Umshini Wokushisela We-Laser Ophathekayo Wokwenziwa Kwe-Aluminium: Okufanele Ukwazi

Umhlahlandlela Wezobuchwepheshe

Ukuthi Kungani Ukuthwaleka Kubalulekile Ekwakheni I-Aluminium

Izitolo zokwakha i-aluminium zisingatha izinhlobonhlobo zezingxenye zomsebenzi - kusukela kumashidi ayisicaba namaphrofayili ahlanganisiwe kuya ezinhlakeni ezinkulu zokwakha nama-assemblies enziwe ngokwezifiso. Akukho ngisho nengxenye eyodwa engathuthwa esiteshini sokushisela esimile. Umshini wokushisela we-laser ophathwayo wokwakha i-aluminium uletha i-weld emsebenzini, ususa isidingo sokuphinda ubeke izinto ezisindayo noma ezinkulu kakhulu futhi unciphise ukulimala kokuphatha ezingaphezulu eziqediwe.

Ukushintsha kusuka ekushiseleni kwendabuko kwe-TIG noma MIG kuya ku- umshini wokushisela nge-laser ophathwayo kushintsha ukuhamba komsebenzi wokwakha ngezindlela eziningi ezisebenzayo: ijubane lokuhamba elisheshayo, izindawo ezincane ezithintekile ukushisa, ukugaya okuncane ngemva kwe-weld, nokukwazi ukushisela ubukhulu obuhlukile ekusethweni okukodwa. Ukuze uthole ukubuka okuphelele, hlola umhlahlandlela wethu wokukhetha i- umshini wokushisela nge-laser ophathwayo we-aluminium.

Yini Echaza Uhlelo Lokushisela Nge-Laser Oluthwalekayo

Ukuthwaleka kumongo wama-welders e-fiber laser aphathwayo kusho ukuthi uhlelo oluphelele - umthombo we-laser, iyunithi yokupholisa ngamanzi, uhlelo lokulawula, nesibhamu sokushisela - kungathuthwa endaweni yomsebenzi futhi kumiswe ngemizuzu embalwa. Izici ezibalulekile zomugqa wethu wemikhiqizo:

Amamodeli angu-1000 W no-1500 W ngawona asetshenziswa kakhulu ezitolo zokwakha eziphatha amaphrofayili e-aluminium, izindlu zensimbi, nama-assemblies ezakhiwo. Amamodeli angu-2000 W no-3000 W asebenzela izidingo ezisindayo zokwakha njengama-extrusions anezindonga ezijiyile namajoyinti anezendlalelo eziningi.

Izicelo Zokwakha I-Aluminium

Amaphrofayili Ezakhiwo kanye Nezinto Ezikhishwayo

I-aluminium extrusions - amaphrofayili e-T-slot, amashubhu angunxande, kanye nezigaba ezingokwezifiso - ayinsika yamafreyimu, izindawo ezivalekile, nezakhiwo zokusekela. I-handheld laser welding ifaneleka kahle kumajoyinti amakhona, amajoyinti e-T, kanye nama-node amalungu amaningi ngoba i-beam egxilile ikhiqiza i-weld ewumngcingo, ejulile enokushintshwa okuncane kokushisa. Lokhu kubaluleke kakhulu emihlanganweni enembile lapho ukubekezelela kokucwenga kwangemva kokuwelda kuqinile.

Izindawo Ezivalekile Zensimbi Eziyizingqimba

Kuma-enclosure akhiwayo - izindlu zikagesi, amabhokisi ebhethri, namaphaneli okulawula - i-handheld laser welder ikhiqiza ama-weld ahlanzekile, amukelekile ngobuhle ngokuvamile angadingi ukuqedwa okwengeziwe. I-HAZ ewumngcinga (ngokuvamile 0.5–1.5 mm) igcina ukucaba kwamaphaneli aseduze, okubalulekile ekuvaleni kwe-enclosure nasekufakweni kwegasket.

Ama-Heat Exchanger kanye nama-Tube-to-Sheet Joints

Ama-heat exchanger e-aluminium adinga amajoyinti e-tube-to-sheet anokungena okugcwele nokungavuzi. Ukulawulwa kokushisa okulawulwayo kwe-fiber laser, kuhlanganiswe nekhono lesistimu yokupholisa ngamanzi lokugcina ukuphuma okuzinzile ngaphezu kwamahora angu-8, kukwenza kusebenze ekukhiqizeni ngobuningi kwala majoyinti adingekayo.

Ukulungisa Nokwenza Kabusha

Ezindaweni zokwakha, umshini we-laser welding ophathwayo nawo ubalulekile ekulungiseni izingxenye ze-aluminium ezilimele endaweni - imifantu ezingxenyeni zezakhiwo, izindawo zokuhlangana ezigugile, nokwenza kabusha ama-weld anesici. Ikhono lokuthwala isibhamu sokuwelda siye endaweni yokulungisa, kunokuba sihlukanise isakhiwo, konga isikhathi esiningi sokusebenza.

Okubalulekile Okucatshangelwayo Emisebenzini Yokukhiqiza

Ukuhambisana Kwe-alloy

Izindawo zokukhiqiza zivame ukusebenza nama-aluminium alloys amaningi. Ukuqonda ukuthi ngalinye liphendula kanjani ku-laser welding kubalulekile:

Ukuphathwa Kwe-Oxide Layer Ekukhiqizeni

Esitolo sokukhiqiza, izingxenye ze-aluminium zingahlala amahora noma izinsuku phakathi kokusika nokuwelda. I-oxide layer iyakhula ngokuhamba kwesikhathi, ikhule isuka kuma-nanometer ambalwa iye kuma-micrometer amaningi. Lolu oxide layer oluwugqinsi luphakamisa umkhawulo wokuncibilika futhi lungabangela ukukhubazeka kwe-weld. Imikhuba ebalulekile:

• Susa i-oxide ngomshini (ngebhulashi lensimbi engagqwali) noma ngamakhemikhali (ngokuklwebha) phakathi kwamahora angu-4 okuwelda.
• Ezingxenyeni ezigciniwe, hlela ukususwa kwe-oxide njengesinyathelo sokugcina ngaphambi kokuwelda.
• Hlola imiphetho esikiwe - imiphetho ye-aluminium esikwe nge-laser ingase ibe ne-recast oxide layer edinga ukugaywa ngaphambi kokuwelda.

I-Shielding Gas Ezimweni Zasendle

Uma usebenzisa umshini we-laser welding ophathwayo wokukhiqiza i-aluminium ezindaweni ezivulekile noma ezivalekile kancane, ukusebenza kwe-shielding gas kungaphazanyiswa ukunyakaza komoya. Izinyathelo ezisebenzayo:

• Khuphula izinga lokugeleza kwegesi ngo-20–30% uma kuqhathaniswa nokuwelda endaweni yokusebenza yangaphakathi.
• Sebenzisa i-gas lens nozzle ukuze uthole ukumboza okulaminar, okubanzi.
• Gwema ukuwelda emoyeni oqondile; sebenzisa izikrini noma izindawo ezivalekile lapho kudingeka.
• Kumajoyinti abalulekile, cabanga nge-trailing shield ukuze uvikele i-weld bead eqinile.

Izinzuzo Zokukhiqiza Ngaphezu Kwezindlela Zendabuko

Uma kuqhathaniswa nokuwelda kwe-TIG kwe-aluminium, i-handheld fiber laser welder ngokuvamile ithola isivinini sokuhamba esiphindwe ka-3–5 ngenkathi ikhiqiza i-HAZ ewumngcinga futhi idinga ukuhlanzwa okuncane kwangemva kokuwelda. Isistimu yokupholisa ngamanzi isekela ukusebenza okuqhubekayo kwamahora angu-8+, okusho ukuthi umsebenzi oyedwa angaqeda imisebenzi emide yokukhiqiza ngaphandle kokuma ukuze imishini iphole. Ukungaguquguquki kwe-weld seam engu-±0.1 mm kunciphisa isikhathi sokwenza kabusha nokuhlola.
