Yiziphi Izinsimbi Ezivamile Ezisetshenziswa Ku-Laser Welding?

Impumelelo yensimbi ngelaser weldingkuncike ezicini zayo eziyisisekelo. Isibonelo, ukukhanya okuphezulu kungaphazamisa amandla e-laser, kuyilapho ukuhanjiswa kwe-thermal ephezulu kuqeda ukushisa ngokushesha kakhulu endaweni yokushisela. Lezi zici, kanye nephuzu lokuncibilika, zinquma ukuthi into ethile iwamunca kahle kangakanani amandla ukuze kwakhe ukushisela okuqinile, okunembe.

Nakhu ukuhlukaniswa kwezinsimbi ezivamile nokuthi izakhiwo zazo ziqala ukusebenza kanjani.

I-Laser Welding Carbon Steel

I-Carbon steel iyingxube ye-iron-carbon enekhabhoni efinyelela ku-2.1%. Okuqukethwe kwekhabhoni kuyisici esiyinhloko sezakhiwo zayo.

Insimbi enekhabhoni ephansi(ngaphansi kuka-0.25% ikhabhoni) i-ductile, iqinile, futhi ihlelwa kalula futhi iyashiseka. Ivamise ukusetshenziselwa amaphaneli omzimba, izintambo, namapayipi.

Medium-carbon steel(0.25% kuya ku-0.60% carbon) inamandla futhi ilukhuni kunensimbi enekhabhoni ephansi. Lokhu kuyenza ifanele izinto ezidinga amandla engeziwe nokumelana nokugqokwa njengamagiya, shafts, namasondo kaloliwe.

High-carbon steel(ngaphezu kuka-0.60% ikhabhoni) inamandla futhi inzima kakhulu kulawa amathathu, kodwa futhi iyi-ductile encane futhi ephuka kakhulu. Ukuqina kwayo kuyenza ilungele amathuluzi okusika, iziphethu, nezintambo eziqine kakhulu, kodwa idinga ukuphathwa ngokucophelela ngesikhathi sokushisela ukuvimbela ukuqhekeka.

I-Carbon steel iyihhashi lokusebenzela ekukhiqizeni, futhi idinga ukushisela i-laser kahle.

Izinzuzo: Uthola ama-welds aqinile, ajulile ngokunemba okumangalisayo nokuhlanekezela okuncane kakhulu. Ijubane liyinhlanganisela enkulu, ethuthukisa ukukhiqiza phansi kwefekthri.

Ukucatshangelwa: Ukupholisa okusheshayo kwenqubo ye-laser kungenza i-weld ibe brittle futhi ithambekele ekuqhekekeni. Ngezinye izikhathi, ukushisa kuqala ingxenye kuyadingeka ukunciphisa ukupholisa nokuvimbela izinkinga.

I-Laser Welding Stainless Steel

Lona umdlalo owenziwe ezulwini. I-laser welding iyinqubo ephelele yensimbi engagqwali, ikakhulukazi ezimbonini ezifuna ukuhlanzeka.

Izinzuzo: Okokufaka okuphansi, okugxilile kokushisa kuwukuwina okukhulu. Ilondoloza izakhiwo zensimbi engagqwali ezimelana nokugqwala ngokuvimbela okuthile okubizwa ngokuthi “imvula ye-carbide.” Lokhu kubangela ukushisela okuhlanzekile ngokuhlinzwa futhi okunembayo, yingakho kudume kakhulu ezimbonini zezokwelapha nezokudla.

Ukucatshangelwa: Izinsimbi ezingenasici ezivame kakhulu, njengochungechunge lwama-300 (isb, 304, 316), zishisela kahle kakhulu. Kodwa-ke, amanye amabanga, njengochungechunge lwe-400, angaba brittle endaweni ethinteke ukushisa.

I-Laser Welding Aluminium

I-aluminium yokushisela ibilokhu ikhohlisa, kepha i-laser welding iyawushintsha umdlalo.

Izinzuzo: I-Aluminium iwumqhubi omkhulu wokushisa, okusho ukuthi nge-welding yendabuko, ukushisa kuyasakazeka futhi kubangele yonke ingxenye ukuthi igoqe. Amandla agxilile e-laser nokokufaka kokushisa okuphansi kuxazulula le nkinga, kunciphisa kakhulu ukuhlanekezela.

Ukucatshangelwa: I-Aluminium ikhanya kakhulu. Indawo ecwebezelayo ingabhampa i-laser beam khona lapho. Impumelelo incike ezintweni ezimbalwa ezibalulekile: ukuhlanza indawo okungenabala, igesi evikelayo efanele, kanye nokusebenzisa uhlobo olulungile lwelaser (ama-fiber lasers avame ukuthandwa) ukuze kuqinisekiswe ukuthi amandla ayamuncwa.

I-Laser Welding Titanium

Uma udinga ukushisela i-titanium, i-laser ingelinye lamathuluzi akho angcono kakhulu omsebenzi.

Izinzuzo: I-Titanium iyinsimbi esebenzayo, okusho ukuthi ingcoliswa kalula umoya-mpilo osemoyeni lapho incibilika, okuholela ekushiseleleni okubuthakathaka, okuphukayo. Isivinini se-laser nokunemba kunciphisa isikhathi insimbi incibilika futhi ivezwe ngaso, kunciphisa ingcuphe yokungcoliswa kanye ne-embrittlement.

Ukucatshangelwa: Njenge-TIG welding titanium, kusadingeka uqaphe kakhulu. Ukuhlanzeka okuphelele nokuvikela okuphelele ngegesi engasebenzi (njenge-argon) akuxoxiswana ngakho.

I-Laser Welding Copper kanye Nezinye Izinsimbi Ezibonisayo

Yilapho i-laser welding icindezela khona imingcele yalokho okungenzeka.

Izinzuzo: Umshini wokushisela we-laser ungajoyina izinto ezikhanya kakhulu njengethusi, okunzima ngendlela emangalisayo ukushisela cishe nganoma iyiphi enye indlela. Lokhu kubalulekile ezinhlelweni ezifana namabhethri emoto kagesi (EV), lapho kufanele kuhlanganiswe ithusi ne-aluminium.

Ukucatshangelwa: Lezi yizinto ezisezingeni lochwepheshe. Ukubonakala okuphezulu kanye ne-thermal conductivity empeleni kungalimaza i-laser optics uma ingaphathwa ngendlela efanele. Ngokuvamile kudinga imishini ekhethekile, kanye namasu athuthukile.

Yini ama-Lukulingisa i-Laser Welding?

Nakuba kuzwakala njengethuluzi eliyisimangaliso, aliphelele kuwo wonke umsebenzi. Kubalulekile ukuqonda ukuhwebelana.

1.Izindleko Zokuqala Eziphezulu: Umshini wokushisela we-laser ochwepheshe uwutshalomali olubalulekile, obiza kakhulu kunokusetha kwe-MIG okungokwesiko noma kwe-TIG.

2.Izidingo Ezihlangene Eziqinile: Njengoba kushiwo, ama-laser adinga ukulingana okuseduze. Uma izingxenye zakho zinezikhala noma zingasikiwe kahle, i-laser ngeke ikwazi ukuvala ibhuloho ngempumelelo.

3.Izinkinga zokucabanga: Izinto ezicwebezelayo njenge-aluminium nethusi zingaba nzima ukushisela ngaphandle kwama-lasers akhethekile namasu.

4.Ukuphepha Ukukhathazeka: I-laser yokuqina okuphezulu iyingozi kakhulu futhi ingabangela ukulimala okukhulu kwamehlo nokushiswa kwesikhumba, ngisho nokuboniswa. Izivalo ezifanele zokuphepha kanye nempahla yokuzivikela yomuntu siqu (i-PPE) kuyimpoqo ngokuphelele.

Imikhuba Engcono Kakhulu Ye-Laser Welds engenasici

Ukuze uthole okuningi ngenqubo yakho yokushisela i-laser, udinga ukubethela okuyisisekelo.

Ukulungiselela kuyinto yonke

I-Joint Fit-Up: Ngeke sikusho ngokwanele: izingxenye zakho kufanele zihlangane ngokuqinile. Khomba igebe elingaphansi kuka-10% wogqinsi lwezinto ezibonakalayo ukuze uthole imiphumela ehamba phambili.

Ukuhlanza ubuso: Lahla konke okungeyona insimbi. Lokhu kusho ukususa wonke amafutha, amafutha, ama-oxides, nokunye ukungcola. Indawo ehlanzekile ibalulekile ukuvimbela ama-pores nokunye ukukhubazeka ekushiseleni kwakho.

Lawula Inqubo Yakho

I-Shielding Gas: Njenge-TIG ne-MIG, i-laser welding isebenzisa igesi ye-inert (imvamisa i-argon noma i-helium) ukuvikela ichibi lokushisela elincibilikisiwe ku-oxygen ne-nitrogen emoyeni, iqinisekisa ukushisela okuqinile, okuhlanzekile.

Ukuthuthukiswa Kwepharamitha: Kufanele udayele izilungiselelo zakho. Amandla e-laser, isivinini sokushisela, kanye nebanga lokugxila kumele kulinganiswe kahle kunto ethile nogqinsi osebenza ngalo.

Ukuphepha Okokuqala, Njalo

Ukushisela nge-laser akuyona inqubo ongazithatha kalula ngayo. Ukukhanya okugxilile kunamandla amangalisayo. Noma ubani oseduze nomsebenzi kufanele agqoke izingilazi zokuphepha ezikhethekile ze-laser ezilinganiselwe ubude obuthile be-laser yakho.

Ingabe Umshini Welding We-Laser Uyisinqumo Esilungile Kuwe?

Ngakho-ke, kufanele utshale imali ku-laser welding?

Ake siphinde. I-Laser Welding iyithuluzi lokukhiqiza elithuthukisiwe eliletha isivinini esingenakuqhathaniswa, ukunemba, kanye nekhwalithi. Ukuhwebelana yizindleko eziphezulu zokuqala kanye nezidingo eziqinile zezingxenye ezihlanzekile, ezilingana kahle.

Umcabango wethu wokugcina: Uma umsebenzi wakho ufuna ivolumu ephezulu, ukuzenzela, nokukhomba ukunemba—ikakhulukazi ezintweni ezithambile noma eziyinselele—khona-ke i-laser welding akuyona nje enye inketho. Isixazululo esiphezulu esingaguqula ukukhiqiza kwakho.
