Kuthetsa Mavuto Wamba Wowotcherera Ndi Malangizo a Tungsten Carbide Saw

    Welding tungsten carbide (WC) adawona malangizo a zida zodulira ndi njira yovuta kwambiri yomwe imakhudza magwiridwe antchito komanso moyo wautali wa zida. Komabe, njirayi nthawi zambiri imatha kupereka zovuta zomwe, ngati sizinayankhidwe, zingayambitse kulephera kwa mankhwala omaliza. Kumvetsetsa nkhani zowotcherera wamba ndi mayankho ake ndikofunikira kuti muwonetsetse kuti ma welds apamwamba komanso magwiridwe antchito abwino kwambiri. Nkhaniyi ikufotokoza za mavuto omwe amakumana nawo pakuwotcherera maupangiri a tungsten carbide ndipo imapereka njira zothetsera mavuto.

1. Kulowa kosakwanira

Vuto: Kulowa kosakwanira kumachitika pamene weld samalowa mokwanira m'zinthu zoyambira, zomwe zimatsogolera kumagulu ofooka omwe amatha kulephera kupsinjika.

Zomwe zimayambitsa: Kutentha Kochepa: Kusatentha kokwanira kungalepheretse kusungunuka koyenera kwa zinthu zoyambira.

Ma Electrode Positioning Olakwika: Ngodya yolakwika kapena mtunda ukhoza kuchepetsa kutentha kwabwino.

Mayankho: Sinthani Zowotcherera Zowotcherera: Wonjezerani ma amperage ndi ma voliyumu kuti mupereke kutentha kwambiri. Onetsetsani kuti liwiro laulendo ndiloyenera kuti mulole kusungunuka kokwanira.

Konzani ngodya ya Electrode: Ikani ma elekitirodi pa ngodya yoyenera ndi mtunda kuti muwonetsetse kuti kutentha kumagawidwa.

2. Kusweka mu Weld

Vuto: Kung'amba kumatha kuchitika mu weld bead kapena zone yokhudzidwa ndi kutentha (HAZ), zomwe zimapangitsa kuti pakhale zovuta kwambiri.

Zomwe zimayambitsa: Kutentha Kwambiri: Kutentha kwambiri kungayambitse kupsinjika kwa kutentha, kumabweretsa ming'alu.

Zowonongeka: Mafuta, mafuta, kapena oxidation pamtunda angayambitse kusakanizika bwino ndi kusweka.

Zothetsera: Kuwongolera Kuyika kwa Kutentha: Gwiritsani ntchito njira monga kutsekemera kwa kutentha kuti muchepetse kulowetsa kutentha komanso kupewa kutenthedwa. Preheat gawo lapansi ngati kuli kofunikira kuti muchepetse kutenthedwa kwa kutentha.

Kuyeretsa Bwino Kwambiri: Onetsetsani kuti zonse zayeretsedwa bwino musanawotchere kuti muchotse zowononga.

3. Porosity

Vuto: Porosity imatanthawuza kukhalapo kwa matumba a mpweya mkati mwa weld, zomwe zimafooketsa mgwirizano ndipo zingayambitse kulephera msanga.

Zomwe Zimayambitsa: Kusatetezedwa Kokwanira: Kutetezedwa kosakwanira kuzinthu zam'mlengalenga panthawi ya kuwotcherera kumatha kuyambitsa mpweya.

Chinyezi mu Filler Material: Ngati chodzaza chimatenga chinyezi, chimatha kutulutsa mpweya panthawi yowotcherera.

Mayankho: Limbikitsani Chitetezo: Onetsetsani kuti mpweya wotchingira mpweya ukuyenda mokwanira komanso mosasinthasintha. Mu kuwotcherera kwa TIG, onetsetsani kuti kuphimba kwa gasi ndikokwanira kuteteza dziwe la weld.

Dry Filler Zida: Sungani zinthu zodzaza bwino kuti mupewe kuyamwa kwa chinyezi, ndikuzigwiritsa ntchito mukangotsegula.

4. Osauka Fusion

Vuto: Kuphatikizika koyipa kumachitika pamene nsonga ya tungsten carbide sigwirizana kwathunthu ndi gawo lapansi, zomwe zimapangitsa kuti mafupa azikhala ofooka.

Zomwe zimayambitsa: Njira Yowotcherera Molakwika: Kutentha kosakwanira kapena kona yowotcherera yolakwika kumatha kuletsa kuphatikizika koyenera.

Kusagwirizana kwa Zinthu: Kusiyana kwa ma coefficients owonjezera kutentha pakati pa zinthu kungayambitse kusamangirira kokwanira.

Mayankho: Sinthani Njira Zowotcherera: Yesani ndi liwiro lowotcherera, ngodya, ndi matenthedwe osiyanasiyana kuti muwonjezere kuphatikizika. Onetsetsani kuti njira yowotcherera imalola kusungunuka kokwanira kwa carbide ndi gawo lapansi.

Sankhani Zida Zogwirizana: Gwiritsani ntchito zida zoyatsira zomwe zimagwirizana ndi matenthedwe a tungsten carbide ndi zinthu zoyambira.

5. Kusokoneza Kwambiri

Vuto: Kupotoza kwambiri kumatha kuchitika panthawi yowotcherera, zomwe zimapangitsa kuti machekawo agwedezeke kapena kupotoza nsonga.

Zomwe zimayambitsa: Kutentha kosiyana: Kutentha kofulumira ndi kuziziritsa kungayambitse kutsika kofanana ndi kukulitsa.

Thandizo Losakwanira: Ngati chogwiritsira ntchito sichikuthandizidwa mokwanira, chimatha kusinthasintha panthawi yowotcherera.

Zothetsera: Kuwongolera Kutentha ndi Kuziziritsa: Gwiritsani ntchito njira zoziziritsira kale ndi zowongolera kuti muchepetse kutentha. Chithandizo cha kutentha pambuyo pa weld chingathandizenso kuchepetsa nkhawa.

Perekani Thandizo Lokwanira: Gwiritsani ntchito zomangira kapena jigs kuti mukhazikitse chogwirira ntchito panthawi yowotcherera, kuonetsetsa kuti chikugwirizana.

Mapeto

Kuthetsa zovuta zowotcherera wamba ndi maupangiri a tungsten carbide kumafuna kumvetsetsa bwino momwe kuwotcherera ndi zovuta zomwe zingachitike. Pozindikira zomwe zimayambitsa mavuto monga kusalowera kokwanira, kung'ambika, porosity, kusakanizika bwino, ndi kupotoza kwambiri, opanga amatha kugwiritsa ntchito njira zothetsera kuwongolera bwino kwa ma welds awo. Kuwunika kosalekeza ndikusintha magawo awotcherera, komanso kukonzekera mosamala ndi kuyeretsa, ndikofunikira kuti mukwaniritse bwino kwambiri zida za tungsten carbide. Pamene makampani azitsulo zolimba akukula, kukhalabe ndi miyezo yapamwamba muzowotcherera kudzakhalabe kofunika popanga zida zodalirika komanso zogwira mtima.
