I-arc welding engaphansi kwamanzi (SAW) kuyinqubo evamile yokushisela i-arc.I-patent yokuqala yenqubo ye-submerged-arc welding (SAW) yakhishwa ngo-1935 futhi yamboza i-arc kagesi ngaphansi kombhede we-flux granulated.Eyathuthukiswa ekuqaleni futhi inelungelo lobunikazi nguJones, uKennedy kanye noRothermund, le nqubo idinga i-electrode eqinile esetshenziswayo esetshenziswayo eqhubekayo noma eyishubhu (yensimbi enensimbi).I-molten weld kanye ne-arc zone ivikelekile ekungcoleni komoya "ngokucwiliswa" ngaphansi kwengubo ye-granular fusible flux ehlanganisa i-lime, i-silica, i-manganese oxide, i-calcium fluoride, nezinye izinhlanganisela.Lapho kuncibilika, i-flux iba conductive, futhi inikeza indlela yamanje phakathi kwe-electrode nomsebenzi.Lolu ungqimba oluwugqinsi lokuguquguquka lumboza ngokuphelele insimbi encibilikisiwe ngaleyo ndlela luvimbele isipatha nezinhlansi kanye nokucindezela imisebe eshubile ye-ultraviolet kanye nentuthu eyingxenye yenqubo yokushisela i-arc metal evikelekile (SMAW).

I-SAW ivamise ukusetshenziswa ngemodi ezenzakalelayo noma eyenziwe ngomshini, nokho, izibhamu ze-SAW ezizenzakalelayo (ezibanjwa ngesandla) ezinengcindezi noma amandla adonsela phansi okuphakelayo ziyatholakala.Inqubo ivamise ukukhawulelwa ezindaweni zokushisela eziyisicaba noma ezivundlile (nakuba ukushisela kwendawo yegroove evundlile kwenziwe ngohlelo olukhethekile lokusekela ukuguquguquka).Amazinga okubekwa asondela ku-45 kg/h (100 lb/h) abikiwe-lokhu kuqhathaniswa ne-~5 kg/h (10 lb/h) (ubukhulu) bokushisela i-arc yensimbi evikelekile.Nakuba ama-currents asukela ku-300 kuya ku-2000 A evame ukusetshenziswa, ama-currents afika ku-5000 A nawo asetshenzisiwe (ama-arcs amaningi).

Ukuhluka kwentambo ye-electrode eyodwa noma eziningi (2 kuya ku-5) zenqubo zikhona.I-SAW strip-cladding isebenzisa i-electrode eyisicaba (isb. 60 mm ububanzi x 0.5 mm ubukhulu).Amandla e-DC noma e-AC angasetshenziswa, futhi izinhlanganisela ze-DC ne-AC zivamile ezinhlelweni eziningi zama-electrode.Amandla we-voltage welding welding asetshenziswa kakhulu;nokho, amasistimu amanje angaguquki ahlanganiswe ne-voltage sensing wire-feeder ayatholakala.
