Inkcazo: I-W707Ni yi-electrode yentsimbi enobushushu obuphantsi equlethe i-Ni kwi-hydrogen sodium coating ephantsi. Sebenzisa i-DCEP (i-electrode yangoku ngqo) kwaye ingadityaniswa kuzo zonke iindawo. Isinyithi esifakwe kwi-depositi sisenokuqina okuhle kwi--70°C.

Isicelo: Isetyenziselwa ukuwelda intsimbi enobushushu obuphantsi efana ne-2.5Ni.

 Isaziso:

  1. I-electrode kufuneka ibhakwe iyure e-1 kwi-350℃ ngaphambi kokuba isebenze nge-welding;
  2. Kubalulekile ukucoca umhlwa, isikali seoyile, amanzi, kunye nokungcola kwiindawo zokuwelda ngaphambi kokuba uwelda;
  3. Zama ukusebenzisa amandla amancinci xa udibanisa iintambo, usebenzisa iileya ezininzi kunye ne-multi-pass welding.
