Ma alloys amkuwa amagwiritsidwa ntchito kwambiri pamagetsi, zida zamagalimoto, ndi zida zapakhomo chifukwa champhamvu kwambiri yamagetsi, kukana dzimbiri, komanso makina amakina. Komabe, zomwezi zimapangitsa kuwotcherera kwa malo kukhala kovuta kwambiri poyerekeza ndi chitsulo kapena aluminiyamu.
Kuti mukhale ndi-zowotcherera zabwino kwambiri pamafunika kumvetsetsa kachitidwe ka copper alloy ndikugwiritsa ntchito njira zoyenera zowotcherera. Bukuli likufotokoza momwe mungawotcherera bwino ma aloyi amkuwa pogwiritsa ntchito amakina kuwotcherera malo, yokhala ndi data-yothandizira komanso mayankho othandiza pakupanga mafakitale.
Chifukwa Chake Ma Aloyi A Copper Ndi Ovuta Kuwona Weld
Zosakaniza zamkuwa ndi zamkuwa zimakhala ndi zovuta zowotcherera:
1. Kuthamanga Kwambiri Kwambiri Kwambiri
Ma aloyi amkuwa amatenthetsa nthawi 7-11 mwachangu kuposa chitsulo cha carbon.
→ Kutentha kumafalikira kutali ndi malo owotcherera nthawi yomweyo, zomwe zimapangitsa kupanga nugget kukhala kovuta.
2. Kukana kwa Magetsi Ochepa
Kukaniza pang'ono kumapangitsa kuti mapano adutse mosavuta, kumachepetsa kutulutsa kutentha komwe kumalumikizana.
→ Izi zimawonjezera mwayi wa ma welds ofooka kapena kusakwanira kokwanira.
3. Fast Kuzirala Mitengo
Kuziziritsa msanga kungayambitse porosity, ming'alu, ndi kukula kosafanana kwa nugget-makamaka mkuwa, bronze, ndi{1}}zinc alloys apamwamba.
Chifukwa cha izi, makina opangira makina opangira zitsulo si oyenera ma aloyi amkuwa. Maelekitirodi apadera komanso kuwongolera moyenera magawo ndikofunikira.
Kusankha Ma Electrodes Oyenera a Copper Alloy Welding
1. Sankhani Zida Zopangidwira Zapamwamba-Zochita Zapamwamba
Maupangiri ovomerezeka amawotchera amalangiza:
| Mtundu wa Copper Alloy | Analimbikitsa Electrode |
|---|---|
| Kuchita bwino-kwapamwamba (monga, Cu-Cr, Cu-Zr) |
Maelekitirodi a Class 1 (kubalalika{1}}mkuwa wolimba) |
| Ma aloyi apansi-opangira ma conductivity (mkuwa, bronze) | Class 2 copper alloy electrodes |
Kusankhidwa koyenera kwa ma elekitirodi kumatsimikizira kuyenda kokhazikika komanso kumachepetsa kutayika kwa kutentha.
2. Gwiritsani Ntchito Ma Electrodes Ophatikiza okhala ndi Tungsten Insert
Pazovuta zowotcherera za Copper alloy:
- Ma electrode a Tungsten amachepetsa kutentha kwa electrode.
- Tungsten ili ndi malo osungunuka3420 digiri, kwambiri kuposa mkuwa.
- Analimbikitsa tungsten nsonga awiri:3-4 mm.
- Imawongolera kwambiri mapangidwe a nugget ndikuchepetsa kumamatira kwa electrode.
Mayankho a electrode awa amatsimikiziridwa kwambiri pakupanga magalimoto ndi zamagetsi.
Kukhathamiritsa Zowotcherera Zowotcherera za Copper Alloy Spot Welding
Kuti mukwaniritse ma welds okhazikika, anumakina kuwotcherera maloziyenera kukhazikitsidwa ndi magawo enieni.
1. Panopa ndi kuwotcherera Time
- Gwiritsani ntchito nsonga yocheperako poyerekeza ndi kuwotcherera kwachitsulo.
- Chepetsani nthawi yowotcherera kuti musunge kutentha kwambiri.
- Makina a MFDC (Medium Frequency Direct Current) amawongolera bwino mapepala owonda (<1.5 mm).
- Kukonza bwino-kukufunika pamtundu uliwonse wa aloyi yamkuwa chifukwa magetsi/matenthedwe amasiyana kwambiri.
2. Njira Kukhathamiritsa Malangizo
- Tsukani bwino pamwamba kuti muchotse mafuta, ma oxide, fumbi, ndi zinyalala zoyala.
- Ikani mphamvu yofinya yokwanira kuti mutsimikize kukana kulumikizana.
- Gwiritsani ntchito kutentha-zotchingira shimu kapena zolumikizira pakafunika.
- Onetsetsani kuti makina owotcherera ndi kuwongolera mphamvu kumasinthidwa pafupipafupi.
Kuthetsa Mavuto a Common Copper Alloy Welding
1. Kumamatira kwa Electrode
Chifukwa:
- Kutentha kwambiri pa mawonekedwe
- Electrode kufewetsa kapena kuipitsidwa
Zothetsera:
- Onjezerani ma electrodes a tungsten composite
- Chepetsani masiku ano / kuchepetsa nthawi yowotcherera
- Limbikitsani kuziziritsa ndikuchita ma elekitirodi pafupipafupi
2. Kusakwanira kwa Weld Mphamvu
Chifukwa:
- Kutentha kumafalikira mofulumira kwambiri
- Kukula koyipa kwa nugget
Zothetsera:
- Wonjezerani mphamvu yofinya
- Onjezani nthawi yowotcherera pang'ono
- Onetsetsani kutulutsa kofanana kuchokera kwa wowongolera
- Chotsani chogwirira ntchito bwino kwambiri
Zochita Zabwino Kwambiri pa Consistent Copper Alloy Weld Quality
Kuti mukhalebe-kukhazikika ndi kubwerezabwereza:
- Pangani-ma curve enieni
- Yang'anani ndi kuvala maelekitirodi nthawi zonse
- Yendetsani ma welds oyesa pagulu lililonse latsopano la aloyi
- Jambulani zophatikizika bwino za parameter
- Yang'anirani zomwe zikuchitika mu weld current, mphamvu, ndi kukula kwa nugget
Mchitidwewu umachepetsa kwambiri chiwopsezo cha kulephera-m'malo opanga.
Kutsimikizira Ubwino ndi Njira Zoyesera
Kutsimikizira kudalirika kwa weld:
- Kuyesa koononga (kumeta ubweya, kukangana, kudutsa-kuwunika magawo)
- Mayeso a peel kuti atsimikizire kuchuluka kwa nugget ndi kuphatikiza
- Kuyang'ana kowoneka kwa ming'alu, porosity, ndi kutentha kwambiri
- Kuwunika kosasinthika kwa parameter pa chowongolera ndi chosinthira
Kulemba zotsatira izi kumathandiza kusunga miyezo ya satifiketi ndi zofunikira zapadziko lonse lapansi.
Mapeto
Ndi zida zolondola zama elekitirodi, makonda okhathamiritsa, komanso kuwongolera khalidwe labwino, amakina kuwotcherera maloamatha kupeza ma welds amphamvu komanso odalirika pazitsulo zamkuwa. Poyang'anira kutentha kwa kutentha, kukhazikika kwa kuthamanga, ndikuletsa kuwonongeka kwa electrode, opanga amatha kuthana ndi zovuta zomwe zimachitika chifukwa cha kuwotcherera aloyi yamkuwa.
Kudziwa bwino njirazi sikumangowonjezera mphamvu zowotcherera komanso kumapangitsa kuti zinthu zikhale zolimba komanso kusasinthika kwamakampani monga zamagetsi, zamagalimoto, zosungirako mphamvu, ndi zida zamagetsi.
