1. Umgaqo wokusebenza kunye neemeko zesicelo eziqhelekileyo zomatshini we-laser welding welding
Umatshini wokuwelda we-laser ophathwayo luhlobo lwezixhobo zokuwelda usebenzisa ubuchwepheshe belaser. Iqukethe i-laser, i-optical system, itotshi ye-welding, njl., enokuthi igxininise i-laser beam kumphezulu we-workpiece kwaye ivelise ubushushu obuphezulu bamandla, ngaloo ndlela iqonda ukunyibilika ngokukhawuleza kunye ne-welding. Xa kuthelekiswa ne-arc welding yendabuko, i-laser welding ephathwayo ineenzuzo zokuchaneka okuphezulu, ukusebenza kakuhle okuphezulu, ukusebenza okulula kunye nomthungo omhle we-weld. Isetyenziswa kakhulu ekusetyenzweni kwesinyithi, ukusetyenzwa kweemveliso zombane, ukwenziwa kweemoto kunye namanye amashishini.
2. Inkcazo kunye nomsebenzi weentlobo zegesi zokukhusela
(1) Iintlobo kunye nokuqaliswa kweegesi zokukhusela
I-Helium: ibiza kakhulu, kodwa eyona nto isebenzayo, ivumela i-laser ukuba idlule ngaphandle kokuphazamiseka kwaye ngokuthe ngqo kumphezulu we-workpiece.
IArgon: Ixabiso eliphantsi, elixineneyo, ukhuseleko olungcono, umphezulu we-weldment ugudileyo kune-helium, kodwa uchaphazeleka kwi-ionization yesinyithi ye-plasma ephezulu yobushushu, iya kukhusela inxalenye ye-boam kwindawo yokusebenza, ukunciphisa amandla asebenzayo e-welding, isantya sokudibanisa kunye ubunzulu bokudibanisa buthintelekile.
Nitrogen: ngexabiso eliphantsi, kodwa ayifanelekanga kwiwelding yentsimbi engenasici.
(2) Indima yeegesi ezikhuselayo
1. Khusela i-workpiece kwinkqubo ye-welding i-oxidized, umatshini we-laser welding usebenzisa i-gas ekhuselayo, ukuseta igesi ekhuselayo, kwaye emva koko iphuma kwi-laser, inokuthintela umatshini we-laser welding kwinkqubo yokucubungula okuqhubekayo, i-pulse laser oxidation phenomenon.
2. Khusela i-lens egxininisekileyo kwi-metal vapor contamination kunye ne-liquid droplet sputtering, ngokukodwa i-welding ephezulu, kuba i-ejecta inamandla kakhulu, ngoko kuyimfuneko ukukhusela i-lens.
3. Iigesi ezikhuselayo zinokuphucula ngokufanelekileyo umgangatho we-weld, iigesi ezahlukeneyo zineempembelelo ezahlukeneyo ekuhambeni kwe-pool etyhidiweyo, ukumanzisa kunye nezinye iimpawu, ngaloo ndlela zichaphazela umgangatho wokubunjwa kwe-weld.
4. Igesi efanelekileyo yokukhusela inokuphucula ukuhanjiswa kobushushu, ukuphucula ukusetyenziswa kwamandla e-laser, ngaloo ndlela inyusa isantya se-welding.
Ngoko ke, kubaluleke kakhulu ukukhetha igesi ekhuselekileyo yokukhusela kwi-handheld laser welding. Izinto ezahlukeneyo, iinkqubo ze-welding, kunye neeparamitha zezixhobo zonke zinempembelelo ekukhetheni igesi yokukhusela. Kuphela ngokukhetha igesi efanelekileyo yokukhusela sinokuthi siphucule ukusebenza koomatshini bethu be-laser welding kwaye sifumane iziphumo eziphezulu ze-welding.
