Hāʻawi ʻo Ningbo De-Shin i ka piha piha o ke keleawe tungsten (6 ~ 50wt.% Cu) no nā ʻano noiʻi ʻoihana like ʻole.Lawe ʻo ia i ke kaʻina hana infiltration vacuum holomua a hoʻokō nā huahana āpau i ka criterion o GB/T 8320-2003, ASTM B 702-93(Apono hou ʻia 2004).ʻO ka tungsten keleawe he pseudo-alloy a paʻa ia i ka hiki ke pale aku i ka tungsten a me ka conductivity uila kiʻekiʻe o ke keleawe.
Kaʻina hana:hui pauda -> kaomi -> hoʻopaʻa ʻia -> hoʻoheheʻe ʻana i ka lepo -> hoʻoheheʻe ʻia -> QC.Hoʻopili paʻa ʻia kēia kaʻina hana āpau e QC e hōʻoia i ka hana maikaʻi loa.
Pono:
1. Hoʻohui pū ʻia ke kūpaʻa arc kiʻekiʻe me ka conductivity uila maikaʻi.
2. Kiʻekiʻe thermal conductivity.
3. Hoʻonui wela haʻahaʻa.
Nā noi:
1. Hoʻopili ʻia nā mea hoʻopili a me nā mea hoʻoheheʻe maloʻo i nā mea haʻihaʻi uila kiʻekiʻe a me waena a i ʻole nā mea hoʻokaʻawale.
2. Electrodes i nā mīkini ʻoki uila.
3. Hōʻikeʻike Huahana!Piʻi ka wela ma ke ʻano he mea hoʻoluʻu passive o nā mea uila a me nā mea hoʻopili uila.
4. Electrodes no ke kuʻi kuʻi ʻana.
Nui waiwai:
Koʻokoʻo tungsten keleawe: diameter≥0.5mm;lōʻihi≤300mm.
Ke keleawe tungsten pā: thickness≥1.0mm;lōʻihi & laula≤300mm.
