E7015-G Hydrogene Ntoya ya Sodium Ipfunyika Amashanyarazi
DESCRIPTION:
Nubushyuhe buke bwo gusudira ibyuma hamwe na sodium ya hydrogène nkeya irimo nikel.Umwanya wuzuye wo gusudira urashobora gukorwa na dc ihuza.Muri -80 ° C icyuma gisudira kiracyafite ingaruka nziza zo gukomera.
UKORESHE:
Weld -80 ° C ikora 1.5Ni ibyuma byubaka.

AMABWIRIZA:
1.Ibikoresho bya electrode bigomba gutekwa munsi ya 350-400 ℃ isaha imwe mbere yo gusudira, bigashyirwa mumashanyarazi kandi bigashyirwa mugihe bikenewe.
2.Ikizinga kuri weld nkicyuma kigomba kuvaho, kandi gusudira bigomba gushyuha kugeza kuri 200 ℃.
3.Weld irashobora gushukwa munsi ya 600-650 ℃ nyuma yo gusudira kugirango ikureho imihangayiko y'imbere.
