Hlela
Ngokweendlela zokuvelisa, iibhobho zetsimbi zinokuhlulwa zibe ngamacandelo amabini: imibhobho yentsimbi engenamthungo kunye nemibhobho yentsimbi edityanisiweyo.imibhobho yentsimbi edityanisiweyo kubhekiselwa kuyo njengemibhobho edityanisiweyo ngokufutshane.
Imibhobho yentsimbi engenamthungo inokohlulwa ibe yimibhobho eshushu esongwayo engenamthungo, imibhobho etsalwa ngokubanda, imibhobho yentsimbi echanekileyo, imibhobho eshushu eyandisiweyo, imibhobho esontiweyo ebandayo, kunye nemibhobho ekhutshiweyo ngokweendlela zokuvelisa.
Imibhobho yentsimbi engenamthungo yenziwe ngentsimbi yekhabhoni ekumgangatho ophezulu okanye intsimbi yealloyi, kwaye inokuba shushu iqengqeleke okanye iqengqeleke ebandayo (itsalwa).
Imibhobho yentsimbi edityanisiweyo yohlulwe ibe yimibhobho edityanisiweyo yomlilo, imibhobho yombane (i-resistance welding) kunye nemibhobho edityanisiweyo yearc ezenzekelayo ngenxa yeenkqubo zabo zokuwelda ezahlukeneyo.Ngenxa yeendlela ezahlukeneyo zokuwelda, zahlulwe zaba yimibhobho edityanisiweyo ethe tye kunye nemibhobho edityanisiweyo.Ngenxa yeemilo zabo zokuphela, ziphinde zohlulwe zibe yimibhobho edityanisiweyo ejikelezayo kunye nemibhobho edityanisiweyo ekhethekileyo (isikwere, isicaba, njl. njl.).
Imibhobho yentsimbi edityanisiweyo yenziwa ngokudityaniswa kweepleyiti zentsimbi ezigalelwe kwiimilo ze-tubular ezine-butt okanye i-spiral seams.Ngokweendlela zokuvelisa, zahlulwa kwakhona zaba yimibhobho yentsimbi edityanisiweyo yokuthutha ulwelo olunoxinzelelo oluphantsi, imibhobho yentsimbi edityanisiweyo, imibhobho yentsimbi eqengqelekayo, kunye nemibhobho edityaniswe ngombane.Imibhobho yentsimbi engenamthungo ingasetyenziswa kumashishini ahlukeneyo afana nemibhobho yerhasi elulwelo kunye nemibhobho yegesi.Imibhobho edibeneyo ingasetyenziselwa imibhobho yamanzi, iipayipi zegesi, iipayipi zokufudumeza, iipayipi zombane, njl.
