Nickel naNickel Alloy Welding Electrode
Ni307-4
GB/T ENi6093
AWS A5.11 ENiCrFe-4
Nkọwa: Ni307-4 bụ electrode dabeere na nickel nke nwere mkpuchi sodium dị ala.Jiri DCEP (electrode ugbu a kpọmkwemnti).Ọ nwere arụmọrụ ịgbado ọkụ dị mma yana ọkụ arc kwụsiri ike, obere spatter, iwepu slag dị mfe,
na ọmarịcha weld.
Ngwa: Ọ na-eji maka ịgbado ọkụ nke nickel-chromium-ígwè alloys, dị ka Ni600, Ni800/800H na yiri ma ọ bụ nickel dabeere superalloys na a na-arụ ọrụ okpomọkụ nke 900 Celsius C. Ọ nwekwara ike-eji maka ala-okpomọkụ steels nwere. Ni3% ~ 9%, dị ka ASTM A333, A334, A353, A522, The ịgbado ọkụ nke A553 nwekwara ike-eji maka dissimilar metal ịgbado ọkụ n'etiti Mo400, Ni825, igwe anaghị agba nchara na ala alloy ígwè.
Ngwakọta kemịkalụ nke igwe weld (%):

Akwadoro ugbu a:
Dayameta mkpanaka (mm) | 2.5 | 3.2 | 4.0 |
Welding ugbu a (A) | 60 ~ 90 | 80 ~ 110 | 110 ~ 150 |
Mara:
1. The electrode ga-abụọ maka 1 hour na gburugburu 300 ℃ tupu ịgbado ọkụ ọrụ;
2. Ọ dị mkpa iji kpochaa nchara, mmanụ, mmiri na adịghị ọcha na akụkụ ịgbado ọkụ tupu ịgbado ọkụ.Gbalịa iji obere arc iji weld.
