1. welda hakɛ tɛ sariyaw dafa .
Welda hakɛ tɛ wajibiyalenw dafa kɛrɛnkɛrɛnnenya la welda barika ni barikalan danfara, welda bonya ni a bonya danfara, ɲɔgɔndanbaliya, ɲɔgɔndɛmɛ kɔfɛ sɛgɛsɛgɛli ani hakɛ wɛrɛw minnu tɛ sariyaw dafa, welda janya tɛ kelen ye, bonyabaliya, ani deformation belebeleba. Welda bonyabaliya tɛna kɛ sababu ye dɔrɔn ka welda cogoya kɛ fɛn ye min tɛ mɔgɔ ɲɛnajɛ, nka a bɛ nɔ bila fana sirili fanga la welda ni nɛgɛ basigilen cɛ Ni welda fanga bonya kojugu, o bɛna degun caman lase mɔgɔ ma, wa ni welda ka dɔgɔn ni nɛgɛ basigilen ye, a tɛna barika sɔrɔ ka ɲɛ. Joli fanga; Fɛn jugu ni jiginni kojugu bɛna fanga jiginni tiɲɛ ani ka degun hakɛ caya, o bɛ na ni fanga dɔgɔyali ye.
A sababuw: Bevel angle walima edge blunt bɛnbali ani pipe inox welded pipe min tɛ kelen ye; welding process parameters (sɔgɔli taabolo paramɛtɛrɛw) sugandili cogo min tɛ se ka kɛ; Low level of welder ka baarakɛcogo, a ɲɔgɔnnaw.
Bana kunbɛn fɛɛrɛw: Aw bɛ groove angle ani assembly clearance bɛnnen sugandi; ka lajɛ kɛcogo ɲɛ ka taa a fɛ; welding process paramètres bɛnnenw sugandi; welda ka baarakɛcogo ɲuman hakɛ, a ɲɔgɔnnaw ɲɛ.
2. Undercut .
K’a sababu kɛ welding process parameters (sɔgɔli kɛcogo paramɛtɛrɛw) sugandili jugu ye walima baarakɛcogo jugu, groove walima depression min bɛ sɔrɔ nɛgɛ basigilen wuli fɛ welda senkɔni kan, o bɛ wele ko undercut. Undercut tɛ dɔrɔn ka pipe welded joli weldalen fanga dɔgɔya dɔrɔn, nka a bɛ kɛ sababu ye fana ka kariw kɛ nɔgɔya la ka da degun hakɛ kan.
A sababuw : kɛrɛnkɛrɛnnenya la, kuran ka bon kojugu, arc janya ka bon kojugu, elekitorode kɛrɛ tɛ bɛn, wa elekitorode tacogo man ɲi.
Bana kunbɛn fɛɛrɛw: Aw bɛ welding current bɛnnen ni welding teliya sugandi ni aw bɛ welding kɛ ni elekitorode arc welding ye.
A ka c’a la, ni welding teliya bɛ teliya, arc bɛna sama ka taa ɲɛfɛ ka taa a fɛ. Yala fɛɛrɛ bɛ yen walasa ka arc janya normale sabati ani ka a jira ko a bɛ se ka baara kɛ ka sɔrɔ a ma sumaya wa? Hangao Tech bɛ se k’i dɛmɛ. An yɛrɛ yiriwali . Electromagnetic control arc stabilisation system , min bɛ se ka bɛn ni inox tube mill line suguya caman ye a ladilanni kɔfɛ, ni a bɛ cogo min na ka welding teliya sabati, o bɛ arc sama ka taa a jɔyɔrɔ la magnetic field fɛ. A tɛ nɔ bila welding quality la, nka a bɛ a ka baara kɛcogo ɲuman fana sabati.
3. A ma don .
Donda dafabali bɛ tali kɛ ko kɛlen na ko joli weldalen ju tɛ don pewu ni pipe min bɛ sɔgɔ ni nɛgɛ ye, o bɛ sɔgɔ. Donni dafabali bɛna kɛ sababu ye ka degun hakɛ caya ani ka faraw bila nɔgɔya la. Joli nafamaw minnu bɛ welda la, olu man kan ka don u la cogo dafalen na.
A sababuw : groove angle walima gap ka dɔgɔn kojugu, a da blunt ka bon kojugu, wa a lajɛli man ɲi; Welding process parameters bɛ sugandi cogo bɛnbali la, welding current ka dɔgɔ kojugu, welding teliya bɛ teliya kojugu; Welder ka baarakɛcogo tɛ ɲɛ, a ɲɔgɔnnaw.
Fɛɛrɛw tigɛcogo : groove hakɛ sugandili n’a baaracogo ɲuman, a lajɛcogo ɲuman, a labɛnni ka ɲɛ, a bɛ welding current ani welding teliya bɛnnen sugandi, ka welder ka baarakɛcogo fɛɛrɛ hakɛ ɲɛ, a ɲɔgɔnnaw.
4. A ma fused totally .
Fusion dafabali bɛ tali kɛ welda biɲɛ ni a basigilen nɛgɛ ni welda biɲɛ ni welda biɲɛ ni ɲɔgɔn cɛ cogo dafalen na fusion welding waati. Fusion dɛsɛ bɛ dɔ bɔ joli la, o bɛ dɔ bɔ joli la, wa fusion dɛsɛ jugumanba bɛna a to weldalen jɔcogo tɛ se ka muɲu hali dɔɔnin.
sababuw : kɛrɛnkɛrɛnnenya la, teliya ni welding current (kurunba welding) welding welded pipes (sɔgɔli weldalen pipew) fɛ, welding heat input (sɔgɔli funteni donta) ka dɔgɔ kojugu; Welding rod ye eccentrique ye, angle min bɛ welding bere ni welda cɛ, o tɛ bɛn, wa arc pointing bɛ deflected; Nɔgɔ ni nɔgɔ bɛ sɔrɔ jiribolo kɛrɛfɛ kogo la, saniya dafabali bɛ kɛ layiniw ni ɲɔgɔn cɛ.
Bana kunbɛn fɛɛrɛw : Aw bɛ welding process parameters sugandi ka ɲɛ, ka baara kɛ ka ɲɛ, ka interlayer saniya, ani ka welda baarakɛcogo hakɛ ɲɛ, a ɲɔgɔnnaw.
5. welding tumour .
welda kuru bɛ nɛgɛ kuru min bɛ sɔrɔ nɛgɛ wulilen fɛ min bɛ woyo ka taa nɛgɛ basigilen min ma mɔlen ye welda kɔfɛ welding kɛtuma na. Welda biɲɛ tɛ dan pipe weldalen weldalen ka welda sɔgɔli cogoya dɔrɔn ma, nka a ka ca a la, a ka teli ka kɛ ni sɔgɔli ye ani ka dondaw dafa dafabali la welda biɲɛ yɔrɔ la.
A sababuw: A dafɛla ka dɔgɔn kojugu ani a ju bɛ bonya kojugu; welding current ka bon ani welding teliya bɛ teliya; welda ka baarakɛcogo seko hakɛ ka dɔgɔ, a ɲɔgɔnnaw.
Bana kunbɛn fɛɛrɛw : Aw bɛ welding process parameters bɛnnenw sugandi ka kɛɲɛ ni welding positions suguya wɛrɛw ye, ka fusion hole bonya kɔlɔsi kosɛbɛ, ani ka welder ka baarakɛcogo fɛɛrɛ hakɛ ɲɛ, a ɲɔgɔnnaw.
Ka da an ka ko kɛlenw kan, kun 10 bɛ yen a dɔgɔyalenba la. Bi an ye 5 fɔlɔw lajɛ. Aw ye an ka siti in lajɛ walasa ka kunnafoni kuraw sɔrɔ.
