Me pēhea te whakarewa i te matua ki te maitai kore waikura

He rauemi tino nui te maitai kore waikura i roto i ngā ahumahi pēnei i tete hanga, te tukatuka kai, te matū, te motuka, me te miihini moana. Nā tōna pakari, tōna ātete ki te waikura, me tōna āhua ma, he mea tino whai hua. Heoi, he uaua ake te whakarewa i te maitai kore waikura i te maitai waro nā te meate whānui o te wera, te whakapakeketanga mahi, me te ngāwari ki te whakapohehe.

Ko tētahi tikanga whai hua hei hono i te kowiri tira kowhakarewa pewa matua rere (FCAW). Ka whakamahia e tēnei tukanga he hiko pau e whāngaihia tonutia ana kei roto te rere i tōna pūtake, e whakaputa ana i te hau tiaki me te para hei tiaki i te whakarewa mai i te poke. I roto i tēnei tuhinga, ka whakaratohia e mātou he aratohu whānui mōme pēhea te whakarewa i te matua ki te kowiri tira, tae atu ki ngā taputapu tika, ngā waea whakakī, ngā tikanga, me ngā mahi pai rawa atu.

Te Mārama ki te Whakarewa Matua Rere (FCAW)

He tukanga whakarewa ā-aunoa, ā-aunoa rānei te whakarewa matua rere. He rite ki te whakarewa MIG engari he rerekē te āhua o te ārai i te whakarewa.

Ngā momo whakarewa matua rere:

1. Parenga-ā-Whaiaro (FCAW-S):

   • Ka whakamahi i te rerenga i roto i te waea hei whakaputa hau tiaki.

   • He pai mō ngā mahi o waho me ngā taiao hau nui.

2. Parenga-Hau (FCAW-G):

   • Me hiahia he hau tiaki o waho tāpiri (pēnei i te CO₂, te ranunga Ar/CO₂ rānei).

   • Ka whakaputa i ngā whakarewanga ma ake me te iti ake o te tauhiuhi.

Mō te whakarewa maitai kore waikura,ngā waea matua rere e tiakina ana e te haue pai ake ana te nuinga nā te mea he pai ake te kounga o te whakarewa.

He aha i whakamahia ai te Flux Core mō te Kowiri tira?

• Te Reiti Whakatakotoranga Teitei:Ka tere ake te whakarewa i te TIG, i te rākau rānei.

• He pai mō ngā rauemi matotoru:He tino pai te uru mō ngā wāhanga taumaha.

• Ngā mahi maha:Ka taea te whakamahi i ngā tūranga papatahi, poutū, me runga ake hoki.

• Whai hua te utu:He iti ake te utu o ngā taputapu ki te whakataurite ki te whakarewa TIG.

• Te Whaihua mō Waho:Ka mahi te FCAW ārai-ā-unoa i ngā taiao e kore ai e rahua te whakarewa MIG nā te hau.

Ngā Taputapu e Hiahiatia ana

1. Mīhini Whakarewa

   • He pūhiko hiko ngaohiko pumau (he mīhini whakarewa MIG hototahi ki te matua rere).

   • Me whakamahi i ngā diameter waea kowiri tira (ko te nuinga he 0.9 mm, 1.2 mm rānei).

2. Waea Kowiri tira matua rere

   • Ko ngā māka te tikanga kei rotoNgā waea 308L, 309L, me te 316L he pūtake-rerenga, i runga i te konganuku turanga.

3. Hau Whakamarumaru (mō FCAW-G)

   • Ākoni + CO₂ (ranunga 75/25) CO₂ tika rānei.

4. Taputapu Tiaki

   • He potae whakarewa, he karapu, he koti, me ngā mōhiti haumaru.

5. Ngā Utauta Whakarite

   • Mīhini huri hei horoi i te konganuku turanga.

   • Paraihe waea (paraihe kowiri tira hei ārai i te poke).

Aratohu Hipanga-i-te-Hipanga: Me pēhea te Whakarewa i te Matua ki te Kowiri tira

Hipanga 1: Whakaritea te Mea Turanga

• Horoia rawatia te kowiri tira.

• Tangohia te paru, te hinu, te peita, me ngā paparanga waikura.

• Whakamahia he paraihe kowiri tira hei karo i te poke o te waro.

Hipanga 2: Kōwhiria te Waea Matua Rere Tika

• Tātaitia te momo waea whakakī ki te momo maitai kore waikura:

  • Waea 308L:Mō te whakarewa maitai kore waikura 304

  • Waea 309L:Mō te hono i te kowiri tira ki te maitai ngawari

  • Waea 316L:Mō ngā tono kowiri tira 316 me te moana

Hipanga 3: Kōwhiria ngā Tautuhinga Whakarewa

• Ko te ngaohiko me te amperage e whakawhirinaki ana ki te rahi o te waea me te matotoru o te rauemi.

• Tauira: Mō te maitai kore waikura 1/8 inihi me te waea 0.9 mm → 18–20 volts, 150–180 amps.

Hipanga 4: Whakamahia te Hau Parepare Tika (mēnā he FCAW-G)

• Ranunga pai:75% Ākona / 25% CO₂mō ngā whakarewa maeneene ake, me te iti ake o te tauhiuhi.

• Ka taea te whakamahi i te CO₂ tika engari ka puta he mata taratara.

Hipanga 5: Te Tūnga me te Whakapiripiri Tack

• Whakauhia ngā wāhanga mahi mā te whakamahi i ngā rawhi.

• Whakamahia ngā whakapiripiri tack hei ārai i te whakapohehe.

Hipanga 6: Tikanga Whakarewa

• Kia mau tonukoki tōia (10–15°)ina whakamahia te matua rere ārai-whaiaro.

• Kia mau tonu te tere haere kia kore ai e wera rawa.

• Mō te whakarewa poutū, whakamahia te haere whakamua ki runga kia pai ake ai te werohanga.

Hipanga 7: Tango Para

• I muri i te whakarewanga, tukua te hononga kia whakamatao.

• Whakamahia he hama tapatapahi me te paraihe waea hei tango i ngā putunga paru.

Hipanga 8: Te Horoi i Muri i te Whakarewa

• Me horoi te kowiri tira i muri i te whakarewanga hei ārai i te poke.

• Whakamahia he paraihe kowiri tira, he maimoatanga whakakorekore rānei mēnā e tika ana.

Ngā Tikanga Pai rawa atu

• Kia iti te whakaurunga wera:Ka whakapōturitia te āhua o te waikura e te wera nui rawa, ā, ka ngaro te ātete ki te waikura.

• Whakahaere i te Pāmahana o te Waenga:Kaua e neke ake i te 150°C mō te nuinga o ngā maitai kore waikura.

• Ārai i te Whakawhitiwhitinga o te Parahanga:Kaua e whakamahia ngā taputapu maitai waro ki runga i te maitai kore waikura.

• Whakaharatau i te Whakahaere Pīra:Whakamahia ngā pīrere aho hei utu mō ngā raranga whānui kia pai ake ai te uru.

• Tirohia ngā hononga:Tirohia mēnā he pūngao, he kapiti, me ngā whakaurunga paru.

Ngā Hapa Noa hei Ārai

• Te whakamahi i te momo waea matua rere hē (ka pā te ngatata me te waikura).

• Te whakarewa me te kore he hau tiaki tika ina hiahiatia.

• Te wera rawa o te maitai kore waikura, ka piko ai.

• Te kore aro ki te horoinga i muri i te whakarewanga, ka whakaitihia te ātete ki te waikura.

• Kāore i te rawaka te whakarite hononga, ka ngoikore ai ngā whakarewanga.
