Xa kudityaniswa iintsimbi ezinobushushu obuphantsi, ukukhetha i-electrode efanelekileyo kubalulekile ekufezekiseni ii-welds ezikumgangatho ophezulu nezihlala ixesha elide. I-W107 (AWS E7015-C2L) yi-electrode ebalaseleyo kwimarike. Le yi-electrode ebalaseleyo.i-electrode yentsimbi enobushushu obuphantsiYenzelwe ukuba ibe ne-hydrogen sodium coating ephantsi, nto leyo eyenza ukuba ilungele ukusetyenziswa kwe-welding kwiindawo ezinobushushu obuphantsi. Iyakwazi ukugcina ukuqina okuhle kwempembelelo ukuya kuthi ga kwi--100°C, i-W107 electrode sisisombululo esithembekileyo kwiiprojekthi ze-welding ezifuna ukusebenza okuphezulu kwiimeko ezibandayo kakhulu.
Intonga yokuwelda ye-W107 yenzelwe ngokukodwa ukuwelda ngentsimbi enobushushu obuphantsi kwaye inika iziphumo ezibalaseleyo zokuqina nokuqina. Ingubo yayo yesodium enehydrogen ephantsi iqinisekisa ukufunxwa okuncinci kwehydrogen ngexesha lokuwelda, okubalulekileyo ukuthintela ukuqhekeka nokuqinisekisa ukuthembeka kwe-weld. Oku kwenza ukuba ibe lolona khetho lokuqala lokuwelda izakhiwo ezibalulekileyo kunye nezinto ezivezwe kumaqondo obushushu aphantsi, njengeetanki ze-cryogenic, iipayipi kunye nezixhobo ezisetyenziswa kwiindawo ezibandayo.
Enye yezona mpawu ziphambili ze-electrode ye-W107 kukuguquguquka kwayo kwiindawo zokuwelda. Nokuba yi-vertical, tyaba, i-overhead okanye i-flat welding, le electrode ingasetyenziswa kuzo zonke iindawo, inika abawelda ukuguquguquka kunye nokulula ukusebenza kwiiprojekthi ezahlukeneyo. Ukongeza, i-electrode yenzelwe ukusetyenziswa ne-DC Positive Electrode (DCEp) ukuze kufezekiswe ukusebenza kakuhle nokuzinzileyo kokuwelda kwizicelo ezahlukeneyo zokuwelda.
Isinyithi esifakwe kwi-electrode ye-W107 sigcina ukuqina okugqwesileyo kwempembelelo nokuba kumaqondo obushushu aphantsi kakhulu, nto leyo eyenza ukuba ibe lukhetho oluthembekileyo lokusetyenziswa apho i-weld iphantsi kweemeko ezibandayo kakhulu. Olu kuqina lubalaseleyo luqinisekisa ukuba i-weld igcina ukuqina kwayo kunye nokusebenza kwayo nokuba kwiindawo ezingaphantsi kwe-zero, inika ukuthembeka kwexesha elide kunye nokhuseleko kwiindawo ezi-welded.
Ngamafutshane, i-W107 (AWS E7015-C2L) I-Low Temperature Steel Welding Rod sisisombululo esiphezulu kwizicelo ze-welding ezifuna ukusebenza okuphezulu kwiindawo ezinobushushu obuphantsi. I-hydrogen sodium coating yayo ephantsi kunye nokukwazi kwayo ukugcina ukuqina okuhle kwi--100°C kuyenza ibe lukhetho oluhle kakhulu kubashicileli abafuna iziphumo ezisemgangathweni ophezulu nezithembekileyo kwiimeko ezibandayo kakhulu. Ngenxa yokuguquguquka kwendawo yayo yokushicilela kunye nokuhambelana ne-DCEP, i-W107 electrode inika abashicileli ukuzithemba kunye nokuqinisekisa ukuba bayayidinga ukujongana neeprojekthi ze-welding zentsimbi ezinobushushu obuphantsi ngokuchanekileyo nangokugqwesa.
