Apejuwe: Ni307-4 jẹ elekiturodu ti o da lori nickel pẹlu ideri iṣuu soda kekere-hydrogen.Lo DCEP (elekiturodu lọwọlọwọ taararere).O ni iṣẹ alurinmorin ti o dara julọ pẹlu ijona aaki iduroṣinṣin, spatter ti o dinku, yiyọ slag rọrun,
ati ki o lẹwa weld.
Ohun elo: O ti wa ni lilo fun alurinmorin ti nickel-chromium-irin alloys, gẹgẹ bi awọn Ni600, Ni800/800H ati iru tabi nickel-orisun superalloys pẹlu kan ṣiṣẹ otutu ti 900 ° C. O tun le ṣee lo fun awọn irin-kekere iwọn otutu ti o ni awọn irin. Ni3% ~ 9%, gẹgẹbi ASTM A333, A334, A353, A522, Alurinmorin A553 tun le ṣee lo fun alurinmorin irin ti o yatọ laarin Mo400, Ni825, irin alagbara ati irin alloy kekere.
