Zvakafanana nekurwisa welding, resistance brazing inoshandisa kupisa kune bond zvinhu zvine high magetsi conductivity.Sezvinoratidzwa nezita rayo, iyo nzira inoshandisa musimboti wekupikisa kuburitsa kupisa kunodiwa pakuita kwayo;sezvo magetsi emagetsi anoyerera kuburikidza nedunhu rinosanganisira workpiece, kupikisa kwedunhu kunobudisa kupisa.
Kufanana nekudzivirira welding uye dzimwe nzira dzekushongedza, kuramba brazing kunoda hunyanzvi hwekushandisa-kazhinji transformer, electrodes, uye sosi yekumanikidza.Musiyano waro wakakosha ndewekuti unosanganisira kushandiswa kweimwe brazing zvinhu kubatanidza zvikamu pamwechete.
A resistance brazing operation inowanzobatanidza matanho anotevera:
1. Kugadzirira zvikamu zvose, kusanganisira electrodes, kubvisa tsvina yepamusoro.
2. Kugadzirisa zvikamu zvose mumusangano.
3. Kugadzira dunhu rinosanganisira workpiece.
4. Kuisa zvinhu zvekuzadza (kazhinji mu-pre-formed kana foil) pakati pezviso zvekubatana.
5. Kumhanya ikozvino kuburikidza nedunhu kuburitsa kupisa kunodiwa kunyungudutsa zvinhu zvekuzadza uye kugadzira chisungo chemetallurgical pakati pe substrates.
6. Kushandura magetsi emagetsi uye kuchengetedza kudzvinyirira kubvumira zvinhu zvebraze kuti zviome uye zvigadzire kubatana kwakasimba pakati pezvikamu zviviri.
7. Kubvisa mubatanidzwa wakapedzwa kubva pachigadziko uye kubvisa chero yakasara flux.
8. Kuongorora mubatanidzwa wakapedzwa.
Kuenzaniswa nedzimwe nzira dzekushongedza, kuramba brazing kunopa akati wandei mabhenefiti.Semuenzaniso, mukusiyana neyakajairwa nzvimbo welding, resistance brazing inopa zvinotevera:
● Tembiricha yakakwira kuti ibatanidze simbi dzinoshandiswa, dzakadai semhangura kana ndarira, dzaisagona kubatanidzwa neimwe nzira.
● Mashandiro ari nyore sezvo simbi inodzivirira inongoda chete kuunza iyo yekuzadza zvinhu pakunyungudika kwayo, kwete iyo workpiece pachayo.
● Kuwedzera kupisa kwenzvimbo, kuve nechokwadi kuti zvimwe zvikamu zvechishandiso zvinoramba zvakachengetedzwa uye kuchengetedza simba razvo.
● Mutengo wekudyara wakaderera sezvo mudziyo unodiwa usingadhure.
● Kutakurika kukuru kunobatsira pakugadzira michina mikuru isingatakurwe nyore nyore.
Nepo kuramba brazing ichipa akawanda mabhenefiti, inogona kunge isiri iyo sarudzo chaiyo kune yega application.Nekuda kwekushandiswa kwekudziya kwenzvimbo, workpieces inogona kukanganisa.Zvishandiso zveBrazing zvinodawo kuve nemapoinzi ekunyungudika, sezvo workpiece inogadzirwa nezvinhu zvinoitisa zvakanyanya.Uyezve, nzira yacho haina kunaka kune nzvimbo huru dzakabatana;inonyanya kushandiswa kushandiswa pamajoini maduku.
Kunyange zvisina kunaka mune ese mamiriro, kuramba brazing inobatsira akawanda ekugadzira maapplication nekuda kwayo:
● Kukwanisa kuumba zvisungo zvechigarire pakati pezvinhu zvepasi.
● Mari inodhura yemagungano ari nyore uye akaoma kunzwisisa.
● Kudzikira tembiricha uye kunyanya kupisa kugovera kana ichienzaniswa newelding.
● Kubudirira mukubatanidza simbi dzakatetepa uye dzakakora.
● Kukwanisa kuchengetedza zvakasimba dimensional kushivirira.
