Icingo lokuwelda elinoboya obukwaziyo ukunxitywa
I-Flux-core wire yaziwa ngokuba yi-powder-core wire, ucingo lwe-tubular, lunokwahlulwa lube ngamacandelo amabini okukhusela igesi kunye nokukhuselwa kwegesi.Umphezulu we-flux-core wire yenziwe nge-carbon steel low okanye i-alloy iron ephantsi kunye neplastiki efanelekileyo.Indlela yokuvelisa kukuba umgca wensimbi ugqitywe kwi-U-shaped section shape, emva koko i-powder ye-welding izaliswe kwi-strip yensimbi efana ne-U ngokomlinganiselo, kwaye umgca wensimbi ugqitywe ngokuqinileyo ngokusila, kwaye ekugqibeleni utsalwe. kwiinkcukacha ezahlukeneyo zocingo olunamanzi.Lilonke, ucingo olune-flux-cored lunokwahlulwa lube lucingo oluzikhuselayo oluzikhuselweyo kunye nocingo olukhuselwe yigesi olune-cored.I-Gas shielded flux-coreed wire idla ngokuhlulahlula kwiinkqubo ezimbini ze-slag, ezizezi, i-acidic kunye nesiseko (T 1 kunye ne-T 5).I-asidi ye-slag flux-coreed wire inokusebenza kakuhle kwaye ingasetyenziswa kwi-welding yonke indawo.Yeyona nto isetyenziswa ngokubanzi i-welding ephezulu esebenzayo kwishishini lokwakha iinqanawa.Intsimbi ye-weld yocingo olusisiseko lwe-flux-cored inesiphumo esihle sokuhlanjululwa, kwaye inokufumana ukusebenza kwenkqubo egqwesileyo ngokuhlengahlengisa ifomyula efanelekileyo, efanelekileyo kwindawo ye-flat welding kunye ne-fillet welding.
