Ngabe uke wahlangabezana nanoma yiziphi izici ezishisayo ezinjenge-splashes ezinkulu ngesikhathi se-welding, ukwakheka okungathandeki kwe-weld, nenani elikhulu lama-pores ngemuva kokufudumala? Lapho usacubungula ukuthi ngabe kungenxa yenkinga yezilungiselelo ze-laser welding prameter amapharamitha, uyazi ukuthi ukusetshenziswa okulungile kwegesi ye-welding wavid kubuye kube yinto ebalulekile ethinta ukwakheka nokusebenza kwe-weld. Ukukhetha igesi engcono kakhulu yokuvikela i-welding empeleni kuthuthukisa ikhwalithi ye-welding kanye nendlela ephumelelayo.
Kusukela igesi yokuvikela i-welding ibaluleke kakhulu, ke: Iyini indima yegesi evikelekile? Ungayikhetha kanjani uhlobo lwegesi evikelekile? Kufanele ashaye kanjani igesi yokuvikela phakathi kokufudumala? Okulandelayo, i-hangao tech (seko mishini) kuzoholela wonke umuntu ukuthi afunde kabanzi.
Indima yegesi evikelayo
E-laser welding, igesi evikelayo izothinta ukwakheka kwe-weld, ikhwalithi yesendlalelo, ukujula kokungena kanye nokungena kokungena kanye nobubanzi bokungena. Ezimweni eziningi, ukushaya igesi evikelekile kuzoba nomthelela omuhle ku-weld, kepha kungadala nomonakalo. Woza umphumela ongemuhle.
Imiphumela Emihle
1) Ukushaywa okuyilo kwegesi okuvikayo kuzovikela i-Weld Pool ngempumelelo ukunciphisa noma ukugwema i-oxidation;
2) Ukushaywa okuyilo kwegesi evikelekile kunganciphisa ngempumelelo i-spatter eyenziwe ngesikhathi senqubo ye-welding;
3) Ukushaywa okuyilo kwegesi evikelekile kungakhuthaza ukusakazeka komfaniswano we-weld pool ngesikhathi sokuqina, ukuze iwelde yakhiwa ngokufana futhi kahle;
4) Ukushaywa okuyilo kwegesi evikelekile kunganciphisa ngempumelelo umphumela wokuvikela wensimbi yensimbi ye-vapor noma ifu le-plasma e-laser, bese ukhuphula izinga lokusetshenziswa elisebenzayo le-laser;
5) Ukushaywa okuyilo kwegesi evikelekile kunganciphisa ngempumelelo i-welding seam porisity.
Uma nje uhlobo lwegesi, izinga lokugeleza kwegesi, kanye nendlela yokushaya kukhethwe kahle, umphumela oyifunayo ungatholakala.
Kodwa-ke, ukusetshenziswa okungalungile kwegesi evikelekile nakho kuzoba nomphumela omubi ku-welding
1) Ukushaywa okungalungile kwegesi evikelekile kungadala ukonakala kwe-weld:
① Khetha ukukhetha uhlobo lwegesi olungalungile kungadala ukuqhekeka eWeld, futhi kungadala futhi izindawo ze-weld zokwehla;
②Khetha Ukuqunjelwa kwegesi engalungile yokugeleza kwegesi kungadala i-axidation engathi sína ye-weld (noma ngabe ukugeleza kukhulu kakhulu noma kube mncane kakhulu), futhi kungahle kube yinsimbi ye-weld pool ukuthi iphazanyiswe kabi ngamabutho angaphandle futhi ibangele ukuthi iWeld iwenze noma ivele ngokungafanele;
Ukuqamba izindlela ezingalungile zegesi kuzodala ukuthi umthungo we-welding wehluleka ukufeza umphumela wokuvikelwa noma ngokuyisisekelo akukho mphumela wokuvikelwa noma unomthelela ongemuhle ekwakhekeni komthungo we-welding;
2) Ukushaya kugesi okuvikayo kuzoba nomthelela othile ekungeneni kwe-weld, ikakhulukazi lapho amapuleti amancanyana e-wellding, kuzonciphisa ukungena kwe-weld.
Izinhlobo zegesi evikelayo
Amagesi ajwayelekile asetshenziswa ngokuvikelwa kwe-laser wellding ikakhulukazi afaka i-N2, AR, yena, kanye nezakhiwo zabo zenyama nangamakhemikhali zihlukile, ngakho-ke imiphumela yabo ihlukile.
Nitrogen n2
Intengo ingekho eshibhile, kepha ayilungele ukufudumala ezinye zensimbi engenacala. Ama-Ionization Energy of N2 alinganiselwe, aphakeme kunaleyo ye-AR futhi ephansi kunaleyo. Ngaphansi kwesenzo se-laser, i-Ionization degree imaphakathi, okunganciphisa ukwakheka kwefu le-plasma futhi kwandise izinga lokusetshenziswa kwe-laser. I-nitrogen ingasabela ngamakhemikhali nge-aluminium alloy ne-carbon steel emazingeni okushisa athile ukukhiqiza ama-nitrides, azokhulisa ubuqili be-weld, anciphise ubunzima bemishini ehlanganisiwe. Ngakho-ke, akunconywa ukusebenzisa i-nitrogen. I-Aluminium Alloy ne-weld yensimbi ye-carbon iyavikelwa.
I-nitride ekhiqizwa ukusabela kwamakhemikhali phakathi kwe-nitrogen nensimbi engagqwali ingakhulisa amandla we-weld Joint, okuzosiza ukuthuthukisa izakhiwo zemishini ze-weld. Ngakho-ke, i-nitrogen ingasetshenziswa njengegesi evikelekile lapho insimbi engagqwali.
I-Argon AR
Intengo ishibhile, ubukhulu buphakeme, futhi umphumela wokuvikelwa ungcono. Ingaphezulu le-weldentiment libushelelezi kunamagesi we-helium, kepha litholwa ku-plasma yensimbi yokushisa ephezulu yensimbi. Kuvinjelwe ngokujulile. Ama-ionization amandla we-AR aphansi, futhi iziqu ze-Ionization ziphakeme ngaphansi kwesenzo se-laser, esingalungile ukulawula ukwakheka kwefu le-plasma, futhi kuzoba nomthelela othile ekusetshenzisweni okusebenzayo kwe-laser. Kodwa-ke, umsebenzi we-AR uphansi kakhulu futhi kunzima ukuxhumanisa ngamakhemikhali ngezinsimbi ezijwayelekile. Izindleko ze-AR aziphakeme. Ngaphezu kwalokho, ubukhulu be-AR buphakeme, okuzuzisa ukucwila esiqongweni sechibi le-weld, futhi kungavikela kangcono ichibi le-weld, ngakho-ke lingasetshenziswa njengegesi evamile yokuvikela.
Helium he
Intengo iyabiza kakhulu, kepha umphumela uhamba phambili, ukuze i-laser idlule ngqo futhi ifinyelele ebusweni bomsebenzi ngaphandle kokuvinjwa. Ama-Ionization amandla ka-Uphakeme kakhulu, futhi iziqu ze-Ionization ziphansi kakhulu ngaphansi kwesenzo se-laser, esingalawula kahle ukwakheka kwefu le-plasma. I-laser ingasebenza ngensimbi kahle, futhi umsebenzi wawo uphansi kakhulu, futhi empeleni akasabeli ngamakhemikhali ngensimbi. Kuyigesi enhle yokuvikela imishini yokufudumala, kepha izindleko ze-he liphezulu kakhulu. Ngokuvamile, imikhiqizo yokukhiqiza eningi ngeke isebenzise le gesi. Ngokuvamile usetshenziselwa ucwaningo lwesayensi noma imikhiqizo enenani eliphakeme kakhulu lengezwe.
I-Hanao Tech (Seko Imishini) ineminyaka engaphezu kwengu-20 yesipiliyoni ku I-Stainless Insimbi Yezimboni I-Pibane Production Line Tube wenza imishini ekhiqiza imboni. Ochwepheshe beqembu le-R & D abavuthiwe kanye nochwepheshe bomhlangano bazoqhuba uhla oluphelele lokudideka nokuphindaphindwayo emgqeni ngamunye wokukhiqiza ngaphambi kokuthunyelwa, ukuze kwandiswe imishini. Khawulela ukusebenza kahle futhi unciphise ubunzima bokufakwa kamuva kanye nokwenza iphutha kumakhasimende.
