GB / T ENi6093

AWS A5.11 ENiCrFe-4

Ibisobanuro: Ni307-4 ni electrode ishingiye kuri nikel hamwe na sodium ya hydrogène nkeya.Koresha DCEP (electrode igezwehobyiza).Ifite imikorere myiza yo gusudira hamwe na arc ihamye, gutwika gake, gukuramo byoroshye,

na weld nziza.

Gushyira mu bikorwa: Irakoreshwa mu gusudira nikel-chromium-fer ivanze, nka Ni600, Ni800 / 800H hamwe na superalloys isa cyangwa nikel ifite ubushyuhe bwakazi bwa 900 ° C. Irashobora kandi gukoreshwa mubyuma bifite ubushyuhe buke burimo Ni3% ~ 9%, nka ASTM A333, A334, A353, A522, Gusudira A553 birashobora kandi gukoreshwa mugusudira ibyuma bidasa hagati ya Mo400, Ni825, ibyuma bidafite ingese hamwe nicyuma gito.

Ibigize imiti yicyuma (%):

Ibikoresho bya tekinike yicyuma gisudira:

Icyifuzo kigezweho:

Icyitonderwa:

1. Electrode igomba gutekwa kumasaha1 hafi 300 ℃ mbere yo gusudira;

2. Ni ngombwa guhanagura ingese, amavuta, amazi, n’umwanda ku bice byo gusudira mbere yo gusudira.Gerageza gukoresha arc ngufi kugirango usudire.
