Te Whakarewa Kowiri tiraIrahiko
A902
GB/T E320-16
AWS A5.4 E320-16
Whakaahuatanga: He hiko kowiri tira te A902, he paninga titanium-konupūmā. Ka taea te whakamahi mō te AC me te DC, ā, he tino pai te mahi. He tino ātete ki te waikura me te kaha ki te waikura te konganuku kua whakatakotoria, ā, he whānuitia te whakamahinga i roto i te hanga i ngā ahumahi matū, te hinu, me ngā taputapu hanga hauwai.
Whakamahinga: Whakamahia mō te whakarewa i te koranu nikara Carpenter20Cb i roto i te waikawa whanariki, te waikawa hauota, te waikawa phosphoric me te waikawa waikura. Ka taea hoki te whakamahi mō te whakarewa maitai rerekē.
Te hanganga matū o te konganuku whakarewa (%):
| C | Si | Mn | Cr | Ni | Mo | Cu | Nb | S | P |
| ≤0.07 | ≤0.60 | 0.5 ~ 2.5 | 19.0 ~ 21.0 | 32.0 ~ 36.0 | 2.0 ~ 3.0 | 3.0 ~ 4.0 | 8 XC ~ 1.00 | ≤0.030 | ≤0.030 |
Ngā āhuatanga hangarau o te konganuku whakarewa:
| tūemi whakamātautau | Te kaha o te kume Mpa | Te whakaroa % |
| Kua whakamanahia | ≥550 | ≥30 |
Iahiko e taunakitia ana:
| Te whānui o te tokotoko （mm） | 2.5 | 3.2 | 4.0 |
| Iahiko Whakarewa （A） | 50 ~ 80 | 80 ~ 110 | 110 ~ 160 |
Pānui:
- Me tunu te hiko mō te 1 hāora i te pāmahana tata ki te 150℃ i mua i te mahi whakarewa;
- Nā te mea he papaku te hohonutanga o te urunga i te wā e whakarewahia ana te hiko AC, me whakamahi te pūtake hiko DC kia hohonu ake te urunga, ā, kaua hoki te iahiko e nui rawa kia kore ai e whero te tokotoko whakarewa.
I whakatūria a Wenzhou Tianyu Electronic Co., Ltd. i te tau 2000. Kua uru mātou ki te hanga ohiko whakarewas, ngā tokotoko whakarewa, mengā mea whakapau mō te whakarewamō ngā tau neke atu i te 20.
Ko ā mātou hua matua ko ngā irahiko whakarewa kowiri tira, ngā irahiko whakarewa maitai waro, ngā irahiko whakarewa koranu iti, ngā irahiko whakarewa mata, ngā irahiko whakarewa koranu nikara me te kobalta, ngā waea whakarewa maitai ngawari me te koranu iti, ngā waea whakarewa koranu kore waikura, ngā waea whakaheke hau-ārai, ngā waea whakarewa konumohe, ngā waea whakarewa pewa ruku. ngā waea, ngā waea whakarewa koranu nikara me te kobalta, ngā waea whakarewa parahi, ngā waea whakarewa TIG me te MIG, ngā irahiko tungsten, ngā irahiko keri waro, me ētahi atu taputapu whakarewa me ngā taonga pau.
