Zofanana ndi kuwotcherera kukana, kukaniza brazing kumagwiritsa ntchito kutentha kuzinthu zomangira zokhala ndi magetsi apamwamba kwambiri.Monga momwe dzina lake likusonyezera, ndondomekoyi imagwiritsa ntchito mfundo yotsutsa kupanga kutentha kofunikira pa ntchito zake;monga magetsi akuyenda mudera lomwe limaphatikizapo chogwirira ntchito, kukana kwa dera kumatulutsa kutentha.
Monga kuwotcherera kukana ndi njira zina zowotcherera, kukaniza brazing kumafuna zida zapadera - nthawi zambiri thiransifoma, maelekitirodi, ndi gwero lamphamvu.Kusiyanitsa kwake kwakukulu ndikuti kumaphatikizapo kugwiritsa ntchito zida zowonjezera zowonjezera kuti zilumikize mbali zonse pamodzi.
A resistance brazing operation nthawi zambiri amakhala ndi magawo awa:
1. Kukonzekera zigawo zonse, kuphatikizapo maelekitirodi, kuchotsa zowonongeka pamtunda.
2. Kukonza zigawo zonse mu msonkhano.
3. Kukhazikitsa dera lomwe limaphatikizapo workpiece.
4. Kuyika zinthu zodzaza (nthawi zambiri zimapangidwira kapena zojambulazo) pakati pa malo olowa.
5. Kuthamanga pakali pano kudutsa dera kuti apange kutentha koyenera kusungunula zinthu zodzaza ndi kupanga mgwirizano wazitsulo pakati pa magawo.
6. Kutembenuza mphamvu yamagetsi ndikusunga kupanikizika kuti zinthu za braze zikhazikike ndikupanga mgwirizano wolimba pakati pa zigawo ziwirizi.
7. Kuchotsa chophatikizira chomalizidwa pachokhacho ndikuchotsa kusuntha kulikonse.
8. Kuyang'ana mgwirizano womalizidwa.
Poyerekeza ndi njira zina zowotcherera, kukana brazing kumapereka maubwino angapo.Mwachitsanzo, mosiyana ndi kuwotcherera kwachikhalidwe, kukaniza brazing kumapereka izi:
● Kutentha kwambiri kuti agwirizane ndi zitsulo, monga mkuwa kapena mkuwa, zomwe sizikanatha kulumikizana.
● Kugwira ntchito kosavuta monga kutchingira kukaniza kumangofunika kubweretsa zodzaza kuti zisungunuke, osati zopangira zokha.
● Kutentha kwapadera komweko, kuonetsetsa kuti mbali zina za workpiece zikhale zotetezedwa ndikukhalabe ndi mphamvu.
● Kutsika mtengo kwa ndalama chifukwa zipangizo zofunika ndi zotsika mtengo.
● Kunyamula kwambiri n'kothandiza pokonza zida zazikulu zomwe sizinganyamulidwe mosavuta.
Ngakhale kukana brazing kumapereka zabwino zambiri, sikungakhale chisankho choyenera pakugwiritsa ntchito kulikonse.Chifukwa chogwiritsa ntchito kutentha komweko, zogwirira ntchito zimatha kusokonekera.Zida zopangira brazing zimafunikanso kukhala ndi malo otsika osungunuka, chifukwa chogwirira ntchitocho chimapangidwa ndi zinthu zochititsa chidwi kwambiri.Kuonjezera apo, ndondomekoyi si yabwino kumadera akuluakulu olowa;ndizothandiza kwambiri kuti zigwiritsidwe ntchito pamfundo zing'onozing'ono.
Ngakhale sizowoneka bwino muzochitika zilizonse, kukana brazing kumapindulitsa ntchito zambiri zopanga chifukwa cha:
● Kukhoza kupanga zomangira zokhazikika pakati pa zipangizo zapansi.
● Ndalama zogulira misonkhano yachigawo yosavuta komanso yovuta.
● Kutsika kwa kutentha ndi kugawa kwambiri ngakhale kutentha poyerekeza ndi kuwotcherera.
● Kuchita bwino pophatikiza zitsulo zopyapyala ndi zokhuthala.
● Kutha kupirira molimba mtima.
