ER385 Rakau Whakarewa Kowiri tira
Whakaahuatanga Poto:
He momo whakarewa whakakī te ER385, he hiko kowiri tira rānei. Ko te "ER" he tohu mō te "Hiko, te Rākau rānei," ā, ko te "385" e tohu ana i te hanganga matū me ngā āhuatanga o te whakarewa whakakī. I tēnei wā, kua hangaia te ER385 mō te whakarewa i ngā maitai kowiri tira austenitic.
ER385 Rakau Whakarewa:
Ko ngā maitai kore waikura austenitic, pērā i te Momo 904L, he nui ngā taumata o te chromium, te nickel, me te molybdenum, ā, he tino ātete ki te waikura, he pai hoki mō te whakamahi i roto i ngā taiao uaua. E whakamahia whānuitia ana ngā tokotoko whakarewa ER385 i roto i ngā tono e tino nui ana te ātete ki te waikura, pērā i roto i ngā ahumahi matū, hinu, me te moana. He pai ngā tokotoko whakarewa ER385 mō ngā momo tukanga whakarewa, tae atu ki te whakarewa pewa whakarewa ārai (SMAW), te whakarewa pewa tungsten hau (GTAW, TIG rānei), me te whakarewa pewa whakarewa hau (GMAW, MIG rānei).

He aha ngā āhuatanga o te Waea Whakarewa ER385?
1. He ātete pai ki te waikura, ka taea te ātete i te waikura ōrite o te waikawa whanariki me te waikawa phosphoric, te ātete i te waikura o te waikawa acetic i tetahi pāmahana me te kukū i raro i te pēhanga noa, ā, ka taea te whakaoti rapanga pai i te waikura poka, te waikura poka, te waikura kapiti, te waikura ahotea me ētahi atu raruraru o ngā halide.
2. He ngawari, he pumau te pewa, he iti ake te tauhiuhi, he ataahua te āhua, he pai te tango paru, he pumau te whāngai waea, ā, he tino pai te mahi tukanga whakarewa.
Ngā tūranga whakarewa me ngā mea nui:
1. Whakamahia ngā ārai ātete hau i te wā e whakarewa ana i ngā wāhi hau nui hei karo i ngā pūnga pupuhi i puta mai i ngā hau kaha.
2. Ka whakahaerehia te pāmahana i waenga i ngā haerenga ki te 16-100℃.
3. Me tango katoa te makuku, te waikura me ngā paru hinu i runga i te mata o te konganuku turanga i mua i te whakarewanga.
4. Whakamahia te hau CO2 mō te whakarewa, me neke atu i te 99.8% te parakore, ā, me whakahaere te rere o te hau i te 20-25L/min.
5. Me whakahaere te roanga maroke o te waea whakarewa i roto i te awhe o te 15-25mm.
6. I muri i te wetewete i te waea whakarewa, kia mōhio koe: me mahi i ngā mahi ārai makuku, whakamahia wawe tonu, kaua hoki e waiho te waea whakarewa kāore i whakamahia kia noho noa i te rangi mō te wā roa.
