Inkcazo: I-J707Ni i-alloy ephantsi ye-electrode yensimbi ene-low-hydrogen ye-sodium.Sebenzisa i-DCEP (i-electrode echanekileyo yangoku) kwaye inokudityaniswa kuzo zonke izikhundla.Intsimbi egciniweyo ineempawu ezilungileyo zoomatshini.Xa kuthelekiswa ne-J707 electrode, eyona nto iphambili ye-J707Ni kukuba ukuqina kobushushu obuphantsi kunye nokumelana nokuqhekeka kuphuculwe kakhulu.
Isicelo: Isetyenziselwa ukuwelda i-alloy low-alloy high-high-high-strength steel structures of the ehambelanayo amanqanaba amandla, ezifana 14MnMoVB, WEL-TEN70 kunye Japanese HW56 kunye nezinye ezisezantsi-alloy high-amandla izakhiwo zentsimbi.

Isaziso:
1. I-electrode kufuneka ibhakwe ngeyure eli-1 kwi-350 ~ 380 ℃ ngaphambi kokusebenza kwe-welding;
2. Kubalulekile ukucoca umhlwa, isikali se-oyile, amanzi, kunye nokungcola kwiindawo zokuwelda phambi kokuba udibanise;
3. Sebenzisa umsebenzi omfutshane we-arc xa udibanisa.Umzila we-welding emxinwa ufanelekile.
