Kwicandelo lokuwelda kwezakhiwo nezemizi-mveliso, ukukhethwa kwezinto ezifanelekileyo zokuzalisa kubalulekile ukuqinisekisa ukuthembeka nokusebenza kakuhle kwamalungu.I-Electrode yokuWelda yentsimbi yeCarbonudidi lubalulekile, luquka iintlobo ezahlukeneyo ezenzelwe ukuhlangabezana neemfuno ezithile zoomatshini nezenkqubo. Phakathi kwezi, i-AWS E7015, ekwabizwa ngokuba yimodeli 507 kwezinye iindawo, imele i-electrode esetyenziswa kakhulu ene-hydrogen ephantsi kwizicelo ezibalulekileyo zentsimbi yekhabhoni.
Uphawu oluphambili lwale Carbon Steel Welding Electrode yi-hydrogen sodium coating yayo ephantsi. Olu hlobo lokufaka lubalulekile ekunciphiseni ukungena kwe-hydrogen kwisinyithi se-weld, nto leyo enciphisa kakhulu umngcipheko wokuqhekeka okubangelwa yi-hydrogen, ingakumbi kwiindawo ezityebileyo okanye phantsi kweemeko ezixinzelelweyo. Isinyithi esigciniweyo sibonisa ukuqina okugqwesileyo, ukuqina, kunye nokumelana nokuqhekeka ngokubanzi, okwenza ukuba ifaneleke kwiindawo ezifuna kakhulu apho ukuthembeka kwesakhiwo kubaluleke kakhulu.
Ngokwembono yokusebenza, okuI-Electrode yokuWelda yentsimbi yeCarbonifuna ukusetyenziswa kwe-Direct Current Electrode Positive (DCEP) polarity. Olu phawu lombane lubonelela ngokungena nzulu kunye ne-arc ezinzileyo. Okuphawulekayo kukuba, i-electrode yenzelwe ukuwelda kwindawo yonke, inikezela ngokuguquguquka kwizicelo ezithe tyaba, ezithe tye, ezithe nkqo, kunye nezingaphezulu. Oku kuyenza ibe sisixhobo esibalulekileyo sokwenza izinto ezintsonkothileyo kunye nokwakhiwa kwentsimi apho ukuqhelaniswa kwe-weld kwahluka khona.
Ububanzi bokusetyenziswa kwale Electrode yeCarbon Steel Welding ene-hydrogen ephantsi buchazwe kakuhle. Icetyiswa kakhulu ekudibaniseni iintsimbi zekhabhoni ephakathi kunye nezakhiwo ezithile zentsimbi ezine-alloy ephantsi. Izinto eziqhelekileyo zesiseko ziquka amanqanaba afana ne-09Mn2Si, i-Q345 (intsimbi eqhelekileyo yaseTshayina elingana ne-ASTM A572 Gr. 50), kunye ne-09Mn2V. Iimpawu zayo ziyenza ifaneleke kwimisebenzi yokuvelisa nokulungisa kumashishini afana nokwakha, ukwakha iinqanawa, ukwenziwa kweenqanawa zoxinzelelo, kunye noomatshini abanzima ngokubanzi apho i-weld kufuneka ilingane okanye idlule ukuqina kwesinyithi esisisiseko.
Imodeli ye-AWS E7015 / J507 ingumzekelo wemveliso ephambili ngaphakathiI-Electrode yokuWelda yentsimbi yeCarbonudidi. Ingubo yayo ye-hydrogen ephantsi, kunye nokukwazi kwayo ukubambelela kuzo zonke iindawo isebenzisa i-DCEP, ijongana nemingeni eqhelekileyo ekudibaniseni iintsimbi ezibuthathaka. Ngokuhambisa isinyithi esigciniweyo ngokuthembeka okuphezulu, iipropati ezilungileyo zoomatshini, kunye nokunciphisa ukuqhekeka, le electrode inika isisombululo esithembekileyo kwiingcali ezisebenza kwiindawo ezibalulekileyo zekhabhoni kunye neentsimbi ezingasebenzi kakuhle kumacandelo ahlukeneyo emizi-mveliso.
