Ka hona, ho latela litšoaneleho tse fapaneng tsa sebaka sa welding, ts'ebetso ea welding e hlahisitse welding ea laser filler, laser brazing, dual-beam laser welding, laser composite welding, jj.
Laser Wire Tlatsa Welding
Ts'ebetsong ea laser welding ea aluminium, titanium le lialloys tsa koporo, ka lebaka la ho monya ho tlase ha leseli la laser (<10%) lisebelisoa tsena, plasma ea foto e na le tšireletso e itseng ea lebone la laser, kahoo ho bonolo ho theha spatter le ho lebisa molokong oa mefokolo joalo ka porosity le mapetsong. Ho phaella moo, boleng ba tjheseletsa bo boetse bo ameha ha lekhalo pakeng tsa li-workpieces le leholo ho feta bophara ba letheba nakong ea sputtering e tšesaane ea poleiti.
Ho rarolla mathata a ka holimo, sephetho se betere sa welding se ka fumanoa ka ho sebelisa mokhoa oa ho tlatsa. Filler e ka ba terata kapa phofo, kapa ho ka sebelisoa mokhoa o hlophisitsoeng esale pele. Ka lebaka la sebaka se senyenyane se tsepamisitsoeng, weld e ba moqotetsane 'me e na le sebopeho sa convex hanyenyane ka holim'a metsi ka mor'a hore ho sebelisoe thepa ea ho tlatsa.
Khabiso ea laser
Ho fapana le fusion welding, e qhibilihisang likarolo tse peli tse cheselitsoeng ka nako e le 'ngoe, brazing e eketsa thepa ea ho tlatsa e nang le ntlha e tlase ea ho qhibiliha ho feta thepa ea motheo ho ea holim'a weld, e qhibilihisa thepa ea ho tlatsa ho tlatsa lekhalo ka mocheso o tlase ho feta ho qhibiliha ha thepa ea motheo. ntlha 'me e phahame ho feta ntlha ea ho qhibiliha ha thepa ea ho tlatsa, ebe e kopana ho etsa weld e tiileng.
Brazing e loketse lisebelisoa tsa microelectronic tse sa utloisiseng mocheso, lipoleiti tse tšesaane le lisebelisoa tsa tšepe tse sa tsitsang.
Ho feta moo, e ka aroloa ka ho eketsehileng e le brazing e bonolo (<450 ° C) le brazing e thata (> 450 ° C) ho itšetlehile ka mocheso oo thepa ea brazing e futhumatsoang ka eona.
Ho tjheseletsa Laser ka Dual Beam
Dual-beam welding e lumella taolo e bonolo le e bonolo ea nako ea mahlaseli a laser le boemo, kahoo e lokisa kabo ea matla.
E sebelisoa haholo-holo bakeng sa welding ea laser ea aluminium le magnesium alloys, splice le lap plate welding bakeng sa likoloi, laser brazing le deep fusion welding.

3, sebaka sa ts'ebetso sa laser welding se nyane, ho bonolo ho baka ho se tsamaisane hantle ha kou ea welding, ha ts'ebetso ea mocheso oa arc e le kholo, e ka khonangfokotsa ho se tsamaisane hantle ha boema-kepe ba tjheseletsa. Ka nako e tšoanang, theboleng ba welding le katleho ea arc e ntlafalitsoeka lebaka la ho tsepamisa maikutlo le ho tataisa ha lebone la laser holim'a arc.
4, laser welding e nang le mocheso o phahameng o phahameng, sebaka se seholo se anngoeng ke mocheso, ho pholisa ka potlako le lebelo la ho tiisa, ho bonolo ho hlahisa mapetsong le li-pores; ha sebaka sa arc se amehileng ke mocheso se le senyane, se ka fokotsang mocheso oa mocheso, ho pholisa, lebelo la ho tiisa,e ka fokotsa le ho felisa moloko oa li-pores le mapetsong.
Ho na le mefuta e 'meli e tloaelehileng ea laser-arc composite welding: laser-TIG composite welding (joalokaha ho bontšitsoe ka tlase) le laser-MIG composite welding.
Ho boetse ho na le mefuta e meng ea tjheseletsa e kang laser le plasma arc, laser le inductive heat source compound welding.
