I laser Welding umshini angathuthukisa hhayi kuphela emsebenzini ukuqeqesheka, kodwa futhi ukubonakala workpiece okuphelele omnandi, ukutshiyoza kwezinyoni weld lincane, ukujula Welding likhulu, kanti izinga Welding kuphezulu. Indlela ukuqinisekisa ikhwalithi Welding we-laser Welding umshini, eqinisweni, izici eziningi ezithinta izinga laser Welding, ake sithole.
1. zamandla ishayela laser
Amandla of ishayela laser: libhekisela amandla esiphezulu nomkhiqizo laser ishayela olulodwa, Phiko J (Joule). Lena ipharamitha esemqoka ye-laser, ebheka amandla esiphezulu ukuthi laser angakhiqiza. Ngokusho ukusetshenziswa ukukhanda isikhunta, amandla laser kungaba ukuhlangabezana nezidingo noma ngabe isiphi isikhathi ngezansi 70J, futhi amandla enkulu luyize, noma ngokuyinhloko Ayisetshenziswa, kanye nokwenyuka kwenani umthamo laser ugesi kanye ivolumu ka echibini ukushisa kunciphisa nekusebenta kwamandla.
2. Laser ugongolo indawo ubukhulu
Laser indawo focus ubukhulu: Lena ipharamitha kubaluleke kakhulu ibonisa ukuthi ukusebenza umklamo we-laser, amayunithi (mm), ebheka kwabantu amandla kucutshungulwa uhla laser. Uma umklamo optical we-laser uyacabangela futhi eziphambili, amandla laser bagxila, kugxilwa olunembile, kanye laser indawo ubukhulu zingalawulwa ku ezahlukene 0.2mm-2mm. Kungakhathaliseki focus ububanzi we-laser zingalawulwa at 0.2mm kuyigama esiqinile ngoba generator laser. ukuhlolwa. Lasers ngokuvamile yakhelwe eChina, ngoba nje ufuna ukwehlisa izindleko, ngakho-ke, ukucutshungulwa laser zedivayisi ilula, umklamo akuyona okunzima, le laser kuyinto etshiyeneyo kule komgodi, okuholela nobunzima olunembile ngokugxila, kanye laser indawo ububanzi we okukhipha laser akukhona ejwayelekile. Kuthiwa ukuba 0.2mm, kodwa kungenziwa kuphela ukufinyelela ubuncane 0.5mm. Ngenxa kwehlukana we-laser, ugongolo okukhipha laser ayikwazi ukuba simise njalo isiyingi, elibangela lesi langempela ngemisebe endaweni the laser to be too large and ablation of the weld seam. That is, unnecessary laser irradiation occurs at both ends of the weld to cause the two ends of the weld to be concave. This phenomenon is particularly serious for repairing the already polished mold, and sometimes even scraps the mold. The company's lasers are well-designed, with strict material selection and careful debugging, so that the beam spot diameter of the laser output can be precisely monitored, so that the size of the focused spot can be as small as 0.2mm and can be in the range of 0.2mm and 2mm. Carry out stepless adjustment to reach the international advanced level.
3. Imvamisa ishayela laser
Imvamisa ishayela laser: Lona lokubonisa bangaki pulses le laser ungenza ngomzuzu owodwa, amayunithi (Hz). Okokuqala, kufanele kuphawulwe ukuthi metal Welding iyona energy of nokusebenzisa i-laser, futhi esimweni njalo amandla laser, ayanda nobuningi, ezincane amandla ngayinye laser okukhiphayo. Ngakho-ke, kudingeka uqinisekise ukuthi amandla laser yanele ukuba Ncibilikisa metal thina. Endabeni isivinini processing, imvamisa ekhishwa laser kungaba azimisele. Endabeni amathuluzi laser-kwalungisa ukugaya, 15 Hz kungaba ukuhlangabezana nezidingo Welding. Ngokweqile imvamisa high nakanjani abangele amandla ishayela we-laser ukuba iphansi kakhulu, okuholela Welding ukwehluleka.
4. umumo gagasi ishayela we-laser kanye isihlobo ukukhanya ukumuncwa ngesilinganiso kwento okufanele ashiselwe
Pulse umumo gagasi laser: Ukuze pulsed laser ukucutshungulwa, laser ishayela umumo gagasi inkinga ebalulekile pulsed laser Welding. Lapho laser ephezulu umfutho kuyinto ngesenzakalo yendwangu, ebusweni metal ibonisa 60% kuya ku-98% wamandla laser, kanye reflectance siyahlukahluka izinga lokushisa kwamanzi. Ngakho-ke, i-reflectivity we-laser kanye ukusetshenziswa izinga laser ahlukile ngezinto ezihlukahlukene. Ukuze enze Welding ngempumelelo, kubalulekile ukuba lasers uvo waveforms ezahlukene, ukuze isakhiwo metal ngesikhathi weld kungenziwa acacisa ngendlela elilungile ukwakha matrix. Sakhiwo metal uhambisane ungakheka eliphezulu weld. I jikelele imishini yasekhaya zisebenzisa ezishibhile olulodwa-wave amandla laser. Ngakho-ke, i-Welding lingaphansi nezimo, kunzima ukuzivumelanisa Welding isikhunta izinto ezihlukahlukene, futhi ngokuvamile sibuyekeze wenziwa, okuyinto akachithi kakhulu nesikhathi izinto Welding futhi kungabangela isikhunta. kulahlwe. metal izinto ezehlukene zinezidingo ngamazinga ahlukene ukucabangisisa ukumuncwa laser ukukhanya, kanye laser efanayo uyoveza ezahlukene Welding nemiphumela ngezinto ezihlukahlukene, futhi kuthinte Ukungena yayo, Welding isivinini, isivinini crystallization kanye ubulukhuni, ngakho igagasi elilodwa unxande zokushisela kungaxazululi nezidingo ezahlukene Welding isikhunta metal.
