Emkhakheni wokwenziwa nokwakhiwa kwensimbi, ikakhulukazi emsebenzini wepayipi kanye nowesakhiwo sensimbi, ukukhethwa kwezinto ezisetshenziswayo ezifanele kubalulekile ukuze kuhlanganiswe kahle.I-Electrode Yokushiselaiyisakhi esiyisisekelo ekushiseni insimbi evikelwe (i-SMAW), enezinhlobo ezithile ezenzelwe ukusetshenziswa okuhlukile. Lesi sihloko sinikeza incazelo yobuchwepheshe yokuhlukaniswa kwe-AWS E6010, i-electrode esetshenziswa kabanzi yokushiseni insimbi yekhabhoni, egxile ezicini zayo kanye nokusetshenziswa kwayo okuyinhloko.
I-electrode okuxoxwa ngayo, ebizwa ngokuthi i-J425G kwezinye izindinganiso futhi ehambisana nezigaba ze-AWS E6010 kanye ne-GB/T E4310, uhlobo oluthile lwe-Welding Electrode. Inesimbozo se-sodium esine-cellulose ephezulu. Lokhu kwakheka kwesimbozo kuyisihluthulelo sezakhiwo zayo zokusebenza, kudala i-arc enamandla, yokumba kanye nesivikelo segesi esikhulu esivikela ichibi lokushisela elincibilikisiwe, ikakhulukazi ezindaweni ezinzima.
Isici esichazayo salokhuI-Electrode Yokushiselaingabe ifanelekile inqubo yokushisela eqonde phansi. Yenzelwe ukusetshenziswa nge-Direct Current Electrode Positive (DCEP) polarity. Le nhlanganisela ivumela abashiseli ukuthi benze ukushisela okubekwe endaweni yonke kwama-circumferential welds (ama-pipe circumferential welds) ngesivinini esikhulu sokushisela. Isici sokungena okujulile kwe-E6010 sibalulekile ekufezeni ukuhlanganiswa okuphelele kwama-root pass.
Isimiso sokusebenza sale Welding Electrode senza kube lula ukuthola umphumela othize nobalulekile ekushiseni amapayipi: ikhono lokwenza i-root weld eyodwa eholela ekungeneni komsindo kanye nokwakheka komsindo ngemuva (ngaphakathi) kwepayipi, inqubo eyaziwa ngokuthi i-"open root welding". Lokhu kuqeda isidingo sokugoba ingemuva kwezicelo eziningi, okuthuthukisa kakhulu ukusebenza kahle kokwakhiwa kwamapayipi ahlukahlukene ensimbi yekhabhoni kanye namajoyinti esakhiwo.
Ukuhlukaniswa kwe-E6010 kumelela ithuluzi elikhethekile nelibalulekile ngaphakathi kwesigaba esibanzi se-I-Electrode Yokushiselaimikhiqizo. Isembozo sayo se-cellulose ephezulu, ukungena okujulile, kanye nekhono layo lokuma phansi liyenza ibe yisinqumo esikhethwayo sezimpande kanye nokushintshashintsha okushisayo ekushiseni kwamapayipi kanye nokunye ukwenziwa kwensimbi yekhabhoni. Ukuqonda imininingwane yobuchwepheshe kanye nokusetshenziswa okuhlosiwe kwale Welding Electrode kubalulekile ekuqinisekiseni ukushintshwa okuqinile nokuthembekile kumaphrojekthi engqalasizinda ebalulekile.
