e horapa te para ki tua atu i te rohe rewa.
4. Tapahi i raro (ngā awaawa i ngā taha whakarewa)
Ka waiho e te tapahi raro he awaawa papaku i te taha o te konganuku turanga, ka whakaiti i te kaha o te whakarewa me te hanga i ngā pūwāhi ahotea. Ka puta mai i te nui o te iahiko, i ngā pewa roa, i te koki piri whakarewa hē rānei.
Ngā otinga:Whakaitihia te iahiko, kia poto hoki te pewa. Whakatikatikahia te koki o tō rākau whakarewa ki te 15-30 nekehanga e pā ana ki te konganuku turanga—mā tēnei ka ōrite te tohatoha o te wera. Whakaroahia tō tere haere, ā, whakamahia he whatu whaiti hei whakakī i ngā taha. Ki te mahi i ngā whakarewa poutū, i runga rānei i te tuanui, whakatītahahia te hiko ki runga kia paku te whakahaere i te rewa.
5. Pupuhi Āwhata (Te Haereere Āwhata Kore-Pūmau)
Ka puta te pupuhi o te pewa ina whakapōturitia te pewa e te papa aukume e karapoti ana i te whakarewa, ka puta he rewa kore taurite. He mea noa tēnei mō ngā konganuku turanga aukume, ngā hononga whenua kore taurite rānei.
Ngā otinga:Whakanohoia anō te rawhi whenua kia tata atu ki te wāhi whakarewa hei taurite i te papa aukume. Whakamahia he pewa poto ake hei whakau i te pewa. Ki te whakarewa koe i runga i te maitai aukume, whakamahanahia te rauemi kia paku, whakawhiti rānei ki te ia whakarewa AC, ka whakaiti i te pokanoa aukume.
