Iingcebiso Indlela yokwahlula i-welding slag kunye nentsimbi etyhidiweyo ngexesha le-welding

Okokuqala, i-welding slag yimveliso yokunyibilika kwe-electrode coating kunye ne-high-temperature metallurgical reaction of the weld. I-slag ye-welding yenziwa ikakhulu ngee-oxide zetsimbi okanye ii-oxide ezingezizo ezentsimbi kunye nezinye iityuwa zamaminerali. Ekubeni ukuxinana kwayo kuncinci kakhulu kunoko kwentsimbi engamanzi ngexesha le-welding, i-welder inokubona ngokulula umaleko wezinto ezidadayo kwindawo ephezulu yedama elityhidiweyo ngexesha lenkqubo ye-welding. Ngokumalunga nombala, imnyama kunentsimbi engamanzi echibini elityhidiweyo, kwaye iqukuqela kwicala elichaseneyo necala le-welding kwaye kumacala omabini angasemva, kwaye iphole njengoko i-welding iqhubeka iba yi-welding slag.

Okwesibini, i-welding slag idlala indima enkulu ekukhuseleni i-weld bead ngexesha lenkqubo ye-welding. I-slag igubungele isinyithi solwelo kwidama elityhidiweyo ukuze sahlule isinyithi esilulwelo emoyeni, sithintela ukungena kweegesi ezinobungozi ezifana neoksijini, i-nitrogen, kunye ne-hydrogen emoyeni, ngaloo ndlela ikhusela i-weld bead. Ke ngoko, ngexesha lenkqubo ye-welding, kufuneka ubeke ingqalelo kwi-angle ye-welding ukuqinisekisa ukuba i-welding slag igeleza ngasemva kunye namacala omabini angasemva, ukuze uqwalasele ukubunjwa kwe-weld, ugweme isizukulwana seziphene ezifana ne-slag. ukufakwa kunye neepores, kwaye uqinisekise umgangatho welding. Okwesithathu, ngokutsho kwe-welder enamava kwisiza, ukuba ufuna ukuchonga intsimbi etyhidiweyo ngexesha le-welding, kufuneka uqaphele kuphela kwaye uya kufumanisa ukuba i-welding slag edadayo kwintsimbi yolwelo ifana neoli emanzini, edada phezu kwamanzi. ichibi elityhidiweyo, ekulula kakhulu ukulichonga.
