Whakaahuatanga
He waea totoka maitai kore waikura martensitic te ER410NiMo, he 11.0 – 12.5% Cr, 4.0 – 5.0% Ni, me te 0.40 – 0.70% Mo te hanganga matū. He pai mō te whakarewanga hau (pērā i te TIG/MIG) i ngā tūranga katoa. I te wā whakarewanga, he pumau te pewa, ā, he pai te ātete o te konganuku kua whakatakotoria ki te cavitation, te ātete ki te kakahu onepu,
me ngā āhuatanga ā-ringa. Kāore e hiahiatia te whakamahana i mua i te whakarewa; e taunakihia ana te maimoatanga wera i muri i te whakarewa (PWHT) i te 580~620℃ mō ngā hāora e 2 (ā, muri iho ka whakamataohia te hau, AC) e ai ki ngā whakaritenga tono. Ka taea te miihini i te konganuku kua whakatakotoria, ā, he pai mō ngā taputapu pēhanga.
Tono
I hangaia mō te whakarewa maitai whakarewa ASTM CA6NM, te maitai kore waikura 410/410S/405, me ngā maitai raupapa 13%Cr – 4%Ni rite tonu. Ko ngā whakamahinga noa ko ngā taputapu pēhanga (e rite ana ki ngā paerewa oko pēhanga), ngā mata tāpine, ngā takirere, ngā paipa pēhanga teitei, me ngā wāhanga hanganga e hiahia ana kia ātete ki te waikura me te kakahu.

Tawhā Whakarewa i Manakohia
Hau Whakamarumaru: Ākona (Ar) Ar rānei+1-2% O2 (mō te whakarewa TIG/MIG, whakarerekētia kia rite ki ngā tukanga motuhake).
Pānui
1. Me whakarite kia ma te mata o te waea, kia kore he hinu, he waikura, he makuku rānei i mua i te whakamahinga kia kore ai e pā ki te kounga o te whakarewa.
2. Kia mau tonu te parakore o te hau me te tere rere tika hei ārai i te porosity me te ngatata i puta mai i te hauwai.
