Ungayikhetha kanjani igesi yomshini wokusika i-fiber laser?

Njengendlela evamile yokucubungula embonini yokukhiqiza yanamuhla, umshini wokusika nge-laser uphula indlela yokucubungula yendabuko futhi usetshenziswa kabanzi ezimbonini ezahlukahlukene ngendlela entsha yokusika, ikakhulukazi umshini wokusika nge-laser ye-fiber

Abasebenzisi abaziyo umshini wokusika i-fiber laser kufanele bazi ukuthi kumele usebenzise igesi elisizayo enqubweni yokusika. Yingakho abantu abaningi bekhathazeka kakhulu ngendaba "yegesi".

Namuhla ngizokwabelana nawe ngegesi esetshenziselwa ukusika i-fiber laser.

Kungani sidinga ukwengeza igesi elisizayo ngesikhathi sokucubungula?

Ngaphambi kokuthola ukuthi ungayikhetha kanjani igesi eyisizayo, kumele siqale siqonde ukuthi kungani kusetshenziswa igesi eyisizayo kanye nendima yegesi eyisizayo. Ngemva kwesifinyezo sesipiliyoni: Ngaphezu kokususa i-slag emngxunyeni we-coaxial, ukusetshenziswa kwegesi eyisizayo kungapholisa ubuso bento ecutshunguliwe, kunciphise indawo ethintekile ekushiseni, kupholise ilensi yokugxila, futhi kuvimbele umusi ukuthi ungangeni esihlalweni selensi ukuze kungcoliswe ilensi futhi kubangele ilensi ukuthi ishise ngokweqile; ngaphezu kwalokho, amanye amagesi okusika angavikela nezinto eziyinhloko. Ukukhetha umfutho wegesi kanye nohlobo kunethonya elikhulu enqubweni yokusika. Uhlobo lwegesi eyisizayo luzoba nomthelela othile ekusebenzeni kokusika, kufaka phakathi isivinini sokusika, ukujiya kokusika, njll.

Amagesi asizayo angasetshenziswa emishinini yokusika nge-laser afaka phakathi umoya, i-nitrogen, i-oxygen kanye ne-argon. Ngezansi, i-Huazu Laser izokwethula ukusetshenziswa kanye nezici zamagesi asizayo ahlukene.
1. Umoya
Umoya unganikezwa ngqo yi-air compressor, ngakho-ke ushibhile kakhulu uma uqhathaniswa namanye amagesi. Nakuba umoya uqukethe cishe i-oxygen engu-20%, ukusebenza kahle kokusika kuncane kakhulu kunomoya-mpilo, futhi amandla okusika afana nawe-nitrogen. Ifilimu ye-trace oxide izovela ebusweni bokusika, kodwa ingasetshenziswa njengesilinganiso sokuvimbela ungqimba lokumboza ukuthi lungawi. Ubuso bokugcina bokusika buphuzi.
Izinto eziyinhloko ezisebenzayo yi-aluminium, i-aluminium alloy, ithusi elingagqwali, ithusi, ipuleti lensimbi elifakwe ngogesi, okungeyona insimbi, njll. Kodwa-ke, lapho izidingo zekhwalithi zomkhiqizo wokusika ziphezulu, i-aluminium, i-aluminium alloy, insimbi engagqwali, njll. azifanelekeli umoya ngoba umoya uzokhipha i-oxidize ezintweni eziyinhloko.

2. I-nitrogen
Uma usika ezinye izinsimbi, umoya-mpilo uzokwakha ifilimu ye-oxide ebusweni bokusika. Ukusebenzisa i-nitrogen kungavimbela ifilimu ye-oxide ukuthi ingabonakali ngaphandle kwe-oxidation. Ngenxa yalokho, inezici zokukwazi ukushintshwa ngqo, ukufakwa, kanye nokumelana nokugqwala okunamandla. Ubuso bokugcina bokusika bumhlophe.
Amapuleti asebenzayo ayinhloko yinsimbi engagqwali, insimbi efakwe ngogesi, ithusi, i-aluminium, i-aluminium alloy, njll.

3. I-oksijini
Isetshenziswa kakhulu ekusikeni nge-laser kwensimbi yekhabhoni. Ngenkathi kusetshenziswa ukushisa kokusabela komoya-mpilo ukuthuthukisa kakhulu ukusebenza kahle kokusika, ifilimu ye-oxide ekhiqizwayo izokwandisa isici sokumuncwa kwe-beam spectrum yezinto ezibonisa ukukhanya. Ubuso bokunqunywa bumnyama noma buphuzi obumnyama.
Isebenza kakhulu ensimbini egoqiwe, insimbi egoqiwe yesakhiwo sokushisela, insimbi yekhabhoni yesakhiwo somshini, ipuleti lokucindezela okuphezulu, ipuleti lamathuluzi, insimbi engagqwali, insimbi eboshwe ngogesi, ithusi, i-alloy yethusi, njll.

4. I-Argon
I-Argon iyigesi engasebenzi kahle. Isetshenziselwa ukuvimbela i-oxidation kanye ne-nitridation ekusikeni komshini wokusika nge-laser. Iphinde isetshenziswe ekushiseni. Uma iqhathaniswa namanye amagesi okucubungula, iyabiza futhi inyusa izindleko ngokufanele. Ubuso bokunqunywa bumhlophe.
Izinto eziyinhloko ezisebenzayo yi-titanium, i-titanium alloy, njll.

Kokuqukethwe okungenhla, amagesi amaningi angasetshenziswa emhlabeni wonke. Isihluthulelo ukucabangela izindleko zokusika kanye nezidingo zomkhiqizo. Isibonelo, lapho usika izinto zensimbi engagqwali, lapho ikhwalithi noma ikhwalithi yomkhiqizo ingekho phezulu kakhulu, njengokuthi umkhiqizo wokusika udinga ukupenda nezinye izinqubo zokucubungula, umoya ungasetshenziswa njengegesi yokusika, okunganciphisa izindleko eziningi. Uma umkhiqizo wokusika uwumkhiqizo wokugcina futhi kungekho nqubo elandelayo, kuyadingeka ukusebenzisa igesi evikelayo, njengemikhiqizo yokucubungula. Ngakho-ke, enkambisweni yokusika nokuvala, kuyadingeka ukukhetha igesi ngokwezici zomkhiqizo.
