Iimpawu zobugcisa ze-EM12K Submerged Arc Welding Wire

I-EM12K, ehambelana neenkcukacha ze-AWS A5.17, imele uhlobo oluthile lweucingo lokuwelda lwe-arc olungaphantsi komhlabaYenzelwe ukuhlanganiswa okuqinileyo kwezinto zentsimbi yekhabhoni. Njengento ebalulekileyo esetyenziswayo kwinkqubo yokuwelda i-arc engaphantsi komhlaba, ukusebenza kwayo kunxulunyaniswa nokusetyenziswa ngaxeshanye kwe-flux ehambelanayo. Le ntambo yokuwelda i-arc engaphantsi komhlaba yenzelwe ukuvelisa iidipozithi ze-weld ezihambelanayo nezisemgangathweni ophezulu ezikwaziyo ukumelana noxinzelelo olukhulu lokusebenza kwiindawo zoshishino ezifuna amandla.

Uphawu olucacileyo lwentambo yokuwelda ye-arc engaphantsi komhlaba ye-EM12K kukwakheka kwayo ngokweekhemikhali. Le ntambo inomxholo wekhabhoni ophezulu kakhulu xa ithelekiswa nezinye iiklasi ngaphakathi kohlu lwayo. Ixutywe ngeepesenti eziphezulu ze-manganese kunye ne-silicon, eyenzelwe ngokukodwa ukudlula amanqanaba afumaneka kwi-EL12 wire grade. Olu lungelelwaniso oluchanekileyo lwezinto ezisisiseko lubalulekile ekufezekiseni iipropati zoomatshini ezifunekayo kunye nokuziphatha kwe-metallurgical kwi-weld egqityiweyo.

Ukwanda kwamanqanaba e-manganese kunye ne-silicon kule ntambo yokuwelda kuyawuphucula kakhulu amandla ayo okususa i-oxidizing ngexesha lokusebenza kokuwelda. Olu luphawu olubalulekileyo lobuchwephesha, njengoko lulwa ngokukhutheleyo ukwakheka kwe-porosity ngokukhupha i-oksijini kwidama lokuwelda elinyibilikisiweyo. Ukusetyenziswa kwaleucingo lokuwelda lwe-arc olungaphantsi komhlabaikhuthaza ukuqina kwesinyithi esinyibilikisiweyo kunye nokuthembeka, okwenza ukuba ibe lukhetho oluthembekileyo kwizicelo apho ukuhlanganiswa okupheleleyo kunye needipozithi ezingenaziphene kuyimfuneko.

Isinyithi esifakwe kwi-weld esivela kwi-wire ye-EM12K sibonisa ulungelelwano olufanelekileyo lwamandla kunye nokuguquguquka, olufanele iinkqubo zokuwelda ezidlula ngeendlela ezininzi. Oku kuyenza ibe yeyona ifanelekileyo yokusetyenziswa xa kusenziwa izakhiwo ezinzima, iinqanawa zoxinzelelo, iinqanawa zeenqanawa, kunye nezinto ezakhiweyo ezithwalwa yimithwalo ephezulu. Ukusebenza kwayo rhoqo kuqinisekisa ukuba amalungu afakwe kwi-weld agcina ukuthembeka kwawo ixesha elide, nokuba phantsi kweemeko ezinzima zenkonzo ezibandakanya ukungcangcazela okanye uxinzelelo.

I-EM12Kucingo lokuwelda lwe-arc olungaphantsi komhlabayi-engineering ekhethekileyo esetyenziswayo kwizicelo ezibalulekileyo ze-carbon steel. Iprofayili yayo eyahlukileyo yekhemikhali, ebonakaliswa yi-carbon ephezulu, i-manganese, kunye ne-silicon, ibonelela nge-deoxidation ephuculweyo kunye neempawu zoomatshini ezinokuthenjwa kwimeko edibeneyo. Ukunamathela kumgangatho we-AWS A5.17 kuqinisekisa umgangatho wayo ohambelanayo, nto leyo eyenza olu cingo lube sisisombululo esifanelekileyo kumashishini afuna uqhagamshelo oluqinileyo nolusebenza kakuhle.
