JQ.H0Cr21Ni10 he kowiri tira hau-maara waea totoka
Kupu Whakataki
Ko te waahanga matua o JQ.H0Cr21Ni10 ko 18Cr-8Ni, ko te TIG te waea whakapiri mo te kowiri tira.Karekau he mokamoka, he maeneene te whakapiri.He pai hoki te waea pai ki te weld ki muri i te mea kaore e taea te uru atu i te wa e taea ai e te recoting te whakatutuki i te pirepire ataahua ki mua.

Notes
1. Hau parepare: Me whakarite kia kaua e mahi me te hau parepare poke.
Reiti Tohutohu o te hau hanumi: Ar+1-3%O2.
2. Te rere rere o te hau maru: 20-25L / min.
3.toronga hiko: 15-25mm
4.Me whakahaere te whakapiri ki te mata ma kaore he waikura, he makuku, he poke hinu me te puehu.
5.Aukati i te pa o te hau ina eke te tere o te hau ki te 1.5m/s hei karo i nga mirumiru.
Ko nga whakaaro o runga ake nei hei tohutoro.Aromātai me te whakatau i te ahuatanga o te waahi i mua i te tiimata i te mahi whakahaere.
