Izindaba - Zingaki izinhlobo ze-laser welding ozaziyo?

1 I-laser brazing

(1) Isimiso

I-laser brazing iyindlela yokushisela esebenzisa i-laser njengomthombo wokushisa, isebenzisa izinto ezinephuzu elincibilikayo eliphansi kunesisekelo sensimbi njenge-filler metal (ebizwa ngokuthi i-solder), ngemva kokushisa nokuncibilika, isebenzisa i-solder ewuketshezi ukumanzisa isisekelo sensimbi, igcwalise igebe elihlangene futhi sabalalisa ngesisekelo sensimbi ukuze uzuze ukuxhumana, njengoba kuboniswe esithombeni esilandelayo.

(2) Izici

Inqubo ye-laser brazing isetshenziselwa i-welding, engenzi nje kuphela umkhiqizo omuhle kakhulu futhi ithuthukise ukubekwa uphawu, kodwa futhi ithuthukisa kakhulu amandla endawo yokushisela futhi ithuthukise ukusebenza kokuphepha kwemoto.Imodi yoxhumano lwensimbi eyisisekelo ingeyohlangano lwe-crimping butt, njengoba kuboniswe esithombeni esingezansi.

(3) Indawo yokufaka isicelo

I-Laser brazing iyinqubo yokushisela esetshenziswa kabanzi yokushisela umzimba wezimoto njengamanje.Inzuzo yayo eyinhloko ukuthi ingakhiqiza ubuso obushelelezi futhi igweme ukuncibilika kwe-zinc enamathela.Isetshenziselwa kakhulu: inhlanganisela phakathi kwepuleti elingaphandle lodonga oluseceleni kanye nepuleti elingaphandle lekhava elingaphezulu (njengoba kuboniswe kuMfanekiso 1 kanye noMfanekiso 2, umucu wokuvala wenjoloba ophahleni uyakhanselwa, omuhle futhi wonga izindleko);Hlanganisa izingxenye ezingaphezulu nezingezansi zephaneli yangaphandle yesivalo se-trunk (njengoba kubonisiwe kuMfanekiso 3)

2 I-laser fusion welding

(1) Isimiso

I-laser fusion welding iyindlela yokushisela esebenzisa i-laser njengomthombo wokushisa ukuze incibilikise ingxenye yesisekelo sensimbi yamapuleti amabili ekhoneni elihlangene lamapuleti amabili (ngasikhathi sinye, ncibilikisa intambo yokushisela eseduze ukuze ugcwalise ilunga lekhona lamapuleti amabili) ukuze yakha insimbi ewuketshezi, bese yenza ukuxhumana okuthembekile ngemva kokuphola.Umgomo wayo wenqubo uboniswa kuMfanekiso 3.

(2) Izici

I-laser fusion welding ingahlukaniswa ibe i-laser penetration welding, i-laser fusion welding (ngaphandle kokugcwalisa ucingo) kanye ne-laser fusion wire filling welding.Isetshenziselwa kakhulu ukushisela ingxenye engaphambili yemoto, ikhava engaphezulu kanye nephansi, iphaneli yomnyango wangaphakathi, njll. Isisekelo sensimbi sixhunywe ngokuqhwanda, njengoba kuboniswe kuMfanekiso 4.

(3) Indawo yokufaka isicelo

I-laser fusion welding isetshenziswa kakhulu ophahleni nasesembozweni somnyango.Umfanekiso wesi-5 ukhombisa ukusetshenziswa kwe-laser fusion welding emnyango ongemuva wemoto.
