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

ʻO ke kuʻi ʻana wahi kūʻē he ʻenehana i hoʻohana nui ʻia i ka ʻoihana hana, hoʻohana ʻia e hoʻohui i nā ʻāpana metala ma o ka hana ʻana i kahi au uila kūloko ma ka wahi weld. He mea koʻikoʻi ke koho ʻana i nā mea electrode i ke kaʻina hana welding, e hoʻohuli ana i nā mea e like me ka weld quality, durability, a me ke kumu kūʻai.

1. Nā Electrodes keleawe

ʻO nā electrodes keleawe kekahi o nā koho maʻamau no nā mīkini wiliwili wahi kū'ē. ʻIke ʻia lākou no ko lākou maikaʻi wela a me ka uila conductivity, e kōkua i ka hana ʻana i ka wela e pono ai no ka welding. Hāʻawi nā electrodes keleawe i ka lōʻihi maikaʻi a hiki ke kū i nā wela kiʻekiʻe. Eia nō naʻe, maʻa mau lākou i ka wā a makemake paha e hoʻololi pinepine a mālama paha.

2. Nā Electrodes Tungsten

ʻO nā electrodes Tungsten kekahi koho ʻē aʻe no ka hoʻopaʻa ʻana i ka wahi kūʻē. Loaʻa iā lākou kahi helu hoʻoheheʻe kiʻekiʻe a me ka conductivity uila maikaʻi loa, e kūpono iā lākou no nā noi wili e pili ana i ka wela kiʻekiʻe a me ke kūpaʻa uila. Ua ʻike ʻia nā electrodes Tungsten no ko lākou lōʻihi, akā hiki ke ʻoi aku ke kumukūʻai ma mua e hoʻohālikelike ʻia i nā electrodes keleawe.

3. Nā mea hoʻohui metala refractory

Pono kekahi mau mea hoʻoheheʻe wahi kūʻē i nā wahi hoʻoheheʻe kiʻekiʻe a me ka lōʻihi ma mua o ka tungsten hiki ke hāʻawi. Ma ia mau hihia, hoʻohana ʻia nā mea hoʻoheheʻe metala e like me molybdenum a me tantalum. Hāʻawi kēia mau mea i ke kūpaʻa kūʻokoʻa i ka wela a me ka corrosion, i mea kūpono no nā hana wili kūikawā. Eia nō naʻe, hiki i kā lākou kumukūʻai kiʻekiʻe ke lilo i kumu palena no nā noi ākea.

4. Nā Electrodes Hui

Hoʻohui nā electrodes composite i nā mea like ʻole e hoʻokō i ke kaulike o nā waiwai. No ka laʻana, hoʻohui ʻia kahi electrode copper-tungsten composite i ka conductivity maikaʻi loa o ke keleawe me ke kūpaʻa kiʻekiʻe o ka tungsten. Hāʻawi kēia mau electrodes i ka hoʻohālikelike ma waena o ke kumukūʻai a me ka hana, e hana ana iā lākou i koho kaulana no nā noi welding he nui.

5. Electrode Coatings

I kekahi mau hihia, ua uhi ʻia nā electrodes me nā mea e like me ka chromium a i ʻole zirconium e hoʻomaikaʻi i ko lākou kūʻē ʻana i ka lole a me ka corrosion. Hiki i kēia mau uhi ke hoʻonui i ke ola o ka electrode a hoʻonui i ka maikaʻi o ka weld.

I ka hopena, ʻo ke koho ʻana o nā mea electrode no nā mīkini wiliwili wahi kūʻē e pili ana i nā ʻano like ʻole, me ka noi wili kūikawā, nā kumu kūʻai, a me nā ʻano hana i makemake ʻia. ʻO ke keleawe, ka tungsten, nā mea hoʻoheheʻe metala refractory, nā mea i hui pū ʻia, a me nā uhi electrode i loaʻa i kā lākou pono a me nā palena. Pono e loiloi pono nā ʻenekinia a me nā welders i kēia mau mea e koho i nā mea electrode kūpono loa no kā lākou pono, i ka hopena e hōʻoia i ka kūleʻa o ke kaʻina hana.
