Gusudira hakoreshejwe laser ni iki? Gusobanura Gusudira hakoreshejwe laser! Ibyo ukeneye kumenya byose ku bijyanye no gusudira hakoreshejwe laser, harimo n'amahame y'ingenzi n'ibipimo by'ingenzi by'imikorere!
Abakiriya benshi ntibasobanukiwe amahame shingiro y'imikorere y'imashini isudira hakoreshejwe laser, ndetse no guhitamo imashini isudira hakoreshejwe laser ikwiye, icyakora Mimowork Laser irahari kugira ngo igufashe gufata icyemezo gikwiye no gutanga ubufasha bw'inyongera kugira ngo igufashe gusobanukirwa isudira hakoreshejwe laser.
Gusudira hakoreshejwe laser ni iki?
Gusudira hakoreshejwe laser ni ubwoko bwo gusuka, hakoreshejwe laser nk'isoko y'ubushyuhe, ihame ryo gusudira ni uko uburyo bwihariye bwo gukangura imikorere y'icyuma, bigatuma habaho guhindagurika kw'ibice bihumeka, hanyuma bigahinduka imirasire ishyushye, iyo imirasire n'igice cy'umurimo bihuye, ingufu zinjira mu gice cy'umurimo, iyo ubushyuhe bugeze aho ibintu bishongesha bushobora gusudira.
Dukurikije uburyo bw'ingenzi bwo gusudira pisine, gusudira hakoreshejwe laser ifite uburyo bubiri bw'ibanze bwo gusudira: gusudira ubushyuhe no gusudira mu buryo bwimbitse (imfunguzo). Ubushyuhe buturuka ku gusudira hakoreshejwe extension bukwirakwira mu gice cy'akazi binyuze mu kwimura ubushyuhe, kugira ngo ubuso bwo gusudira bushonge, nta mwuka ukwiye kubaho, ukunze gukoreshwa mu gusudira ibice byoroheje byihuta. Gusuka mu buryo bwimbitse bihindura umwuka w'ibikoresho kandi bigatera plasma nyinshi. Bitewe n'ubushyuhe bwinshi, hazaba hari imyobo imbere ya pisine ishongeshejwe. Gusuka mu buryo bwimbitse ni bwo buryo bwo gusudira hakoreshejwe laser bukoreshwa cyane, bushobora gusudira neza igice cy'akazi, kandi ingufu zinjiye ni nyinshi, bigatuma umuvuduko wo gusudira wihuta.
Ibipimo by'imikorere mu gusudira hakoreshejwe laser
Hari ibipimo byinshi bigira ingaruka ku bwiza bwa laser welding, nko kuba ingufu nyinshi, uburyo laser pulse waveform, defocusing, umuvuduko wo gusudira ndetse no guhitamo gaze y’ubufasha yo kurinda.
Ubucucike bw'ingufu za laser
Ubucucike bw'ingufu ni kimwe mu bipimo by'ingenzi mu gutunganya lazeri. Iyo ubucucike bw'ingufu bwinshi bushobora gushyuha kugeza ku bushyuhe mu masegonda make, bigatuma habaho ubushyuhe bwinshi. Kubwibyo, ubucucike bw'ingufu nyinshi ni ingirakamaro mu bikorwa byo gukuraho ibikoresho nko gucukura, gukata no gushushanya. Ku bucucike bw'ingufu nke, bifata milisegonda nyinshi kugira ngo ubushyuhe bw'ubuso bugere ku bushyuhe, kandi mbere yuko ubuso buhinduka ubushyuhe, hasi bugera ku bushyuhe, byoroshye gukora ubushyuhe bwiza bwo gushonga. Kubwibyo, mu buryo bwo gusudira lazeri ikoresha ubushyuhe, ubucucike bw'ingufu ni 104-106W/cm2.
Umuraba w'ingufu za Laser
Imiterere y'umuvuduko wa laser si ikintu cy'ingenzi gusa mu gutandukanya gukuraho ibikoresho no gushonga kw'ibikoresho, ahubwo ni n'ikintu cy'ingenzi mu kumenya ingano n'igiciro cy'ibikoresho byo gutunganya ibikoresho. Iyo umurimbo wa laser ufite imbaraga nyinshi urashwe ku buso bw'ibikoresho, ubuso bw'ibikoresho buzaba bufite 60 ~ 90% by'ingufu za laser zigaragara kandi zifatwa nk'izitakaye, cyane cyane zahabu, ifeza, umuringa, aluminiyumu, titaniyumu n'ibindi bikoresho bifite reflection ikomeye kandi byihuta mu gutwara ubushyuhe. Reflection y'icyuma irahinduka uko igihe kigenda mu gihe cy'impeshyi ya laser. Iyo ubushyuhe bw'ubuso bw'ibikoresho buzamutse bukagera aho bushonga, reflection igabanuka vuba, kandi iyo ubuso buri mu gihe cyo gushonga, reflection irahagarara ku giciro runaka.
Ubugari bwa Laser Pulse
Ubugari bw'imitsi ni ikintu cy'ingenzi mu gusudira hakoreshejwe laser. Ubugari bw'imitsi bwagenwaga n'ubujyakuzimu bw'aho ubushyuhe bwinjiriye n'aho ubushyuhe bwinjiriye. Uko ubugari bw'imitsi bwari burebure, ni ko n'aho ubushyuhe bwinjiriye habaga hanini, kandi ubujyakuzimu bw'aho ubushyuhe bwinjiriye bwiyongera hamwe na 1/2 cy'ubugari bw'imitsi. Ariko, kwiyongera k'ubugari bw'imitsi bizagabanya imbaraga z'umuvuduko, bityo kwiyongera k'ubugari bw'imitsi muri rusange bikoreshwa mu gusudira ubushyuhe, bigatuma ingano ya bunini kandi ndende ikoreshwa mu gusudira, cyane cyane ikwiriye gusudira amasahani yoroheje kandi manini. Ariko, imbaraga nke z'umuvuduko zituma ubushyuhe burushaho kwiyongera, kandi buri gikoresho gifite ubugari bwiza bw'imitsi butuma uburebure bw'aho ubushyuhe bwinjirira burushaho kwiyongera.
Umubare wo gukuraho icyitegererezo
Ubusanzwe gusudira hakoreshejwe laser bisaba gukuraho imiterere runaka, kuko ubucucike bw'ingufu z'ahantu hagati kuri laser focus buba buri hejuru cyane, ibyo bikaba byoroshye gutuma ibikoresho byo gusudira bihinduka imyobo. Ubucucike bw'ingufu bukwirakwira buri mu rugero rumwe muri buri gice kure y'aho laser focus iherereye.
Hari uburyo bubiri bwo gukuraho focus:
Gutandukanya neza n'ibitari byiza. Iyo urwego rw'ibanze ruri hejuru y'aho ikigo gikorera, ruhinduka ubwiza; bitabaye ibyo, ruhinduka ubwiza. Dukurikije inyigisho ya geometric optic, iyo intera iri hagati y'urwego rw'imbere n'urundi rudahuza neza n'urwego rw'ingufu zo gusudira zingana, ubucucike bw'imbaraga ku rwego rujyanye narwo buba bungana, ariko mu by'ukuri, imiterere y'ikigega cyashongeshejwe iratandukanye. Mu gihe cyo gutandukanya nabi, hashobora kuboneka uburyo bwinshi bwo kwinjira, bujyanye n'uburyo ikigega cyashongeshejwe cyashongeshejwe cyashongeshejwe.
Umuvuduko wo gusudira
Umuvuduko wo gusudira ugena ubwiza bw'ubuso bwo gusudira, uburebure bw'ubujyakuzimu, agace kagizweho ingaruka n'ubushyuhe n'ibindi. Umuvuduko wo gusudira uzagira ingaruka ku bushyuhe bukoreshwa kuri buri gice. Iyo umuvuduko wo gusudira ugabanutse cyane, ubushyuhe bukoreshwa cyane, bigatuma igikoresho cyo gusudira gishya. Iyo umuvuduko wo gusudira wihuta cyane, ubushyuhe bukoreshwa gato cyane, bigatuma igice cyo gusudira gitangira gukora igice kandi kitarangiye. Kugabanya umuvuduko wo gusudira bikunze gukoreshwa kugira ngo binoze uburyo bwo kwinjira.
Gazi yo kurinda ibihuha by'inyongera
Gazi yo gufasha mu kurinda umuyaga ni igikorwa cy'ingenzi mu gusudira hakoreshejwe lazeri ifite imbaraga nyinshi. Ku ruhande rumwe, ni ukugira ngo wirinde ko ibikoresho by'icyuma bisuka mu kirere no kwanduza indorerwamo ireba kure; ku rundi ruhande, ni ukugira ngo plasma ikorwa mu gusudira ikomeze kwibanda cyane no kubuza lazeri kugera ku buso bw'ibikoresho. Mu gusudira hakoreshejwe lazeri, helium, argon, azote n'indi myuka ikunze gukoreshwa mu kurinda ikidendezi cyashongeshejwe, kugira ngo hirindwe ko igikoresho cyashongeshejwe cyangirika mu buhanga bwo gusudira. Ibintu nk'ubwoko bwa gaze irinda, ingano y'umwuka utemba n'inguni itera umuyaga bigira ingaruka zikomeye ku musaruro wo gusudira, kandi uburyo butandukanye bwo gusudira nabwo buzagira ingaruka ku bwiza bwo gusudira.
Igikoresho cyacu cyo gusudira hakoreshejwe laser gikozwe mu ntoki cyatugiriye inama:
Umusudizi wa Laser - Ahantu ho gukorera
◾ Ubushyuhe bw'aho bakorera: 15~35 ℃
◾ Ingano y'ubushuhe aho bakorera: < 70% Nta bushyuhe bukabije
◾ Gukonjesha: icyuma gikonjesha amazi ni ngombwa bitewe n'imikorere yo gukuraho ubushyuhe ku bice bikuraho ubushyuhe bya laser, bigatuma icyuma gisudira laser gikora neza.
(Ikoreshwa rirambuye n'ubuyobozi ku bijyanye n'icyuma gikonjesha amazi, ushobora kureba ibi bikurikira:Ingamba zo kwirinda gukonjesha kuri sisitemu ya laser ya CO2)
