I hangaia tuatahitia te whakarewa TIG i Amerika (USA) i te tau 1936, e mōhiotia ana ko te whakarewa pewa Argon. Mā te TIG ka taea te hanga hononga whakarewa kounga teitei me ngā tautoko hau kore mahi, ā, ka puta he hua whakarewa ma. He tikanga whakarewa whānui tēnei tikanga whakarewa e pā ana ki te rauemi e whakamahia ana, te matotoru o te pakitara, me ngā tūranga whakarewa.
Ko ngā painga o tēnei tikanga whakarewa ko te iti o te tauhiuhi me te iti o ngā poke, ā, ka oati hoki he hononga whakarewa kounga teitei mēnā ka whakamahia tika. Kāore e honoa te whāngai o ngā mea whakarewa me te iahiko, nō reira he pai te TIG mō te whakarewa i ngā ara pakiaka me te whakarewa tūnga.
Heoi, me whai kaiwhakarewa TIG he tohunga whakarewa, ā, me mōhio hoki ki te whakamahi tika i te ngaohiko me te amperage. Mā ēnei ka puta he hua pai, he ma hoki. Ā, ki taku whakaaro koinei ngā āhuatanga ngoikore o te whakarewa TIG.
E kitea ana i roto i taua pikitia, i muri i te pēhi i te pana o te rama ka tīmata te rere o te hau. Ā, ina pā te pito o te rama ki te mata o te konganuku, ka puta he ara iahiko poto. Nā te nui o te iahiko i te pito o te rama, ka tīmata te mimiti o te konganuku i te wāhi e pā ana, ā, ka mura te pewa, me te mea kua kapi i te hau tiaki.
TE WHAKATAU I NGĀ PĒHANGA/RERE HAUREHU
Ko te tere rere o te hau kei roto i te l/min, ā, e whakawhirinaki ana ki te rahi o te puna whakarewa, te diameter o te irahiko, te diameter o te pūwero hau, te tawhiti o te pūwero ki te mata whakarewa, te rere o te hau e karapoti ana me te momo hau tiaki.
Ko tētahi ture māmā ko te tāpiri i te 5 ki te 10 rita o te hau tiaki ki te hau argon hei hau tiaki, me ngā diameter o te irahiko tungsten e whakamahia whānuitia ana, i te tere o te 1 ki te 4 mm ia meneti.
TŪRANGA RAMA
Pērā i te whakarewa MIG, he mea tino nui anō hoki te tūranga o te rama, ina whakamahia te tikanga whakarewa TIG. Ka pā te tūranga o te rama me te tokotoko hiko ki ngā hua whakarewa rerekē.
Ko te Irahiko anō hoki he mea whakamahi mō te whakarewa e whakamahia ana i te wā e whakarewa TIG ana. Ko ngā mea whakamahi mō te whakarewa ka tīpakohia i te nuinga o te wā i te huarahi kotahi me te momo konganuku. Heoi, mō ngā take whakarewa, me rerekē ngā mea whakamahi mō te whakarewa mai i te konganuku matua ina whakamahia ētahi huānga whakarewa.
Hoki atu ki te tūranga o te rama. Ka taea e koe te whakamahi i ngā tūranga rerekē o te rama TIG me te tokotoko hikohiko i a koe e whakarewa ana i ngā hononga whakarewa. Nō reira, ko te tūranga o te rama e whakawhirinaki ana ki te momo hononga whakarewa. Arā, e whā ngā hononga whakarewa taketake pēnei i:
Hononga-T
Hononga Kokonga
Hononga o te Papa
Hononga Pona
Ka taea e koe te whakamahi i ētahi o ēnei tūranga rama ki ngā mahi e hiahia ana koe ki te whakaoti. Ā, ina mōhio koe ki ngā momo tūranga rama whakarewa, ka taea e koe te ako mō ngā tawhā whakarewa.
NGĀ TAWHITO WHAKAPĀ
I te wā e whiriwhiri ana i ngā tawhā whakarewa, me mārama ko te iahiko anake ka whakatakotoria ki te mīhini whakarewa. Ka whakatauhia te ngaohiko e te roa o te pewa, e puritia ana e te kai whakarewa.
Nō reira, me nui ake te ngaohiko o te pewa ina roa ake te pewa. Ka whakamahia he ia whakarewa o te 45 amperahe ia mm o te matotoru o te konganuku hei uara tohutoro mō te ia e ranea ana hei whakarewa i te maitai kia uru katoa.
