Whakaahuatanga: He hiko kowiri tira te A317, he iti te paninga hauwai konutai. Whakamahia te DCEP (hiko au tika). He pai ake tōna ātete ki te waikura, te pakaru, me te waikura i te A302 nā te mea kei roto i te konganuku kua whakatakotoria te molybdenum.
Te Whakamahinga: E whakamahia ana mō te whakarewa i te momo rino kore waikura, te pereti rino hiato me te rino rerekē e ātete ana ki te waikura waikawa whanariki (haukini whanariki).
Te hanganga matū o te konganuku whakarewa (%):
| C | Mn | Si | Cr | Ni | Mo | Cu | S | P |
| ≤0.12 | 0.5 ~ 2.5 | ≤0.90 | 22.0 ~ 25.0 | 12.0 ~ 14.0 | 2.0 ~ 3.0 | ≤0.75 | ≤0.030 | ≤0.040 |
Ngā āhuatanga hangarau o te konganuku whakarewa:
| tūemi whakamātautau | Te kaha o te kume Mpa | Te whakaroa % |
| Kua whakamanahia | ≥550 | ≥25 |
Iahiko e taunakitia ana:
| Te whānui o te tokotoko （mm） | 2.0 | 2.5 | 3.2 | 4.0 | 5.0 |
| Iahiko Whakarewa （A） | 25 ~ 50 | 50 ~ 80 | 80 ~ 110 | 110 ~ 160 | 160 ~ 200 |
Pānui:
Me tunu te hiko mō te 1 hāora i te pāmahana 250℃ i mua i te mahi 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 te kowiri tirahiko whakarewas, ngā irahiko whakarewa maitai waro, ngā irahiko whakarewa koranu iti, ngā irahiko whakarewa mata, ngā irahiko whakarewa koranu nikara me te koranu konumohe, ngā waea whakarewa maitai ngawari me te koranu iti, ngā waea whakarewa kowiri tira, ngā waea whakaheke hau-ārai, ngā waea whakarewa konumohe, ngā whakarewa pewa ruku. ngā waea, ngā waea whakarewa koranu nikara me te koranu konumohe, 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.
