Laser Welding inonyanya kuvandudzwa pakuvandudza iyo yekubata uye mhando yemidziyo yakatetepa yemadziro uye zvikamu zvakanyanyisa. Nhasi hatisi kuzotaura nezvezvakanakira zve laser welder asi tarisa maitiro ekushandisa magedhi ekurasa kumeso kweLaser ally nemazvo.
Nei usingashandise nhoo gasi ye laser welder?
MuLaser Weldinging, gasi nhepirhi inokanganisa weld yekuumba, Weld hunhu, weld kudzika, uye wezvipenyu. Muzhinji, kuridza gasi rakabatsirwa richava nemhedzisiro yakanaka paWeld, asi inogona zvakare kuunza mhedzisiro yakaipa.
Paunoputira pasirese sosi nenzira kwayo, ichakubatsira:
✦Zvinobudirira chengetedza iyo weld mudzime kuti udzikise kana kutodzivisa oxidation
✦Zvinobudirira kuderedza iyo Splash yakagadzirwa muCustoming maitiro
✦Zvinobudirira kuderedza maWell emores
✦Batsira iyo Weld Pool yakapararira kana kusimbisa, kuitira kuti seam yeWeld inosvika nemucheto wakachena uye hwakatsiga
✦Iko kusiya simba kweiyo simbi mupendero kana Plasma gore pane laser inoderedzwa nenzira yakakodzera, uye iyo inoshanda inoshanda yeiyo laser inowedzera.
Chero bedziShiel Shiely mhando, gasi kuyerera chiyero, uye kuputika mode kusarudzwandizvozvo, iwe unogona kuwana iyo yakakodzera mhedzisiro yeWelding. Nekudaro, kushandisa zvisiri izvo kwegesi yekudzivirira kunogona zvakare kukanganisa nzizi. Uchishandisa mhando isiriyo yegasi pasifa nhofisi inogona kutungamira kune craks muWeld kana kuderedza michina yemuchina yeiyo nongororo. Yakanyanya kukwirira kana kuderera kuyerera kwegasi kuyerera kunogona kutungamira kune yakakomba teld olid
Mhando dzeGasi Shower
Iwo anowanzo shandiswa magasi anodzivirira eLaser Welding ari kunyanya N2, AR, uye iye. Zvivakwa zvavo zvemuviri uye zvemakemikari zvakasiyana, saka mhedzisiro yavo pamabhekita zvakare akasiyanawo.
Nitrogen (N2)
Iyo ionization simba reN2 iri pakati nepakati, yakakwirira kupfuura iyo yeAR, uye yakaderera kupfuura iyo yaAri. Pasi peiyo radiation ye laser, iyo ionization mwero weN2 inogara pane imwe keel, iyo inogona kuderedza kuumbwa kwegore replasma uye kuwedzera huwandu hwekushandiswa kweiyo laser. Nitrogen inogona kuita neAluminium Alloy uye carbon simbi kune imwe tembiricha yekugadzira notritles, iyo ichavandudza brittleness uye kuderedza kuomarara, uye kuve nekukanganisa kwakashata pazvinhu zvekugadzira majini elD majoini. Naizvozvo, hazvikurudzirwe kushandisa nitrogen kana tilding aluminium Alloy uye carbon simbi.
Nekudaro, maitiro emakemikari pakati peNitrogen uye STOLLUT STECHE ANOGADZIRA NEZVINHU ZVINOGONESESA ZVAKAITWA ZVESE, SEATE YEMUKADZISI WEMAHARA.
Argon (ar)
Simba reIonization yeArgon rakadzika kwazvo, uye mwero wayo weionization wacho uchave wakakwira pasi pechiitiko che laser. Ipapo, Argon, segasi rekuchengetedza, harigone kudzora zvinobudirira kuumbwa kwemakore eplasma makore, ayo anozodzora huwandu hunobudirira hwekushandiswa kweLaser welas. Mubvunzo unomuka: Is Argon mutsetse wakashata wekushandiswa nekushandisa gasi rekuchengetera? Mhinduro yacho ndeye Kwete Mukuwedzera, dentity yeAR yakakura, ichaita kuti kunyura kumusoro kweiyo Welth mudzidzi yakaumbwa uye inogona kudzivirirwa dziva remukati reWeld, saka Argon inogona kushandiswa segasi rinowanzochinja.
Helium (iye)
Kusiyana neAlgon, helium ine simba rakakwirira yeionization iyo inogona kudzora kuumbwa kwemakore eplasma zviri nyore. Panguva imwecheteyo, Herium haiite nemagariro. Ichokwadi chisarudzo chakanaka cheLaser Welding. Dambudziko chete nderekuti herium rinodhura. Kune machira anopa huwandu hwezvigadzirwa zvesimbi, helium uchawedzera huwandu hwakakura pamubhadharo wekugadzira. Nekudaro helium inowanzoshandiswa mukutsvaga kwesainzi kana zvigadzirwa zvine yakakwirira kwazvo yakawedzera kukosha.
Kurova sei gasi renhi?
Chekutanga pane zvese, zvinofanirwa kuve zvinonzi "oxidation" yeWels inongori zita rakajairika, iro rinoreva nezveMakemikari Ekuita Pakati peAld uye zvinhu zvinokuvadza mumhepo, zvichitungamira mukuora kweWeld . Kazhinji, iyo simbi yeLD inoshanda neokisijeni, nitrogen, uye hydrogen mumhepo pane imwe tembiricha.
Kudzivirira weld kubva kune "oxided" inoda kudzikisira kana kudzivisa kusangana pakati pezvikamu zvakashata, izvo zvisingamonesera mongororo yakadzika asi nguva yese kubva panguva iyo simbi yakamonyaniswa kusvika Molten Dool Metal inosimbisa uye tembiricha yayo inotonhorera pasi kune imwe tembiricha.

Iko kusarudzwa kwakananga kwemafambiro maviri ekuridza kuridza kufunga kwakazara kwezvinhu zvakawanda. Kazhinji, zvinokurudzirwa kutora nzira yegasi rinovhuvhuta gasi rekudzivirira.
Mimwe mienzaniso ye laser welder
1. Kutwasuka Bead / Mutsetse Welding
Sezvinoratidzwa mumufananidzo 3, iyo weld chimiro chechigadzirwa chiri mutsara, uye fomu yakabatanidzwa inogona kunge iri butt yakabatanidzwa, yakabatanidzwa, yakabatana kona, kana yakangoita yakabatanidzwa, kana yakafukidzwa yakabatanidzwa. Kune rudzi urwu rwechigadzirwa, zviri nani kutora chikamu-axis kuputika gasi rekudzivirira sezvakaratidzwa mumufananidzo 1.
2. Pedyo nhamba kana nharaunda Welding
Sezvinoratidzwa mumufananidzo 4, iyo weld chimiro chechigadzirwa ndiyo nzira yakavharwa sedzenzvimbo Zviri nani kutora iyo coaxial inodzivirira gasi nzira sezvakaratidzwa mumufananidzo 2 yeiyi mhando yechigadzirwa.
Kusarudzwa kwegasi kudzivirira kwegasi zvakananga, kushanda zvakanaka, uye mutengo wekugadzira kwezvinhu zvakasikwa, mukusarudzwa kwegasi kune zvakaoma uye zvinoda kutaridzika kwekutarisa zvinhu, Welding Nzira, Welding chinzvimbo, pamwe nezvinodiwa zvekutora mari. Kuburikidza nemuedzo weWelding, unogona kusarudza iyo yakanyanya kukodzera gasi gasi kuwana mhedzisiro iri nani.
Kufarira laser weldering uye kuda kudzidza maitiro ekusarudza sosi gasi
