I ka hana ʻenehana hou, ua lilo ka mīkini wiliwili wahi i mea pono no nā noi hoʻohui metala. ʻO nā electrodes, ma ke ʻano he mea koʻikoʻi i ke kaʻina hana welding, pili pono i ka maikaʻi weld, ka lōʻihi o nā mea hana, a me ka hana pono. Nānā kēia alakaʻi i nā mea electrode maʻamau nomīkini wiliwili wahinā noi, ke kālailai ʻana i kā lākou mau hiʻohiʻona hana a me nā hiʻohiʻona hana kūpono.
1. No ke aha he mea nui ka Electrode Material
Ma ka wiliwili wahi kū'ē, ʻoi aku ka ʻoi aku o ka electrode ma mua o ka mea hoʻokele maʻalahi - e hoʻoholo pololei i ka maikaʻi o ka weld, ka paʻa, ke ola o nā mea hana, ke alapine o ka mālama ʻana, a me ka huahana holoʻokoʻa. ʻO ke koho ʻana i ka mea kūpono e kōkua iā ʻoe:
- Hoʻonui i ka uila a me ka wela no ka hoʻokumu ʻana i ka weld paʻa
- E hoʻomaikaʻi i ka paʻakikī, ka hoʻopaʻa ʻana, a me ka hana hoʻomāmā -anti
- E ho'ēmi i ka pinepine o ka hoʻololi a me ka manawa hoʻomaha o ka mīkini
- E hōʻoia i nā nuggets weld mau i ka hana nui -nui
No laila, ʻo ke koho ʻana i nā mea electrode kūpono e hoʻohālikelike i kāu mea hana, nā ʻāpana welding, a me ka ʻenehana hana e pono ai no ka kāohi ʻana i ke kumukūʻai a loaʻa i nā hopena weld hilinaʻi.
2. Mea Electrode ma'amau a me ko lakou mau ano
Aia ma lalo iho kahi hi'ohi'ona o nā mea electrode i ho'ohana nui 'ia i kēia mau lā - mai ke keleawe -conductivity ki'eki'e a hiki i ka-pa'a pa'a ki'eki'e.
Kiekie -Conductivity, Non{1}}Heat-Treatable Copper Electrodes
Ke keleawe maʻemaʻe (T2 / TU1)
Pono:ʻO ka conductivity kiʻekiʻe loa (≈100% IACS) a me ka hoʻokele wela maikaʻi loa. He kūpono no nā mea e koi ana i ka hoʻoili uila/wela kiʻekiʻe, e like me ke kaula keleawe lahilahi, nā metala i uhi ʻia, a i ʻole nā mea palupalu e like me ka alumini.
Nā hemahema:Haahaa loa paakiki; deforms maʻalahi ma lalo o ke kaomi. ʻAʻole kūpono no ka -frequency kiʻekiʻe a i ʻole ka -volume kiʻekiʻe.
Kelepona Chromium (CuCr / RWMA Papa 2)
Pono:ʻO ka hoʻoili uila maikaʻi (80-90% IACS) me ka ʻoi aku ka ʻoi aku o ka paʻakikī (HRB 80-90) ma mua o ke keleawe maʻemaʻe. He kūpono no nā pā keleawe -mānoanoa, kila hao, a me ke kila kalapona.
Hoʻohana maʻamau:Nā ʻāpana kaʻa, nā ʻāpana kila, ka pepa maʻamau -weli metala.
Hōʻuluʻulu manaʻo:
ʻO ke keleawe maʻemaʻe=maikaʻi loa, haʻahaʻa loa ka lōʻihi
Kromium copper=kaulike maikaʻi no ka hapa nui o nā hana kuʻikuʻi -hana
Pumehana
CuCrZr (Copper–Chromium–Zirconium Alloy / RWMA Papa 2)
- ʻO ka paʻakikī ma hope o ka mālama ʻana i ka wela:ʻOi aku a i ʻole like me 80 HRB
- Ka hoʻoili uila:74–85% IACS
- ʻIke ʻia no ka hoʻokō ʻana i ka -hoʻopalupalu maikaʻi, paʻa ka wela, a me ke kūpaʻa ʻaʻahu.
- ʻO ke kūlana ʻoihana no ka hana ʻana i nā kaʻa, nā laina automation, a me ka hana mau.
Hoʻopuehu-Ke keleawe i hoʻoikaika ʻia (DSC / GlidCop / Cupal)
- ʻOi aku ka paʻa wela ma lalo o nā pōʻai hoʻomehana mau
- Ka liʻiliʻi o ka paʻakikī ma hope o ka -hoʻohana lōʻihi
- Kūikawā no ka -frequency kiʻekiʻe, kiʻekiʻe-ka wiliwili kiko ma ka hana ʻoihana.
Hōʻuluʻulu manaʻo:
Hāʻawi nā huila CuCrZr a me DSC i ke kaulike holoʻokoʻa maikaʻi loa o ka conductivity, ka lōʻihi, a me ke ola - kūpono no ka hana nui.
'O'ole'a Ki'eki'e / Mahana Ki'eki'e
Ke keleawe–Tungsten (CuW70 / CuW80)
- Hoʻohui i ka paʻakikī a me ka helu heheʻe me ka conductivity keleawe
- Ka lawe ʻana: 40–60% IACS
- Kūleʻa maikaʻi i ka wela kiʻekiʻe, spatter, a me ke arc erosion
- Kūpono no:
Kila kohu ʻole
kila ikaika -kiʻekiʻe
Nā papa mānoanoa
Kiʻekiʻe -kuʻihao o kēia manawa
Nā hemahema:ʻOi aku ke kumukūʻai, ʻoi aku ka paʻakikī i ka mīkini, haʻahaʻa haʻahaʻa.
Nā Alloy Paʻa ʻē aʻe (Ni–Cu, Ni–Si–Cu, Co–Be–Cu, etc.)
Hoʻohana ʻia ma kahi e koi ʻia ai ke kūpaʻa ʻaʻahu a i ʻole ka ikaika compressive kiʻekiʻe, ʻoiai ʻoi aku ka haʻahaʻa o ka conductivity.
Hōʻuluʻulu manaʻo:
No nā mea kila -kiʻekiʻe, mānoanoa, a i ʻole nā kila ikaika -kiʻekiʻe → koho CuW a i ʻole -kiʻekiʻe ʻeleʻele keleawe.
3. Pehea e koho ai i ka mea Electrode Pono
Pono ʻoe e koho i ka electrode e pili ana i ka mea hana hana + nā ʻāpana kuʻi + koi hana + kumukūʻai.
| Kumu Loiloi | Ka mea e noonoo ai |
| ʻAno mea hana | Nā metala hoʻoili kiʻekiʻe (Cu, Al) → -electric conductivity kiʻekiʻe; ʻO nā huila -ikaika kiʻekiʻe → nā ʻeleka paʻa a me ka wela-. |
| Nā Kūlana Welding | ʻOi aku ka nui o kēia manawa a me ka wela → ʻoi aku ka ikaika, ʻoi aku ka paʻakikī, ʻoi aku ka -mea hoʻopalupalu |
| Volume Hana | Ka 'akomi a me nā pō'ai alapine ki'eki'e |
| Kūʻai Kūʻai | ʻO nā mea kiʻekiʻe-e hōʻemi ana i ka wā hoʻomaha a me ke kumukūʻai holoʻokoʻa ʻoiai ke kumu kūʻai kiʻekiʻe |
ʻAʻohe mea uila - maikaʻi loa o ke ao holoʻokoʻa wale nō ka hoʻokūkū maikaʻi loa no kāu noi wiliwili.
4. Nā mea hana kūikawā
No ka -mahanahana kiʻekiʻe, kiʻekiʻe-mea hoʻoheheʻe wela, ʻoi aku ka maikaʻi o ka mīkini wiliwili wahi me nā mea i hoʻopaʻa ʻia i ka pauda:
Tungsten -Alloy Copper (CuW70/CuW80)
- Maʻiʻo Tungsten: ʻoi aku ka nui a i ʻole like me 70%
- Ka helu hehee: ʻoi aku ma mua o 1000 degere
- Conductivity: 40-60% IACS (pili pili i ka ʻike tungsten)
- Noi: Ke kila kuhiliʻole kaumaha, wiliwili alumini
- ʻOi aku ka maikaʻi o ka pale ʻana i ka arc erosion no ka koi ʻana i nā hana mīkini wiliwili wahi
Kāleka -Tungsten Alloys
- ʻOi aku ka maikaʻi o ka pale ʻana a me ka conductivity
- ʻO ka paʻakikī kūpono a me ka pale wela
- Nā mea hoʻohana: ʻO ka hoʻoheheʻe pololei ʻana a i ʻole nā hiʻohiʻona kiʻekiʻe -pilikia
- He kūpono no ka wili pila pila me ka mīkini wiliwili wahi
5.He aha nā mea āu e koho ai?
- ʻO ke keleawe lahilahi / nā metala palupalu / haʻahaʻa -welikini i kēia manawa → Ke keleawe maʻemaʻe / Chromium Copper
- Ke kila galvanized / carbon steel / stainless steel / hana nui nui → CuCrZr a i ʻole DSC Copper
- Mea mānoanoa / kila kuhiliʻole / kiʻekiʻe -ʻeleu ikaika / kiʻekiʻe-kuʻihao o kēia manawa → Copper–Tungsten (CuW)
Ma ka hoʻohālikelike ʻana i nā mea uila me ke ʻano mea hana, nā kūlana wili, a me ka nui o ka hana, hiki iā ʻoe ke hoʻomaikaʻi nui i ka hana weld me ka hoʻohaʻahaʻa ʻana i -kumukūʻai hana lōʻihi.
Ka hopena
Electrode koho no koumīkini wiliwili wahiPono e noʻonoʻo pono i nā koi welding, nā ʻano mea, a me nā ʻāpana kaʻina. Mai ka -conductivity kiʻekiʻe ke keleawe maʻemaʻe a hiki i ka wela-tungsten{3}}ʻeleu keleawe, hāʻawi kēlā me kēia mea i nā pōmaikaʻi kūʻokoʻa no nā noi kikoʻī e like me ka wiliwili-pā, ka hana ʻāpana kaumaha, a me nā hiʻohiʻona pololei.
Ma o ka hoʻohālikelike ʻana i nā mea ʻepekema, ka hoʻoponopono pololei ʻana i nā ʻāpana, a me nā protocols mālama ʻōnaehana, hiki i nā mea hana ke hoʻomaikaʻi nui i ka maikaʻi o ka welding a me ka pono hana.
ʻO ke koho electrode kūpono e hōʻoia i kāu mīkini wiliwili wahi e hāʻawi i ka hana kūpaʻa a hilinaʻi ma waena o nā noi ʻoihana like ʻole.
