Waya wowotcherera wosamva kuvala
Flux-cored waya imadziwikanso kuti waya wopangidwa ndi ufa, waya wa tubular, imatha kugawidwa m'magulu awiri achitetezo cha gasi komanso chitetezo chosagwiritsa ntchito gasi.Pamwamba pa waya wa flux-cored amapangidwa ndi chitsulo chochepa cha carbon kapena chitsulo chochepa cha alloy chokhala ndi pulasitiki wabwino.Njira yopangira ndi yakuti chitsulocho chimakulungidwa mu mawonekedwe a gawo la U, ndiyeno ufa wowotcherera umadzazidwa mu mzere wachitsulo wopangidwa ndi U malinga ndi mlingo, ndipo mzere wachitsulo umakulungidwa mwamphamvu ndi mphero yokakamiza, ndipo pamapeto pake amakokedwa. mumitundu yosiyanasiyana ya waya wa flux-cored.Pazonse, mawaya a flux-cored amatha kugawidwa kukhala mawaya odziteteza okha ndi waya wotetezedwa ndi gasi.Waya wotetezedwa ndi gasi nthawi zambiri amagawidwa m'magulu awiri a slag, omwe ndi acidic ndi maziko (T 1 ndi T 5).Waya wa acid slag flux-cored umagwira ntchito bwino ndipo utha kugwiritsidwa ntchito powotcherera pamalo onse.Ndizinthu zomwe zimagwiritsidwa ntchito kwambiri pakuwotcherera kwapamwamba kwambiri pamafakitale omanga zombo.Chitsulo chowotcherera cha waya woyambira wozungulira chimakhala ndi mphamvu yoyeretsa, ndipo chimatha kupeza njira yabwino kwambiri posintha njira yoyenera, yomwe ili yoyenera malo owotcherera lathyathyathya ndi kuwotcherera fillet.
