No ke aha e pono ai ke koho ʻia ʻana o ka Electrode Kūikawā ʻo Copper Wire Spot Weld
He kiʻekiʻe loa ka uila a me ka wela o ke keleawe. ʻOiai he mea maikaʻi kēia i nā noi uila, hana ia i nā pilikia i ka wiliwili wahi:
- ʻO ka conductivity kiʻekiʻe + ka hoʻopau wela wikiwiki: Laha koke ka ikehu mai ka lae weld, e paʻakikī ai ka hoʻohui pono ʻana.
- ʻO nā pilikia o ka oxidation a me ka pili: Hoʻopaʻa maʻalahi ke keleawe ma lalo o ka wela kiʻekiʻe a pili i ka electrode, e ʻoi aku ka wikiwiki a me ka maikaʻi weld paʻa ʻole.
- ʻO ke kaumaha mechanical a me ka wela kiʻekiʻe: I ka wā wiliwili wahi, pono nā electrodes e kū i ke kaomi, ka hopena o kēia manawa, a me nā pōʻai wela.
No laila, pono nā mea electrode e hāʻawi i ka hana kiʻekiʻe, ka lōʻihi, ka pale ʻana i ka wela, a me ka hana anti-adhesion e hōʻoia i ka maikaʻi o ka wiliwili, ka ikaika weld, a me ke ola o nā lako.
Nā Mīkini wiliwili no ke keleawe - MFDC a me nā mea hoʻoheheʻe kapasitor
I ka hana hou ʻana, ʻelua ʻano mea hana maʻamau i hoʻohana ʻia no ka wili uea keleawe:
Hāʻawi i ka puka paʻa a hiki ke mālama ʻia. Kūpono no nā noi e koi ana i ka maikaʻi weld mau.
E hoʻokuʻu i ke au kiʻekiʻe i loko o ka manawa pōkole loa, kūpono no nā uwea keleawe lahilahi a me ka -wikiwiki kiʻekiʻe.
Ma waho o ke ʻano mīkini, pono ke koho electrode i ka mea a me ka noi.
Nā Mea Electrode a me nā hiʻohiʻona hoʻohana
| Mea Electrode | Nā mea nui | Manaʻo ʻia ka hoʻohana / keleawe mānoanoa | Manaʻo ʻia nā ʻōnaehana mīkini |
| Ke keleawe maʻemaʻe (T2 / TU1) | ʻOi loa ka uila a me ka wela | Uea keleawe lahilahi (1-2 mm) | Pukiki pōkole 0.1–0.3 s, kaomi haʻahaʻa ma kahi o . 0.3 MPa |
| Kromium Zirconium Copper (C18150) | ʻO ka conductivity kiʻekiʻe (~ 85% IACS), hoʻomaikaʻi i ka ikaika a me ke kūpaʻa ʻaʻahu | keleawe -mānoanoa (3–6 mm) | ʻO -frequency kiʻekiʻe 1–5 kHz i kēia manawa, pono ka hoʻoluʻu ʻeleu |
| Ke keleawe Tungsten (CuW70 / CuW80) | Kūleʻa wela koʻikoʻi, mālama i ke ʻano i ʻoi aku ma mua o a i ʻole like me 1000 degere | Nā ʻāpana keleawe mānoanoa ( ʻoi aku ma mua o a i ʻole like me 5 mm) | Kiʻekiʻe o kēia manawa 60-80 kA, kiʻekiʻe electrode ikaika |
| Ke keleawe hoʻopuehu ʻoxide (OD{0}}Cu) | ʻOi aku ka maikaʻi o ka -adhesion & wear resistance | ʻO ka wili pololei, nā ʻano paʻakikī, ka hana paʻa | ʻO ka wiliwili puʻupuʻu lehulehu, ka mana wela i hoʻonui ʻia |
Nānā: 100% IACS=conductivity o ke keleawe maʻemaʻe. Hāʻawi ʻo C18150 i ka 85% IACS akā ʻoi aku ka lōʻihi o ka lōʻihi a me ke kūpaʻa wela.
Pehea e hoʻonui ai i kāu mau hoʻonohonoho Spot Welder
He mea koʻikoʻi ka hoʻoponopono ʻana i nā ʻāpana kūpono no ka hoʻokō ʻana i ka maikaʻi weld paʻa:
1. Ka manawa a me ka welding time
- Uea keleawe lahilahi: E hoʻohana i nā puʻupuʻu pōkole (0.1-0.3 s) e hoʻemi i ka wela.
- ʻāpana keleawe waena/mānoanoa: E hoʻonui i kēia manawa, e hoʻolōʻihi i ka manawa weld, a i ʻole e hoʻohana i nā kaʻina puʻupuʻu lehulehu.
2. Electrode Pressure
- Uea lahilahi: approx.0.3 MPa
- Nā ʻāpana keleawe mānoanoa:0.5 MPa a i ʻole
3. Koi hooluolu
- mālamaʻOi aku a i ʻole like me 60 L/minke kahe hooluolu no C18150, CuW, a me OD{1}}Cu electrodes.
- Kāohi i ka wela nui, deformation, a me ka hoʻohana wikiwiki ʻana.
4. Mālama mau
- E hoʻololi i nā electrodes ke emi ke anawaena o ka pikoʻOi aku ma mua a i ʻole like me 20%.
- E hoʻomaʻemaʻe pinepine i ka ili electrode e wehe i ka oxidation a me nā waihona keleawe.
- E hoʻohana i ka nānā ʻana i ka PLC no ka paʻa o kēia manawa, kaomi, a me ka hoʻomaha.
Pehea ka pili ana o na mea Electrode i ka maikai a me ke ola o na lako
- ʻOi aku ka maikaʻi o ka hoʻoili ʻana i ka ikehu
- E hoʻohana i ke kūpaʻa → ʻoi aku ka lōʻihi o ke ola electrode a me ka liʻiliʻi o nā mea pani
- Kūleʻa wela → hoʻokumu ʻia ʻana o ka weld nugget
- Anti-adhesion → liʻiliʻi nā mea haumia a me ka maikaʻi wiliwili paʻa
ʻO ke koho ʻana i ka electrode kūpono e hōʻemi nui i ka loli, hoʻomaikaʻi i ke kūlike o ka welding, a hoʻohaʻahaʻa i nā kumukūʻai hana.
Alakaʻi Koho Electrode wikiwiki
- Uea keleawe lahilahi (1–2 mm) → Copper Ma'ema'e
- keleawe -mānoanoa (3–6 mm) → C18150
- Nā ʻāpana keleawe mānoanoa ( ʻoi aʻe a like paha me 5 mm) → CuW70 / CuW80
- Pono a i ʻole nā mea hoʻopili -adhesion → OD-Cu
Nā hewa maʻamau e hōʻalo ai
- "ʻOi aku ka maikaʻi o ka conductivity kiʻekiʻe."
He maikaʻi ke kalaiwa maʻemaʻe akā ʻaʻahu hikiwawe-pono ʻole no ka wiliwili ʻana-kiʻekiʻe.
- "ʻAʻole pono nā electrodes i ka mālama."
ʻAʻole hiki ke hoʻohana ʻia ka electrode wear, oxidation, a me deformation.
- "Hoʻokahi ʻāpana kūpono i nā welds keleawe a pau."
Pono kēlā me kēia mānoanoa a me ka hoʻohana ʻana i nā ʻāpana kuʻihao maʻamau.
Ka hopena
I ka welding wahi uea keleawe, koho i ka pono electrode mea koʻikoʻi.
Ma o ke koho pono ʻana i nā mea waiwai, ka hoʻoponopono ʻana i nā ʻāpana kūpono, a me ka mālama mau ʻana, hiki i nā mea hana ke hoʻomaikaʻi nui i ka paʻa ʻana o ka welding, hoʻemi i ka lole electrode, a hoʻomaikaʻi i ka hana pono.
ʻO ke koho ʻana i ka electrode kūpono e hōʻoiaʻiʻo ai i kāu mīkini wiliwili wahi e hāʻawi like a hilinaʻi welds ma na mea keleawe a pau.
