I-laser welding
Emkhakheni wokuxhumana kwezinto ezibonakalayo, ukushiswa kwe-laser enamandla amakhulu kuthuthuke ngokushesha, ikakhulukazi ekukhiqizeni izimoto zendabuko kanye nokukhiqizwa kwezimoto ezintsha zamandla.Ngokuzayo, isidingo embonini ye-aerospace, imboni yokwakha imikhumbi, imboni ye-petrochemical kanye neminye imikhakha izokhula kancane kancane, ikhuthaze ukuthuthukiswa kobuchwepheshe bezimboni ezihlobene.
01 Imboni yendabuko yokukhiqiza izimoto
Njengamanje, ingxenye enkulu yemboni yokushisela i-laser isembonini yokukhiqiza izimoto, futhi lesi simo ngeke sishintshe eminyakeni embalwa ezayo, futhi imakethe izoqhubeka nokugcina isidingo esikhulu.Ubuchwepheshe be-laser welding buhlanganisa i-laser self fusion welding, i-laser filler wire fusion welding, i-laser filler wire brazing, i-remote scanning welding, i-laser swing welding, njll. , ukuze kubonakale isisindo esilula, ukonga amandla, ukuvikelwa kwemvelo nokuphepha kwemoto [1].Ukukhiqizwa kwezimoto zesimanje ngokuvamile kuthatha imodi yomugqa wokukhiqiza othomathikhi.Kungakhathaliseki ukuthi yisiphi isixhumanisi esinengozi yokuvala shaqa, sizodala ukulahlekelwa okukhulu, okuphinde kubeke phambili izidingo eziphakeme zokuzinza nokuthembeka kwemishini kusixhumanisi sokukhiqiza ngasinye.
Njengeyunithi eyinhloko yemishini yokushisela i-laser, i-laser idinga ukuba nokuzinza okuphezulu kwamandla okukhipha, amashaneli amaningi, i-anti anti high anti high anti high anti high anti reaction ikhono, njll. U-Ruike Laser wenze umsebenzi omningi kulo mkhakha. futhi ikhiqize imishini yokushisela ezinzile futhi enokwethenjelwa.
02 Imboni entsha yokukhiqiza izimoto
Imboni entsha yezimoto zamandla ithuthuka ngokushesha, ngokukhula okuqhubekayo ekuthengisweni komhlaba wonke kanye nasekhaya.Isidingo sezingxenye zayo eziyinhloko, njengamabhethri kagesi nama-drive motors, siyakhula;
Noma ngabe ukwakhiwa kwebhethri lamandla noma i-motor yokushayela, kunesidingo esikhulu se-laser welding.Izinto eziyinhloko zalawa mabhethri amandla, njengebhethri yesikwele, ibhethri le-cylindrical, ibhethri yephakheji elithambile nebhethri ye-blade, i-aluminium alloy nethusi elibomvu.I-Hair Pin motor iyinkambo yentuthuko yesikhathi esizayo yemoto yokushayela.Ama-windings namabhuloho ale motor konke kuyizinto zethusi ezibomvu.Ukushiselwa kwalezi zinto ezimbili “eziphakeme ezikhombisa ukukhanya” bekulokhu kuyinkinga.Ngisho noma kusetshenziswa i-laser welding, asekhona amaphuzu obuhlungu - ukwakheka kwe-weld, ukusebenza kahle kwe-welding kanye ne-welding spatter.
Ukuze kuxazululwe lezi zinkinga, abantu baye benza ucwaningo oluningi, okuhlanganisa ukuhlola inqubo yokushisela, ukwakhiwa kwamajoyinti okushisela [2], njll. kuthuthukiswe, kanye nokusebenza kahle kokushisela kungathuthukiswa ngezinga elithile;Ngokuklanywa kwamajoyinti okushisela ahlukile ahlukile, njengamajoyinti wokushisela, amajoyinti we-welding we-wavelength amabili, njll., ukwakheka kwe-weld, i-welding spatter kanye nokusebenza kahle kwe-welding kungathuthukiswa kakhulu.Kodwa ngokukhula okusheshayo kwesidingo, ukusebenza kahle kwe-welding namanje akukwazi ukuhlangabezana nezidingo.Izinkampani ezinkulu zomthombo wokukhanya we-laser zethule ama-laser okukhanya angalungiseka ngokuthuthukiswa kobuchwepheshe kwama-lasers.Le laser inemiphumela emibili ye-coaxial laser beam, futhi isilinganiso samandla salokhu okubili singalungiswa ngokuthanda kwakho.Lapho ushisela i-aluminium ingxubevange nethusi elibomvu, ingafinyelela umphumela wokushisela osebenza kahle futhi wokuchaphaza wamahhala, ihlangabezane ngokugcwele nezidingo zamanje zemboni yezimoto zamandla amasha, okuzoba i-laser evamile embonini eminyakeni embalwa ezayo.
03 Inkundla yokushisela yamapuleti aphakathi nendawo nawugqinsi
Ukushiselwa kwamapuleti aphakathi nendawo nawugqinsi kuyindlela enkulu yempumelelo ye-laser welding esikhathini esizayo.Emkhathini, kwi-petrochemical, ukwakha imikhumbi, okokusebenza kwamandla enuzi, ezokuthutha ngojantshi nezinye izimboni, sikhulu isidingo sokushisela amapuleti aphakathi nendawo nawugqinsi.Eminyakeni embalwa edlule, kunqunyelwe amandla, amanani kanye nobuchwepheshe bokushisela bama-lasers, ukusetshenziswa nokukhuthazwa kwe-laser welding kulezi zimboni kuhamba kancane.Eminyakeni emibili yakamuva, isidingo sokuthuthukiswa kwezimboni kanye nokuthuthukiswa kokukhiqiza embonini yaseShayina sesiphuthuma kakhulu.Ukuthuthukisa ikhwalithi nokusebenza kahle kuyisidingo esivamile sayo yonke imikhakha yempilo.I-laser arc hybrid welding ibhekwa njengobunye bobuchwepheshe obuthembisayo bokushisela amapuleti aphakathi nendawo.
