Ukuwelda nge-laser yenye yezona zinto zibalulekileyo ekucutshungulweni kwezinto ze-laser. Ukuwelda nge-laser ngumqadi wamandla aphezulu njengomthombo wobushushu wohlobo oluthile lobuchwepheshe bokuwelda ngokuchaneka, obusetyenziswa ikakhulu ngumphezulu wobushushu we-laser beam wamandla aphezulu, ubushushu obuvela kumphezulu wezinto ukuya ekusasazekeni kwangaphakathi, ngokulungiswa kweparameters ze-laser pulse, ukuze izinto ezihambelanayo zinyibilike, zenze ichibi elithile elinyibilikisiweyo.
Umgaqo wokuwelda nge-laser ungahlulwahlulwa ube yi-heat conduction welding kunye ne-laser deep penetration welding. Ukuwelda nge-laser kusebenzisa amandla e-laser ukudibanisa izinto zezixhobo ezahlukeneyo, ubukhulu obahlukeneyo okanye iimilo ezahlukeneyo ukuhlangabezana neemfuno zokusebenza kwezinto kwiimeko ezahlukeneyo. Inokwenza ubunzima obuncinci, ulwakhiwo olungcono kunye nokusebenza kakuhle kwezixhobo.
Ngoko ke, zithini iingenelo zomatshini wokuwelda nge-laser kwicandelo lokuwelda ipleyiti encinci? Iingenelo zomatshini wokuwelda nge-laser kwicandelo lokuwelda ipleyiti encinci: izinto zentsimbi engagqwali zisetyenziswa kakhulu ekwenzeni iimveliso ezahlukeneyo ezigqityiweyo, phakathi kwazo ukuwelda kweshiti yentsimbi engagqwali kube yinkqubo ebalulekileyo kwinkqubo yemveliso neyokuvelisa. Kodwa ngenxa yeempawu zeshiti yentsimbi engagqwali ngokwayo, nayo yabangela ubunzima obuthile ekuwelda, kodwa yakha yaba yingxaki yokuwelda kwicandelo leshiti yentsimbi engagqwali. Ishiti yesinyithi engagqwali yokucubungula umatshini wokuwelda yendabuko inengxaki enkulu, ishiti yentsimbi engagqwali ngenxa yokuqhuba kwayo ubushushu incinci kakhulu, malunga nesinye kwisithathu sesinyithi esiqhelekileyo esiphantsi kwekhabhoni, inqanaba lokuthintela lincinci, ngoko ke kwinkqubo yokuwelda xa isiphumo sokufudumeza nokupholisa sendawo, siya kwenza uxinzelelo olungalinganiyo kunye noxinzelelo, ukucutheka okude kwe-weld kumda wangaphandle weshiti yentsimbi engagqwali kuvelisa uxinzelelo oluthile, Nje ukuba uxinzelelo lomatshini wokuwelda wendabuko lukhulu kakhulu, luya kubangela ukuguquguquka kwe-wavy ye-workpiece, okungachaphazeli kuphela inkangeleko kodwa kukwachaphazela nomgangatho we-workpiece. Ukongeza, kuya kubakho ingxaki yokutsha kakhulu nokutsha.
Imbonakalo yomatshini wokuwelda we-fiber laser iyisombulula kakuhle le ngxaki. Ukuwelda kwe-laser kusebenzisa i-laser pulse enamandla aphezulu ukufudumeza izinto kwindawo encinci. Amandla emitha ye-laser ayasasazeka ngaphakathi kwezinto ngokusebenzisa ukuhanjiswa kobushushu, kwaye izinto ziyanyibilika ukuze zenze ichibi elithile elinyibilikisiweyo.Umlinganiselo ophezulu wobubanzi bokuwelda, ububanzi obuncinci bokuwelda, indawo encinci echaphazeleka bubushushu, ukuguquguquka okuncinci, isantya sokwelda esikhawulezayo, ukuwelda okugudileyo nokuhle, akukho processing okanye processing elula emva kokuwelda, ukuwelda okusemgangathweni ophezulu, akukho porosity, ulawulo oluchanekileyo, indawo encinci yokugxila, ukuchaneka okuphezulu kokubeka, kulula ukuyiqonda ngokuzenzekelayo. Umatshini wokuwelda we-laser onezibonelelo ezininzi uthatha indawo ngokuthe ngcembe kwimarike yokuwelda yephepha yendabuko.
