Oomatshini bokuwelda bamabala aphakathi basetyenziswa kakhulu kwimizi-mveliso.Ukuqulunqwa kwedama elityhidiweyo ngexesha le-welding yinkqubo ebalulekileyo emisela umgangatho we-weld.Kweli nqaku, siza kuxoxa ngenkqubo yokwenziwa kwechibi elityhidiweyo kumatshini wokuwelda amabala aphakathi.
Okokuqala, i-welding current isetyenziswe kwii-electrodes ezimbini, ezivelisa ubushushu obukhulu kwindawo yoqhagamshelwano phakathi kwe-electrodes kunye ne-workpiece.Oku kubangela ukuba ubushushu bentsimbi bunyuke ngokukhawuleza, kubangele ukubunjwa kwedama elincinci elityhidiweyo.
Njengoko i-welding current iqhubeka ihamba, idama elityhidiweyo liya likhula ngokunzulu, kwaye isinyithi esikufuphi nedama siqala ukuthamba.Isinyithi esithambileyo sihamba sisiya kwidama elinyibilikisiweyo ngenxa yesenzo se-capillary, esikhokelela ekuyilweni kwe-nugget eqinileyo.
Ngexesha lenkqubo ye-welding, ubushushu be-pool etyhidiweyo bubalulekile ekufezekiseni i-weld efanelekileyo.Ukuba iqondo lokushisa liphantsi kakhulu, i-nugget ayinakwenzeka ngokufanelekileyo, ekhokelela kwi-welds ebuthakathaka.Ukuba iqondo lokushisa liphezulu kakhulu, isinyithi sinokugqithiswa kwaye sibangele iziphene kwi-weld.
Ukuqinisekisa umgangatho we-weld, kubalulekile ukulawula iiparitha ze-welding ezifana ne-welding current, ixesha le-welding, kunye ne-electrode force.Ngokulungelelanisa ezi parameters, ukushisa kwechibi elityhidiweyo kunokulawulwa, okubangela i-weld eqinile kwaye ethembekileyo.
Ukuqukumbela, inkqubo yokwenziwa kwechibi elinyibilikisiweyo kumatshini wokuwelda amaza aphakathi yinkqubo entsonkothileyo efuna ulawulo olululo lweeparamitha zokuwelda.Ngokuqonda inkqubo, sinokuqinisekisa umgangatho we-weld kunye nokuphucula ukusebenza kakuhle kwenkqubo ye-welding.
