Industriw ka fɛn dilanni na, welding jogo bɛ nɔ bila fɛnw kɛcogo la ani u si hakɛ la.Inverter de fréquence moyenne Spot Welders (Spot Welders) ka baara kɛ ni a yebɛ baara kɛ ni u ye kosɛbɛ k’a sababu kɛ u ka se ka soudure baarakɛcogo ɲuman ni sabatilen ye, nka ni soudure joint métallographie bɛ se ka kɛ, o bɛ ɲini hali bi ka sɛgɛsɛgɛli kɛ ni baarakɛlaw ka sɛgɛsɛgɛli ye. Nin barokun in bɛ nɛgɛko sɛgɛsɛgɛli yɔrɔ kolomaw sɛgɛsɛgɛ welda minnu bɛ kɛ Medium Frequency Inverter Spot Welders fɛ.
1. Nɛgɛsɛgɛsɛgɛli kuntilenna jɔnjɔnw
Nɛgɛsɛgɛsɛgɛli laɲini ye ka mikrosɔrɔcogo, sumanw tilatilali, ani nafamafɛnw jateminɛ welda yɔrɔ la. Medium Frequency Inverter Spot Welders fɛ, u ka welda cogoyaw (misali la, funteni misɛnnin-yɔrɔ min bɛ nɔ bila, fanga caman) b’a jira ko sɛgɛsɛgɛli ka kan ka sinsin nin taamasiyɛn ninnu kan:
- Sumanw nɔgɔyali hakɛ Nugget Zone kɔnɔ: Inverter Frequency Medium Spot Welders bɛ funteni teliya sɔrɔ 1000Hz inverter current fɛ. A ka c’a la, nugget zone suman hakɛ bɛ kɔlɔsi 5-15μm cɛ, o ka fisa ni AC welding laadala 20-30μm ye, o bɛ dɔ bɔ bɔgɔbɔgɔli farati la.
- Funteni-Zon min bɛ nɔ bila: Medium Frequency Inverter Spot Welders ka HAZ caman na, o tɛ tɛmɛ 0,5mm kan. Kɔlɔsili mikroskɔpi ka kan ka kɛ walasa ka suman dancɛ oksidan walima jeninida lajɛ.
- Weld Joint Strength: Aw bɛ a sɛgɛsɛgɛ ni tensile testing ye ni weld shear strength bɛ se ka tɛmɛ 80% kan fɛn in nafa teori la.
2. Fɛn minnu ka kan ka kɛ nɛgɛko sɛgɛsɛgɛli la
- Misali labɛncogo: Misali kɛlen kɔfɛ, joginda min dilannen don ni solda ye, o ka kan ka sigi, ka a sɔgɔ, ka a sɔgɔ walasa a ka kɛ yɔrɔ ye min tɛ sɔgɔsɔgɔ{0}}.
- Kɔlɔsili ni mikroskɔpi ye : Aw bɛ baara kɛ ni nɛgɛko mikroskɔpu ye ni a bonya ye 100-500x ye walasa ka sumanw cogoya kɔlɔsi nugu yɔrɔ la, funteni bɛ yɔrɔ min na, ani nɛgɛ basigilen na. Misali la, nɛgɛ inox weld nuggets minnu bɛ bɔ Medium Frequency Inverter Spot Welder la, olu ka kan ka kisɛw jira minnu bɛ kɛ ɲɔgɔn fɛ, ni u ma fara walima ni u tɛ ni fɛnba ye.
- Chemical Etching and Analysis : Aw bɛ baara kɛ ni electrolytic etching ye walasa ka sumanw dancɛw jira ani ka sumanw sɛnɛcogo ɲuman jateminɛ ka taa a fɛ. Mobili yɔrɔw dilannikɛla dɔ ka sɛgɛsɛgɛliw y’a jira ko nɛgɛ 304 minnu bɛ kɛ ni nɛgɛ ye min tɛ sɔgɔ, minnu bɔra Medium Frequency Inverter Spot Welder la, olu ye suman hakɛ kelen sɔrɔ 95%, o ka fisa kosɛbɛ ni laadala minɛnw ye.
3. Inverter Spot Welders (Inverter Spot Welders) ka nafaw sɔrɔli fɛɛrɛko siratigɛ la
- Funteni kɔlɔsili: Inverter Spot min bɛ wele ko Medium Frequency Inverter Spot Welders bɛ baara kɛ ni pulse discharge (sekɔndi 0,1-0,3) ye min ka bon-frequency (sekɔndi 0,1-0,3) walasa ka funteni caman lajɛ welda yɔrɔ la, o bɛ dɔ bɔ sumanw sɔgɔli la min bɛ sɔrɔ nɛgɛ basigilenw sumaya kojugu fɛ.
- Paramɛtiriw ladilanni hakilitigi : Sensɛriw minnu bɛ don- kɔnɔ, olu bɛ kuran ni degun kɔlɔsi waati yɛrɛ la, ka u yɛrɛ tanga fiɲɛw ma minnu bɛ sɔrɔ paramɛtiriw jiginni fɛ welda waati. Misali la, ni aliminiyɔmu sɔgɔlen bɛ solda, Medium Frequency Inverter Spot Welder bɛ se ka sɔgɔsɔgɔninjɛ hakɛ kɔlɔsi min bɛ 1% duguma.
- Taabolo sabatili : Dilancogo modululenw ani nɛnɛ kɛcogo ɲumanw (fiɲɛ + ji) b’a to welda jogo bɛ tɛmɛ 98% kan baara jan kɛtuma na.
4. Sɛgɛsɛgɛli kɛcogo min bɛ kɛ ka kɛɲɛ ni waleyali ye
Enerji batiri baarakɛyɔrɔ kura dɔ ye baara kɛ ni Medium Frequency Inverter Spot Welder ye walasa ka tab welding kɛ. Nɛgɛso sɛgɛsɛgɛli jaabiw y’a jira ko:
- Welda funteni-yɔrɔ min nɔ bilala yɔrɔ la, o bonya tun ye milimɛtɛrɛ 0,45 ye, o bɛ se ka kɛ sababu ye ka izini sariyaw dafa ( A ka dɔgɔ ni milimɛtɛrɛ 0,6 ye walima a bɛ bɛn milimɛtɛrɛ 0,6 ma).
- Weld shear strength in tensile tests sera 250MPa ma, o tɛmɛna dilancogo wajibiyalenw kan ( A ka bon walima a bɛ bɛn 200MPa ma).
- 1000 la, 2 dɔrɔn de tun bɛ ni porosité misɛnnin ye, o kɛra sababu ye ka tɛmɛsira 99,8% sɔrɔ.
Kuncɛli
Ka tɛmɛn-frequency current ni hakilitigiya kɔrɔsili fɛɛrɛ fɛ,Inverter de fréquence moyenne Spot Welders (Spot Welders) ka baara kɛ ni a yeka jogindaw weldalenw ka mikroskɔpi jogo ɲɛ kosɛbɛ. Nɛgɛsɛgɛsɛgɛli tɛ welding kɛcogo sɛgɛsɛgɛli dɔrɔn ye, nka a ye jɛɲɔgɔnya jɔnjɔn ye fana walasa ka fɛn dilannenw dannaya sabati. Fɛn dilanni hakilitigiw ka taabolo kɔrɔ, nɛgɛko sɛgɛsɛgɛli fɛɛrɛw dɔnni Medium Frequency Inverter Spot Welder welds kama, o bɛna kɛ seko jɔnjɔn ye baarakɛda minnu bolo walasa ka welding taabolo ɲɛ ani ka ɲɔgɔndan sabati.
