Ukuweldai-electrode iquka iinxalenye ezimbini, i-core kunye ne-coating.I-Metal core welding electrode ingaphandle kwepeyinti (i-coating) yoxinzelelo olufanayo olufakwe kwi-solder core ngononophelo.Iindidi ezahlukeneyo ze-welding, i-welding core iyahluka.Ukuwelda i-electrode core metal core, ukuze kuqinisekiswe umgangatho kunye nokusebenza kwe-weld, i-butt umxholo ongundoqo wento yentsimbi inemithetho engqongqo, ngakumbi kumxholo wokungcola okuyingozi (okufana nesulfure, i-phosphorus, njl.), kufuneka yizithintelo ezingqongqo kunezinto ezisisiseko.Ingxowa yeyeza ye-Electrode yayibizwa ngokuba yiweld metal core coated core.I-Welding core wire inobude obuthile kunye nedayamitha.Xa i-soldering, i-welding core ineempembelelo ezimbini: Okokuqala, ukuqhuba i-welding yangoku, amandla e-arc aguqulwa abe bubushushu, i-wire core yesibini ngokwayo isetyenziswe njengentsimbi yokuzalisa kunye nolwelo olutyhidiweyo lwe-metal fusion weld lwenziwa.

Uxinzelelo olufakwe kumphezulu wengubo ebizwa ngokuba yi-core solder coating.I-Electrode coating idlala indima ebaluleke kakhulu kwinkqubo ye-welding.Ukusetyenziswa kwewelding ye-electrode yesikhumba engenaso iziyobisi, inkqubo yokuwelda, ioksijini kunye nenitrogen emoyeni iya kuba kukungena okukhulu kwesinyithi esinyibilikisiweyo, isinyithi sesinyithi kunye nezinto eziluncedo kwikhabhoni, isilicon, imanganese oxide kunye nokwakheka kwenitride yeeoxide ezahlukeneyo kunye i-nitrides, kwaye ihlala kwi-weld, i-weld slag, okanye ibangele iintanda.Ukunyibilika kwi-puddle yerhasi kunokubangela inani elikhulu le-weld porosity, ezi zinto zinokwenza iimpawu zomatshini we-weld (amandla, ixabiso lempembelelo, njl. njl.) zincitshiswe kakhulu, ngelixa i-weld brittle.

I-SMAW welding electrode esetyenziswa ngokutyabeka kunye ne-welding core eyenziwe ngamacandelo amabini.Xa i-welding, i-electrode ye-welding njengesandla esinye, kunye ne-pilot arc current conduction effect, ukwenzela ukuba phakathi kwee-electrode kunye nesiseko sesinyithi kwi-arc eqhubekayo, ezinzileyo, ukubonelela ubushushu obuyimfuneko ukuze kunyibilike i-solder.Ngakolunye uhlangothi, kwaye njengentsimbi yokuzalisa i-welding yongezwa kwi-weld ukuba ibe yinto ephambili ye-weld metal.Ngako oko, ukubunjwa komgangatho we-welding kunye ne-welding, i-chemical composition of the weld metal ichaphazela ngokuthe ngqo iipropathi zoomatshini kunye neempawu zomzimba.Ukongezelela, i-electrode nayo inempembelelo enkulu ekuzinzeni komgangatho wembonakalo ye-weld, inkqubo ye-welding efana nemveliso ye-welding.
