Revolution of Welding Technology |I-Laser Welding ye-Aluminium Alloy
Ama-alloys e-aluminium asetshenziswa kakhulu emikhiqizweni ehlukahlukene yesakhiwo eshiselwe ngenxa yesisindo sawo esilula, amandla aphezulu, ukumelana nokugqwala okuhle, izakhiwo ezingezona uzibuthe, ukubunjwa okuhle nokusebenza okuhle kwezinga lokushisa eliphansi.Lapho kushiselwa ngama-alloys e-aluminium, isisindo somkhiqizo wesakhiwo esishiselwe singancishiswa ngo-50% uma siqhathaniswa nalawo ashiselwe kumapuleti ensimbi.Njengamanje, lokhu sekusetshenziswe kabanzi ezimbonini ezahlukahlukene ezifana nezindiza, i-aerospace, imoto, ibhethri lamandla, ukukhiqizwa kwemishini, ukwakhiwa kwemikhumbi, iminyango namafasitela, imboni yamakhemikhali kanye nezidingo zansuku zonke.
Ubuchwepheshe be-laser welding obuthuthukisiwe be-aluminium alloy
Ubuchwepheshe bokushisela nge-laser be-aluminium alloy ubuchwepheshe obusha obuthuthukiswe kule minyaka eyishumi edlule.Ifaka ukusebenza okuqinile, ukwethembeka okuphezulu nokusebenza kahle okuphezulu uma kuqhathaniswa nendlela yendabuko yokushisela.Nazi izinzuzo ze-laser welded aluminium alloys:
▪ Ukuminyana kwamandla aphezulu, okokufaka ukushisa okuphansi, ukuguquka kokushisa okuphansi, indawo encibilikayo encane nendawo ethinteke ekushiseni kanye nokujula okukhulu kokuncibilika.
▪ Isakhiwo sokushisela i-Microfine ngenxa yezinga eliphezulu lokupholisa kanye nokusebenza kahle kwamalunga.
▪ Ukushisela nge-laser ngaphandle kwama-electrode, kunciphisa amahora nezindleko zabantu.
▪ Ukuma kwe-workpiece eshiselwe akuthintwa uzibuthe kagesi futhi ayikhiqizi ama-X ray.
▪ Ikhono lokushisela izinto zensimbi ngaphakathi kwezinto ezivaliwe ezibonisa ngale.
▪ I-laser ingadluliselwa ezindaweni ezikude ngemicu yokubona, eyenza inqubo ivumelane nezimo.Ngamakhompyutha namarobhothi, inqubo yokushisela ingenziwa ngokuzenzakalelayo futhi ilawulwe ngokunembile.
Izinzuzo zokubhekana nama-alloys e-aluminium afakwe ukushisa
Khulisa isivinini sokucubungula
Khulisa ukusebenza kahle kokukhiqiza futhi uthuthukise ikhwalithi yokushisela ngokunciphisa kakhulu okokufaka ukushisa.
Lapho ukushisela ama-alloys e-aluminium anokuqina okuphezulu nokuqina okukhulu, kungafinyelela kalula ukushisela ngephasi elilodwa ngokwakha ukujula okukhulu kwembobo kakhiye lapho ukushisela kwe-laser deep fusion kanye nomphumela we-keyhole kwenzeka, lokho kunamandla kunezindlela zokushisela zendabuko.
Ukuqhathaniswa komthombo we-laser ojwayelekile ku-laser welding ye-aluminium alloys
Namuhla, imithombo ye-laser eyinhloko esetshenziswa emakethe i-CO2 laser, i-YAG laser ne-fiber laser.Ngenxa yokusebenza kwayo kwamandla aphezulu, i-CO2 laser ifaneleka kakhulu ekushiselelweni kwepuleti eliwugqinsi, kodwa izinga lokumuncwa kwe-CO2 laser beam ebusweni be-aluminium alloy lincane uma kuqhathaniswa, elidala ukulahleka kwamandla amaningi ngesikhathi senqubo yokushisela.
I-laser ye-YAG ngokuvamile incane ngamandla, izinga lokumuncwa kwe-YAG laser beam ebusweni be-aluminium alloy likhulu uma kuqhathaniswa nalelo le-CO2 laser, i-optical fibre conduction etholakalayo, ukuguquguquka okuqinile, ukuhlelwa kwenqubo elula, njll., ububi be-YAG: i amandla okukhipha kanye namandla okuguqula i-photoelectric aphansi.
I-fiber laser inezinzuzo zosayizi omncane, izindleko eziphansi zokusebenza, impilo ende yesevisi, ukuzinza okuhle kanye nekhwalithi ephezulu ye-beam.Khonamanjalo, ukukhanya okukhishwa i-fiber laser kungu-1070nm wavelength enezinga eliphezulu lokumunca, izinga lokuguqulwa kwesithombe sikagesi liphakeme ngokuphindwe ka-10 kunelaser ye-YAG, futhi isivinini sokushisela sishesha kune-YAG ne-CO2 laser.
Welding Technology Revolution
Imishini yokushisela i-laser enamandla amakhulu kulindeleke ukuthi isetshenziswe ekushiseleleni i-aluminium alloy
Njengenqubo ye-welding-energy-density welding, i-laser welding ingavimbela ngempumelelo amaphutha abangelwa izinqubo ze-welding zendabuko, futhi i-coefficient yamandla we-welding nayo izothuthukiswa kakhulu.Kusenzima ukusebenzisa umshini wokushisela we-laser onamandla aphansi ukushisela amapuleti aminyene we-aluminium alloy, hhayi kuphela ngoba izinga lokumuncwa kwe-laser beam endaweni ye-aluminium alloy surface liphansi kakhulu, kodwa futhi kusenenkinga yomkhawulo lapho idingeka. i-welding yokungena ejulile.
Isici esidonsa amehlo kakhulu somshini wokushisela i-aluminium alloy laser welding ukusebenza kahle kwawo okuphezulu, okusetshenziswa ekushiseleleni okujulile kokuqina ukuze kusetshenziswe.Futhi lobu buchwepheshe bokushisela obunobukhulu obukhulu buzoba intuthuko engenakugwemeka esikhathini esizayo.Ngenye indlela, lokhu kushisela ukungena kobukhulu obukhulu obukhulu kugqamisa isenzakalo se-pinhole kanye nomthelela wayo ku-weld porosity, okwenza indlela yokwakheka kwe-pinhole nokulawula kwayo kubaluleke kakhulu, futhi kuzoba yinguquko emhlabeni wokushisela esikhathini esizayo.
