Uyazi ukuthi zingaki izigaba ezibandakanyekayo kwinqubo yokushisela yemishini yokushisela imvamisa emaphakathi? Namuhla, umhleli uzokunikeza isingeniso esiningiliziwe senqubo yokushisela yomshini wokushisela amabala aphakathi nendawo. Ngemva kokudlula kulezi zigaba ezimbalwa, umjikelezo wokushisela womshini wokushisela amabala aphakathi nendawo.
1. Yenza ukulayisha kuqala kwengcindezi ngaphambi kokuvula amandla.
Inhloso yenkathi yokulayisha kuqala iwukuthintana eduze phakathi kwezingxenye ezishiselwe, okubangela ukuwohloka kwepulasitiki kwezingxenye eziphumela endaweni yokuxhumana, kulimaze ifilimu ye-oxide ebusweni, nokukhiqiza ukumelana nokuxhumana okuzinzile. Uma ingcindezi iphansi kakhulu, izingxenye ezimbalwa kuphela eziphumela ngaphandle zingathintana, zenze ukumelana nokuxhumana okukhulu. Kusukela kulokhu, insimbi izoncibilika ngokushesha endaweni yokuxhumana, iqhume ngendlela yezinhlansi, futhi ezimweni ezinzima, ingxenye ehlanganisiwe noma i-electrode ingase ishiswe. Ngenxa yokuqina nokuqina kwesakhiwo okuphezulu kwezingxenye ezishiselwe, ikhwalithi ephezulu yezingxenye ezishiselwe impofu. Ngakho-ke, ukuze wenze izingxenye ezihlanganisiwe zithintane eduze futhi uzinzise ukumelana kwendawo yokuthungatha, okwamanje okungeziwe kungandiswa ngesikhathi sesiteji sokucindezela kwangaphambili noma ngesikhathi sokucindezela kwangaphambili. Ngalesi sikhathi, ingcindezi yangaphambi kokucindezela ngokuvamile iphindwe izikhathi ezingu-0.5-1.5 ingcindezi evamile, kanti okwamanje eyengeziwe ingu-1/4-12 we-welding current.
2. Ukwenza ukufudumeza kukagesi.
Ngemuva kokucindezela kwangaphambili, izingxenye ezishiselwe zingahlanganiswa ngokuqinile. Lapho imingcele yokushisela ilungile, insimbi ihlala iqala ukuncibilika endaweni yokuxhumana phakathi kwezingxenye ezimbili ezishiselwe endaweni ye-electrode clamping, ngaphandle kokukhula, kancane kancane yakha i-nucleus encibilikisiwe. Ngaphansi kwengcindezi ngesikhathi sokushisela, i-nucleus encibilikisiwe icwebezela (ngesikhathi sokushisela), yakha isibopho esiqinile phakathi kwezingxenye ezimbili ezishiselwe.
3. Ukufosha nokucindezela.
Lesi sigaba saziwa nangokuthi isiteji sokupholisa icrystallization, okusho ukuthi ngemva kokuba inkaba encibilikisiwe ifinyelela umumo nosayizi ofanele, i-welding current iyanqanyulwa, kanti umgogodla oncibilikisiwe uyaphola futhi ucwebezele ngaphansi kwengcindezi. I-crystallization ewumongo oncibilikisiwe yenzeka kufilimu yensimbi evaliwe futhi ayikwazi isivumelwano ngokukhululekile ngesikhathi sokucwebezela. Ngokusebenzisa le ndlela, izinsimbi ezicwebezelayo zingahlanganiswa ndawonye ngokuqinile ngaphandle kokushwabana noma ukuqhekeka, okuvumela insimbi encibilikisiwe ukuba icwebezele ngokuphelele ngaphambi kokuyeka ukusetshenziswa.
