Welding ye baara nafamaba ye walasa ka fɛnw fara ɲɔgɔn kan minnu tɛ sɔgɔ, kɛrɛnkɛrɛnnenya la, welda pibilikiw dilanni na. Nka, welda tiɲɛniw, kɛrɛnkɛrɛnnenya la welda yɔrɔ la, olu bɛ se ka nɔba bila fɛn laban in dafalen na ani a kɛcogo la. Ko gɛlɛn dɔ ye intergranular corrosion ye, o ye localized corrosion sugu dɔ ye min bɛ se ka kɛ sababu ye ka bɔnɛba sɔrɔ.
Intergranular corrosion ye mun ye?
Intergranular corrosion bɛ sɔrɔ austenitic inox steel basigibali la ni carbone hakɛ bɛ tɛmɛ 0,03% kan. Ni a sumana 425-815°C cɛ walima ka nɛnɛ dɔɔni dɔɔni o funteni hakɛ la, chromium carbides bɛ teliya suman dancɛw la. O kolosinsinnanw dɔgɔyali suman dancɛ yɔrɔw la, o bɛ nɛgɛ kɛ fɛn ye min bɛ se ka sɔgɔ sigida juguw la. Degun kɔrɔ, nɛgɛ bɛ se ka kari nin suman dancɛ barikamaw kan, o bɛ na ni fanga ni sɔgɔli kɛlɛli ye kosɛbɛ.
Fɛn minnu bɛ kɛ sababu ye ka fɛnɲɛnamafagalanw (conrosion intergranular) kɛ:
Kabon hakɛ caman: Karɔbɔni hakɛ kɔrɔtalen nɛgɛ la, o bɛ kɛ sababu ye ka kuromu karɔbidiw dilan.
Funteni hakɛ sɔrɔli : a bɛ mɛn sen na sɛgɛsɛgɛli funteni hakɛ la (425-815°C) a sɔgɔli walima a funteni furakɛli waati.
Sigida minnu bɛ kɛ ka fɛnw tiɲɛ: Ni u bɛ kɛ ni fɛn juguw ye, i n’a fɔ asidi walima kuloriw, olu bɛ teliya ka sɔgɔli kɛcogo teliya.
