Ni ubuhe bwoko bwa lazeri yo gusudira uzi?

Ibyiza nibibi bya Laser Welding ya Aluminium Alloy

Iyo laser yo gusudira aluminiyumu, kimwe no gusudira ibyuma bya galvanis, ibyuma byinshi nibisatura bizakorwa mugihe cyo gusudira, bizagira ingaruka kumiterere yo gusudira.Ikintu cya aluminiyumu gifite ingufu nkeya za ionisiyoneri, umutekano muke wo gusudira, kandi bizanatera guhagarika gusudira.Usibye uburyo bwo gusudira ubushyuhe bwinshi, azide ya aluminium na nitride ya aluminium bizakorwa mubikorwa byose, bitera umwanda ibidukikije.

Nyamara, isahani ya aluminiyumu irashobora guhanagurwa mbere yo gusudira kugirango yongere imbaraga zayo za laser;Gazi ya inert igomba gukoreshwa mugihe cyo gusudira kugirango hirindwe umwobo.

Laser arc hybrid welding ya aluminiyumu yakemuye ibibazo byingufu zo gusudira lazeri, kwinjiza urumuri rwa lazeri hejuru ya aluminiyumu hamwe nagaciro ntarengwa byo gusudira byimbitse.Nimwe mubikorwa byizewe bya aluminium alloy yo gusudira.Kugeza ubu, inzira ntabwo ikuze kandi iri mubushakashatsi nubushakashatsi.

Ingorane zo gusudira laser ziratandukanye kuri aluminiyumu itandukanye.Ubuvuzi budashyushye bwashimangiye aluminium na aluminium alloy 1000, seri 3000 hamwe na 5000 bifite weldable nziza;4000 serie alloy ifite sensibilité yo hasi cyane;Kubice 5000 byuruhererekane, iyo ω Iyo (Mg) = 2%, ibinyomoro bitanga ibice.Hamwe no kwiyongera kwa magnesium, imikorere yo gusudira iratera imbere, ariko guhindagurika no kurwanya ruswa biba bibi;Urukurikirane rwa 2000, urukurikirane rwa 6000 hamwe na 7000 yuruhererekane ruvanze rufite imyumvire myinshi yo guturika gushyushye, gushinga nabi gusudira, no kugabanuka gukabije kwubusaza bwa post weld.

Kubwibyo, kuri laser yo gusudira ya aluminiyumu, birakenewe gufata ingamba zikwiye no guhitamo neza uburyo bwo gusudira hamwe nuburyo bwo kubona ibisubizo byiza byo gusudira.Mbere yo gusudira, gutunganya ibikoresho hejuru, kugenzura ibipimo byo gusudira no guhindura imiterere yo gusudira nuburyo bwiza.

Guhitamo ibipimo byo gusudira

· Laser power 3KW.

· Umuvuduko wo gusudira Laser: 4m / min.Umuvuduko wo gusudira biterwa nubucucike bwingufu.Iyo ingufu zingana, niko kwihuta gusudira.

· Iyo isahani isunitswe (nka 0.8mm kuri plaque yo hanze yuruhande na 0,75mm kuri plaque yo hejuru yo hejuru), gusiba inteko bigenzurwa nikigo, muri rusange 0.05 ~ 0.20mm.Iyo gusudira kutageze kuri mm 0,15, imyuka ya zinc ntishobora gukurwa mu cyuho cy’uruhande, ariko ikurwa ku buso bwa weld, byoroshye kubyara inenge;Iyo ubugari bwa weld burenze mm 0,15, icyuma gishongeshejwe ntigishobora kuzuza icyuho rwose, bikavamo imbaraga zidahagije.Iyo uburebure bwa weld bumeze nkubwa plaque, imiterere yubukanishi nibyiza, kandi ubugari bwa weld buterwa na diameter yibanze;Ubujyakuzimu busudira biterwa n'ubucucike bw'ingufu, umuvuduko wo gusudira no kwibanda kuri diameter.

· Gazi ikingira ni argon, itemba ni 25L / min, naho umuvuduko wo gukora ni 0.15 ~ 0.20MPa.

· Wibande diameter 0,6 mm.

· Umwanya wibanze: iyo uburebure bwa plaque ari 1mm, icyerekezo kiri hejuru yubuso bwo hejuru, kandi umwanya wibanze uterwa nuburyo bwa cone.
