ɲininkali .

Porosity ye fiɲɛ ye min bɛ sɔrɔ pipe inox welding na, o min bɛ jira i n’a fɔ dingɛ misɛnniw welda kɔnɔ, o bɛ nɔ bila pipew sirili n’u fanga la. Ninnu ye fɛɛrɛ ye min faamuyali ka nɔgɔn walasa ka stomata sababuw ɲɛfɔ ani u ɲɛnabɔcogo:

1. Pores bɛ bɔ min?

1.1 Gazi tolenw .

Nɛgɛ min bɛ wuli welding waati la, o bɛ gazi laminiw minɛ (i n’a fɔ oksizɛni ni azote fiɲɛ na).

Ni gazi min bɛ lakana (i n’a fɔ argon) o ma dafa walima a ma saniya kosɛbɛ, o gaziw tɛ se ka bɔ ka tɛmɛ ni nɛgɛ nɛnɛna, ka bugunw dilan.

1.2 Fɛnw tɛ saniya .

Tumu, ji nɔgɔ walima nɔgɔ bɛ sɔrɔ nɛgɛdaga sanfɛ, ani gazi i n’a fɔ idɔrɔzi bɛ tiɲɛ funteni caman na, ka ɲagami ka don welda la.

1.3 welding bɛnbali .

Kuran ka bon kojugu wa a teliya ka bon kojugu: Pool molten ka funteni ka bon kojugu walima a solidifier bɛ teliya kojugu, wa gazi tɛ se ka bɔ.

Angle jugu min bɛ welding torch la: Gazi min bɛ a tanga fiɲɛ ma, o bɛ fiyɛ, fiɲɛ bɛ don jidaga la.


2. Aw bɛ se ka aw yɛrɛ tanga fiɲɛ dingɛw ma cogo di?

2.1 kɔlɔn saniyalen .

Aw bɛ tulu, nɔgɔ ani ji saniya ka bɔ pipe sanfɛla la ka ɲɛ ni cɛncɛn walima dɔlɔ ye sani aw ka welding kɛ.

2.2 Gazi min bɛ kɛ ka a tanga, o bɛ se ka kɛ .

Argon ni saniya ≥99,99% bɛ kɛ ani a jibɔ hakɛ bɛ mara 15-20L/min.

Aw bɛ aw yɛrɛ tanga welding ma fiɲɛ barikama sigida la, min bɛ se ka lakana fiɲɛ fɛ.

2.3 Aw bɛ welding paramɛtiriw ladilan .

Aw bɛ kuran bɛnnen sugandi (i n’a fɔ 90-120A for 1.2mm welding wire) walasa ka aw tanga kuran kojugu ma.

welding teliya bɛ kɛ kelen ye, a tɛ teliya kojugu (8-12cm/min ka ɲi).

2.4 Butt welding material sugandi .

Aw bɛ siliyɔmu (SI) walima titaniyɔmu (TI) kɛ ni nɛgɛ ye, i n’a fɔ ER308LSI, walasa ka gazi bɔli dɛmɛ.

Flux-cored wire bɛ ni porosity resistance ɲuman ye ka tɛmɛ solide wire kan.

2.5 Baarakɛcogo ɲuman .

Aw bɛ a to a ɲɛkisɛ ni a baarakɛminɛn cɛ 75° ɲɔgɔn na walasa gazi ka se ka a yɛrɛ datugu jida la.


Porozɛ in bɛ sɔrɔ gazi tolenw fɛ ani baara kɛcogo jugu de fɛ. Ni i ye fɛn saniya, ka gazi mara ani ka paramɛtɛrɛw ladilan, i bɛ se ka dɔ bɔ kosɛbɛ porosity la ani ka welding ɲumanya sabati!
