He aha ka ʻokoʻa ma waena o Thoriated Tungsten a me Lanthana Electrodes?

2. Nā hiʻohiʻona hana:

Ka hana hoʻokuʻu uila

Thoriumtungsten electrode: Ma muli o ka palaho radioactive o ka mea thorium, e hana ʻia kekahi mau electron manuahi ma ka ʻili o ka electrode. Ke kōkua nei kēia mau electron i ka hoʻohaʻahaʻa ʻana i ka hana hana o ka electrode, a laila e hoʻoikaika ai i ka hiki ke hoʻokuʻu electron. Hiki iā ia ke hoʻokuʻu i nā electrons i ʻoi aku ka paʻa i nā haʻahaʻa haʻahaʻa, kahi e hana maikaʻi ai i kekahi mau manawa e like me ke kuʻi ʻana o AC kahi e koi ʻia ai ka hoʻomaka ʻana o ka arc.

Lanthanum tungsten electrode: He maikaʻi nō hoʻi ka hana hoʻokuʻu electron. ʻOiai ʻaʻohe radioactive auxiliary electron emission, hiki i ka lanthanum oxide ke hoʻomaʻemaʻe i ke ʻano o ka palaoa o ka tungsten a mālama i ka electrode i kahi paʻa electron emission maikaʻi i ka wela kiʻekiʻe. Ma ke kaʻina hana hoʻoheheʻe DC, hiki iā ia ke hāʻawi i kahi arc paʻa a hoʻonui i ka maikaʻi o ka welding.

Ke kū'ē ahi

thorium tungsten electrode: I loko o kahi kiʻekiʻe wela, ma muli o ke alo o ka thorium oxide, hiki ke hoʻomaikaʻi ʻia ka pale ahi o ka electrode i kekahi ʻano. Eia nō naʻe, me ka hoʻonui ʻana o ka manawa hoʻohana a me ka hoʻonui ʻana o ka welding i kēia manawa, e wela mau ke poʻo electrode i kekahi ʻano.

Lanthanum tungsten electrode: Loaʻa iā ia ka pale ahi maikaʻi. Hiki i ka Lanthanum oxide ke hana i kahi kiʻiʻoniʻoni pale ma ka ʻili electrode i ka wela kiʻekiʻe e pale aku ai i ka oxidation a me ka puhi ʻana o ka tungsten. I ka wā o ka wiliwili kiʻekiʻe o kēia manawa a i ʻole nā ​​​​hana wili lōʻihi, hiki i ke ʻano hope o ka lanthanum tungsten electrode ke kūpaʻa mau, e hōʻemi ana i ka nui o nā mea hoʻololi electrode pinepine.

Hana hoʻomaka ʻo Arc

ʻO Thorium tungsten electrode: He mea maʻalahi ka hoʻomaka ʻana i ke arc, no ka mea, ʻo kāna hana haʻahaʻa haʻahaʻa e hiki ai ke hoʻokumu ʻia kahi ala conductive ma waena o ka electrode a me ka weldment me ka wikiwiki i ka wā o ka hoʻomaka ʻana o ke arc, a hiki ke hoʻāla ʻia ke arc me ka maʻalahi.

Lanthanum tungsten electrode: ʻO ka hana hoʻomaka arc he haʻahaʻa iki ma mua o ka thorium tungsten electrode, akā ma lalo o nā hoʻonohonoho hoʻonohonoho hoʻohālikelike pono, hiki ke hoʻokō i kahi hopena hoʻomaka maikaʻi. A hana maikaʻi ʻo ia i ka paʻa arc ma hope o ka hoʻomaka ʻana o ke arc.

3. Nā hiʻohiʻona noi

Thoriumtungsten electrode

Ma muli o kāna hana hoʻokuʻu electron maikaʻi a me ka hoʻomaka ʻana o ka arc, hoʻohana pinepine ʻia i ka AC argon arc welding, ʻoi aku hoʻi i ka wā e wili ai i ka aluminika, ka magnesium a me kāna mau ʻāpana a me nā mea ʻē aʻe me nā koi hoʻomaka arc kiʻekiʻe. Eia nō naʻe, ma muli o ka loaʻa ʻana o ka radioactivity, ua kaupalena ʻia kona hoʻohana ʻana i kekahi mau manawa me nā koi pale radiation koʻikoʻi, e like me ka hana ʻana i nā lāʻau lapaʻau, nā ʻoihana meaʻai meaʻai a me nā kula ʻē aʻe.

Lanthanum tungsten electrode

No ka mea, ʻaʻohe pōʻino radioactive, ʻoi aku ka laulā o kāna mau noi. Hiki ke hoʻohana ʻia i ka DC argon arc welding a me kekahi AC argon arc welding scenarios. I ka wā e wili ai i nā mea e like me ke kila kila, ke kila kalapona, ke keleawe keleawe, a me nā mea ʻē aʻe, hiki iā ia ke hoʻokō i kāna hana paʻa arc a me ke kūpaʻa ahi maikaʻi e hōʻoia i ka maikaʻi wili.

4. Palekana

ʻO ka thorium tungsten electrode: No ka mea, aia ka thorium oxide, kahi mea radioactive, e hana ia i kekahi mau pōʻino radioactive i ka wā e hoʻohana ai. Inā hōʻike ʻia no ka manawa lōʻihi, hiki ke loaʻa nā hopena maikaʻi ʻole i ke olakino o nā mea hana, me ka hoʻonui ʻana i ka pilikia o nā maʻi e like me ke kanesa. No laila, i ka wā e hoʻohana ai i nā electrodes tungsten thoriated, pono e lawe ʻia nā hana palekana radiation, e like me ke komo ʻana i nā lole pale a me ka hoʻohana ʻana i nā mea nānā radiation.

ʻO Lanthanum tungsten electrodes: ʻaʻole i loaʻa nā mea radioactive, palekana, a ʻaʻole pono e hopohopo e pili ana i ka radioactive contamination i ka wā o ka hoʻohana ʻana, e hālāwai me ka mālama ʻana i ke kaiapuni a me nā koi olakino a palekana.
