i n' a fɔ tutigɛbagaw ka tɔn min bɛ san 1990 la . Inox Industrial welded pipe production equipment industry, Hangao tech . bɛ dantigɛliw sɔrɔ ka bɔ baarakɛlaw ka ko kɛlenw na. Bi, an bɛ baro kɛ ka bɔ fɛɛrɛko siratigɛ la, n’an bɛ gazi lakanani fɛn caman Changer dɔrɔn, nin nɔ nafama duuru bɛna bɔ welding kɛcogo la:
(1) Ka welding wire deposition rate ɲɛ ka a suma ni laadala gazi ɲuman saniyalen ye, a ka c’a la, gazi ɲagaminen min falen bɛ argon na, o bɛ na ni fɛn dilanni nafa ka bon. Argon hakɛ ka kan ka tɛmɛ 85% kan walasa ka jet transition sɔrɔ. Tiɲɛ don, walasa ka welding wire deposition rate ɲɛ ka ɲɛ, o bɛ ɲini ka welding paramètres bɛnnenw sugandi. A ka c’a la, welding effect (sɔgɔli nɔ) bɛ sɔrɔ paramɛtɛrɛ caman de la. A ka c’a la, welding paramètre sugandili bɛnbali bɛna dɔ bɔ welding nafa la ani ka dɔ fara slag bɔli baara kan welding kɔfɛ.
(2) Ka spatter kɔlɔsi ani ka argon ka ionisation potentiel dɔgɔyalen dɔgɔya welding slag saniya kɔfɛ, o bɛ arc sabatili ɲɛ ani ka o cogo la ka spatter dɔgɔya. Kɔsa in na, welding power technology kura bɛ gazi ɲuman welding (gazi ɲuman) sɔgɔli kɔlɔsi. O cogo kelen na, ni gazi ɲagaminen bɛ baara kɛ, a bɛ se ka dɔ bɔ a la ka taa a fɛ ani ka welding paramɛtiri finɛtiri bonya.
(3) Aw bɛ welding seam formation kunbɛn, ka gazi ɲuman welding welding welding dɔgɔya ka teli ka bɔ kɛnɛma, o bɛ na ni welding kojugu ye ani ka welding musaka caya. Gazi ɲagaminen argon ka nɔgɔn ka se ka welding seam formation ani ka i yɛrɛ tanga welding wire tiɲɛni ma.
(4) Aw bɛ welding teliya ɲɛ. Ni baara kɛra ni gazi ɲagaminen ye min falen bɛ argon na, hali ni welding current bɛ caya, a bɛ se ka kɛ ko spatter bɛ se ka kunbɛn kosɛbɛ. Nafa min bɛ sɔrɔ o la, o ye welding teliya bonya ye, kɛrɛnkɛrɛnnenya la welding automatique (otomatiki welding) la, o bɛ fɛn dilanni nafa bonya kosɛbɛ.
(5) welding fume control. O welding baarakɛcogo kelenw kɔnɔ, argon-rich ɲagaminen bɛ dɔ bɔ kosɛbɛ welding fume la ni i ye a suma ni gazi ɲuman ye. Ni an y’a suma ni wari bilali ye fɛnɲɛnamafagalanw na walasa ka welding baara kɛyɔrɔ yiriwa, gazi ɲagaminen min falen bɛ argon na, o baara ye nafa ye min bɛ sɔrɔ a la walasa ka dɔ bɔ sɔrɔyɔrɔ nɔgɔli la.
Kuma bɛɛ la, a bɛ se k’a ye ko ni i ye gazi welding shielding bɛnnen sugandi, welding quality bɛ se ka ɲɛ, welding total cost bɛ se ka dɔgɔya, ani welding efficiency bɛ se ka ɲɛ.
Sisan, izini caman na, argon gazi ɲagaminenw kɛra ka caya, nka k’a sababu kɛ sababu suguya caman ye, jamana kɔnɔ baarakɛda fanba bɛ 80% argon AR+20% gazi ɲuman kɛ. Baara caman na, gazi min bɛ lakana, o tɛ baara kɛ ka ɲɛ. O la, gazi ɲuman sugandili ye tiɲɛ na fɛɛrɛ nɔgɔman ye min bɛ se ka kɛ ka fɛn dilannenw maracogo ɲɛ ka taa a fɛ welding baarakɛyɔrɔ la ɲɛtaa sira kan. Gazi min ka fisa ni gazi ye, o sugandicogo min nafa ka bon kosɛbɛ, o ye ka welding wajibiyalenw yɛrɛ dafa ka se hakɛ bɛɛ ma. Ka fara o kan, gazi bɔli hakɛ bɛnnen ye fɛn ye min ka kan ka kɛ walasa ka welding quality sɔrɔ, ani ka caya walima ka caya kojugu walima ka caya kojugu, o tɛ nafa sɔrɔ welding na.
