Kubudirira kwesimbi nelaser weldinginotsamira pahwaro hwayo hwemuviri. Semuenzaniso, kutarisisa kwakanyanya kunogona kukanganisa simba relaser, nepo yakakwira yekupisa conductivity ichibvisa kupisa nekukurumidza kubva munzvimbo yeweld. Hunhu uhwu, pamwe chete nekunyungudika, zvinotarisa kuti chinhu chinotora simba zvakadii kuti chiumbe weld yakasimba, chaiyo.
Heino kuparara kwesimbi dzakajairwa uye kuti zvinhu zvadzo zvinopinda sei.
Laser Welding Carbon Steel
Carbon simbi isimbi-kabhoni alloy inosvika 2.1% kabhoni yemukati. Iyo kabhoni yemukati ndiyo yekutanga mhedzisiro yezvinhu zvayo.
Yakaderera-kabhoni simbi(isingasviki 0.25% kabhoni) ine ductile, yakaoma, uye inogoneka nyore uye inokwenenzverwa. Inowanzo shandiswa kune mapaneru emuviri, waya, uye mapaipi.
Simbi yepakati-kabhoni(0.25% kusvika 0.60% carbon) yakasimba uye yakaoma kudarika pasi-carbon steel. Izvi zvinoita kuti ive yakakodzera kune zvinhu zvinoda simba rakawanda uye kupfeka kuramba, senge magiya, shafts, uye mavhiri enjanji.
High-carbon steel(inodarika 0.60% kabhoni) ndiyo yakasimba uye yakaomesesa pavatatu, asi zvakare idiki ductile uye yakanyanya brittle. Kuomarara kwayo kunoita kuti ive yakanaka pakucheka maturusi, zvitubu, uye waya dzakasimba, asi inoda kunyatsobatwa panguva yewelding kudzivirira kutsemuka.
Carbon simbi ibhiza rekushanda mukugadzira, uye zvinotora kuti laser welding inonaka.
Zvakanakira: Iwe unowana yakasimba, yakadzika welds nekunyatso kunoshamisa uye kushoma kutsveyamisa. Iyo yekumhanyisa yakakura kuwedzera, inosimudzira chibereko pafekitori pasi.
Pfungwa: Iko kukurumidza kutonhora kweiyo laser process kunogona kuita weld brittle uye kungoita kuputika. Dzimwe nguva, preheating chikamu chakakosha kunonoka kutonhora uye kudzivirira nyaya.
Laser Welding Stainless Simbi
Uyu ndiwo mutambo wakaitwa kudenga. Laser welding ndiyo nzira yakakwana yesimbi isina tsvina, kunyanya kumaindasitiri anoda kuchena.
Zvakanakira: Iyo yakaderera, yakanangana nekupisa yekuisa kuhwina kukuru. Inochengetedza zvimisikidzo zvisingadziviriri zvesimbi isina tsvina nekudzivirira chimwe chinhu chinonzi "carbide precipitation." Izvi zvinoguma nekuvhiya kwakachena uye kwakanyatso simbi, ndosaka ichizivikanwa zvakanyanya mumaindasitiri ezvekurapa uye ezvekudya.
Pfungwa: Masimbi akawanda akajairika, senge mazana matatu akatevedzana (semuenzaniso, 304, 316), anokwenenzverwa zvakanyanya. Nekudaro, mamwe magiredhi, senge mazana mana akateedzana, anogona kuita brittle munzvimbo ine kupisa-yakakanganiswa.
Laser Welding Aluminium
Welding aluminium yagara ichinetsa, asi laser welding iri kuchinja mutambo.
Zvakanakira: Aluminium yakakura kupisa conductor, izvo zvinoreva neyakajairwa welding, kupisa kunopararira kunze uye kunoita kuti chikamu chose chiwedzere. Iyo laser yakatarisana nesimba uye yakaderera kupisa yekuisa inogadzirisa dambudziko iri, zvakanyanya kuderedza kukanganisa.
Pfungwa: Aluminium inoratidzira zvakanyanya. Iyo inopenya yepamusoro inogona kubvongodza laser beam ipapo. Kubudirira kunoenderana nezvinhu zvishoma zvakakosha: kuchenesa nzvimbo isina gwapa, gasi rekudzivirira rakakodzera, uye kushandisa iyo chaiyo mhando yelaser (fiber lasers inowanzofarirwa) kuve nechokwadi chekuti simba rinonyura.
Laser Welding Titanium
Kana iwe uchida weld titanium, laser ndeimwe yeako akanakisa maturusi ebasa racho.
Zvakanakira: Titanium isimbi inobatika, zvichireva kuti inosvibiswa nyore neokisijeni mumhepo kana yanyungudutswa, zvinotungamira kune isina simba, brittle weld. Iko kumhanya kwelaser uye kurongeka kunoderedza nguva iyo simbi inonyungudutswa nekufumurwa, ichideredza njodzi yekusvibiswa uye kunyungudutswa.
Pfungwa: Sezvakangoita neTIG welding titanium, iwe uchiri kufanira kungwarira zvakanyanya. Kuchena kwakakwana uye kudzivirira kwakakwana negesi inert (senge argon) haigone kutaurirana.
Laser Welding Mhangura uye Dzimwe Reflective Metals
Apa ndipo apo laser welding inosundira miganhu yezvinogoneka.
Zvakanakira: Laser welding muchina unogona kujoinha zvinhu zvinoratidzira zvakanyanya semhangura, izvo zvakaoma zvikuru kuomesa nechero imwe nzira. Izvi zvakakosha kune zvikumbiro senge mota yemagetsi (EV) mabhatiri, uko mhangura nealuminium zvinofanirwa kubatanidzwa.
Pfungwa: Izvi inyanzvi-chikamu zvinhu. Iyo yakanyanya kutaridzika uye yekupisa conductivity inogona kukuvadza iyo laser optics kana isina kubatwa nemazvo. Zvinowanzoda midziyo yakakosha, pamwe chete nehunyanzvi hwepamusoro.
Chii chinonzi Lkutevedzera Laser Welding?
Kunyange zvichinzwika sechishamiso chishandiso, hachina kukwana kumabasa ese. Zvakakosha kuti unzwisise kusawirirana.
1.High Initial Cost: Inyanzvi laser welding muchina yakakosha mari, inodhura zvakanyanya kupfuura yechinyakare MIG kana TIG setups.
2.Strict Joint Zvinodiwa: Sezvambotaurwa, lasers inoda pedyo-yakakwana kukwana. Kana zvikamu zvako zviine mapundu kana zvisina kuchekwa chaizvo, laser haizokwanisi kuvharisa zvakanaka.
3.Reflectivity Issues: Zvishandiso zvinopenya senge aluminium nemhangura zvinogona kuoma kupinza pasina hunyanzvi lasers uye matekiniki.
4.Zvekuchengetedza: Iyo yakakwira-intensity laser beam ine njodzi zvakanyanya uye inogona kukonzera zvakanyanya kukuvara kweziso uye kutsva kweganda, kunyangwe kubva pakuratidzira. Zvakakodzera kuchengetedza zvakavharirwa uye zvekuzvidzivirira nazvo zvemunhu (PPE) zvinosungirwa chose.
Maitiro Akanakisisa eKusina Mhosva Laser Welds
Kuti uwane zvakanyanya kubva pane yako laser welding process, unofanirwa kuroverera izvo zvakakosha.
Kugadzirira ndizvo Zvose
Joint Fit-Up: Hatigone kuzvitaura zvakakwana: zvikamu zvako zvinofanirwa kubatana zvakasimba. Rongedza gap isingasviki 10% yehukobvu hwezvinhu kuti uwane mhedzisiro yakanaka.
Surface Cleaning: Bvisa zvese zvisiri simbi. Izvi zvinoreva kubvisa mafuta ese, girizi, maokisi, uye chero zvimwe zvinosvibisa. Nzvimbo yakachena yakakosha kudzivirira pores uye kumwe kukanganisa mune yako weld.
Dzora Maitiro Ako
Shielding Gasi: Kungofanana neTIG neMIG, laser welding inoshandisa inert gasi (kazhinji argon kana helium) kuchengetedza dziva rakanyungudutswa kubva kuokisijeni uye nitrogen mumhepo, kuve nechokwadi chesimba rakasimba, rakachena.
Parameter Optimization: Iwe unofanirwa kufona mune yako marongero. Simba reLaser, kumhanya kwewelding, uye chinhambwe chekutarisa chinofanirwa kuve chakanyatso kurongeka kune chaiyo zvinhu uye ukobvu iwe wauri kushanda nawo.
Chengetedzo Kutanga, Nguva Dzose
Laser welding haisi nzira yaungave wakasununguka nezvayo. Chiedza chakatariswa chine simba rinoshamisa. Chero ani zvake ari padyo nekuvhiya anofanira kupfeka akasarudzika laser kuchengetedza magirazi akatemerwa iwo chaiwo wavelength yelaser yako.
Ko Laser Welding Machine ndiyo Sarudzo Yakakukodzera Iwe?
Saka, iwe unofanirwa kuisa mari mune laser welding?
Ngatidzokororei. Laser welding chishandiso chepamusoro chekugadzira chinopa kukurumidza kusingaenzaniswi, kunyatsojeka, uye mhando. Kutengeserana ndiko kudhura kwekutanga uye zvinodikanwa zvakasimba zvezvikamu zvakachena, zvinokwana.
Pfungwa yedu yekupedzisira: Kana basa rako richida vhoriyamu yakakwira, otomatiki, uye nekunongedza chaiko-kunyanya pazvinhu zvakapfava kana zvinonetsa-ipapo laser welding haisi imwe sarudzo. Ndiyo mhinduro yepamusoro inogona kushandura kugadzirwa kwako.
