Mālama ka hui i ka manaʻo kaʻina hana "ka hoʻokele ʻepekema, ke kūlana kiʻekiʻe a me ka maikaʻi, ka mea kūʻai kiʻekiʻe noKina OEM Welding Parts, Kuʻi ʻana o nā ʻāpana Kūʻai ʻo Carbon Steel, Ua loa'a mua i kā mākou hui nā hale hana ki'eki'e a me nā hui 'enehana loea ma Kina, e hā'awi ana i nā huahana maika'i loa, nā 'enehana a me nā lawelawe i nā mea kū'ai honua.ʻO ka ʻoiaʻiʻo kā mākou kumu, ʻo ka hana kūpono kā mākou hana, ʻo ka lawelawe kā mākou pahuhopu, a ʻo ka ʻoluʻolu o nā mea kūʻai aku ko mākou mua!
NĀ PALAPALA:
Hiki ke hoʻohana i ka corrosion kū'ē o ka kuhiliʻole kila, e like me ka 06Cr19Ni9 a me 06Cr19Ni11Ti, nona ka mahana hana ma lalo o 300 ℃;Hiki ke hoʻohana ʻia no ka hoʻolālā kila kila ma lalo o nā mahana cryogenic, e like me ka ipu wai nitrogen wai, nā ipu kinoea kūlohelohe, etc.
NA ANOAI:
ʻO E308-16 kahi ʻano rutile i uhi ʻia Cr18Ni9 kila kila.Hiki ke hoʻohana ʻia ʻo AC a me DC a hiki ke hoʻopili i nā kūlana āpau.Hiki iā ia ke hōʻea i ka hana kuʻi ʻana maikaʻi loa, kūpaʻa arc, liʻiliʻi spatter, maʻalahi ka wehe ʻana i ka slag a me ke ʻano weld maikaʻi.ʻO ka metala i waiho ʻia he kūpaʻa maikaʻi i ka corrosion inter granular.
NĀ MEA:
1. Pono e hoʻomoʻa ʻia nā electrodes e 320-350 ℃ no 1 hola ma mua o ke kuʻi ʻana, e hoʻomaloʻo i ka electrode i ka wā e hoʻohana ai.
2. Pono e hoʻoneʻe ʻia ka ʻōpala, ka ʻaila, ka wai a me nā mea haumia ʻē aʻe o ka weld ma mua o ke kuʻi ʻana.
3.Recommended DC mana lako, no ka mea, AC kuʻihao he pāpaʻu komo, ka manawa e ole e nui loa, i mea e pale aku i ka uhi 'ulaʻula a me ka pohā.
4. No ka ho'ēmiʻana i ka nui o ka hoʻokomo wela a me ka welding electrode oscillating amplitude ʻaʻole pono e nui loa.
5. Pono ka wela mua a me ka interlayer ma lalo o 150 ℃
