Oomatshini bokuwelda be-laser bentsimbi abaphuhliswe kwaye baveliswa yinkampani yethu basebenzisa imingxunya yokugxila ye-ceramic, enganyangekiyo kukugqwala, enganyangekiyo kubushushu obuphezulu, kwaye inikezela ngokusebenza kakuhle kokuguqula i-photoelectric. I-focused cavity kunye ne-xenon lamp zinobomi benkonzo obungaphezulu kwe-8 yezigidi zeerandi. Imveliso yegesi ekhuselayo iqinisekisa ukuwelda okumnandi ngaphandle kwe-oxidation okanye i-discolor. Umatshini unako ukusebenza ngokuqhubekayo iiyure ezingama-24/7 kunye nokusebenza okuzinzileyo iyonke.

Inzuzo yokuwelda nge-laser yokufudumeza kwindawo encinci kuyenza isetyenziswe kakhulu kumashishini afana nobucwebe, iibhetri, kunye nezixhobo zefowuni eziphathwayo.

Ukuwelda nge-laser kubonakaliswa ngamandla aphezulu okuwelda, isantya esikhawulezayo, kunye namazinga aphantsi okulahlwa, nto leyo eyenza ukuba isetyenziswe kakhulu kwimveliso yanamhlanje. Kwimveliso yobucwebe, ineenzuzo ezahlukeneyo ngaphezu kobuchwepheshe bendabuko bokuwelda:

1. Isantya Esikhawulezayo, Amandla Aphezulu, Ukuguquka Okuncinci, Akukho Kulula Emva Kokuwelda okanye Ukucoca Isizathu esiphambili sokuba abavelisi bezinto zokuhombisa bamkele ukuwelda nge-laser kukukhawuleza kwayo kunye nokuguquguquka okuncinci, okususa isidingo sokulungisa nokucoca emva kokuwelda. Nangona ukuwelda nge-laser kukhawuleza kune-flame welding yendabuko, abaqhubi badla ngokubamba izinto zokusebenza ngesandla okanye basebenzise izixhobo, bewelda into enye ngexesha. Uninzi lweendawo zokusebenza zokuwelda nge-laser zincinci, zinciphisa amandla okucubungula ibhetshi kwaye zinyusa ixesha lokuwelda kancinci. Nangona kunjalo, ixesha eligcinwe ekucoceni lihlawulela ngokupheleleyo oku. Ukuwelda nge-laser kungenziwa phantsi kokhuseleko lwegesi olungasebenziyo, kungashiyi mabala omlilo kwiimveliso—kususwe isidingo sokuhamba ngexesha lokuwelda kunye nokucocwa kwe-asidi emva koko. Lilonke, ukuwelda nge-laser kubonelela ngokusebenza okuphezulu kwemveliso.

2.Ifanelekile kwiiWorkpieces ezichanekileyo, Ukuqinisekisa uMgangatho oQhubekekayo

Umqadi welaser ungajoliswa kwindawo encinci ukuze ubekwe ngokuchanekileyo, nto leyo eyenza ukuba ifaneleke kakhulu kwimveliso ezenzekelayo ngobuninzi. Ayiphuculi nje kuphela ukusebenza kakuhle kodwa ikwanciphisa indawo echaphazeleka bubushushu kwaye iqinisekisa ukuwelda okungenangcoliseko, iphucula kakhulu umgangatho wokuwelda kwaye inciphise amazinga okulahlwa. Umzekelo, ubucwebe be-14K alloy (58% Au, 2% Ag) obufakwe nge-flame welding bunokuba namava okuwelda kwe-Ag, kunciphisa ubunzima obupheleleyo ukusuka kwi-Hv=145 malunga nesiqingatha—okubangela ukuqhekeka ukuba kuwiswe ukusuka kubude besinqe. Ngokwahlukileyo koko, ukuwelda kwelaser okunamandla aphantsi, okukhawulezayo kugxila kubushushu, kuthintela ukuwelda kwe-workpiece kunye nokugcina amandla esakhiwo.

3. Ukulungelelaniswa Okuphezulu Kokuhlanganisa, Okuvumela Iinkqubo Zokuvelisa Ubucwebe Obutsha Ukungeniswa kokuwelda nge-laser kwishishini lobucwebe kutshintshe indlela yokucinga yoyilo lwendabuko. Kuvumela ukudalwa kwezitayile zobucwebe ezikhethekileyo ezazinzima ukuzifezekisa okanye ezingaphumeleli ukuhlangabezana neemfuno zomgangatho nge-welding yendabuko. Ukuwelda nge-laser kusebenza kwindawo emxinwa, okwenza kube lula ukuwelda kwezinto ezahlukeneyo ze-alloy ngaphandle kokuxubana—okuvumela umbala okhawulezileyo okanye utshintsho lwesakhiwo phakathi kwezinto. Indawo yayo yokusebenza emxinwa iyahlula kwi-welding yendabuko ngokubhekiselele ekumanzini, ukuthembeka kwamalungu, kunye nobukhulu bengqolowa kwindawo echaphazelekileyo bubushushu.

4. Ukungaguquguquki kunye nozinzo oluhle kakhulu

Ukuwelda nge-laser kudla ngokuwelda ngokuthe ngqo ngokunyibilikisa izinto zokusebenza ngaphandle kwesidingo seentsimbi zokuzalisa okanye ukujika.

5. Yenza kube lula ukulungisa izinto zomsebenzi

Ingalungisa isinyithi kufutshane namatye anqabileyo, isuse imingxunya kwi-castings, kwaye idibanise iindawo ezikufutshane ne-0.2mm kwizinto ezintsonkothileyo nezinobushushu (umz., iihinges, iihook, iikliphu, kunye nokuseta).

6. Ilungele okusingqongileyo

Akukho mfuneko yee-solder, flux, okanye iikhemikhali zokucoca ngexesha lokuwelda nge-laser, nto leyo ephelisa iingxaki zokulahla inkunkuma.

7.Igcina Izinto zeSinyithi

Ukuwelda kwendabuko kufuna ubuncinci bentsimbi ubukhulu be-0.2mm, ngelixa ukuwelda nge-laser kunciphisa oku ukuya kwi-0.1mm—kunciphisa ubunzima bezinto zokuhombisa ngama-35% ~ 40%, nto leyo ebaluleke kakhulu kwiimveliso ezenziwe ngombane. Ukuwelda nge-laser kusindisa iintsimbi ezixabisekileyo kunye ne-solder, kwaye kususa imfuneko yeentlobo ezahlukeneyo ze-solder kwiindawo ezininzi zokuwelda.

8. Iimpawu zoMshini oPhambili

Oomatshini bokuwelda be-laser bezinto zokuhombisa ezisetyenziswa kakhulu kushishino banamandla amancinci, nto leyo eqinisekisa ukhuseleko oluphezulu. Banoyilo oluncinci noluphathekayo, oluvumela abaqhubi ukuba basebenze kamnandi xa behleli phantsi.
Oomatshini bokuwelda be-laser abaqhelekileyoIngashisela uninzi lweentsimbi kunye nee-alloys ngokukhawuleza, ngokuthembekileyo, nangokuchanekileyo, nangona ukusebenza kakuhle kuxhomekeke kakhulu kwiimpawu zezinto ekujoliswe kuzo. Ukuhlanganiswa okuqhubekayo okanye ukulungiswa kwe-casting kungagqitywa nge-laser pulses enye okanye ezingaphezulu phantsi kolawulo olubonakalayo, kunye ne-pulse nganye ehlala i-1 ~ 20ms. Ii-Stereomicroscopes kunye nokulungelelaniswa kwe-crosshair kwenza kube lula ukubeka iindawo zokushisela ngokuchanekileyo, okuvumela ukulungiswa okucokisekileyo kwendawo yokusebenza ngaphakathi kwendawo yokubona. Ukushisela kudla ngokwenziwa kwiimeko zomoya; ukufaka umoya okanye igesi engasebenziyo kwindawo yokusebenza kunokubonelela ngokupholisa, kwaye igesi engasebenziyo iphucula ngakumbi umgangatho wokushisela i-alloy.

9. Impembelelo yezixhobo ze-Alloy kwi-Laser Welding Performance
Izinto ezahlukeneyo ze-alloy zivelisa iziphumo ezahlukeneyo ze-laser welding. Phantsi kweeparamitha ezifanayo zomatshini kunye nokufakwa kobushushu be-pulse, umahluko kumlinganiselo wamandla obushushu afunxwayo (ngokuthelekiswa nokubonakaliswa) ngumphezulu we-alloy ukhokelela kwiziphumo ezahlukeneyo zokunyibilika nge-pulse nganye. Izinto eziphambili ezinefuthe ziquka amandla obushushu (ukusuka kubushushu begumbi ukuya kwinqanaba lokunyibilika), indawo yokunyibilika, ubushushu obufihlakeleyo bokudibana, kunye nokuqhuba kobushushu. Utshintsho kwezi mpawu kuzo zonke izixhobo luchaphazela kakhulu amandla afunekayo ukuze kufakwe i-welding ngempumelelo—ukufunxwa kobushushu bomphezulu okwaneleyo kubalulekile ukuze kufakwe i-welding ngempumelelo.
