Umatshini wokuwelda nge-laser usebenzisa i-laser pulse enamandla aphezulu ukwenza ubushushu kwiindawo ezincinci zezinto ezicutshungulwayo. Amandla aya kuthi emva koko adluliselwe ngaphakathi kwezinto ngokudluliselwa kobushushu, emva koko izinto ziya kunyibilika ukuze zenze ichibi elithile elinyibilikisiweyo ukuze kufezekiswe injongo yokunyibilika.
Umatshini wokuwelda nge-laser ngumatshini oqhelekileyo wokucubungula kwicandelo leshishini. Ngokwendlela yokusebenza, umatshini wokuwelda nge-laser unokwahlulwahlulwa ube ngumatshini wokuwelda nge-laser ozenzekelayo, umatshini wokuwelda kwindawo ye-laser, umatshini wokuwelda nge-fiber laser njalo njalo.
Kukho iintlobo ezininzi zezinto ezinokwenziwa ngumatshini wokuwelda nge-laser. Nazi ezimbalwa:
1. Intsimbi ye-die
Umatshini wokuwelda nge-lase ungasebenza kwintsimbi yedayi kwezi ntlobo zilandelayo: S136, SKD-11, NAK80, 8407, 718, 738, H13, P20, W302,2344 njalo njalo. Impembelelo yokuwelda kwezi ntsimbi zedayi ilungile kakhulu.
2. Intsimbi yekhabhoni
Ekubeni isantya sokufudumeza kunye nesantya sokuphola komatshini wokuwelda nge-laser zikhawuleza kakhulu xa usebenza, ukuqhekeka kwe-welding kunye novakalelo lwesithuba kuya kwanda njengoko ipesenti yekhabhoni isanda. Intsimbi yekhabhoni ephakathi kunye nentsimbi ye-alloy eqhelekileyo zombini ziintsimbi zekhabhoni ezifanelekileyo ukusebenza kuzo, kodwa zifuna ukufudumeza kwangaphambili kunye nonyango emva kokuwelda ukuze kuthintelwe ukuqhekeka kwe-welding.
3. Intsimbi engatyiwayo
Xa ithelekiswa nentsimbi yekhabhoni, intsimbi engatyiwayo ine-conductivity factor ephantsi kunye nesantya esiphezulu sokufunxa amandla. Ukusebenzisa umatshini wokuwelda we-laser onamandla amancinci ukuwelda ipleyiti yentsimbi engatyiwayo ebhityileyo kunokufezekisa umbono olungileyo wokuwelda kunye ne-weld joint egudileyo ngaphandle kwe-bubble kunye ne-gap.
4. I-Copper kunye ne-copper alloy
Kucetyiswa ukuba kusetyenziswe umatshini wokuwelda welaser ophakathi kakhulu ukuze kusetyenzwe kwi-copper kunye ne-copper alloy kuba kunzima ukuzifikelela ngokupheleleyo. Uxinzelelo olushushu, amaqamza kunye noxinzelelo lokuwelda ziingxaki eziqhelekileyo emva kokuwelda.
5. Iplastiki
Iiplastiki eziqhelekileyo ezisetyenziswa ngumatshini wokuwelda nge-laser ziquka i-PP, i-PS, i-PC, i-ABS, i-PA, i-PMMA, i-POM, i-PET kunye ne-PBT. Nangona kunjalo, umatshini wokuwelda nge-laser awusebenzi ngqo kwiplastiki kwaye abasebenzisi kufuneka bongeze i-carbon black kwizinto ezisisiseko ukuze amandla aneleyo afunxwe njengoko iplastiki inesantya esiphantsi sokungena nge-laser.
Ngelixa umatshini wokuwelda nge-laser usebenza, umthombo we-laser ngaphakathi udla ngokuvelisa ubushushu obugqithisileyo. Ukuba olu hlobo lobushushu alunakuthatyathwa ngexesha, umgangatho wokuwelda uya kuchaphazeleka, okanye okubi nangakumbi, okukhokelela ekuvaleni komatshini wokuwelda nge-laser yonke. Kodwa ungakhathazeki. I-S&A Teyu inako ukubonelela ngezisombululo zokupholisa nge-laser zobungcali kwiintlobo ezahlukeneyo zoomatshini bowelda nge-laser abane-±0.1℃,±0.2℃,±0.3℃,±0.5℃ kunye nozinzo lobushushu lwe-±1℃ ukuze kukhethwe.
