Tlhahisong ea mehleng ea kajeno, ts'ebeliso eaMechini ea 2000W fiber laser weldingbakeng sa tjheseletsa aluminium tšepe e ntse e ata ka ho eketsehileng.Leha ho le joalo, ho netefatsa boleng le polokeho ea welding, lintlha tse latelang tsa bohlokoa li hloka ho hlokomeloa.
1. Phekolo ea holim'a metsi pele ho tjheseletsa
Filimi ea oxide e holim'a tšepe ea aluminium e ka ama boleng ba welding haholo.Phekolo e phethahetseng ea holim'a metsi e tlameha ho etsoa ho tlosa filimi ea oxide, litšila tsa oli le litšila tse ling.Ha k'hamphani e 'ngoe ea likarolo tsa koloi e tjheseletsa foreimi ea aluminium, ka lebaka la ho hlokomolohuoa kalafo ea holim'a metsi, palo e kholo ea li-pores le mapetsong a ile a hlaha ka har'a weld, mme sekhahla sa ho tšoaneleha se ile sa theoha haholo.Kamora ho ntlafatsa ts'ebetso ea kalafo, sekhahla sa thuto se nyolohetse ho feta 95%.
2. Khetho ea Mekhahlelo e Loketseng ea Welding
Mekhahlelo ea welding joalo ka matla a laser, lebelo la welding le boemo ba ho tsepamisa maikutlo li bohlokoa haholo.Bakeng sa lipoleiti tsa aluminium tse nang le botenya ba 2 - 3mm, matla a 1500 - 1800W a loketse haholoanyane;bakeng sa ba nang le botenya ba 3 - 5mm, 1800 - 2000W e loketse.Lebelo la welding le lokela ho ts'oana le matla.Ka mohlala, ha matla a 1800W, lebelo la 5 - 7mm / s le loketse.Sebaka sa ho tsepamisa maikutlo se boetse se ama phello ea welding.Sepheo sa lipoleiti tse tšesaane li holim'a metsi, ha lipoleiti tse teteaneng li hloka ho teba ka hare.
3. Taolo ea ho Kena ha Mocheso
Aluminium tšepe e na le conductivity e phahameng ea mocheso 'me e atisa ho lahleheloa ke mocheso, e amang ho kenella ha weld le matla.Ho hlokahala taolo e nepahetseng ea ho kenya mocheso.Mohlala, ha khoebo ea sepakapaka e ne e tjheseletsa likarolo tsa aluminium, taolo e fosahetseng ea ho kenya mocheso e lebisitse ho sa phethahalang ho kopanngoa ha cheselle.Bothata bo ile ba rarolloa ka mor'a ho ntlafatsa ts'ebetso.
4. Tšebeliso ea Khase ea Shielding
Khase e sireletsang e nepahetseng e ka thibela oxidation ea weld le porosity.Argon, helium kapa metsoako ea bona e sebelisoa hangata, 'me lebelo la phallo le tataiso ea ho foka li lokela ho lokisoa hantle.Lipatlisiso li bontša hore tekanyo ea phallo ea argon ea 15 - 20 L / min le tataiso e nepahetseng ea ho fofa e ka fokotsa porosity.
Nakong e tlang, ho lebeletsoe hore lisebelisoa tse matla le tse bohlale ho feta tsa laser tjheseletsa li tla hlaha, 'me mekhoa e mecha ea li-welding le lisebelisoa li tla khothalletsa tšebeliso ea eona e pharaletseng.Qetellong, ke feela ka ho latela litemoso tsena, ho bokella boiphihlelo le ho ntlafatsa ts'ebetso moo melemo ea laser welding e ka hlahisoang ho kenya letsoho ntlafatsong ea indasteri ea tlhahiso.
