Njengendlela eqhelekileyo yokucubungula kwishishini lokuvelisa lanamhlanje, umatshini wokusika i-laser uyaphula indlela yesiqhelo yokucubungula kwaye usetyenziswa kakhulu kumashishini ahlukeneyo anendlela entsha yokusika, ingakumbi umatshini wokusika i-fiber laser.
Abasebenzisi abawaziyo umatshini wokusika i-fiber laser kufuneka bazi ukuba kufuneka usebenzise igesi encedisayo kwinkqubo yokusika. Yiyo loo nto abantu abaninzi bexhalabele kakhulu umba "wegesi".
Namhlanje ndiza kwabelana nani ngegesi esetyenziselwa ukusika i-fiber laser.
Kutheni kufuneka songeze igesi encedisayo ngexesha lokucubungula?
Ngaphambi kokuba sifumane indlela yokukhetha igesi encedisayo, kufuneka siqale siqonde ukuba kutheni kusetyenziswa igesi encedisayo kunye nendima yegesi encedisayo. Emva kwesishwankathelo samava: Ukongeza ekuvutheleni i-slag kwindawo evulekileyo ye-coaxial, ukusetyenziswa kwegesi encedisayo kunokupholisa umphezulu wento ecutshungulwayo, kunciphise indawo echaphazeleka bubushushu, kupholise ilensi egxile kuyo, kwaye kuthintele umsi ukuba ungangeni kwisihlalo selensi ukuze ungcolise ilensi kwaye ubangele ilensi ukuba ishushu kakhulu; ukongeza, ezinye iigesi ezisikayo zinokukhusela izinto ezingundoqo. Ukukhetha uxinzelelo lwegesi kunye nohlobo kunempembelelo enkulu kwinkqubo yokusika. Uhlobo lwegesi encedisayo luya kuba nefuthe elithile ekusebenzeni kokusika, kubandakanya isantya sokusika, ubukhulu bokusika, njl.
Iigesi ezincedisayo ezinokusetyenziswa koomatshini bokusika nge-laser ziquka umoya, i-nitrogen, i-oxygen kunye ne-argon. Ngezantsi, i-Huazu Laser iza kwazisa ukusetyenziswa kunye neempawu zeegesi ezincedisayo ezahlukeneyo.
1. Umoya
Umoya ungafumaneka ngokuthe ngqo yi-air compressor, ngoko ke uxabiso liphantsi kakhulu xa uthelekiswa nezinye iigesi. Nangona umoya une-oxygen emalunga ne-20%, ukusebenza kakuhle kokusika kuncinci kakhulu kunokomoya, kwaye amandla okusika afana nalawo e-nitrogen. Ifilimu ye-trace oxide iya kuvela kumphezulu wokusika, kodwa ingasetyenziswa njengendlela yokuthintela umaleko wokugquma ukuba ungawi. Umphetho womcu utyheli.
Izinto eziphambili ezisebenzayo yi-aluminium, i-aluminium alloy, i-stainless copper, i-brass, i-electroplated steel, i-non-metal, njl. Nangona kunjalo, xa iimfuno zomgangatho wemveliso yokusika ziphezulu, i-aluminium, i-aluminium alloy, i-stainless steel, njl. azifanelekanga emoyeni kuba umoya uya kunyibilikisa izinto eziphambili.
2. I-nitrogen
Xa usika ezinye iintsimbi, ioksijini iya kwenza ifilimu ye-oxide kumphezulu wokusika. Ukusebenzisa i-nitrogen kunokuthintela ifilimu ye-oxide ukuba ingabonakali ngaphandle kwe-oxidation. Ngenxa yoko, ineempawu zokuba iyakwazi ukudityaniswa ngokuthe ngqo, ifakelwe, kwaye inokumelana nokugqwala okunamandla. Umphetho wokusika umhlophe.
Iipleyiti eziphambili ezisebenzayo yintsimbi engatyiwayo, intsimbi efakwe ngombane, ubhedu, i-aluminium, i-aluminium alloy, njl.
3. Ioksijini
Isetyenziswa kakhulu ekusikeni nge-laser yentsimbi yekhabhoni. Ngelixa kusetyenziswa ubushushu bempendulo ye-oksijini ukuphucula kakhulu ukusebenza kakuhle kokusika, ifilimu ye-oxide evelisiweyo iya kwandisa i-beam spectrum absorption factor yezinto ezibonisa ukukhanya. Ubuso bomphetho osikiweyo bumnyama okanye bumthubi omnyama.
Isebenza kakhulu kwintsimbi eqengqiweyo, intsimbi eqengqiweyo yesakhiwo se-welding, intsimbi yekhabhoni yesakhiwo soomatshini, ipleyiti yoxinzelelo oluphezulu, ipleyiti yesixhobo, intsimbi engatyiwayo, intsimbi efakwe ngombane, ubhedu, i-alloy yobhedu, njl.
4. I-Argon
I-Argon yigesi engasebenziyo. Isetyenziselwa ukuthintela i-oxidation kunye ne-nitridation ekusikeni koomatshini bokusika nge-laser. Ikwasetyenziswa ekudibaniseni. Xa ithelekiswa nezinye iigesi zokucubungula, ibiza kakhulu kwaye inyusa iindleko ngokufanelekileyo. Isiphelo esisikiweyo simhlophe.
Izinto eziphambili ezisebenzayo yi-titanium, i-titanium alloy, njl.
Kwimixholo engentla, iigesi ezininzi zingasetyenziswa kwihlabathi liphela. Eyona nto ibalulekileyo kukuqwalasela iindleko zokusika kunye neemfuno zemveliso. Umzekelo, xa usika izinto zentsimbi engagqwaliyo, xa umgangatho okanye umgangatho womphezulu wemveliso ungekho phezulu kakhulu, njengokuba imveliso yokusika kufuneka idlule ekupeyinteni nakwezinye iinkqubo zokucubungula, umoya ungasetyenziswa njengegesi yokusika, enokunciphisa iindleko ezininzi. Xa imveliso yokusika iyimveliso yokugqibela kwaye kungekho nkqubo ilandelayo, kuyimfuneko ukusebenzisa igesi ekhuselayo, njengeemveliso zenkqubo. Ke ngoko, kwinkqubo yokusika nokuvala, kuyimfuneko ukukhetha igesi ngokweempawu zemveliso.
