Ukukhethwa Okufanele Kwegesi Yokuvikela — Isihluthulelo Sokuthuthukisa Ikhwalithi Yokushisela Nokwandisa Isikhathi Sesevisi Yemishini

Ekushiseni nge-laser, ukukhethwa okufanele kwegesi yokuvikela kungenye yezinto ezibalulekile ezinquma ikhwalithi yokushisisa. Igesi yokuvikela ayithuthukisi nje kuphela ukushelela kobuso bokushisisa futhi inciphise ukungcoliswa okubangelwa ukuthintana.

phakathi kwechibi elincibilikisiwe nomoya ozungezile, kodwa futhi kunciphisa kakhulu ukungcoliswa kwelensi, kuvikela indlela yangaphakathi yokukhanya yomshini wokushisela, futhi kwandise impilo yesevisi yemishini.Umshini wokushisela we-laser ophathwayo

imiphumela ihlobene kakhulu nokukhethwa kwegesi—lesi sinyathelo esibalulekile akufanele sishaywe indiva.

Imisebenzi yegesi yokuvikela

Ukuvimbela Kokuqala Kokungcoliswa Nokubola:Ihlukanisa ichibi elincibilikisiwe futhi ishise emoyeni endaweni yokushiselela enokushisa okuphezulu, ivimbela ukushiswa kanye nokumuncwa kokungcola.

Ukuthuthukiswa Kwesibili Kokwakheka Kwe-Weld:Kunciphisa ukuchitheka futhi kuthuthukisa ukushelela kwe-weld, ukufana, kanye nokubukeka.

Ukuvikelwa Komkhathi Ongagqwali: Ngokudala indawo engagqwali ezungeze indawo yokushisela, ukuvikela igesi kudlala indima ebalulekile ku:

Ukuvimba Kwesithathu Ukuphazamiseka Komoya:Ivimbela ngempumelelo umoya-mpilo, i-nitrogen, kanye nomswakama emoyeni ukuthi ungahlangani nedamu elincibilikisiwe elinokushisa okuphezulu, igwema ukuvuleka, ukufakwa kwe-oxidation, nokunye.

amaphutha.

Izingxenye Zemishini Yokuvikela Yesine:Kunciphisa ukungcoliswa kwama-spratter kulensi yesibhamu sokushisela, kunciphisa ingozi yokuwohloka kwendlela yokukhanya okubangelwa ukubola noma ukugqwala, futhi kwandise izikhawu zokulungisa.

Izincomo Ezivamile Zegesi Yokuvikela

I-Argon

Njengegesi engasebenzi esetshenziswa kakhulu ekushiseleni, i-argon inikeza ukuzinza kwamakhemikhali okuhle kakhulu kanye nekhono lokusekela i-arc. Ubuningi bayo obuphezulu buyivumela ukuthi yakhe ungqimba oluqinile lokumboza phezu kwechibi elincibilikisiwe, okukhiqiza ubuhle

okujabulisayo i-laser imishini yokushisela. Ifaneleka kakhulu ekushiseleni izinsimbi ezivame ukushiswa njengensimbi engagqwali, ama-aluminium alloys, kanye nama-titanium alloys.

I-nitrogen

Ezintweni ezifana nensimbi ethambile kanye nensimbi engena-alloy ephansi, i-nitrogen iyindlela engabizi kakhulu, enikeza ukungasebenzi kahle okumaphakathi kanye nezinzuzo zezomnotho. Kwezinye izinsimbi, ingathuthukisa ubulukhuni bomphezulu, kodwa emazingeni okushisa aphezulu, ingase

sabela ngensimbi eyisisekelo. Ukufaneleka kufanele kuhlolwe ngokusekelwe ezidingweni ezithile zenqubo.

I-Helium

I-Helium ihamba phambili ekusetshenzisweni kokushisela okunamandla aphezulu, njengokushisela ithusi kanye ne-alloys yethusi. Ukushisa kwayo okuphezulu kwenza kube lula ukungena ngokujulile, kunqobe inselele ebangelwa ukushisa okuphezulu kwethusi.

ukushabalaliswa, kuyilapho kunciphisa nokushintsha kombala we-weld oxidation. Ngenxa yezindleko zayo eziphakeme, i-helium ngokuvamile igcinelwe izinhlelo zokusebenza ezithile, ezifunwa kakhulu.

Ubumsulwa kanye Nezinyathelo Zokuqapha

Ukuhlanzeka Kwegesi: Sebenzisa amagesi ahlanzekile kakhulu (≥ 99.99%) ukuqinisekisa ukusebenza kahle kokushisela kanye nekhwalithi ephezulu yokushisela. Ngisho nokungcola okuncane kungabangela amaphutha amakhulu njengokubhoboka nokuqhekeka.

Amagesi Avinjelwe: Amagesi axubile, i-carbon dioxide, kanye nomoya-mpilo kufanele kugwenywe ngokuqinile, njengoba kungaholela ekushiseni kwe-weld, ukwanda kwama-porosity, ngisho nomonakalo ohlelweni lwe-optical.

Isiphetho:

Ukukhetha nokusebenzisa igesi yokuvikela efanele akugcini nje ngokuthuthukisaUmshini wokushisela we-laser ongu-4 ku-1ukubukeka kanye namandla kodwa futhi kunciphisa izindleko zokulungisa futhi kwandise isikhathi sokuphila kwemishini. Kuyisici esibalulekile ekuqinisekiseni ukuthi

imisebenzi yokuwelda nge-laser esebenza kahle kakhulu futhi ezinzile.
