Lintlha tse amang laser welding
1. Matla a laser
Ho na le moeli oa sekhahla sa matla a laser ho welding ea laser. Ka tlas'a boleng bona, ho qhibiliha feela holim'a sefahleho sa workpiece ho etsahala, 'me botebo ba ho kenella ha bo teba haholo, ke hore, ho cheselletsa ho etsoa ka mokhoa o tsitsitseng oa mocheso oa mocheso; hang ha boleng bona bo fihletsoe kapa bo fetisitsoe, ho tla hlahisoa plasma, e leng pontšo ea Ka tsoelo-pele ea ho kenella ka hare ho tjheseletsa e tsitsitseng, botebo ba ho kenella bo tla eketseha haholo. Haeba matla a laser a le tlase ho feta monyako ona mme matla a matla a laser a le nyane, ho kenella ho sa lekaneng ho tla etsahala esita le ts'ebetso ea welding e ke ke ea tsitsa.
2. Lebelo la welding
Lebelo la welding le na le tšusumetso e kholo botebong ba ho kenella. Ho eketsa lebelo ho tla etsa hore ho phunyeha ho be tlaase, empa haeba lebelo le le tlaase haholo, ho tla baka ho qhibiliha ho feteletseng ha thepa le welding ea workpiece. Ka hona, ho na le lebelo le loketseng la tjheseletsa bakeng sa thepa e itseng e nang le matla a itseng a laser le botenya bo itseng, 'me ho kenella ho hoholo ho ka fumanoa ka lebelo le lekanang le lebelo.
3. Defocus palo
Ho boloka matla a lekaneng a matla, ho tsepamisa maikutlo ho bohlokoa. Sefofaneng se seng le se seng hole le laser focus, kabo ea matla a matla e batla e tšoana. Ho na le mekhoa e 'meli ea "defocus": "positive defocus" le negative defocus. Ha sefofane se shebileng se le ka holim'a workpiece, ke positive defocus, 'me ha e ka holim'a workpiece, ke negative defocus. Liphetoho tsa defocus li ama ka ho toba bophara le botebo ba weld.
4. Khase e sireletsang
Nakong ea ts'ebetso ea welding ea laser, likhase tse inert li atisa ho sebelisoa ho sireletsa letamo le qhibilihisitsoeng, empa lits'ebetsong tse ngata, likhase tse kang argon, naetrojene le helium li atisa ho sebelisoa bakeng sa tšireletso ho sireletsa workpiece ho oxidation nakong ea ts'ebetso ea ho tjheseletsa le ho fofa. plasma.
