Ịhọrọ oke ọsọ gas na-ezighi ezi, ma ọ dị oke elu ma ọ bụ dị ala, nwere ike ibute mmụba nke oxidation nke njikọta weld. Ọ nwekwara ike ịkpata nnukwu nsogbu na ígwè a gbazere agbaze, na-ebute ọdịda ma ọ bụ nhazi na-adịghị mma nke njikọta weld.
4. Mmụba ojiji laser
Itinye gas nchebe nke ọma nwere ike ibelata mmetụta nchebe nke plume vapor metal ma ọ bụ ígwé ojii plasma na laser nke ọma, si otú a na-eme ka arụmọrụ laser dịkwuo elu.
4. Nchedo na-ezughị ezu ma ọ bụ Mmetụta Ọjọọ
Ịhọrọ ụzọ ntinye gas na-ezighi ezi nwere ike ibute nchekwa zuru oke nke njikọta weld ma ọ bụ ọbụna nwee mmetụta ọjọọ na nhazi nke njikọta weld.
5. Mbelata nke Weld Porosity
Itinye gas nchebe nke ọma nwere ike ibelata mmepụta nke oghere gas na njikọta weld nke ọma. Site n'ịhọrọ ụdị gas kwesịrị ekwesị, ọnụego mmiri, na usoro mmeghe, enwere ike nweta nsonaazụ kacha mma.
5. Mmetụta na Omimi nke Weld
Ntinye gas nchebe nwere ike inwe mmetụta ụfọdụ na omimi nke weld ahụ, ọkachasị na weld dị gịrịgịrị, ebe ọ na-ebelata omimi weld ahụ.
Ụdị Gas Nchebe Dị Iche Iche
Gas nchebe a na-ejikarị eme ihe n'ịgbado ọkụ laser bụ nitrogen (N2), argon (Ar), na helium (He). Gas ndị a nwere ihe dị iche iche nke anụ ahụ na kemịkalụ, nke na-ebute mmetụta dị iche iche na njikọta weld.
1. Nitrogen (N2)
N2 nwere ike ionization dị mma, dị elu karịa Ar ma dị ala karịa He. N'okpuru ọrụ nke laser ahụ, ọ na-agbanwe ion ruo n'ókè dị mma, na-ebelata mmepụta nke ígwé ojii plasma nke ọma ma na-eme ka ojiji laser dịkwuo elu. Agbanyeghị, nitrogen nwere ike imeghachi omume na kemịkalụ na alloys aluminum na carbon steel na okpomọkụ ụfọdụ, na-emepụta nitrides. Nke a nwere ike ime ka ike gbawaa ma belata ike nke njikọta weld, na-emetụta ihe onwunwe ya n'ụzọ na-adịghị mma. Ya mere, a naghị atụ aro iji nitrogen dị ka gas nchebe maka alloys aluminum na carbon steel welds. N'aka nke ọzọ, nitrogen nwere ike imeghachi omume na ígwè anaghị agba nchara, na-emepụta nitrides nke na-eme ka ike nke njikọ weld dịkwuo mma. Ya mere, enwere ike iji nitrogen dị ka gas nchebe maka ịgbado ígwè anaghị agba nchara.
2. Mmanụ Argon (Ar)
Gas Argon nwere ike ionization kacha ala, nke na-ebute oke ionization dị elu n'okpuru ọrụ laser. Nke a adịghị mma maka ijikwa nhazi nke ígwé ojii plasma ma nwee ike inwe mmetụta ụfọdụ na ojiji laser dị irè. Agbanyeghị, argon nwere obere mmeghachi omume ma ọ gaghị ekwe omume ịnweta mmeghachi omume kemịkalụ na ọla nkịtị. Na mgbakwunye, argon dị ọnụ ala. Ọzọkwa, n'ihi oke njupụta ya, argon na-emikpu n'elu ọdọ mmiri weld, na-enye nchebe ka mma maka ọdọ mmiri weld. Ya mere, enwere ike iji ya dị ka gas nchebe nkịtị.
3. Gas Helium (He)
Gas helium nwere ike ionization kachasị elu, nke na-eduga na obere ọkwa ionization n'okpuru ọrụ laser. Ọ na-enye ohere maka njikwa ka mma nke nhazi igwe ojii plasma, lasers nwekwara ike imekọrịta ihe nke ọma na ọla. Ọzọkwa, helium nwere obere mmeghachi omume ma ọ naghị anabata mmeghachi omume kemịkalụ ngwa ngwa na ọla, na-eme ka ọ bụrụ gas dị mma maka nchekwa weld. Agbanyeghị, ọnụ ahịa helium dị elu, yabụ a naghị eji ya eme ihe n'ọtụtụ mmepụta nke ngwaahịa. A na-ejikarị ya eme ihe na nyocha sayensị ma ọ bụ maka ngwaahịa ndị bara uru dị elu.
