Ubungakanani bobubanzi be-laser core buya kuchaphazela ukulahleka kokudluliselwa kunye nokusasazwa kobuninzi bamandla bokukhanya. Ukukhetha okufanelekileyo kobubanzi be-core kubaluleke kakhulu. Ububanzi be-core obuninzi buya kukhokelela ekuphazamisekeni kwendlela kunye nokusasazeka kokudluliselwa kwe-laser, okuchaphazela umgangatho we-beam kunye nokuchaneka kokugxila. Ububanzi be-core bukhulu kakhulu buya kubangela Ulungelelwaniso lobuninzi bamandla okukhanya kwi-fiber ye-single-mode luba mandundu, nto leyo engayi kuncedayo ekuhanjiswenii-laser enamandla aphezulu.
1. Iingenelo kunye nokusetyenziswa kwe-laser ezincinci ze-core diameter (<100um)
Izixhobo ezibonisa ukukhanya okuphezulu: i-aluminium, ubhedu, intsimbi engatyiwayo, i-nickel, i-molybdenum, njl.njl.;
(Ifoto efutshane)1）Izixhobo ezikhanyayo kakhulu kufuneka zikhethe i-laser encinci enobubanzi obuphakathi. Umqadi we-laser oxineneyo onamandla aphezulu usetyenziselwa ukufudumeza ngokukhawuleza izinto zibe kwimeko yolwelo okanye yokufuma, nto leyo ephucula izinga lokufunxwa kwe-laser yezinto kwaye ifezekise ukucutshungulwa okusebenzayo nokukhawulezileyo. Ukukhetha i-laser enobubanzi obuphakathi obukhulu kunokukhokelela ngokulula ekukhanyeni okuphezulu. , okukhokelela ekuwelding okubonakalayo nasekutshisweni kwe-laser;
Izinto ezibuthathaka kwiingcangca: i-nickel, i-nickel-plated copper, i-aluminium, intsimbi engatyiwayo, i-titanium alloy, njl.
Le nto ifuna ulawulo olungqongqo lwendawo echaphazelekileyo bubushushu kunye nedama elincinci elinyibilikayo, ngoko ke kufanelekile ukukhetha i-laser encinci yobubanzi obuphakathi;
Ukucubungula nge-laser ekhawulezayo:
(Ifoto efutshane)3）Ukuwelda okunzulu kufuna ukucutshungulwa nge-laser ekhawulezayo, kwaye kuyimfuneko ukukhetha i-laser enamandla amaninzi ukuqinisekisa ukuba amandla omgca anele ukunyibilikisa izinto ngesantya esiphezulu, ingakumbi ukuwelda kwelaphu, ukuwelda kwe-penetration, njl.njl., ezifuna ubunzulu bokungena obuphezulu. Kungcono ukukhetha i-laser encinci enobubanzi obuphakathi efanelekileyo.
2. Iingenelo kunye nokusetyenziswa kwe-laser ezinkulu ezinobubanzi obuphambili (>100um)
Ububanzi obukhulu be-core kunye nendawo enkulu, indawo enkulu yokugubungela ubushushu, indawo ebanzi yesenzo, kunye nokunyibilika okuncinci kuphela komphezulu wezinto ezibonakalayo, okufanelekileyo kakhulu kwizicelo ze-laser cladding, i-laser remelting, i-laser annealing, i-laser hardening, njl. Kule mimandla, indawo enkulu yokukhanya ithetha ukusebenza kakuhle kwemveliso kunye neziphene eziphantsi (i-thermal conductive welding ayinazo phantse iziphene).
Ngemimiselo yokubaukuwelda, indawo enkulu isetyenziselwa ikakhuluukuwelda okudityanisiweyo, esetyenziselwa ukuxubana nge-laser encinci yobubanzi be-core: indawo enkulu yenza umphezulu wezinto unyibilike kancinci, uguquka ukusuka kwinto eqinileyo ukuya kulwelo, nto leyo ephucula kakhulu izinga lokufunxwa kwezinto ukuya kwi-laser, ize isebenzise i-core encinci Kule nkqubo, ngenxa yokufudumeza kwangaphambili indawo enkulu, emva kokucubungula, kunye nobushushu obukhulu obunikwa ichibi elinyibilikisiweyo, izinto azinazo iimpazamo zokuqhekeka ezibangelwa kukufudumala ngokukhawuleza kunye nokupholisa ngokukhawuleza. Ingenza ukubonakala kwe-weld kube lula kwaye kufumane ukusasazeka okuphantsi kunesisombululo se-laser enye.
