Ii-electrodes ze-Welding ziingcingo zetsimbi ezibhaka kwiingubo zeekhemikhali.Intonga isetyenziselwa ukugcina i-arc ye-welding kunye nokubonelela ngentsimbi yokuzalisa efunekayo ukuze ukudibanisa kuhlanganiswe.Ingubo ikhusela isinyithi emonakalweni, izinzile i-arc, kwaye iphucula i-weld.Ububanzi bocingo, ngaphantsi kwengubo, bumisela ubungakanani bentonga ye-welding.Oku kubonakaliswa ngamaqhezu e-intshi afana no-3/32″, 1/8″, okanye 5/32.”I-diameter encinci ithetha ukuba ifuna i-current encinci kwaye ibeka ixabiso elincinci lokuzalisa isinyithi.
Uhlobo lwesiseko sesinyithi esidityanisiweyo, inkqubo ye-welding kunye nomatshini, kunye nezinye iimeko zimisela uhlobo lwe-electrode ye-welding esetyenzisiweyo.Ngokomzekelo, i-carbon ephantsi okanye "intsimbi epholileyo" idinga intonga yentsimbi yentsimbi.I-welding cast iron, i-aluminiyam okanye ubhedu idinga iintonga ezahlukeneyo ze-welding kunye nezixhobo.
I-flux coating kwi-electrodes inquma indlela eya kwenza ngayo ngexesha lenkqubo ye-welding.Ezinye zezinto zokwaleka ziyatsha kunye ne-flux etshileyo yenza umsi kwaye isebenze njengekhaka elijikeleze i-welding "pool," ukuyikhusela kumoya oyijikelezileyo.Inxalenye ye-flux iyanyibilika kwaye ixube kunye nocingo kwaye emva koko idada ukungcola phezulu.Oku kungcola kwaziwa ngokuba yi "slag".I-weld egqityiweyo iya kuba brittle kwaye ibe buthathaka ukuba ayikho ngenxa ye-flux.Xa umdibaniso odibeneyo upholile, i-slag inokususwa.Ihamile kunye nebrashi yocingo zisetyenziselwa ukucoca kunye nokuvavanya i-weld.
I-electrode ye-metal-arc welding inokuthi ihlelwe njenge-electrode engenanto, i-electrode egqunywe ukukhanya, kunye ne-arc ekhuselweyo okanye i-electrodes enzima.Uhlobo olusetyenzisiweyo luxhomekeke kwiimpawu ezithile ezifunekayo ezibandakanya: ukuxhathisa ukubola, i-ductility, amandla aphakamileyo aphezulu, uhlobo lwesiseko sesinyithi esiza kuxutywa;kunye nokuma kweweld ukuba mcaba, ithe tyaba, ime nkqo, okanye ngaphezulu.
