Insimbi ye-carbon
Ngenxa yokuthi i-carbon steel iqukethe ikhabhoni, ayikuvezi ukukhanya ngamandla futhi imunca kahle imishayo yokukhanya.I-Carbon steel ifanele ukusika i-laser kuzo zonke izinto zensimbi.Ngakho-ke, imishini yokusika i-carbon steel laser inesikhundla esingenakunyakaziswa ekucubunguleni i-carbon steel.
Ukusetshenziswa kwe-carbon steel kuya ngokuya kunwebeka.Okwesimanjeimishini yokusika laseringasika ubukhulu obukhulu bamapuleti ensimbi ekhabhoni bufike ku-20MM.Umsele wokusika insimbi ye-carbon kusetshenziswa indlela yokuncibilika kwe-oxidative kanye nokusika ungalawulwa ube ububanzi obanelisayo.Kuze kube ngu-0.1MM.
Insimbi engagqwali
Insimbi engagqwali yokusika i-laser isebenzisa amandla akhishwayo lapho i-laser beam ifakwe imisebe endaweni yensimbi ukuze incibilike futhi ihwamuke insimbi engagqwali.Embonini yokukhiqiza esebenzisa ishidi lensimbi engagqwali njengengxenye eyinhloko, i-laser cutting steel stainless steel iyindlela yokucubungula esheshayo nephumelelayo.Imingcele yenqubo ebalulekile ethinta ikhwalithi yokusika yensimbi engagqwali ijubane lokusika, amandla e-laser, nomfutho womoya.
Uma kuqhathaniswa nensimbi ephansi ye-carbon, ukusika insimbi engagqwali kudinga amandla aphezulu e-laser nomfutho we-oxygen.Nakuba ukusika insimbi engagqwali kufeza umphumela wokusika owanelisayo, kunzima ukuthola ama-seams angena-slag ngokuphelele.I-nitrogen ene-high pressure kanye ne-laser beam ijovwa nge-coaxially ukuze ikhiphe insimbi encibilikisiwe ukuze kungabikho oksijini okwakhiwa endaweni yokusika.Lena indlela enhle, kodwa ibiza kakhulu kunendlela evamile yokusika umoya-mpilo.Enye indlela yokushintsha i-nitrogen ehlanzekile ukusebenzisa umoya ocindezelwe wezitshalo ohlungiwe, oqukethe i-nitrogen engama-78%.
Lapho i-laser isika isibuko sensimbi engagqwali, ukuze kuvinjwe ibhodi ekushiseni okukhulu, ifilimu ye-laser iyadingeka!
I-aluminium ne-alloy
Nakuba umshini wokusika we-laser ungasetshenziswa kabanzi ekucubunguleni izinto ezihlukahlukene zensimbi nezingezona zensimbi.Kodwa-ke, ezinye izinto, njengethusi, i-aluminium, nama-alloys azo, zenza ukusika kwe-laser kube nzima ukucutshungulwa ngenxa yezimpawu zabo (ukubonakala okuphezulu).
Njengamanje, i-aluminium plate laser cutting, i-fiber lasers kanye ne-YAG lasers isetshenziswa kabanzi.Zombili lezi zisetshenziswa zisebenza kahle ekusikeni i-aluminium nezinye izinto, njengensimbi engagqwali ne-carbon steel, kodwa futhi azikwazi ukucutshungulwa ngokushuba.I-Aluminium.Ngokuvamile, ubukhulu obukhulu be-6000W bungasikwa bube ku-16mm, futhi u-4500W ungasikwa ube ngu-12mm, kodwa izindleko zokucubungula ziphezulu.Igesi elisizayo elisetshenziswayo ikakhulukazi lisetshenziselwa ukuphephula umkhiqizo oncibilikisiwe endaweni yokusika, futhi ngokuvamile ikhwalithi engcono yokusika ingatholakala.Kwamanye ama-alloys e-aluminium, ukunakwa kufanele kukhokhwe ukuvimbela imifantu emincane ebusweni be-slit.
Ithusi nama-alloys
Ithusi elihlanzekile (ithusi) alikwazi ukusikwa nge-CO2 laser beam ngenxa yokubonakala kwayo okuphezulu kakhulu.Ithusi (ingxubevange yethusi) isebenzisa amandla e-laser aphezulu, futhi igesi elisizayo isebenzisa umoya noma umoya-mpilo, ongasika amapuleti amancane.
I-Titanium nama-alloys
Ukusika i-laser ye-titanium alloys evame ukusetshenziswa embonini yezindiza kunekhwalithi enhle.Nakuba kuzoba khona insalela encane enamathelayo ezansi kwesikwele, kulula ukuyisusa.I-titanium ehlanzekile ingahlanganiswa kahle namandla ashisayo aguqulwa yi-laser beam egxilile.Lapho igesi elisizayo lisebenzisa umoya-mpilo, ukusabela kwamakhemikhali kunolaka futhi isivinini sokusika siyashesha.Kodwa-ke, kulula ukwenza ungqimba lwe-oxide onqenqemeni lokusika, futhi ukushiswa ngokweqile ngengozi nakho kungenzeka.Ukuze kube nokuzinza, kungcono ukusebenzisa umoya njengegesi elisizayo ukuze uqinisekise ikhwalithi yokusika.
Insimbi ye-alloy
Izinsimbi eziningi ze-alloy structural kanye nezinsimbi ze-alloy zingasikwa nge-laser ukuthola ikhwalithi enhle yokusika.Ngisho nangezinye izinto eziphakeme kakhulu, inqobo nje uma imingcele yenqubo ilawulwa kahle, imiphetho yokusika eqondile ne-slag-free ingatholakala.Kodwa-ke, ezinsimbi zamathuluzi esivinini esikhulu eziqukethe i-tungsten nezinsimbi zokubunjwa okushisayo, ukukhumuzeka kanye ne-slagging kwenzeka ngesikhathi sokusika nge-laser.
Ingxube ye-nickel
Kunezinhlobo eziningi zama-alloys asekelwe ku-nickel.Iningi labo lingaba ngaphansi kokusikwa kwe-oxidative fusion.
Okulandelayo yividiyo yomshini wokusika we-fiber laser:
