Umsebenzi wegesi yokuzivikela kunqubo ye-laser welding
(1) Igesi eyisivikelo ingavikela ilensi yekhanda le-laser ekungcolisweni komhwamuko wensimbi nasekuphalazeni kwamaconsi oketshezi.
(2) Umhwamuko wensimbi udonsa umsebe we-laser bese ujoyinisa ube yifu le-plasma. Uma kune-plasma eningi kakhulu, i-laser beam idliwa yi-plasma ngezinga elithile. Igesi evikelayo ingahlakaza amapayipi omusi wensimbi noma amafu e-plasma, inciphise umphumela wokuvikela we-laser, futhi ikhulise izinga lokusebenzisa elisebenzayo le-laser.
(3) Igesi eliyisivikelo lingavikela ichibi elincibilikisiwe. Uma ezinye izinto zishiselwé, i-oxidation yangaphezulu ingashaywa indiva. Ukuvikelwa nakho kungashaywa indiva. Kodwa-ke, ngezicelo eziningi, i-helium, i-argon, i-nitrogen namanye amagesi avame ukusetshenziselwa ukuvikela, ukuze i-workpiece ibe Gwema i-oxidation ngesikhathi sokushisela.
Cigesi evikela i-ommonly ye-laser welding
(1) I-Helium: amandla aphezulu e-ionization, i-ionization degree ephansi ngaphansi kwesenzo se-laser, ingalawula kahle ukwakheka kwefu le-plasma, futhi inomsebenzi ophansi, ngokuyisisekelo ayisabelani ngamakhemikhali ngensimbi, iyigesi evikelayo ekahle kakhulu. Nokho, izindleko ze-helium ziphezulu kakhulu futhi ngokuvamile zisetshenziselwa ucwaningo lwesayensi.
(2) Igesi ye-Argon: Amandla e-ionization aphansi ngokuqhathaniswa, futhi i-ionization degree iphezulu ngaphansi kwesenzo se-laser, esingahambisani nokulawula ukwakheka kwefu le-plasma, futhi kuzoba nomthelela othile ekusetshenzisweni ngempumelelo kwe-laser; kodwa umsebenzi wayo uphansi, okunzima ukuwuqhathanisa nokujwayelekile Insimbi ibhekana nokusabela kwamakhemikhali, futhi izindleko aziphezulu, ngakho-ke ingasetshenziswa njengegesi evamile yokuvikela. .
(3) I-nitrogen: amandla e-ionization amaphakathi, aphezulu kune-argon futhi aphansi kune-helium. I-nitrogen ingasabela ngamakhemikhali nge-aluminium alloy nensimbi ye-carbon ezingeni lokushisa elithile ukuze ikhiqize ama-nitride, okuzokwandisa ukuqina kwe-weld, kunciphise ukuqina, futhi kuzoba nomthelela omubi kakhulu kuzakhiwo zemishini zejoyinti lokushisela. Ngakho-ke, akunconywa ukusebenzisa i-nitrogen. I-aluminium alloy kanye ne-carbon steel welds ivikelekile. I-nitride ekhiqizwa ukusabela kwamakhemikhali phakathi kwe-nitrogen nensimbi engagqwali ingakhuphula amandla we-weld joint, okuzosiza ukuthuthukisa izakhiwo zemishini ze-weld. Ngakho-ke, i-nitrogen ingasetshenziswa njengegesi evikelayo lapho kushiselwa insimbi engagqwali.
Indlela yokuvikela ukungena kwegesi
Njengamanje kunezindlela ezimbili eziyinhloko zokuphefumula ngegesi evikelayo:
(1) Kuyisivikelo se-side-blow ye-shaft eseceleni
(2) Kuyisivikelo se-coaxial, njengoba kuboniswe esithombeni esingezansi.
Igesi evikelayo ephephethwa ngaphakathi ayidingi nje kuphela ukuvikela i-weld pool ngesikhathi esifanele, kodwa futhi idinga ukuvikela indawo eqinile eshiselwe. Ngakho-ke, ukuvikela okuvuthela ohlangothini lwe-side-shaft ngokuvamile kusetshenziswa, ngoba le ndlela yokuvikela ilinganiselwe Uhlu lokuvikela lwendlela yokuvikela i-coaxial lubanzi, ikakhulukazi endaweni lapho i-weld isanda kuqina khona.
Ukuvuthela eceleni kwe-sideshaft Kuzinhlelo zokusebenza zobunjiniyela, akuyona yonke imikhiqizo engavikelwa ukuvunguza kwe-sideshaft. Kweminye imikhiqizo ethile, ukuvikelwa kwe-coaxial kuphela kungasetshenziswa. Idinga ukuqondiswa kusukela esakhiweni somkhiqizo kanye nefomu elihlangene. Ukukhetha ucansi.
Ukuze umumo wokushisela uqonde, ifomu elihlanganyelwe lingaba ilunga le-butt, i-lap joint, ilunga lekhona noma ijoyinti elihlanganisiwe elihlanganisiwe. Lolu hlobo lomkhiqizo lusebenzisa indlela yokuvikela igalelo eliseceleni.
Emikhiqizweni omumo wayo wokushisela uyindilinga noma oyi-polygonal, futhi amafomu ahlangene angamalunga ezinqe, amalunga ethanga, amalunga okushisela agqagqene, njll., kungcono ukusebenzisa ukuvikelwa kwe-coaxial kulolu hlobo lomkhiqizo.
Lokhu okungenhla kuwumsebenzi kanye nendlela yokuvikela yegesi ye-laser welding shielding. Enqubweni yokusetshenziswa kwangempela, kufanele kukhethwe ngokuvumelana nesimo sangempela.
