ʻIkepili o nā mea Electrode no nā mīkini hoʻoheheʻe wahi kū'ē

ʻO ke kuʻi ʻana wahi kūʻē he ala i hoʻohana nui ʻia i nā ʻoihana like ʻole no ka hoʻohui ʻana i nā metala.ʻO ka maikaʻi a me ka maikaʻi o kēia kaʻina hana e hilinaʻi nui ʻia i nā mea i hoʻohana ʻia no nā electrodes welding.Ma kēia ʻatikala, e ʻimi mākou i nā kumu koʻikoʻi e noʻonoʻo ai i ke koho ʻana i nā mea electrode no nā mīkini welding wahi kū'ē.

1. Conductivity: He mea koʻikoʻi ka conductivity uila o ka mea electrode no ka hoʻoulu ʻana i ka wela i ka wā o ka wili ʻana.ʻO ke keleawe a me kona mau ala, e like me ka copper-chromium a me ka copper-zirconium, he mau koho kaulana ma muli o kā lākou conductivity uila kiʻekiʻe.Hāʻawi lākou i ka hoʻololi ʻana i ka ikehu maikaʻi a kōkua i ka hoʻokō ʻana i nā welds mau.
2. Heat Resistance: Hoʻopuka ka wiliwili wahi kūʻē i ka nui o ka wela, ʻoi loa ma nā wahi pili o nā electrodes.No laila, pono e loaʻa i ka mea electrode i koho ʻia ke kūpaʻa wela maikaʻi loa e kū i ka hana lōʻihi me ka ʻole o ka deformation a i ʻole degradation.Ua ʻike ʻia nā metala refractory e like me tungsten a me molybdenum no ko lākou kū ʻana i ka wela.
3. Paʻakiki: No ka hōʻoia ʻana i ka weld paʻa a paʻa, pono ka paʻakikī o ka mea electrode e pale aku i ka ʻaʻahu a me ka deformation i ka wā wili.Hiki i nā mea ʻoi aku ka paʻakikī ke mālama i ko lākou ʻano a hāʻawi i kahi ʻili wili hilinaʻi no ka manawa lōʻihi.ʻIke ʻia nā mea e like me ke keleawe-chromium-zirconium (CuCrZr) no ko lākou paʻakikī kiʻekiʻe a paʻa.
4. Thermal Conductivity: Ma waho aʻe o ka conductivity uila, ʻo ka thermal conductivity kekahi mea nui.ʻO ka hoʻopau ʻana i ka wela maikaʻi mai ka wahi weld he mea nui ia e pale i ka overheating a mālama i ka maikaʻi weld.ʻO nā electrodes i hoʻokumu ʻia i ke keleawe, ma muli o ko lākou conductivity thermal kiʻekiʻe, makemake pinepine ʻia no kēia kumu.
5. Kaʻina hana welding a me ka hoʻohālikelike waiwai: E noʻonoʻo i ke kaʻina hana wiliwili kūikawā a me nā mea i hui pū ʻia.Pono paha nā noi like ʻole i nā mea electrode ʻokoʻa.No ka laʻana, i ka wā e wili ai i nā kila ikaika, pono paha nā electrodes me ke kūpaʻa maikaʻi i ka lole a me ka deformation ma lalo o ke kaomi kiʻekiʻe.
6. Noʻonoʻo Kūʻai: Hiki ke ʻokoʻa ke kumukūʻai o nā mea electrode.ʻOiai ʻo nā mea e like me ke keleawe maʻemaʻe e hāʻawi i ka conductivity maikaʻi loa, ʻaʻole paha lākou e uku-pono no nā noi āpau.He mea nui ka hoʻokolo ʻana i nā pono hana me nā kaohi kālā.
7. Maintenance: He mea koʻikoʻi ka mālama ʻana i ka electrode maʻamau no ka lōʻihi o nā mea hana welding.Pono paha kekahi mau mea electrode i ka mālama pinepine ʻana ma mua o nā mea ʻē aʻe.E noʻonoʻo i ka maʻalahi o ka mālama ʻana i ke koho ʻana i nā mea electrode.

I ka hopena, ʻo ke koho ʻana i nā mea electrode e hana koʻikoʻi i ka hana a me ka maikaʻi o nā mīkini wiliwili wahi kū'ē.Pono nā mea ʻenekinia a me nā mea hana e loiloi pono i nā koi kikoʻī o kā lākou noi welding a koho i nā mea e hāʻawi i ke kaulike kūpono o ka conductivity, ka pale wela, ka paʻakikī, a me ka uku-pono.Pono e hoʻokō ʻia nā hana mālama kūpono e hōʻoia i ka lōʻihi o nā electrodes a me ka maikaʻi o ka weld.
