Uma ushisela izinsimbi ezishisa kancane, ukukhetha i-electrode efanele kubalulekile ekufinyeleleni ama-weld asezingeni eliphezulu futhi aqinile. I-W107 (AWS E7015-C2L) iyi-electrode evelele emakethe. Lokhui-electrode yensimbi enokushisa okuphansiYakhelwe nge-hydrogen sodium coating ephansi, okwenza kube kuhle kakhulu ekusetshenzisweni kokushisela ezindaweni ezishisa kakhulu. Ikwazi ukugcina ukuqina okuhle komthelela kuze kufike ku--100°C, i-W107 electrode iyisisombululo esithembekile samaphrojekthi okushisela adinga ukusebenza okuphezulu ezimweni ezibandayo kakhulu.
Induku yokushisela ye-W107 yenzelwe ngokukhethekile ukushisela insimbi enezinga lokushisa eliphansi futhi inikeza imiphumela emihle kakhulu yamandla nokuqina. Isembozo sayo se-sodium esingena-hydrogen esincane siqinisekisa ukumuncwa okuncane kwe-hydrogen ngesikhathi sokushisela, okubalulekile ukuvimbela ukuqhekeka nokuqinisekisa ubuqotho be-weld. Lokhu kwenza kube ukukhetha kokuqala kokushisela izakhiwo ezibalulekile kanye nezingxenye ezivezwe emazingeni okushisa aphansi, njengamathangi e-cryogenic, amapayipi kanye nemishini esetshenziswa ezindaweni ezibandayo.
Esinye sezici eziyinhloko ze-electrode ye-W107 ukuguquguquka kwayo ezindaweni zokushisela. Kungakhathaliseki ukuthi iqonde phezulu, ivundlile, ingaphezulu noma i-flat welding, le electrode ingasetshenziswa kuzo zonke izikhundla, inikeze abashisela ukuguquguquka kanye nokulula ukusebenza kumaphrojekthi ahlukahlukene. Ngaphezu kwalokho, i-electrode yenzelwe ukusetshenziswa ne-DC Positive Electrode (DCEp) ukuze kufezwe ukusebenza kahle nokuzinzile kokushisela ezinhlotsheni ezahlukene zokushisela.
Insimbi efakwe ku-W107 electrode igcina ukuqina okuhle kakhulu komthelela ngisho noma amazinga okushisa aphansi kakhulu, okwenza kube ukukhetha okuthembekile kokusetshenziswa lapho i-weld ibhekene nezimo ezibandayo kakhulu. Lokhu kuqina okungavamile kuqinisekisa ukuthi i-weld igcina ubuqotho bayo besakhiwo kanye nokusebenza kwayo ngisho nasezindaweni ezingaphansi kwezinga-zero, okuhlinzeka ngokuthembeka kwesikhathi eside kanye nokuphepha kwezingxenye ezi-welded.
Ngamafuphi, i-W107 (AWS E7015-C2L) Induku Yokushisela Yensimbi Esezingeni Eliphansi iyisisombululo esiphezulu sezinhlelo zokusebenza zokushisela ezidinga ukusebenza okuphezulu ezindaweni eziphansi zokushisa. Isembozo sayo se-hydrogen sodium esiphansi kanye nekhono layo lokugcina ukuqina okuhle komthelela ku--100°C kwenza kube ukukhetha okuhle kakhulu kwabashisela abafuna imiphumela esezingeni eliphezulu nethembekile ezimweni ezibandayo kakhulu. Ngokusebenziseka kwayo kokushisela kanye nokuhambisana ne-DCEP, i-electrode ye-W107 inikeza abashisela ukuzethemba kanye nesiqinisekiso abasidingayo ukuze babhekane namaphrojekthi okushisela ensimbi esezingeni eliphansi ngokunemba nangokuhle.
