1) gas si wotsɔ kpɔa ame ta ƒe gege ɖe eme le mɔ si mesɔ o nu ate ŋu ana weld ƒe ƒoƒo nyuie o;
2) gas ƒomevi si mesɔ o tiatia ate ŋu ana weld la nagbã, eye ate ŋu ana mɔ̃ɖaŋununya ƒe nɔnɔme siwo le weld la me hã naɖiɖi;
3) Gas ƒe ƒoƒo ƒe sisi ƒe agbɔsɔsɔ si mesɔ o tiatia ate ŋu ana weld oxidation si nu sẽ wu (eɖanye be sisi ƒe agbɔsɔsɔme lolo akpa alo le sue akpa o), eye ate ŋu ana hã be weld pool metal la naɖe fu na wo vevie le gotagome ŋusẽwo ta, si ana be weld mu alo iminen forming;
4) Gas dodo ƒe mɔnu si mesɔ o tiatia ana weld la nagaɖo ametakpɔkpɔ ƒe ŋusẽkpɔɖeamedzi gbɔ o alo le gɔmedzedzea me gɔ̃ hã la, ametakpɔkpɔ ƒe ŋusẽkpɔɖeamedzi aɖeke alo ŋusẽ gbegblẽ ɖe weld ƒe wɔwɔme dzi o;
5) Gas si kpɔa ame ta ƒe xɔxlɔ̃ akpɔ ŋusẽ aɖe ɖe weld ƒe gege ɖe eme dzi, vevietɔ ne wole plate tsɛwo ƒom la, aɖe weld ƒe gege ɖe eme dzi akpɔtɔ.
2. Gas si kpɔa ame ta ƒe ƒomeviwo .
Ametakpɔnu ya siwo wozãna zi geɖe hena laser welding koŋ dometɔ aɖewoe nye nitrogen, argon, kple helium, eye woƒe dzɔdzɔmenuwo kple atikewo ƒe nɔnɔmewo to vovo, eyata ŋusẽ si wòkpɔna ɖe weld dzi hã to vovo.
1) Nitrogen .
Ionization ŋusẽ si le nitrogen me la le titina, ekɔ wu argon tɔ, ebɔbɔ wu helium tɔ, eye ionization ƒe agbɔsɔsɔme le laser ƒe dɔwɔwɔ te nye mama dedie nu, si ate ŋu aɖe plasma alilikpo ƒe wɔwɔ dzi akpɔtɔ nyuie wu, si ana laser zazã ƒe agbɔsɔsɔ si wɔa dɔ nyuie nadzi ɖe edzi. Nitrogen ate ŋu awɔ atike kple aluminum alloy kple carbon steel le dzoxɔxɔ aɖe me be woawɔ nitrides, si ana weld ƒe brittleness nadzi ɖe edzi, aɖe sesẽme dzi akpɔtɔ, eye wòakpɔ ŋusẽ gbegblẽ geɖe ɖe weld ƒe ƒuƒoƒoa ƒe mɔ̃ɖaŋununya dzi, eyata womeɖo aɖaŋu be woazã nitrogen na aluminum alloy kple carbon steel welds hena takpɔkpɔ o.
Nitrogen si wowɔ to nitrogen kple gakpo si mexɔ dzo o ƒe dɔwɔwɔ me la ate ŋu ana weld ƒe ƒuƒoƒoa ƒe ŋusẽ nadzi ɖe edzi, si akpe ɖe weld la ƒe mɔ̃ɖaŋununya ŋu wòanyo ɖe edzi, ale be woate ŋu azã nitrogen abe akpoxɔnu gas ene ne wole gakpo si mexɔ dzo o la ƒom.
2) Argon .
Argon ƒe ionization ŋusẽ le sue ŋutɔ, eye ionization ƒe dzidzenu le kɔkɔm le laser ƒe dɔwɔwɔ te, si menyo na plasma alilikpowo ƒe wɔwɔme dzi ɖuɖu o eye wòakpɔ ŋusẽ aɖe ɖe laser zazã nyuie dzi. Gake dɔwɔwɔ le argon me medea ame dzi kura o eye esesẽna be woatsɔ ga siwo bɔ la akpe ɖe eŋu. Atike aɖe ƒe dɔwɔwɔ dzɔna, eye ga si wozãna ɖe argon ŋu la mesɔ gbɔ o. Tsɔ kpe ɖe eŋu la, argon ƒe kpekpeme le kɔkɔm, si sɔ be woanyrɔ ɖe weld-ta la tame, si ate ŋu akpɔ weld-ta la ta nyuie wu, ale be woate ŋu azãe abe akpoxɔnu ƒe gas zazã si bɔ ene.
3) Helium .
Helium ƒe ionization ŋusẽe nye esi kɔkɔ wu, eye ionization ƒe dzidzenu le sue ŋutɔ le laser ƒe dɔwɔwɔ te, si ate ŋu akpɔ ŋusẽ nyuie ɖe plasma alilikpo wɔwɔ dzi. Laser la ate ŋu awɔ dɔ ɖe ga dzi nyuie, eye helium ƒe dɔwɔwɔ le sue ŋutɔ, eye le nyateƒe me la, mewɔa dɔ kple ga le atikewo me o. , nye ya nyui aɖe ŋutɔ si wotsɔ blaa gas si wotsɔna kpɔa gae, gake helium ƒe asi sɔ gbɔ akpa, eye zi geɖe la, nusiwo wowɔna le agbɔsɔsɔ gã me mezãa gas sia o. Zi geɖe la, wozãa helium hena dzɔdzɔmeŋutinunya me numekuku alo atike siwo ƒe asixɔxɔ sɔ gbɔ ŋutɔ.
Ne nyabiase alo nuhiahiã aɖewo le asiwò ku ɖe . Laser welding pɔmpi wɔwɔ mɔ̃ tube mill wɔwɔ line , taflatse miɖe kuku, miate ŋu aƒo ka na mí hena kadodo.
