Tubabu-minɛnw bɛ baara kɛ fɔlɔ ni welding fɛɛrɛ fila ye: TIG (Gas inert inert) welding ani plasma welding. O fɛɛrɛ fila bɛɛ nafa ɲɔgɔn tɛ u la, wa u bɛ sugandi ka da tubabufura min bɛ bɔ, o ka wajibi kɛrɛnkɛrɛnnenw kan.
TIG Welding: Nafaw ni dantigɛliw .
TIG welding, n’a bɛ fɔ fana ko gazi tungsten arc welding (GTAW), o bɛ baara kɛ ni tungsten elekitorode ye min tɛ se ka tiɲɛ walasa ka welda sɔrɔ. welda yɔrɔ bɛ lakana ka bɔ nɔgɔ la ni gazi ye min tɛ se ka kɛ, a ka c’a la, argon walima heliyɔmu.
Nafaw:

Fɛn minnu bɛ nɔ bila welding technique sugandili la .
Sugandili min bɛ kɛ TIG ni plasma welding cɛ, o bɛ bɔ fɛn suguya caman na, i n’a fɔ:
– Fɛn suguya ni a bonya : Fɛn minnu ka bon, olu bɛ se ka kɛ ni joli-sira-funu ye walasa ka don a kɔnɔ ka ɲɛ.

Sugandili fɛɛrɛ sugandili bɛ se ka nɔba bila tubabufura dilanni teliya n’a baarakɛcogo ɲuman na:
– TIG welding, k’a sɔrɔ a bɛ welda ɲumanw dilan, a bɛ teliya, wa a bɛ se ka dɔ bɔ a dilanni teliya bɛɛ la.
– Plasma welding, fan dɔ fɛ, a bɛ welding teliya caman di, ka dɔ fara tube mill ka baara kɛcogo kan.
– Baarakɛcogo ɲuman bɛ se ka kɛ sababu ye ka musaka dɔgɔya ani ka nafa caman sɔrɔ tubabukan na.

welding fɛɛrɛ sugandili, a kɛra TIG ye wo, a kɛra plasma ye wo, o bɛ nɔba bila tubabukan na. Hali ni TIG welding bɛ welda ni fɛn caman di, a bɛ se ka dɔ bɔ sɛnɛfɛnw dilanni teliya la ani ka fanga sɔrɔli caya. Faan wɛrɛ fɛ, plasma welding bɛ welding teliya teliya ani ka don kosɛbɛ nka a bɛ se ka kɛ sababu ye ka masinw cogoya caman sɔrɔ.
