I-Laser eqhubekayo ye-Laser
I-CW, isichazamazwi se- "akhronivu eqhubekayo," kusho amasistimu we-laser akwazi ukuhlinzeka ngemiphumela ye-laser engaphazamiseki ngesikhathi sokusebenza. Kuboniswa amandla abo okukhipha i-laser ngokuqhubekayo kuze kube yilapho umsebenzi uyaphela, ama-lasers e-CW ahlukaniswa amandla abo aphansi aphansi namandla aphezulu aphakathi ngokuqhathaniswa nezinye izinhlobo zama-lasers.
Izicelo ezibanzi kakhulu
Ngenxa yesici sabo sokuphuma esiqhubekayo, ama-CW lasers athola ukusetshenziswa okubanzi emikhakheni enjengokusika insimbi kanye nokushiswa kwethusi ne-aluminium, kubenza baphakathi kwezinhlobo ezivame kakhulu futhi ezisetshenziswa kabanzi zama-lasers. Amandla abo okuletha okuguqukayo futhi okungaguquki kwamandla okukhipha kube khulumela bona bagxile ekusetshenzisweni kokunemba kokucutshungulwa kanye nezimo zokukhiqiza eziningi.
Inqubo yokulungiswa kwamapharamitha
Ukulungisa i-laser ye-CW ukuze ukusebenza kahle kwenqubo kuhlanganisa ukugxila kumapharamitha athile asemqoka, kufaka phakathi amandla we-waveform, i-defalus, inani le-beam Spot, kanye nesivinini sokucubungula. Ukuhlelwa okuqondile kwalezi zinhlaka kubalulekile ekufezeni imiphumela engcono kakhulu yokucubungula, ukuqinisekisa ukusebenza kahle kanye nekhwalithi emishini yemishini ye-laser.
Umdwebo oqhubekayo we-laser namandla
Izici zokusatshalaliswa kwamandla
Isici esiphawuleka sama-CW Lasers ukusatshalaliswa kwamandla abo e-Gaussian amandla, lapho ukusatshalaliswa kwamandla kwesigaba se-laser beam's cross Lesi sici sokusabalalisa sivumela ama-CW Lasers ukufezekisa ukunemba okuphezulu kakhulu nokusebenza kahle, ikakhulukazi kuzinhlelo zokusebenza ezidinga ukuthunyelwa kwamandla okugxilwe.

Izinzuzo ze-Waser Wave (CW) laser welding
Umbono we-micruclitural
Ukuhlola i-MicrossCreat of Metals kuveza izinzuzo ezihlukile ze-wavel wave (CW) laser welding ngaphezulu kwe-quasi-aqhubekayo wave (QCW) i-pulse welding. I-QCW Pulse Welding, icindezelwe umkhawulo wemvamisa yayo, imvamisa cishe ngo-500hz, ibhekene nokuhweba phakathi kwezinga lokugqagqana nokuphishelwa ukungena. Izinga eliphansi le-Overlap liphumela ekujuleni okunganele, kanti isilinganiso esiphezulu se-Overlap sivimba isivinini se-welding, ukunciphisa ukusebenza kahle. Ngokuphambene, cw laser welding, ngokukhethwa kwamadayimitha afanele ama-laser aqine kanye namakhanda we-welding, afezekisa ukufudumala okusebenzayo nokuqhubekayo. Le ndlela ibonakala inokwethenjelwa kakhulu kwizicelo ezidinga ubuqotho bezinsuku eziphakeme.
Ukucatshangelwa kwe-Thermal Impact
Ngokombono womthelela we-thermal, i-QCW Pulse Laser Welding ihlushwa impikiswano yokudlula, okuholela ekushiseni okuphindaphindiwe komthungo we-weld. Lokhu kungakwazi ukwethula ukungahambelani phakathi kwe-microscucture yensimbi kanye nezinto zabazali, kufaka phakathi ukwehluka kosayizi wokungenisa kanye namanani okupholisa, ngaleyo ndlela kwamukele ubungozi bokuqhekeka. Ngakolunye uhlangothi i-CW laselding, ngakolunye uhlangothi, igwema lolu daba ngokunikeza inqubo efanayo yokushisa futhi eqhubekayo yokushisa.
Ukulungiswa kokulungiswa
Mayelana nokusebenza nokulungiswa, i-QCW laser welding ifuna ukuhlelwa okumangazayo kwamapharamitha amaningana, kufaka phakathi imvamisa yokuphindaphinda kwe-pulse, amandla aphezulu, ububanzi be-pulse, umjikelezo wokudla, nokuningi. I-CW Laser Welding yenza lula inqubo yokulungiswa, igxile kakhulu kwi-waveform, ijubane, amandla, kanye nenani le-defacus, ukunciphisa kakhulu ubunzima bokusebenza.
Inqubekela phambili yezobuchwepheshe kuCW laser welding
Ngenkathi i-QCW Laser Welding yaziwa ngamandla ayo aphezulu aphezulu kanye nokufakwa okushisayo okushisayo, inenzuzo ye-Welding Helden Companing Technology (ukuthuthuka okungenhla kwama-Waser welding (ukuthuthuka okungenhla kwama-Waser we-Wats) kanye ne-Reget Feneteration Welding ngokususelwa ekusebenzeni kohlelo lokusebenza nasekusebenzeni kwayo. Lolu hlobo lwe-laser lufaneleke kakhulu ngezinto zokwakha zikhulu kune-1mm, zifinyelela isilinganiso esiphakeme kakhulu (ngaphezulu kwe-8: 1) naphezu kokufakwa okuphezulu kokushisa okuphezulu.
I-Quasi-eqhubekayo
Ukusatshalaliswa Kwamandla Okugxile
I-QCW, ime nge- "quasi-igagasi eliqhubekayo," imele ubuchwepheshe be-laser lapho i-laser ikhipha ukukhanya ngendlela enciphile, njengoba kuboniswe kuMfanekiso a. Ngokungafani nokusatshalaliswa kwamandla okufanayo kwama-lome-mode aqhubekayo ama-lasers aqhubekayo, ama-QCW ama-lasers agxilisa amandla awo kakhulu. Lesi simo sezinkomba ze-QCW Lasers aqoqo amandla aphakeme, ukuhumusha kumakhono wokungena onamandla. Umphumela we-metallurgical ongumphumela ufana nokwakheka "kwezipikili" ngesilinganiso esijulile sokujula, okuvumela ama-QCW lasers ukugqamisa kuzinhlelo zokusebenza ezibandakanya ama-alloys aphezulu, izinto ezibucayi zokushisa, ukunemba kwe-micro-welding.
Ukuqina okuthuthukile nokuphazanyiswa kwePlume
Enye yezinzuzo ezaziwayo ze-QCW Laser Welding yikhono layo ukunciphisa imiphumela yeplanethi yensimbi endaweni yokutholwa kwezinto ezibonakalayo, okuholela kwinqubo ezinzile. Ngesikhathi sokusebenzisana kwe-laser-material, ukuhwamuka okukhulu kungadala ingxubevange yensimbi yensimbi kanye ne-plasma ngaphezulu kwechibi elincibilikayo, okuvame ukubizwa ngokuthi yi-plume yensimbi. Le Plume ingavikela indawo yokwenziwa isuka e-laser, ibangele ukulethwa kwamandla namandla angazinzile futhi inezinkinga ezinjenge-spatter, amaphuzu wokuqhuma, nemigodi. Kodwa-ke, ukuphuma kwama-QCW Lasers (isib. Ukuqhuma kwe-5ms okulandelwa yi-10ms Pudlot) ukuthi i-Laser Pulazise ngayinye ifinyelela endaweni ebonakalayo engathinteki ngokungafanele yi-Plume yensimbi, okuholela ekuhlolweni kwe-welding okuqinile.
Izinzilo ezinzile amachibi echibini
Amandla we-Dyt Pool, ikakhulukazi ngokuya ngamabutho asebenza ku-keyhole, abaluleke kakhulu ekunqumeni ikhwalithi ye-weld. Ama-lasers aqhubekayo, ngenxa yokuvezwa kwawo isikhathi eside kanye nezindawo ezinkulu ezithintekile ukushisa, zivame ukudala amachibi amakhulu ancibilikayo agcwaliswe ngensimbi ewuketshezi. Lokhu kungaholela ekulimaleni okuhambisana namachibi amakhulu ancibilikayo, njengokuwa kwe-keyhole. Ngokuphambene nalokho, amandla agxile kanye nesikhathi esifushane sokuxhumana we-QCW Laser Welding gxila echibini elizungeze i-keyhole, okuholele ekusakazweni kwamandla okufana okufana kanye nesigameko esiphansi se-porincial, ukuqhekeka, kanye nokuphamba.
Isimo esinciphile ngokushisa (i-haz)
Izinto eziqhubekayo ze-laser welding izifundo zokushisa ezishisayo, okuholela ekutholeni okuthe xaxa kokuqukethwe. Lokhu kungadala ukungathandeki kwezezimali okungekho emthethweni kanye nokuphazamiseka okubangelwa ukucindezelwa ezintweni ezincanyana. Ama-QCW lasers, ngokusebenza kwawo ngezikhathi ezithile, avumele isikhathi sezinto zokwakha ukuze apholile, ngaleyo ndlela anciphise indawo ethintekile ekushiseni kanye nokufakwa okushisayo. Lokhu kwenza i-QCW Laser Welding ilungele ikakhulukazi izinto ezincanyana nalezo eziseduze nezinto ezibucayi zokushisa.
Amandla aphezulu aphezulu
Naphezu kwamandla ajwayelekile afana nama-lasers aqhubekayo, ama-QCW ama-lasers afinyelela amandla aphezulu aphezulu kanye nezinqumo zamandla, okuholela ekungenisweni okujulile kanye namakhono aqine aqine. Le nzuzo ishiwo ikakhulukazi ekushisweni kwamashidi amancanyana ethusi nama-aluminium alloys. Ngokuphambene nalokho, ama-lasers aqhubekayo anamandla afanayo anamandla angahle ahluleke ukumaka endaweni yokwaziswa ngenxa yobuningi bamandla aphansi, okuholela ekubonisweni. Ama-lasers anamandla aphezulu, ngenkathi ekwazi ukuncibilikisa lokho okuqukethwe, angathola ukwanda okubukhali kwezinga lokufakwa ngemuva kokuncibilika, okubangela ukujula okungalawuleki kokuncipha nokushiswa, okungafanele kutholakale ukumaka noma ukushiswa, ukwehluleka ukufeza izidingo zenqubo.
