Inkcazo: I-J707RH yi-electrode ye-hydrogen eyomeleleyo kakhulu ene-hydrogen sodium ephantsi. Sebenzisa i-DCEP (i-electrode yangoku ngqo) kwaye ingadityaniswa kuzo zonke iindawo. Ukusebenza kwenkqubo yokudityaniswa kwentsimbi kulungile. Ukugoba okubandayo, ukumelana nokuqhekeka kunye nokumelana nokuqhuma kwamalungu adibeneyo kulungile. Isinyithi esigciniweyo sinobunkunkqele obukhulu kunye nokuqina.

Ukusetyenziswa: Isetyenziselwa ukuwelda izakhiwo zehashe, kwaye ikwafanelekile ukuwelda izakhiwo ezibalulekileyo zentsimbi enamandla aphezulu ye-Rp0.2≥590MPa.

Isaziso:

1. I-electrode mayibhakwe iiyure ezi-2 kwi-400℃ ngaphambi kokuba isebenze nge-welding;

2. Kubalulekile ukucoca umhlwa, isikali seoyile, amanzi, kunye nokungcola kwiindawo zokuwelda ngaphambi kokuba kuweldwe;

3. Sebenzisa i-arc operation emfutshane xa udibanisa. Indlela yokuncamathela ebhityileyo ifanelekile.
