Igesi engabonakali futhi engaphatheki ', engeke inganakwa e-laser welding, ibhekisela kugesi yokuvikela. Ukukhetha kwayo kuthinta ngqo ikhwalithi, ukusebenza kahle kanye nezindleko zokukhiqizwa kwe-welding. Namuhla, I-Hanao Tech izokhuluma nawe mayelana nokuvikela ulwazi oluhlobene negesi.
1. Iqhaza lesimo sokuvikela
E-laser welding, igesi evikelekile izothinta ukwakheka kwe-weld, ikhwalithi yesendlalelo, ububanzi bokungena kanye nokungena. Ezimweni eziningi, ukushaya igesi evuthayo kuzoba nomthelela omuhle ku-weld, kodwa kungahle futhi kube nomphumela omubi.
Imiphumela Emihle
1) Ukuhlukaniswa okuyilo kwegesi okuvikayo kuzovikela i-Weld Pool ngempumelelo ukuze unciphise noma ugweme ngisho nokugwema i-oxidation;
2) Ukushaywa okuyilo kwegesi evikelekile kunganciphisa ngempumelelo i-spatter eyenziwe ngesikhathi senqubo ye-welding;
3) Ukuhlukaniswa okulungile kwegesi evikelayo kungakhuthaza ukusakazeka komfaniswano wechibi leWeld lapho kuqinisa, kwenza ukwakheka kwe-weld kufana futhi kube kuhle;
4) Ukushaywa okulungile kwegesi evikelayo kunganciphisa ngempumelelo umphumela wokuvikela we-pelula yensimbi ye-vapor noma ifu le-plasma ku-laser, bese ukhuphula izinga lokusebenzisa le-laser;
5) Ukushaywa okulungile kwegesi evikelekile kunganciphisa ngempumelelo i-welld poor.
Uma nje uhlobo lwegesi, izinga lokugeleza kwegesi, kanye nendlela yokuhluleka kukhethwe kahle, umphumela ofanele ongatholakala. Kodwa-ke, ukusetshenziswa okungalungile kwegesi evikelekile nakho kungaba nemiphumela emibi ekushiseni.
Imiphumela Emibi
1) Ukuhlukaniswa okungafanele kokuvikelwa kwegesi okuvikayo kungahle kube nomthelela omubi we-weld;
2) Ukukhetha uhlobo olungalungile lwegesi kungadala ukuqhekeka eWeld, futhi kungahle kuholele ekunciphiseni kwezindawo zemishini ye-Weld;
3) Ukukhetha ukugeleza kwegesi okungalungile kungahle kuholele ku-weld oxidation enkulu (ngabe ngabe izinga lokugeleza likhulu kakhulu noma lincane kakhulu), futhi lingabangela futhi i-welld pool metal iphazanyiswe kanzima ngamabutho angaphandle, okuholela ekuweni kwe-weld noma ekusebenzeni okungalingani;
4) Ukukhetha indlela embi yokujova igesi kuzoholela e-Weld kungafinyeleli emphumeleni wokuvikela noma ngokuyisisekelo akukho mphumela wokuvikela noma othinta ukwakheka kabi kwe-wald;
I-5) Ukuhlukaniswa kwegesi okuvikelayo kuzoba nomthelela othile ekufuneni kwe-weld, ikakhulukazi lapho amapuleti amancanyana e-welding, kuzonciphisa ukungena kwe-weld.
2. Izinhlobo zegesi evikelayo
Amagesi asetshenziswa ngokuvikelwa asetshenziswa kakhulu we-laser wellding ikakhulukazi afaka i-nitrogen, i-argon, kanye ne-helium, futhi izakhiwo zazo zomzimba nezomakhemikhali zihlukile, ngakho-ke umphumela we-weld uhlukile.
1) nitrogen
Ama-Ionization Energy of Nitrogen alinganiselwe, aphakeme kunaleyo ye-argon, ephansi kunaleyo ye-helium, kanti izinga le-ionization ngaphansi kwe-laser lisezingeni le-i-laser, ngaleyo ndlela anciphise ukwakheka kwezinga lokusetshenziswa kwe-laser. I-nitrogen ingasabela ngamakhemikhali nge-aluminium alloy nensimbi ye-carbon endaweni yokushisa ethile ukukhiqiza ama-nitrides, ancishiswe amandla amaningi we-aluminium alloy kanye nama-welds wensimbi e-carbon ukuze avikelwe.
I-nitrogen ekhiqizwa ukusabela kwamakhemikhali phakathi kwe-nitrogen kanye nensimbi engenacala kungakhulisa amandla we-weld Joint, okuzosiza ukuthuthukisa izakhiwo zemishini, ngakho-ke i-nitrogen ingasetshenziswa njengensimbi evikelekile lapho insimbi evikelekile.
2) I-Arobon
Ama-ionization amandla e-argen aphansi kakhulu, futhi i-ionization degree iphakeme ngaphansi kwesenzo se-laser, esingalungile ukulawula ukwakheka kwamafu we-plasma futhi izoba nomthelela othile ekusetshenzisweni okusebenzayo kwe-laser. Kodwa-ke, i-Argon inomsebenzi ophansi kakhulu futhi kunzima ukuhlanganisa nezinsimbi ezivamile. Ukusabela kwamakhemikhali kwenzeka, futhi izindleko ze-argon aziphakeme. Ngaphezu kwalokho, ubukhulu be-argon buphakeme, obuvumelana nokucwila esiqongweni sechibi le-weld, okungavikela kangcono ichibi le-weld, ngakho-ke lingasetshenziswa njengokusetshenziswa kwegesi okuvamile.
3) Helium
Ama-Ionization Energy of Helium aphezulu kakhulu, futhi iziqu ze-Ionization ziphansi kakhulu ngaphansi kwesenzo se-laser, esingalawula kahle ukwakheka kwefu le-plasma. I-laser ingasebenza ngezinsimbi kahle, futhi umsebenzi we-helium uphansi kakhulu, futhi empeleni akasabeli ngamakhemikhali ngezinsimbi. , ingu-welding enhle kakhulu we-selding seam igesi, kepha izindleko ze-helium ziphezulu kakhulu, futhi ngokuvamile imikhiqizo ekhiqizwe ngobukhulu ayisebenzisi le gesi. I-Helium ngokuvamile isetshenziselwa ucwaningo lwesayensi noma imikhiqizo enenani eliphakeme kakhulu lengezwe.
Uma unemibuzo noma izidingo mayelana I-Laser Welding Pipe Yenza umugqa womshini wokukhiqiza i-tube , sicela ukhululeke ukuxhumana nathi ngokuxhumana.
