Kusarudza iyo chaiyo laser welding inobatsira gasi ndeimwe yesarudzo dzakanyanya kukosha dzauchaita, asi kazhinji hazvinzwisiswe. Wakambozvibvunza here kuti sei iyo inoratidzika kunge yakakwana laser weld yakakundikana pasi pekunetseka? Mhinduro inogona kunge iri mumhepo… kana kuti, mune chaiyo gasi yawaishandisa kudzivirira weld.
Iri gasi, rinodaidzwawo kuti shielding gasi relaser welding, haingori sarudzo yekuwedzera; chikamu chakakosha chemaitiro. Inoita mabasa matatu asingakurukurirwe anotarisisa kunaka, simba, uye kutaridzika kwechigadzirwa chako chekupedzisira.
Inodzivirira Weld:Gasi rinobatsira rinogadzira bubble rekudzivirira rakatenderedza simbi yakanyungudutswa, richiidzivirira kubva kumagasi emuchadenga akaita seokisijeni nenitrogen. Pasina nhovo iyi, unowana hurema hwakaipa senge oxidation (isina simba, isina mavara weld) uye porosity (mabhuru madiki anokanganisa simba).
Iyo Inovimbisa Yakazara Laser Simba:Sezvo laser inorova simbi, inogona kugadzira "plasma gore." Iri gore rinogona kuvharira nekuparadzira simba re laser, zvichitungamira kune isina kudzika, isina simba welds. Iyo gasi rekurudyi inovhuvhuta iyi plasma kure, kuve nechokwadi chekuti simba rakazara relaser yako rinosvika kune workpiece.
Inodzivirira Chishandiso Chako:Rukova rwegasi zvakare runodzivirira simbi mhute uye spatter kubva kubhururuka kumusoro uye kusvibisa inodhura inotarisisa lens mumusoro wako laser, ichikuchengetedza kubva kunodhura kudzika uye kugadzirisa.
Kusarudza Shielding Gasi reLaser Welding: The Main Contenders
Sarudzo yako yegasi inodzika kusvika kune vatatu vatambi: Argon, Nitrogen, uye Helium. Funga nezvavo semazvikokota akasiyana aungatsvaga basa. Imwe neimwe ine yakasarudzika masimba, kushaya simba, uye yakakodzera makesi ekushandisa.
Argon (Ar): Iyo Yakavimbika Yese-inotenderera
Argon ndiye bhiza rekushanda renyika yewelding. Igasi inert, zvichireva kuti haizopindirana nedziva rekunyungudutswa. Iyo zvakare inorema kupfuura mhepo, saka inopa yakanakisa, yakagadzikana yekudzivirira yekuvhara isingade yakawandisa yakakwirira kuyerera.
Zvakanakira:Huwandu hwakakura hwezvinhu, zvinosanganisira aluminium, simbi isina tsvina, uye kunyanya reactive simbi setitanium. Argon laser welding ndiyo yekuenda kune fiber lasers nekuti inopa yakachena, inopenya, uye yakatsetseka weld kupera.
Kufunga Kwakakosha:Iyo ine yakaderera ionization inogona. Iine yakanyanya-simba-CO₂ lasers, inogona kubatsira mukuumbwa kweplasma, asi kune mazhinji emazuva ano fiber laser application, ndiyo sarudzo yakakwana.
Nitrogen (N₂): Muiti Anodhura
Nitrogen ndiyo inosarudzika bhajeti, asi usarega mutengo wakaderera uchikunyengedza. Mukushandisa kwakakodzera, haisi nhovo chete; mutori wechikamu anoshanda anogona kunyatso vandudza weld.
Zvakanakira:Mamwe mamakisi esimbi isina tsvina. Kushandisa nitrogen yelaser welding simbi isina tsvina inogona kuita sealloying alloying, kudzikamisa simbi yemukati chimiro kuvandudza mechanical simba uye corrosion resistance.
Kufunga Kwakakosha:Nitrogen igasi rinoshanda. Kuishandisa pane zvisiri izvo, setitanium kana mamwe masimbi ekabhoni, inzira yenjodzi. Ichaita nesimbi uye inokonzera kukanganisa kwakanyanya, zvichiita kuti weld inogona kuputika uye kukundikana.
Helium (Iye): Nyanzvi Yepamusoro-Kushanda
Helium ndiyo nyeredzi inodhura. Iyo ine yakanyanya kupisa yekupisa conductivity uye inoshamisa yakakwira ionization inogona, ichiita iyo isinga pikisa shasha yekudzvinyirira kweplasma.
Zvakanakira:Yakadzika yekupinda welding mune gobvu kana zvakanyanya conductive zvinhu sealuminium nemhangura. Iyo zvakare isarudzo yepamusoro yeakakwira-simba CO₂ lasers, ayo anotapurirana zvakanyanya neplasma kuumbwa.
Kufunga Kwakakosha:Mutengo. Helium inodhura, uye nekuti yakareruka, unoda mafambiro epamusoro kuti uwane dziviriro yakakwana, zvichiwedzera kuwedzera mutengo wekushanda.
Quick-Reference Gasi Kuenzanisa
| Gasi | Primary Function | Mhedzisiro paWeld | Common Use |
| Argon (Ar) | Shields weld kubva kumhepo | Yakanyanya inert kune yakachena weld. Nzira yakagadzikana, chimiro chakanaka. | Titanium, Aluminium, Stainless Simbi |
| Nitrogen (N₂) | Inodzivirira oxidation | Inodhura-inoshanda, kupera kwakachena. Inogona kuita mamwe simbi brittle. | Stainless Simbi, Aluminium |
| Helium (Iye) | Kupinda kwakadzika & kudzvanywa kweplasma | Inobvumira kudzika, yakafara welds nekumhanya kukuru. Zvinodhura. | Zvinhu zvakakora, Mhangura, High-simba welding |
| Gasi Misanganiswa | Zviyero mutengo & kushanda | Inosanganisa mabhenefiti (semuenzaniso, kugadzikana kwaAr + Iye kupinda). | Chaiyo alloys, optimize weld profiles |
Inoshanda Laser Welding Gasi Sarudzo: Kufananidza Gasi neSimbi
Dzidziso yakanaka, asi unoishandisa sei? Heino dhairekitori rakatwasuka rezvinhu zvakajairika.
Welding Stainless Simbi
Iwe une sarudzo mbiri dzakanakisa pano. Kune austenitic uye duplex Stainless steels, Nitrogen kana Nitrogen-Argon musanganiswa kazhinji ndiyo inosarudzwa yepamusoro. Iyo inosimudzira iyo microstructure uye inowedzera simba re weld. Kana chako chekutanga chakanyatso kuchena, kupenya kupedzisa pasina kusangana kwemakemikari, yakachena Argon ndiyo nzira yekuenda nayo.
Welding Aluminium
Aluminium inonetsa nekuti inobvisa kupisa nekukurumidza. Kune akawanda maapplication, yakachena Argon ndiyo yakajairwa sarudzo nekuda kwekudzivirira kwayo kwakanaka. Nekudaro, kana uri welding gobvu zvikamu (pamusoro 3-4 mm), musanganiswa weArgon-Helium inoshandura mutambo. Iyo helium inopa iyo yekuwedzera yekupisa punch inodiwa kuti uwane yakadzika, inopindirana kupinda.
Welding Titanium
Pane mutemo mumwechete we welding titanium: shandisa yakakwirira-kuchena Argon. Usambofa washandisa Nitrogen kana chero musanganiswa wegasi une magasi anoshanda. Nitrogen ichaita netitanium, ichigadzira titanium nitrides inoita kuti weld iite brittle uye inotarisirwa kukundikana. Yakakwana kudzivirira ine trailing uye kutsigira gasi zvakare inosungirwa kuchengetedza simbi inotonhorera kubva kune chero kusangana nemhepo.
Nyanzvi Zano:Vanhu vanowanzo edza kuchengetedza mari nekudzikisa gasi ravo rekuyerera, asi ichi chikanganiso chekare. Mutengo weiyo imwe chete yakatadza weld nekuda kweoxidation inodarika mutengo wekushandisa iyo chaiyo huwandu hwekudzivirira gasi. Gara uchitanga neyakakurudzirwa kuyerera kwechikumbiro chako uye gadzirisa kubva ipapo.
Troubleshooting Common Laser Welding Defects
Kana iwe uchiona matambudziko mune ako welds, yako yekubatsira gasi ndechimwe chezvinhu zvekutanga zvaunofanira kuongorora.
Oxidation & Discoloration:Ichi ndicho chiratidzo chiri pachena chekudzivirira kusina kunaka. Gasi rako harisi kudzivirira weld kubva kuokisijeni. Iyo gadziriso inowanzo wedzera yako gasi kuyerera mwero kana kutarisa muromo wako uye gasi rekutumira system yekuvuza kana kuvharika.
Porosity (Gasi Bubbles):Kukanganisa uku kunopedza simba weld kubva mukati. Inogona kukonzerwa nekuyerera kwakadzikira (hakuna dziviriro yakakwana) kana imwe yakanyanya kukwirisa, inogona kukonzeresa nyonganyonga uye kukwevera mweya mudziva reweld.
Kupinda Kusingaenderani:Kana yako weld kudzika kuri kwese kwese, unogona kunge uchibata neplasma ichivharira laser. Izvi zvakajairika neCO2 lasers. Mhinduro ndeyekuchinja kune gasi rine nani plasma kudzvinyirira, seHelium kana Helium-Argon musanganiswa.
Misoro Yakadzama: Gasi Musanganiswa & Mhando dzeLaser
Simba re Strategic Mixtures
Dzimwe nguva, gasi rimwe chete harina kunyatsoricheka. Musanganiswa wegasi unoshandiswa kuwana "zvakanakisa zvepasirese."
Argon-Helium (Ar/He):Inosanganisa kudzivirira kwakanakisa kweArgon nekupisa kwakanyanya uye plasma kudzvanywa kweHelium. Yakakwana kune yakadzika welds mualuminium.
Argon-Hydrogen (Ar/H₂):Huwandu hushoma hwehydrogen (1-5%) hunogona kuita “semugadziri wekudzikisa” pasimbi isina tsvina, huchikwenya okisijeni yakarasika kuti ibudise yakatojeka, yakachena weld bead.
CO₂ vs.Fiber: Kusarudza Yakarurama Laser
CO₂ Lasers:Ivo vanonyanya kunetseka nekuumbwa kweplasma. Ichi ndicho chikonzero Helium inodhura yakajairika mune yakakwirira-simba CO2 applications.
Fiber Lasers:Ivo havana kunyanya kutarisana nenyaya dzeplasma. Iri bhenefiti rakanaka rinokutendera kuti ushandise mamwe anodhura-anoshanda magasi seArgon neNitrogen kune akawanda akawanda emabasa pasina kupira kuita.
The Bottom Line
Kusarudza laser welding inobatsira gasi chinhu chakakosha maitiro parameter, kwete yekuzofunga. Nekunzwisisa mabasa akakosha ekudzivirira, kuchengetedza maziso ako, uye kudzora plasma, unogona kuita sarudzo ine ruzivo. Gara uchifananidza gasi kune zvinhu uye izvo zvinodikanwa zvekushandisa kwako.
Wakagadzirira kukwirisa yako laser welding process uye kubvisa gasi-ane hukama hurema? Ongorora yako gasi sarudzo yazvino uchipesana nemirairo iyi uye ona kana shanduko iri nyore inogona kutungamira mukuvandudzika kukuru kwemhando nekubudirira.
