Yakanaka mhedzisiro yeiyo yakakodzera nhoo gasi
MuLaser Welding, sarudzo yegesi yekudzivirira inogona kuve nehunhu hwakakosha pane kuumbwa, hunhu, hwakadzika, uye hwakafara hweSEAM. Muhuwandu hwematare, iyo yekutanga yegesi yekudzivirira ine mhedzisiro yakanaka paSeam SEAM. Nekudaro, zvinogona zvakare kuve nemhedzisiro yakaipa. Mhedzisiro yakanaka yekushandisa iyo chaiyo yekudzivirira gasi ndeye inotevera:
1. Kubudirira Kudzivirirwa kweiyo Weld Pool
Nhungamidzo yakakodzera yegesi yekudzivirira inogona kudzivirira nhoo inobudirira dziva kubva kune oxidation kana kunyange kudzivirira oxidation zvachose.
2. Kuderedzwa kwekutsvuka
Nenzira chaiyo kuunza gasi rekudzivirira kunogona kuderedza zvinobudirira kupuruzira panguva yekuita macomputer.
3. Yunifomu Yemukati yeWell seam
Nhungamidzo yakakodzera yegesi yekudzivirira inosimudzira iyo ichitotarisana neiyo yeWeld Pool panguva yekusimbisa, zvichikonzera yunifomu uye ainthetically inofadza weld seam.
4. yakawedzera laser kushandiswa
Nenzira chaiyo kuunza gasi rekudzivirira kunogona kuderedza zvinobudirira maitiro ekuchengetera simbi mupasuru pendi kana plasma makore pane laser, nekudaro achiwedzera kushanda kweiyo laser.
5. Kuderedza kweWeld Porosity
Nenzira chaiyo kuunza gasi rekudzivirira kunogona kuderedza zvinobudirira kuumbwa kwegasi pores mune weld seam. Nekusarudza iyo yakakodzera gasi mhando, kuyerera, uye nzira yekuunzwa, mhedzisiro yakakodzera inogona kuwanikwa.
Nekudaro,
Kushandisa zvisina kufanira kwegasi rekudzivirira kunogona kuve nemhedzisiro yekukanganisa paWelding. Mhedzisiro yakaipa inosanganisira:
1. Kuora kweiyo weld seam
Nhungamidzo isiriyo yegasi yekudzivirira inogona kukonzera murombo weld seam mhando.
2. Kupwanya uye kuderedzwa mechanical zvivakwa
Kusarudza mhando isiriyo yegesi kunogona kutungamira kune weld seam kupaza uye kuderedza meheti kuita.
3. yakawedzera oxidation kana kupindira
Kusarudza iyo isiriyo gasi kuyerera chiyero, kunyangwe yakanyanya kukwirisa kana yakaderera, inogona kutungamira kune yakawedzera oxidation yeiyo weld seam. Izvo zvinogona zvakare kukonzera nyonganiso yakasimba kune yakanyungudutswa simbi, zvichikonzera kudonha kana kugadzirwa zvisina kufanana kweSEAM SEAM.
4. Isina kukwana kuchengetedzwa kana kukanganisa kwakashata
Kusarudza nzira isiriyo yegesi yekunyepedzera inogona kutungamira kune isina kukwana kuchengetedzwa kweiyo weld seam kana kunyange kuve neisina kunaka mhedzisiro pakuumbwa kweSEAM.
5. Simba paWeld Yakadzika
Nhungamiro yegesi yekudzivirira inogona kuve neyakaoverana pane kudzika kweiyo weld, kunyanya muutete wakarukwa tete, uko kunowanzo kuderedza pakadzika kweWalk.

Mhando dzemagasi anodzivirira
The commonly used protective gases in laser welding are nitrogen (N2), argon (Ar), and helium (He). Aya magasi ane akasiyana emuviri uye makemikari zvivakwa, izvo zvinoguma nemhedzisiro dzakasiyana paSeam SEAM.
1. Nitrogen (N2)
N2 ine simba rine mwero ionization, yakakwirira kupfuura ar uye yakaderera kupfuura iye. Pasi pechiitiko che laser, iyo inosimbisa degree rine mwero, nekudzora zvinobudirira kuumbwa kwemakore eplasma uye kuwedzera iyo laser yekushandisa. Nekudaro, nitrogen inogona kuita nemakemikari neAluminium alloys uye carbon simbi pane mamwe tembiricha, achiumba nitides. Izvi zvinogona kuwedzera iyo brittleness uye kuderedza kuomarara kweSEAM SEAM, zvisizvo zvinokanganisa zvimiro zvaro zvemakaniki. Naizvozvo, kushandiswa kweNitrogen segesi yekudzivirira yeAluminium Alloys uye carbon Steel Wels haina kukurudzirwa. Kune rimwe divi, nitrogen inogona kuita nesimbi isina tsvina, ichigadzira nitritside inosimudzira simba reWelks of Wel. Naizvozvo, nitrogen inogona kushandiswa segasi rinodzivirira rekushandisa simbi isina tsvina.
2. Argon gasi (ar)
ARGON Gasi ine yakaderera ionization simba, inokonzeresa mune yakakwirira mwero weionization pasi peLaser chiito. Izvi hazviratidzi kudzora kuumbwa kwemakore eplasma uye anogona kuve nezvokuita zvimwe zvinokonzeresa zvinoshandiswa zvinoshandiswa. Nekudaro, Argon ine yakaderera yekugadzirisa uye haifungidzirwe kuti ishandiswe yemakemikari ane mitezo yakajairika. Uyezve, Argon mutengo-unobata. Uyezve, nekuda kwekushomeka kwaro kwakakwirira, Argon anonyura pamusoro pePava weld, ichidzivirira zviri nani padziva reWeld. Naizvozvo, inogona kushandiswa seganda reunyanzvi hwekuchengetedzeka.
3. Helium gasi (iye)
Helium gasi ine iyo yepamusoro yeionization simba, inotungamira kune yakaderera kwazvo degree reionization pasi peLaser chiito. Inotendera kudzora zviri nani zvePlasma gore kuumbwa, uye lasers vanogona kubata zvinobudirira nesimbi. Uyezve, helium ine chekuita zvakanyanya uye haina kujairika kuita zvemakemikari nekushungurudzika, ichiita gasi rakanakisa rekuchengetedza. Nekudaro, mutengo weHelium wakakwira, saka kazhinji hazvishandiswe mukugadzirwa kukuru kwezvigadzirwa. Iyo inowanzo shandiswa mukutsvaga kwesainzi kana kune yakakwirira-kukosha-yakawedzerwa zvigadzirwa.

Nzira dzekusuma gasi rekuchengetera
Parizvino, pane nzira mbiri huru dzekusuma gasi rekuchengetera: Off-axis rutivi kuputika uye coaxial scirsing gasi, sezvakaratidzwa mumufananidzo 1 uye mufananidzo 2, zvichiteerana.
Mufananidzo 1: Off-axis chikamu chinoputika gasi rekunyepedzera
Mufananidzo 2: Coaxial Kuchengetedza Gasi
Sarudzo pakati penzira mbiri dzekuputika dzinoenderana nekufunga kwakasiyana siyana. Kazhinji, zvinokurudzirwa kushandisa iyo off-axis chikamu chinoputika nzira yekuchengetedza gasi.

Nheyo dzekusarudza nzira yekuunza gasi rekuchengetera
Chekutanga, zvakakosha kujekesa kuti izwi rekuti "oxidation" reruzi chiratidzo chekodhi. Mufundisi, zvinoreva kudzikira kwemhando yeWeld nekuda kwekusaita kwemakemikari pakati peiyo marefu mhepo uye inokuvadza zvinhu mumhepo, yakadai seokisijeni, nitrogen, uye hydrogen.
Kudzivirira Well Oxidation kunosanganisira kudzikisira kana kudzivisa kusangana pakati pezvikamu izvi zvinokuvadza uye iyo yakakwira-tembiricha yemasimbi. Iyi nyika yakakwirira-tembiricha inosanganisira kwete chete iyo yakanyungudutswa yedanda simbi asiwo nguva yese kubva apo iyo weld simbi ichinyungudika kusvikira dziva uye tembiricha yayo inoderera pazasi chimwe chikumbaridzo.
Semuenzaniso, muAlting of Titanium ATLOYS, apo tembiricha iri pamusoro pe300 ° C, Rapid Hydrogen Toption inoitika; Pamusoro 450 ° C, Rapid oksijeni yekunyora inoitika; Uye pamusoro pe600 ° C, Rapid nitrogen kushamisika kunoitika. Naizvozvo, dziviriro inoshanda inodiwa kuti Titanium Alloy Weld panguva iyo chikamu chichivhara uye tembiricha yayo inoderera pazasi 300 ° C kudzivirira oxidation. Zvichienderana nerondedzero iri pamusoro, zviri pachena kuti gasi rekuchengetedzeka kwegasi rinoda kupa dziviriro kwete chete kune imwe nzvimbo yeWeld panguva yakakodzera asiwo kune nzvimbo yakasarudzika yeWelt. Nekudaro, iyo-axis chikamu chinoputika nzira inoratidzwa mumufananidzo Nekudaro, kune zvimwe zvigadzirwa zvakati, sarudzo yemaitiro anoda kuitwa zvichienderana nechero zvigadzirwa uye kubatana.

Kusarudzwa kwakananga kwenzira yekuunza gasi rekuchengetera
1. Rakananga-mutsara weld
Kana iyo yechigadzirwa yeld chimiro yakatwasuka, sezvakaratidzwa mumufananidzo 3, uye kuunganidzwa kwakabatana kunosanganisira butt majoini, fillet welts, iyo nzira yaunosarudza yerudzi urwu rwechigadzirwa ndeyekunze Mufananidzo 1.
Mufananidzo 3: Rwakananga-mutsara weld
2. Chirongwa chakavharirwa geometry weld
Sezvinoratidzwa mumufananidzo 4, weld mune iyi mhando yechigadzirwa ine yakavharwa chirongwa chimiro, senge denderedzwa, polygonal, kana yakawanda-chikamu mutsara mutsara. Iyo yekubatanidza yakabatana inogona kusanganisira butt majoini, majoini majoini, kana stack welds. Kune rudzi urwu rwechigadzirwa, nzira inosarudzwa ndeyekushandisa iyo coxial yekuchengetedza gasi inoratidzwa mumufananidzo 2.
Mufananidzo 4: Planar yakavharirwa Geometry Weld
Kusarudzwa kwegesi yekuvhara kwegero yehurongwa yakavharirwa geometry inobata zvakananga kubata kunaka, kushanda zvakanaka, uye mutengo wekugadzira kugadzirwa. Nekudaro, nekuda kwekusiyana-siyana kwezvinhu zvakasikwa zvekushandisa, kusarudzwa kwekutengesa gasi kuomarara muCompating maitiro. Zvinoda kutarisisa kutarisisa kwekutarisa zvinhu, nzira dzinotambudza, dzinotsvedza zvinzvimbo, uye mhedzisiro yaunoda. Iko kusarudzwa kweiyo yakakodzera yelting gasi inogona kutsanangurwa kuburikidza neyekutarisa miedzo kuti uwane yakakwana yehutachiona.
