Ukuwelda kwe-arc emanzini (SAW) yinkqubo ye-arc welding eqhelekileyo.Ilungelo elilodwa lomenzi wechiza kwinkqubo ye-submerged-arc welding (SAW) yakhutshwa ngo-1935 kwaye yagquma i-arc yombane phantsi kwebhedi ye-granulated flux.Ekuqaleni iphuhliswe kwaye inelungelo lobunikazi nguJones, uKennedy kunye noRothermund, inkqubo ifuna i-electrode eyondliwe ngokuqhubekayo eqinileyo okanye i-tubular (i-metal cored).I-weld etyhidiweyo kunye ne-arc zone ikhuselwe kungcoliseko lwe-atmospheric ngokuthi "ifakwe emanzini" phantsi kwengubo ye-granular fusible flux equka i-lime, i-silica, i-manganese oxide, i-calcium fluoride, kunye nezinye iikhompawundi.Xa ityhidiwe, i-flux iba conductive, kwaye inika indlela yangoku phakathi kwe-electrode kunye nomsebenzi.Lo maleko ngqindilili wokuguquguquka ugubungela ngokupheleleyo isinyithi esinyibilikisiweyo ngaloo ndlela uthintela isitshizi kunye neentlantsi kunye nokucinezela imitha yeultraviolet enzulu kunye nomsi oyinxalenye yenkqubo yentsimbi ekhuselweyo ye-arc welding (SMAW).

I-SAW idla ngokusebenza kwimo ezenzekelayo okanye yomatshini, nangona kunjalo, i-semi-automatic (ebanjwe ngesandla) i-SAW guns enoxinzelelo okanye ukuhanjiswa kwe-gravity flux feed iyafumaneka.Inkqubo ngokuqhelekileyo inqunyelwe kwi-flat okanye i-horizontal-fillet-welding positions (nangona i-horizontal groove position welds yenziwe ngelungiselelo elikhethekileyo lokuxhasa ukuguquka).Amazinga okubeka asondela kwi-45 kg / h (100 lb / h) axeliwe-oku kuthelekisa ne ~ 5 kg/h (10 lb/h) (max) ye-shielded metal arc welding.Nangona imisinga ukusuka kwi-300 ukuya kwi-2000 A iqhele ukusetyenziswa, iicurrents ezifikelela kwi-5000 A nazo zisetyenzisiwe (ii-arcs ezininzi).

I-single okanye i-multiple (2 ukuya kwi-5) iinguqu ze-electrode zenkqubo zikhona.I-SAW strip-cladding isebenzisa i-electrode yomgca osicaba (umz. 60 mm ububanzi x 0.5 mm ubukhulu).I-DC okanye amandla e-AC anokusetyenziswa, kwaye indibaniselwano ye-DC kunye ne-AC ixhaphake kwiinkqubo ezininzi ze-electrode.Amandla ombane we-welding welding asetyenziswa rhoqo;nangona kunjalo, iinkqubo zangoku eziqhubekayo ngokudibanisa ne-voltage sensing wire-feeder ziyafumaneka.
