Kwicandelo lokwenziwa nokwakhiwa kwesinyithi, ingakumbi kumsebenzi wepayipi kunye nowesakhiwo sentsimbi, ukukhethwa kwezinto ezisetyenziswayo ezifanelekileyo kubalulekile ukuze kuhlanganiswe kakuhle.I-Electrode yokuWeldayinxalenye ebalulekileyo kwi-shielded metal arc welding (SMAW), eneentlobo ezithile ezenzelwe ukusetyenziswa ezahlukeneyo. Eli nqaku libonelela ngenkcazo yobuchwephesha yohlu lwe-AWS E6010, i-electrode esetyenziswa kakhulu kwi-carbon steel welding, egxile kwiimpawu zayo kunye nokusetyenziswa kwayo okuphambili.
I-electrode ekuxoxwa ngayo, ebizwa ngokuba yi-J425G kwimigangatho ethile kwaye ihambelana nokuhlelwa kwe-AWS E6010 kunye ne-GB/T E4310, luhlobo oluthile lwe-Welding Electrode. Inesigqubuthelo se-sodium esine-cellulose ephezulu. Olu lwakhiwo lwesigqubuthelo lubalulekile kwiimpawu zalo zokusebenza, luvelisa i-arc enamandla, yokumba kunye nesikhuselo segesi esikhulu esikhusela ichibi le-weld elinyibilikisiweyo, ngakumbi kwiindawo ezinzima.
Uphawu oluchaza okuI-Electrode yokuWeldaNgaba ifanelekile kwindlela yokuwelda ethe tye. Yenzelwe ukusetyenziswa nge-Direct Current Electrode Positive (DCEP) polarity. Olu dibaniso luvumela abawelda ukuba benze ukuwelda kweendawo zonke kwee-circumferential welds (ii-pipe circumferential welds) ngesantya esiphezulu se-welding. Uphawu lokungena olujulileyo lwe-E6010 lubalulekile ekufezekiseni ukuhlanganiswa okupheleleyo kweengcambu.
Umgaqo wokusebenza wale Welding Electrode unceda kwisiphumo esithile nesixabisekileyo kwi-pipe welding: ukukwazi ukwenza i-single-side root weld ekhokelela ekungeneni kwesandi kunye nokwakheka kwicala elingasemva (ngaphakathi) lombhobho, indlela eyaziwa ngokuba yi-"open root welding". Oku kususa isidingo sokugoba umva kwizicelo ezininzi, okuphucula kakhulu ukusebenza kakuhle kokwakhiwa kwemibhobho eyahlukeneyo yentsimbi yekhabhoni kunye namalungu olwakhiwo.
Udidi lwe-E6010 lumele isixhobo esikhethekileyo nesibalulekileyo kudidi olubanzi lweI-Electrode yokuWeldaiimveliso. Ingubo yayo ephezulu ye-cellulose, ukungena kwayo nzulu, kunye nokukwazi kwayo ukuhla ngokuthe nkqo kwenza ukuba ibe lolona khetho lukhethwayo lweengcambu kunye neepaseji ezishushu kwi-pipeline welding kunye nezinye izinto ezenziwe ngentsimbi yekhabhoni. Ukuqonda iinkcukacha zobugcisa kunye nokusetyenziswa okucwangcisiweyo kwale Welding Electrode kubalulekile ekuqinisekiseni ii-welds eziqinileyo nezithembekileyo kwiiprojekthi zeziseko ezibalulekileyo.
