Ubuchwepheshe bokujoyina i-laser, noma ubuchwepheshe bokushisela i-laser, busebenzisa umsebe we-laser onamandla amakhulu ukugxila nokulawula ukukhanyiswa kobuso bezinto ezibonakalayo, kanti ubuso bezinto ezibonakalayo bumunca amandla e-laser bese buwaguqula abe amandla okushisa, okwenza izinto zifudumale futhi zincibilike endaweni, kulandelwe ukupholisa nokuqina ukuze kufezwe ukuhlanganiswa kwezinto ezifanayo noma ezingafani. Inqubo yokushisela i-laser idinga ubuningi bamandla e-laser obuyi-104kuya ku-108I-W/cm2Uma kuqhathaniswa nezindlela zokushisela zendabuko, ukushisela nge-laser kunezinzuzo ezilandelayo.

Ifu le-plasma eli-1, izinto ezincibilikisayo ezi-2, imbobo yokhiye emi-3, ukujula oku-4 kokuhlanganiswa
Ngenxa yokuba khona kwembobo yokhiye, umsebe we-laser, ngemva kokukhanyisa ingaphakathi lembobo yokhiye, uzokwandisa ukumuncwa kwe-laser yizinto futhi ukhuthaze ukwakheka kwechibi elincibilikisiwe ngemva kokuhlakazeka neminye imiphumela, izindlela ezimbili zokushisela ziqhathaniswa kanje.
Isithombe esingenhla sinikeza inqubo yokushisela nge-laser yezinto ezifanayo kanye nomthombo wokukhanya ofanayo, indlela yokuguqula amandla yenziwa kuphela nge-keyhole, i-keyhole kanye nensimbi encibilikisiwe eduze kodonga lomgodi kuhamba ngokuqhubekela phambili komsebe we-laser, insimbi encibilikisiwe isusa i-keyhole emoyeni oshiywe ngemuva ukuze igcwale futhi ngemva kokujiya, yakha umthungo wokushisela.
Uma izinto ezizoshintshwa ziyinsimbi engafani, ukuba khona komehluko ezimpahleni zokushisa kuzoba nomthelela omkhulu enqubweni yokushintshwa, njengomehluko ezindaweni zokuncibilika, ukuhanjiswa kokushisa, umthamo wokushisa othize, kanye nama-coefficients okunwebeka kwezinto ezahlukene, okuholela ekucindezelekeni kokushintshwa, ukuguqulwa kokushintshwa, kanye nezinguquko ezimweni zokukristala kwensimbi ehlanganisiwe eshitshiwe, okubangela ukwehla kwezakhiwo zemishini zokushintshwa.
Ngakho-ke, ngokwezici ezahlukene zendawo yokushisela, inqubo yokushisela ithuthukise ukushisela kokugcwalisa i-laser, ukushisela nge-laser, ukushisela nge-laser enemisebe emibili, ukushisela nge-laser composite, njll.
Ukushisela Ukugcwalisa Intambo Ye-Laser
Enqubweni yokushisela nge-laser ye-aluminium, i-titanium kanye ne-copper alloys, ngenxa yokumuncwa okuncane kokukhanya kwe-laser (<10%) kulezi zinto, i-plasma ekhiqizwe ngesithombe inokuvikela okuthile kokukhanya kwe-laser, ngakho-ke kulula ukwakha i-spatter futhi kuholele ekwakhiweni kwamaphutha anjenge-porosity kanye nemifantu. Ngaphezu kwalokho, ikhwalithi yokushisela nayo iyathinteka lapho igebe phakathi kwezinto zokusebenza likhulu kunobubanzi be-spot ngesikhathi sokushisela kwepuleti elincane.
Ekuxazululeni izinkinga ezingenhla, umphumela ongcono wokushisela ungatholakala ngokusebenzisa indlela yezinto zokugcwalisa. Isigcwalisi singaba ucingo noma ufulawa, noma indlela yokugcwalisa esethiwe ingasetshenziswa. Ngenxa yendawo encane egxile kuyo, isigcwalisi siba sincane futhi sibe nesimo esijiyile kancane ebusweni ngemva kokusetshenziswa kwezinto zokugcwalisa.
Ukushiswa Kwe-Laser
Ngokungafani nokushisela okuhlanganisiwe, okuncibilikisa izingxenye ezimbili ezihlanganisiwe ngesikhathi esisodwa, ukushisela kwengeza into yokugcwalisa enephuzu lokuncibilika eliphansi kunezinto eziyisisekelo ebusweni bokushisela, kuncibilikisa into yokugcwalisa ukuze kugcwaliswe isikhala ekushiseni okuphansi kunephuzu lokuncibilika kwezinto eziyisisekelo kanye nephuzu lokuncibilika kwezinto ezigcwalisayo, bese kuhlangana ukuze kwakheke i-weld eqinile.
I-Brazing ifaneleka kumadivayisi e-microelectronic azwela ukushisa, amapuleti amancane, nezinto zensimbi ezishintshashintshayo.
Ngaphezu kwalokho, ingahlukaniswa kabanzi ngokuthi i-soft brazing (<450 °C) kanye ne-hard brazing (>450 °C) kuye ngokuthi izinga lokushisa lifudunyezwa kuphi.
Ukushisela Kwe-Laser Ye-Dual Beam
Ukushisela ngemisebe emibili kuvumela ukulawulwa okuguquguqukayo nokulula kwesikhathi nendawo yokushiswa ngemisebe ye-laser, ngaleyo ndlela kulungisa ukusatshalaliswa kwamandla.
Isetshenziswa kakhulu ekushiseni nge-laser kwama-aluminium nama-magnesium alloys, ukushiseni i-splice nama-lap plate ezimotweni, ukushiseni nge-laser kanye nokushiseni okujulile.
Ugongolo oluphindwe kabili lungatholakala ngama-laser amabili azimele noma ngokuhlukaniswa kogongolo nge-splitter yogongolo.
Lezi zinsimbi ezimbili zingaba inhlanganisela yama-laser anezici zesizinda sesikhathi ezahlukene (i-pulsed vs. continuous), ama-wavelength ahlukene (ama-wavelength aphakathi kwe-infrared vs. ebonakalayo) kanye namandla ahlukene, angakhethwa ngokuya ngezinto ezicutshunguliwe zangempela.
4. Ukushisela Okuhlanganisiwe Kwe-Laser
Ngenxa yokusebenzisa umsebe we-laser njengomthombo wokushisa kuphela, ukushiswa kwe-laser yomthombo wokushisa owodwa kunesilinganiso sokuguqulwa kwamandla aphansi kanye nesilinganiso sokusetshenziswa, isikhombimsebenzisi se-port yezinto eziyisisekelo sokushiswa kulula ukukhiqiza ukungalungi kahle, kulula ukukhiqiza ama-pores kanye nemifantu kanye nokunye ukushiyeka, ukuze uxazulule le nkinga, ungasebenzisa izici zokushisa zeminye imithombo yokushisa ukuze uthuthukise ukushiswa kwe-laser endaweni yokusebenza, evame ukubizwa ngokuthi ukushiswa kwe-laser composite.
Uhlobo oluyinhloko lokushisela okuhlanganisiwe kwe-laser ukushisela okuhlanganisiwe kwe-laser kanye ne-arc kagesi, umphumela ongu-1 + 1 > 2 umi kanje.
ngemuva kokukhanya kwe-laser eduze kwe-arc esetshenzisiwe,ubuningi bama-electron buncishisiwe kakhulu, ifu le-plasma elikhiqizwa ukushiswa kwe-laser liyancishiswa, okuyintokungenza izinga lokumuncwa kwe-laser lithuthuke kakhulu, kuyilapho i-arc esezansi yokushisa kusengaphambili kuzokwandisa izinga lokumuncwa kwe-laser.
2. ukusetshenziswa kwamandla aphezulu kwe-arc kanye nesambaukusetshenziswa kwamandla kuzokwanda.
3, indawo yokusebenza yokushisela nge-laser incane, kulula ukuyibangela ukungalungi kahle kwembobo yokushisela, kuyilapho isenzo sokushisa se-arc sikhulu, esingakwaziukunciphisa ukungalingani kwembobo yokushiselaNgesikhathi esifanayo,ikhwalithi yokushisela kanye nokusebenza kahle kwe-arc kuyathuthukangenxa yomphumela wokugxila nokuqondisa womsebe we-laser ku-arc.
4, ukushisela nge-laser okunokushisa okuphezulu, indawo enkulu ethintekile ekushiseni, ukupholisa okusheshayo kanye nesivinini sokuqina, kulula ukukhiqiza imifantu kanye nama-pores; kuyilapho indawo ye-arc ethintekile ekushiseni incane, okunganciphisa i-gradient yokushisa, ukupholisa, isivinini sokuqina,kunganciphisa futhi kuqede ukukhiqizwa kwama-pores kanye nemifantu.
Kunezinhlobo ezimbili ezivamile zokushisela okuhlanganisiwe kwe-laser-arc: ukushisela okuhlanganisiwe kwe-laser-TIG (njengoba kuboniswe ngezansi) kanye nokushisela okuhlanganisiwe kwe-laser-MIG.
Kukhona nezinye izinhlobo zokushisela ezifana ne-laser kanye ne-plasma arc, i-laser kanye ne-inductive heat source compound welding.
Mayelana ne-MavenLaser
I-Maven Laser ingumholi wohlelo lokusebenza lwezimboni ze-laser eShayina futhi ingumhlinzeki onegunya wezixazululo zokucubungula i-laser zomhlaba wonke. Siyaqonda ngokujulile ukuthambekela kwentuthuko embonini yokukhiqiza, sihlala sicebisa imikhiqizo nezixazululo zethu, sigcizelela ukuhlola ukuhlanganiswa kokuzenzakalela, ulwazi kanye nobuhlakani nemboni yokukhiqiza, sihlinzeka ngemishini yokushisela i-laser, imishini yokumaka i-laser, imishini yokuhlanza i-laser kanye nemishini yokusika ubucwebe begolide nesiliva ye-laser yezimboni ezahlukahlukene kufaka phakathi uchungechunge lwamandla aphelele, futhi siqhubeka nokwandisa ithonya lethu emkhakheni wemishini ye-laser.
