Mashandisiro eGasi nemazvo muLaser Welding

Mune laser welding, gasi rinodzivirira richakanganisa weld kuumba, weld mhando, weld kudzika uye weld hupamhi. Muzviitiko zvakawanda, kuvhuvhuta gasi rinodzivirira kuchava nemhedzisiro yakanaka pane weld, asi zvinogona kuunza mhedzisiro yakaipa.

1. Kuvhuvhuta kwakaringana mugasi rinodzivirira kuchadzivirira zvinobudirira dziva re weld kuderedza kana kutodzivirira oxidation;

2. Kuvhuvhuta kwakaringana mugasi rekudzivirira kunogona kunyatso kudzikisa kupfachuka kunogadzirwa mukugadzira welding;

3. Kufuridzira kwakaringana mugasi rinodzivirira kunogona kuita kuti weld pool solidification yaenzane kupararira, ita kuti weld iite yunifomu uye yakanaka;

4. Kuvhuvhuta kwakakodzera kwegasi rinodzivirira kunogona kudzikisa zvinobudirira kudzivirira kwesimbi mhute kana gore replasma palaser, uye kuwedzera chiyero chekushandisa chinoshanda chelaser;

5. Kuvhuvhuta kwakakodzera kwegasi rinodzivirira kunogona kuderedza zvinobudirira porosity ye weld.

Chero bedzi rudzi rwegasi, kuyerera kwegesi uye kuvhuvhuta modhi zvakasarudzwa nenzira kwayo, iyo yakanakira mhedzisiro inogona kuwanikwa.

Nekudaro, kushandiswa zvisina kunaka kwegasi rekudzivirira kunogona kukanganisawo welding.

Migumisiro yakaipa

1. Kufuridza zvisirizvo kwegasi rinodzivirira kunogona kutungamira kune weld isina kunaka:

2. Kusarudza rudzi rusina kunaka rwegasi kunogona kutungamira mukutsemuka kweweld uye kuderedza ma mechanical properties ye weld;

3. Kusarudza gasi risiri iro rinovhuvhuta kuyerera mwero kunogona kutungamirira kune yakakomba weld oxidation (ingave iyo yekuyerera yakakura kana yakanyanya kudiki), uye inogonawo kuita kuti weld pool simbi ivhiringidzike zvakanyanya nekunze kwesimba, zvichikonzera kudonha kwe weld kana kuumbwa kusina kuenzana;

4. Kusarudza nzira isiriyo yekuvhuvhuta gasi kuchaita kuti kukundikana kwekudzivirira kweiyo weld kana kunyangwe kusava nemhedzisiro yekudzivirira kana kuve nemhedzisiro yakaipa pakuumba weld;

5. Kuvhuvhuta mugasi rinodzivirira kuchava nekukanganisa kudzika kwe weld, kunyanya kana ndiro yakaonda yakasungirirwa, inoderedza kudzika kwe weld.

Mhando yekudzivirira gasi

Iwo anowanzo shandiswa laser welding ekudzivirira magasi anonyanya kuve N2, Ar, Iye, ane chimiro chemuviri uye chemakemikari zvinhu zvakasiyana, saka mhedzisiro pane weld zvakare yakasiyana.

1. N2

Iyo ionization simba reN2 ine mwero, yakakwirira kupfuura iyo yeAri uye yakaderera pane iyo yaIye. Iyo ionization degree yeN2 yakajairika pasi pechiito chelaser, iyo inogona kudzikisa zvirinani kuumbwa kweplasma gore uye nekudaro kuwedzera inoshanda chiyero chekushandiswa kwelaser.Nitrogen inogona kuita nealuminium alloy uye kabhoni simbi pane imwe tembiricha, ichigadzira nitride, iyo inovandudza brittleness ye weld, uye kuderedza kuomarara, izvo zvichava neyakakura hunyanzvi hwekushandisa, saka mhedzisiro ye nitrogen inokurudzirwa kuchengetedza aluminium alloy uye carbon steel welds.

Iyo nitrogen inogadzirwa nemakemikari reaction ye nitrogen uye simbi isina tsvina inogona kuvandudza kusimba kweiyo weld joint, iyo ichave yakanakira kuvandudzwa kweiyo mechanical properties ye weld, saka nitrogen inogona kushandiswa segasi rinodzivirira pakushongedza simbi isina tsvina.

2. Ar

Ar ionization simba rine hukama kune hushoma, pasi pesimba re laser ionization degree rakakwira, harina simba rekudzora kuumbwa kwe plasma gore, rinogona kunyatso shandisa laser kuburitsa imwe mhedzisiro, asi chiitiko cheAr chakanyanya kuderera, zvakaoma kuita nesimbi dzakajairwa, uye mutengo weAr hauna kukwirira, kuwedzera, density yeAr yakakura, inobatsira kudzivirira kunyura pamusoro pemvura. dziva, saka inogona kushandiswa seyakajairwa inodzivirira gasi.

3. Iye

Ane simba repamusoro reionization, pasi pesimba re laser ionization dhigirii rakaderera, rinogona kudzora kuumbwa kwegore replasma, laser inogona kushanda zvakanaka musimbi, WeChat nhamba yeruzhinji: micro welder, chiitiko uye Iye akaderera kwazvo, basic haaite nesimbi, yakanaka welding inodzivirira gasi, asi Iyo inodhura zvakanyanya, Iyo gasi haishandiswe kune yakakwira-kukosha zvigadzirwa, tsvagiridzo haishandiswe kune yakakwira-kukosha zvigadzirwa.
