Welding yɛ adeyɛ titiriw a ɛma wɔde dade a ɛnyɛ den a wɔde yɛ nneɛma no bom, titiriw wɔ nsu afiri a wɔde weld ayɛ mu.

Dɛn ne intergranular corrosion?
Intergranular corrosion ba wɔ austenitic stainless steel a entumi nnyina no mu a carbon a ɛwɔ mu no boro 0.03%. Sɛ wɔde chromium carbides yɛ no hyew wɔ 425-815°C ntam anaasɛ ɛma ɛyɛ nwini nkakrankakra a, chromium carbides no pue wɔ aburow hye so. Saa chromium a ɛso tew yi wɔ aburow hye so mmeae no ma dade no yɛ mmerɛw sɛ ɛbɛsɛe wɔ mmeae a ɛyɛ basabasa no. Wɔ adwennwen mu no, dade no betumi abubu wɔ saa aburow hye a ayɛ mmerɛw yi so, na ɛde ahoɔden a ɛso tew kɛse ne nsɛe a ɛko tia no ba.
Nneɛma a ɛma intergranular corrosion ba:
Carbon a ɛdɔɔso: Carbon dodow a ɛkɔ soro wɔ dade mu no ma chromium carbides a ɛba no yɛ kɛse.
Ɔhyew a wɔde hyɛ mu: Bere tenten a wɔde kyerɛ sɛnea obi te nka wɔ ɔhyew mu (425-815°C) bere a wɔreyɛ welding anaa ɔhyew no.
